So I just finished upgrading OmniOS (r151004 -> r151008) and Napp-it (0.9b3 -> 0.9d2). After I updated Napp-it, I ran
Code:
wget -O - www.napp-it.org/afp | perl
to update netatalk from 3.0.3 to 3.0.4 and then reboot. Now netatalk isn't working. Did I do something wrong? How can I fix it? I googled the errors but didn't see anything obvious.

Code:
-bash-4.2$ uname -a
SunOS ALINEA 5.11 omnios-6de5e81 i86pc i386 i86pc

Code:
running version : 0.9d2 nightly Nov.03.2013

Here is what I found in /var/adm/messages:

I have tried to setup AFP with a new install on OmniOS 1008 and failed the same way.
My other config (OmniOS1006 with AFP installed and then updated to 1008 work)

I believe you because the older AFP was working on 1008 for me prior to me upgrading using wget. Can I roll that back somehow?

So apparently installing AFP on top of OmniOS 1008 is not the correct order of operations? Are you suggesting I should reinstall OmniOS 1006, then install AFP, then upgrade to 1008? How do I install 1006 now that it's not the most current stable release?

I've never reinstalled OmniOS.. how do I retain my settings and carryover my zpools? How do I backup and restore the napp-it settings? I obviously am very cautious about this because I do not want to lose any data.

With ZFS there is no danger for your data. Even if you reinstall OmniOS on same or different hardware, you only need a pool-import and your data is there.
Even a reinstall of napp-it is no problem. Beside job and appliance group settings there is nothing important there. You can backup/restore the files below /var/web-gui/_log to keep these settings.

In your case, you can benefit from a different Solaris feature: BE=boot environments. These are bootable system snapshots. Select a state prior your re-installation of netatalk during boot and check if its working. If so, activate this BE as default (Menu snapshots - Bootenvironment, try them going back in time until you find a working one) .

If the last working was the 1006 BE, you need to update to 1008 again.

So I installed OmniOS from scratch using the 151006 USB stick installer. I left things at 151006 (all I did was configure an IP and user). Then I installed napp-it, rebooted, then afp, rebooted. AFP is still not starting and throwing the same error:

It depends on the speed and size of disk. On my RAID pool, it runs with around 80MB/s.

I had a question about iSCSI/COMSTAR best practices.

Because of limitations in the free backup tool I use to write shit to tape, I need to convert all my CIFS shares into raw iSCSI storage space mapped to a windows file server.

What is the best way to convert a raw, empty pool into usable iSCSI space? Currently I set up a volume that consumes ~90% of the capacity of the entire pool, and map the volume as a COMSTAR logical unit.
My other options include making a single thin provisioned LU, and then doing a full format in windows to balloon out the file to prevent later space related 'oops'.

I'm leaning more towards the thin provisioning, just because it seems less janky than having to create a volume under each pool (which has to be a multiple of the pool cluster/stripe size), then making an LU out of it.

Any thoughts or links to any kind of iSCSI best practices for this would be super appreciated, I desperately need to get all my data spooled off to tape.

The problems is that there is a dependency with an external sasl2 library.
During netatalk setup this library is installed but now it creates a newer library instead the libsasl2.so.2 library file.

Please rerun the wget-afp installer as it should solve the problem now (On OmniOS 1006 and 1008)

Comstar iSCSI is very fast and you can use it with a Windows server for special Windows features that need ntfs. I would just create a volume (90% is too much - keep some space for snaps).

Main problem: If you need files from a snap, you must clone or rollback the whole filesystem to have access (You may use Windows shadow copies that this is not at the same level like ZFS snaps). This is unlike a pure Solaris SMB server where you have a filebased access to snaps via Windows previous version. There must be a very important reason to loose this feature beside the stability and simplicity of a Solaris SMB server. In my own config I was happy for every Windows server that i was able to replace with a Solaris server. My last Windows server are several AD server and a Windows webserver where I need Windows AD credidentials.

This fixed it. Thanks.

Next problem.. now my sharing is no longer working. I guess those settings don't carry over after a rebuild. I have no idea how I had this working before, but I need napp-it to host my SMB shares, NFS exports, and AFP shares all on the same files.

I currently have a local user added through napp-it working so that my windows desktop can read and write to folders on the SMB share, but I can't seem to delete the files I create. Permission denied.

Next, I have a linux desktop that mounts the same share via NFS, and I can only modify the files as root. I need to be able to view, modify the files as the same user (same unix and windows usernames).

I also need to be able to manage this using my Mac AFP share of the same filesystem. Read, write, modify the files.

This always seems so hard for me.. I've looked at the guides again, and I can't seem to find the clear instructions on how to set up sharing in this type of environment.

Seems like you forgot to reboot after installing AFP.
The AFP installer creates a BE and activates this BE.You are asked to reboot, If you do not every change is not in the next default BE

AFP, NFS and SMB are highly incompatible
- NFS (v3) connects without authentication based on client ip on a good will base, different on every OS
- AFP authenticates and use Unix UID/GID and Unix permissions but respects ACL
- SMB authenticated and use Windows SID and ACL only

So the only minimal common sense is setting permission to allow everyone. I would at least set NFS to allow everyone If you need authentication, go SMB all the way and use AFP/NFS only when absolutely needed (Even Apple moves to SMB as the default protocol in 10.9 Maverick)

I did reboot and I'm working from the netatalk-3.1 BE now.

Okay.. so I didn't know that Mavericks dropped AFP. I guess that means so can I! I do have a number of Ubuntu 12.04 and Windows+Mac clients, so I'll still need a mixed environment of NFS and SMB. Does that make this situation easier?

I am not really comfortable with world read and definitely not world write. My concern is less about security or privacy (although certainly important on its own), but more about data integrity (accidental deletion or modification).

Maverick did not drop AFP. They need it at least for TimeMachine but Apple declared the move to SMB as the default protocal.

NFS is the real problem as it use only the client IP to restrict access. I would use NFS only where I need the performance (like ESXi datastore or video editing for Macs) on a trusted network with permissions/ ACL like everyone@=modify - best with a aclmode=restricted ZFS setting to hinder all clients to modify permissions with a chmod command (AFP will not work with such a setting)

Data integrity depends not only on the protocol. For this you have vlans, ZFS and snaps too - and authentication that is missing on NFS3-

So my linux use cases are not terribly demanding on performance.... should I completely ditch NFS on my network and just go pure SMB? I've never considered that.. I suppose I could still automount and such over SMB.

Okay, so starting over now (first the rebuilt OmniOS, now the re-architecting my network shares), if I want pure SMB sharing, what's the best way to set that up securely? Add local users and groups via napp-it, set ACLs on Napp-it for each folder? Is there any benefit to setting each folder as its own ZFS fileshare, or can I accomplish all of this with just 1 ZFS fileshare and proper permissioning via ACLs?

There is no best of all technical solution. You must find one for your needs. Main aspect is if you need user authentication or not (NFS, SMB with guest=on)

On my pair of mirrored drives, one disk with smart errors is causing problems with access time and listing of files. Is there a way to shut off the bad disk, retrieve some of the files I need from the pool? My replacement comes tomorrow/weekend, but I need some files now.

My tape backup program is more or less windows only, and needs to use VSS to take the backups. They don't have a linux client worth a shit, much less a solaris one. So in order to spin all my stuff to tape, I need to use iSCSI volumes mapped directly to the file server I spin up.

Unless you know of a backup solution I can use directly on OmniOS that gives me the ability to spin data directly to a SuperLoader 3 tape deck.

Sorry, I do not have an overview about tape based backup solutions. I through out my tape backup years ago and use now three ZFS backup systems (two inhouse, one external) with many snaps for the last year.

If you cannot go this way, you may use a Windows backupserver where you sync (robocopy or rsync) all files from ZFS snaps. This gives you a realtime backup server with the ability to do your tape backups from VSS

If your backupsolution can do backups without VSS from SMB shares or network mounted driveletters, you may mount ZFS snaps for tape backups.

If you need your tape solution to backup open Windows databases etc, you can go the iSCSI way.

I have updated my free preconfigured ESXi webbased-ZFS storage-appliance VM (napp-in-one) v. 13b to OmniOS 1008 stable

- and added a second one (14a) for testings that includes all services and add-ons like netatalk 3.1, proftpd, Apache with MySQL, MySQLAdmin, Owncloud, tftpd, rsync 3.1 or the Mediatomb DLNA server

- both together with a napp-it 0.9e1 preview that introduces ftp, iSCSI and www (virtuel server) as a ZFS filesystem property

Next 0.9e contains 5 new day-trigger:
- mon-fri
- mon-sat
- sat-sun
- first-sat
- first-sun

The following two aren't working on my napp-it 0.9e2. Haven't checked the others yet.

- sat-sun
- mon-sat

Has somebody tried the new day triggers with success?

So I'm running into an issue with my new SAN host setup. I'm running a Supermicro X9SRi motherboard, Xeon E5 proc, and 32 GB of ECC UDIMMs. It's all in a Supermicro 24 bay case with the EC26 SAS expander.

I built the server out with OmniOS, the latest stable build, and ran a pkg update on it to bring it to current.

Currently there is a Intel 520-DA 10GbE card in it, as well as my LSI 9211-8i card. I imported two of my old pools, a 8 disk raidz2 made of 1.5 TB WD Green drives (I KNOW they're awful), and another 10 disk raidZ2 made of 3TB reds.

I ran a scrub on both pools since I haven't done so in a few months, and the system is crashing our and core dumping. Below is the system logs. I think my 2.5 year old LSI card is finally starting to crap out on me, but it could be something else. RAM is ECC and passes memtest just fine. Based on what I understand of the logs, the system tries to talk to the card, and the card doesn't respond correctly, and the system faults because it suddenly lost the hardware.

Anyone have an idea?

I would attach the disks directly without expander to the 9211 + Sata ports and retry to check if the expander is the problem.

Comstar iSCSI is very fast and you can use it with a Windows server for special Windows features that need ntfs. I would just create a volume (90% is too much - keep some space for snaps).

Main problem: If you need files from a snap, you must clone or rollback the whole filesystem to have access (You may use Windows shadow copies that this is not at the same level like ZFS snaps). This is unlike a pure Solaris SMB server where you have a filebased access to snaps via Windows previous version. There must be a very important reason to loose this feature beside the stability and simplicity of a Solaris SMB server. In my own config I was happy for every Windows server that i was able to replace with a Solaris server. My last Windows server are several AD server and a Windows webserver where I need Windows AD credidentials.

Gea, do you have recommendations for using a ZFS share as the wwwroot for IIS or a simple ubuntu LAMP server? A NFS share shows up as a network drive in windows, which i dont think IIS lets you use as a wwwroot directory. What about just a samba mount in linux? Can you set your document root to a samba share in linux? Unfortunately we cannot use LAMP directly on our omni server due to various compatibility issues.

So I'm running into an issue with my new SAN host setup. I'm running a Supermicro X9SRi motherboard, Xeon E5 proc, and 32 GB of ECC UDIMMs. It's all in a Supermicro 24 bay case with the EC26 SAS expander.

I built the server out with OmniOS, the latest stable build, and ran a pkg update on it to bring it to current.

Currently there is a Intel 520-DA 10GbE card in it, as well as my LSI 9211-8i card. I imported two of my old pools, a 8 disk raidz2 made of 1.5 TB WD Green drives (I KNOW they're awful), and another 10 disk raidZ2 made of 3TB reds.

I ran a scrub on both pools since I haven't done so in a few months, and the system is crashing our and core dumping. Below is the system logs. I think my 2.5 year old LSI card is finally starting to crap out on me, but it could be something else. RAM is ECC and passes memtest just fine. Based on what I understand of the logs, the system tries to talk to the card, and the card doesn't respond correctly, and the system faults because it suddenly lost the hardware.

Anyone have an idea?

Oh man, these are the EXACT specs of a server i am building for myself. I haven't purchased parts yet, but please keep us updated on your issue. I am curious to see if the straight through backplane fixes it.

I would attach the disks directly without expander to the 9211 + Sata ports and retry to check if the expander is the problem.

I had them plugged straight into the card with my old Norco 4224 case, and the system would mysteriously hang then reboot, without even core dumping, so I can assume that either it just deeply doesn't like the flaky disks (during the scrub it repaired ~1 MB on 4k bad sectors, with 30+ HW failures in iostat -xen on 3 of the 8 disks in the pool), the firmware/config/card is flaky, or there is something else.

When it fails, the activity light on one disk stays solid, the rest drop off and sit silent, and a zpool status will hang. Hopefully I can just replace these shitty WD Greens and be done with it.

I would not expect problems with IIs and wwwroot on a SMB network share nor with Linux and SMB or NFS mounts.

ps
What's your compatibility problem with LAMP on OmniOS?

the dev doesn't know solaris really and i think drupal has a bunch of dependencies that it wouldn't be able to satisfy.

also, UNRELATED BUG:
I just came across a weird bug in .9d2 nightly running OI today. Any appliance that has an exclamation point at the end of the operator password fails to add to the extensions->add appliance menu. If i change the password to not have an exclamation point then the appliance adds fine. Not sure if you knew about it, i know its a slightly older version of napp-it. Just figured id give you the heads up

While you may get all what is needed from the SmartOS repo that is working wth OmniOS/OI as well, see http://pkgsrc.joyent.com/packages/SmartOS/2013Q3/x86_64/www/ - I understand the position to prefer a alreadytested config. (howto install, see http://www.napp-it.org/downloads/binaries_en.html)

About the password problem
You should follow the restriction from the napp-it setting menu (allowed: [a-zA-Z0-9,.-;:_#]) as you have the additional layers Perl, Html and a webserver where special characters may have special meanings and must be processed separately when needed.

Thanks gea! It amazes me that you are able to stay on top of so many threads on so many different forums! I had completely overlooked your password recommendations, my fault.

One last question, i promise! Does napp-it do any sort of "padding" when initializing disks and creating pools so that a drive from a different vendor with slightly smaller/larger sectors will still work?

Hi guys, I am building a new ZFS server for production use.

I have the following specs but I am not exactly sure if I have enough RAM and how I should split the L2ARC and the ZIL.

2 x six core Intel CPU
36 x 4TB WD4003FZEX drives, expect to install 9 at the time, 4 mirrors and 1 spare, with a 3-4 month waiting time in between so I dont get all 36 disks from the same batch... dont want all to fail one after another.
256 GB RAM, should I upgrade to 384?
4 x 640GB IO Accelerators for ZIL and L2ARC, they show up as 2x300GB disks when installed so it means I have 8 x 300GB showing, I thought I would use 2 x 2 mirror for ZIL and the last 4 striped for L2ARC - I am not sure whats best here?

It will host virtual machines so I think dedup can be disabled since its unlikely to be able to dedup much at all, I will enable default compression.

does it make any difference if I run Solaris 11.1 with ZFS version 34 instead of OpenIndiana with ZFS version 28?

connectivity is Infiniband 2x40Gbit + 2x10gbit ethernet in case I need to publish LUNS across longer distances...

input on optimal config in terms of cache/dedup/compression is welcome - I expect to end up with 32 drives which will be 16 mirrors and 4 spares. all together 64TB rather fast storage.

br,
Paniolo

No, nothing special within napp-it

Only some hints
- with 4 TB disks, I would think of 3way mirrors due the large rebuild time, increases read perforamce as well
- do you need that many space? VMs are mostly quite small and performance hungry.
Maybee a smaller high performance pool build from good SSDs and a larger pool from multiple Raid-Z2 is an option

- With that many RAM for Arc you may skip the slower SSD L2Arc and add as many RAM as possible.
- You can do L2Arc tests to see if L2ARC helps.
- I do not know, what you mean with 640 GB IO accelerator but I suppose it is maybee a pci-e card with 2 x 320 SSD each.
Are they really good for ZIL regarding latency and small writes? They are mostly optimized for larger reads/writes and good for L2ARC.
- never mix ZIL + any other usage on the same SSD.

Usually the best of all is a 8GB Dram based ZeusRAM followed by SSDs like Intels S3700.
If you have 2 x 40Gb network, you have a theoretical max of about 80 GB network traffic in 10s (you usually scale size to 10s traffic). I do not suppose that you can really do more than about 20 GB so 2-3 x ZeusRAM or one 200 GB Intel S3700 is what I would suggest usually. Maybee your accelerator is very good and a better option.

Avoid dedup in any case. Disable compress or use LZ4 (OmniOS)
I would prefer OmniOS over OI as it is stable and better maintained.

If you use Solaris11.1 you have encryption as the main advantage (not usefull for high performance) and you need a license from Oracle (You really need as iSCSI seems broken and the fix is not free)

How do you backup your storage?

Hi Gea, thanks for replying.

3way mirror would cause me to loose too much data I think. I was planning on 16 vdevs of each 2 disks. I presume a resilver would be max about 24-36 hours? Do you think it will be longer? I do need lots of space.

The IO Accelerator is just a PCI-E with 2x300GB on it, when I test write speed and IOPS on a simple CrystalDiskMark I get around 5000 IOPS on 4K write and a bit more with a Queue Depth of 32, but not much more. Write Speed about 300-350 MB/Sec on 512K sequential write. Latency is good. This is under low to medium load, measured from a VM located on one of the 300GB partitions in vSphere 5.5. If I mirror 2x300GB and another 2x300GB as ZIL will that be too slow? Any idea how much better a ZeusRAM would perform?

What do you mean by "followed by SSDs"? A fast ZeusRAM ZIL + SSD ZIL?

I will try OmniOS, would you prefer it over Solaris 11.1? I don't mind the license/service contract for Solaris.

I have a backup server which will use Veeam to backup the virtual machines to a fiber based SAN, effectively 16Gbit Fiber connection so should be OK speed.

I can also skip dedup and compress, hopefully 64TB should allow ~250 or so Virtual machines.

I cannot say if a ZeusRAM is better than your SSD solution but it is the "best of all" in every pro-config. I have done tests with my ZeusRAM vs an Intel S3700 (one of the best SSDs regarding wirites) and it was about 30% faster.

The followed means
- the best of all is a ZeusRam, the second best solution are SSDs with very fast SLC chips or MLC based ones like the Intel 3700.

I connot comment Oracle Solaris as I do not use. If you like to go the free ZFS route, use OmniOS and think about a support contract with them.

More a personal preference..
I would avoid these "perfect high-end solutions" that can handle 250 VMs but are not allowed to fail. Every solution can and will fail. I remember when the leading web provider in Germany was offline years ago for over a week because they used such a "one large and perfect" solution. (They are called the offline company for years)

I would instead use several, ten or twenty smaller solution, each with a SSD or disk mirror with 1 or 10 Gb connectivity and enoough RAM with the option to add more - in my own config I use napp-in-one where each ESXi has its own independend shared SAN NFS storage and about 10 VMs on them. If one systems fails or a VM is grabbing the whole performance all others are not affected.
