Had this monitor since the 4th Nov and thought I'd post some thoughts. I'm using it with a Windows laptop and a Windows desktop. Laptop plugged in via TB4 and the desktop using DP and USB3.2. The display itself is lovely and I'm very happy with the extra real estate. I came from a 3440x1440...

Thanks. On the PLP point, if you have a UPS that can shutdown the server, is it as important? The cost of those SAS SSDs is far too high though. They seem to be >3X the cost of a consumer drive and I'm not sure I'm going to get anywhere near the endurance limits.

Hey, just about to buy some hardware for my next machine and wanted some advice on where to spend the cash. I'm building an all in one and wondering whether it's worth just getting more RAM or spending on an NVMe array for VM storage. I have spinning rust as my main backup/storage and want to...

Great, couldn't see the wood for the trees there. So that seems to work nicely and I'm now getting the snapshot created and backed up. At the moment my esxi VM store is a basic pool of 1 SSD. If I want to change that in the future, is the process I need to follow: delete the current pool of...

Hi, I've been trying to understand the ESXi hot snap feature of napp-it and now have it working after some experimenting. What I'd like to do now is use zfs send to back up those snapshots but I can't see an option in the napp-it UI. Is there one or do I need to script this myself?

OK, great. Understood.

OK, thanks. So there's a lot of badly worded descriptions out there then! But that really doesn't change my question. The Optane SLOG is removing the write latency associated with the ZIL so why is my randomwrite perfromance not as good? What is it about FileBench's randomwrite.f test that...

Every description I've read of the ZIL says it's a write cache. For example, this quote from ixsystems: "When synchronous writes are requested, the ZIL is the short-term place on disk where the data lands prior to being formally spread across the pool for long-term storage at the configured...

Perhaps I'm missing something here but isn't the point of using Optane to decouple the slow spinny things behind it from the write data. I've got a 20G write cache so shouldn't that be able to soak up over 20G of writes before it fills and back pressures the incoming stream?

Yes, a 3 way mirror. I was assuming these benchmarks would be small enough to be soaked up by the Optane. So am I seeing a negative effect from the underlying vdev?

Hi, I've got an AiO setup with an Optane 900P and I'd like some advice on the best setup as I'm not getting the same performance as detailed in Gea's optane_slog_pool_performance.pdf. I've got a Supermicro X9SCL with a E3-1240 V2. My OmniOS VM has 4 vCPUs, 16GB of RAM and an LSI2008 passed...

Thanks Gea, can anyone point me at some reading on how to benchmark storage and/or applications? I guess a good starting point would be to benchmark our current machine and workflows. We're running on CentOS if that makes a difference.

Hi there, looking for some system advice. I'm looking at setting up some shared storage for a mini cluster and wondered if I can do that with Napp-IT. We're going to have 3-4 compute nodes running a mixture of EDA tools and numerical simulators and I'm trying to understand how to implement...

Origin_Unknown, I have an Intel SAS8UC8i that was flashed with the LSI IT firmware. I was having no speed issues with a 6 drive raid-z2 during my initial testing. Can't remember the numbers but well over 100MB/s. As for my WD Red drives, they checked out fine during my stress testing and...

Thanks for the simple maths lesson - don't know why I didn't do it myself now. :) As for the -c switch, I found a post somewhere on the web that said the larger the number of blocks you run at once the faster it will run. I initially tried to use 4GB per instance but that segfaulted so I...

Hi there, I picked up a couple of these drives last week and have been stress testing them before I stick them in a NAS. I've run DBAN and am currently running a 4 pass badblocks. However, from the threads I've read so far I wasn't expecting it to take this long. Current elapsed time on...

Just getting back to testing my drives after noticing SMART errors. Does anyone have any suggestions for tools to use to test HDD's? I'm using Samsung's ES-Tool to perform a low level format but it isn't finding any problems.

OK, thanks. Something else to try. The case is a Fractal Design Define R3 and the drives are all mounted on the default trays with rubber grommets. The drives are all upside down though for cabling purposes - HDD's can cope with any orientation though can't they? What about SFF-SATA...

Thanks a lot for this and you are correct, I don't know much about SMART data, mostly because I've never been able to find any decent documentation. Is there any? My currently plan of attack is to use Samsung's ES-tool to investigate each drive using the built in controller on the...

Standard all-in-one: X9SCL, E31230, 16GB RAM, Intel SASUC8i, ESXi 5.0, OI_151a.

Hi there, I've been trying to go through pulling a disk from my array and making sure I know how to add a new drive and have it resilver. In the process I've been looking at my SMART data and notice that one of the drives is marked as failed. I'm using Samsung HD204UI's and the raw read...

To close my own thread...I finally found the answer here: http://www.justlinux.com/nhf/Filesystems/Mounting_smbfs_Shares_Permanently.html When you connect to an SMB share from Linux only the local root user is given write permission. It doesn't matter what the ACL's of the share are or the...

Yes I have gone through what I think is the flow. I can successfully connect from OS X so it looks like it works. But as previously stated, it doesn't work from Ubuntu.

I appreciate that, but was I wrong in assuming that OS X and Ubuntu should behave in the same way? My aim is to connect to the SMB share via Ubuntu and not have to run everything as root. It works correctly on OS X.

Just to give some more information. If I connect from OS X I am prompted for a username and password. When I list the share I see the owner:group as sjalloq:staff. I cannot mount from Ubuntu unless I specify a username but it doesn't care if I specify a password or not. Once mounted all...

Hi there, I'm trying to go through and set up SMB sharing but am having a problem mounting from Ubuntu. So far I've followed the instructions and can connect to the SMB share from OS X. All the permissions are set up and I can create and edit files and they gain the owner and group attributes...

How do you specify the username/pw when mounting on NFS?

Now that I can actually mount my NFS share I have another question regarding user names and permissions. I'm accessing my shares from OS X and Linux hosts via NFS and AFP. I will have futher clients, probably Linux, running under ESXi and all will use the same username of 'sjalloq'...

Hmmm, I was about to argue that your steps don't work but I've just tried again and they do. I created a ZFS folder using napp-it, turned on NFS sharing and left all the defaults. I tried that multiple times over this last week and nothing worked! Perhaps I've now restarted the relevant...

OK, finally solved it. Thanks to the lovely people on the OI IRC channel. This post details what is needed: http://mordtech.com/2008/12/11/leveraging-zfs-nfs-for-esxi/ I had to set the sharenfs as follows: $ sudo zfs set sharenfs=root=@192.168.1.144 This isn't detailed anywhere in the...

Here are my current share settings: sjalloq@openindiana:~$ zfs get sharenfs tank/nfs NAME PROPERTY VALUE SOURCE tank/nfs sharenfs rw=@192.168.1.0/24,root=@192.168.1.144 local sjalloq@openindiana:~$ ls -al /tank total 13 drwxr-xr-x+ 4 root root...

Thanks Dan, I already have the permissions set up. However, I seem to get different error messages when I retry creating the datastore. This time I got: Call "HostDatastoreSystem.CreateNasDatastore" for object "ha-datastoresystem" on ESXi "192.168.1.144" failed. NFS mount...

Continuing my NFS pain I posted on the VMWare forum for some help. The first question that came back was to make sure I'm using NFSv3 and the no_root_squash option. Having done some research it seems OI defaults to NFSv4 and I can't find the Solaris equivalent of no_root_squash. Could...

Thanks but that article is for esxi 4.1 and previous versions. Not only does it not seem to suggest anything useful but esxcfg-firewall doesn't exist any more.

Very good suggestion! I'm no expert (or even capable noob) with NFS so I followed the guide on the Ubuntu help pages and, once I had changed the permissions on my export, I could mount it inside of ESXi. So this suggests something with my OI installation. Next steps? [EDIT: actually, I can...

Still can't get ESXi to mount a datastore via NFS. I've managed to turn on the console and have got the following out of the vmkernel.log - does it help anyone identify what might be wrong? 2011-12-07T23:46:49.088Z cpu6:2854)NFS: 157: Command: (mount) Server: (192.168.1.113) IP...

If I search for the error here I get nothing. I found the following article online but having added the VMKernal Port I still get the same behaviour...

Heh, still can't create an NFS datastore in ESXi though. :( Getting this error from within ESXi: Call "HostDatastoreSystem.CreateNasDatastore" for object "ha-datastoresystem" on ESXi "192.168.1.144" failed. Operation failed, diagnostics report: Sysinfo error on operation returned status...

:rolleyes: I thought it was installed by default, thanks. So I can mount the folder now and having change the permissions I can access the folder. What sort of performance should I expect when using NFS? Should I be able to max out a Gb ethernet link? What about AFP - is that much slower?

You mean under the Services->NFS tab? Yes, it says 'online' and I've tried restarting it a number of times. The text on the page also says that if you nfs-share a folder the nfs-service is started automatically. As an aside, and to rule out a few things, should it be possible to mount the...
