Hi _Gea ... Any ideas why I wouldn't be able to set the admin/operator passwords for napp-it? I'm running Ubuntu 14.04 (x64) and I've configured everything as per the guide on the website. I've entered new passwords under home > about > settings, but when I logout or restart napp-it...

Are there any more updates on peoples experiences with these AC units? I've just received two of them to run as trial units for a 60+ AP deployment, and I'm just trying to gather up as much information as I possibly can.

I can see how a dodgy backplane might be able to damage a disk (as well as the backplane itself), but I'm struggling to see how any of your other components could have been damaged? When you say that the system "does not work", what exactly do you mean by that? Does it power actually on at...

If they're mirrored, then I probably wouldn't be too worried about getting the data off the array. Order yourself a new drive, and just swap it out ASAP. In the meantime, run a scrub on the pool and see what it reports.

At the risk of going off-topic, I'd be very interested to know what you're using to handle the replication?

Unless I'm misunderstanding what you're trying to accomplish, wouldn't the simplest solution be to simply run you NFS / ISCSI data in a separate IP range and/or VLAN ID? That's a pretty standard best practice approach ...

I've been umming and ahhing about the Supermicro A1SAM-2750F for a while now, but in terms of "bang for buck" (especially considering what I actually need from them), these ASRock boards look like pretty clear winners to me. Definitely planning on grabbing a couple of C2550d4i boards once I'm...

There really is no ideal solution to this problem, but you might want to look at zfs copies as a potential option. https://blogs.oracle.com/relling/entry/zfs_copies_and_data_protection Basically, setup your pool as raidz (in order to maximise available space), but then you can specify...

I'm not sure whether it will actually have any impact on the problems you're having, but I have noticed that LSI have just recently released new firmware/driver updates for those cards which might be worth looking into...

You'd be silly to waste all that space for only a single drive though, especially when you can pickup enclosures that will let you run 4-6 drives in the same amount of space. http://www.icydock.com/goods_cat.php?id=48 Yes ... there's cheaper options out there, but these are my favourite in...

Hi guys, I'm working on a new ZFS server at the moment, and I'm at the stage now of trying to figure out a decent snapshot schedule/strategy. Now ... before anyone gets up in arms, I know that snapshots DON'T replace backups, and we're already planning on replicating the data onto another...

Indeed. I'm half way through migrating all my servers at home from Solaris to OI.

Is that only because he's having problems, or do you prefer NFS in general?

Thanks guys ... it does indeed look like you've nailed it, and I've just learned something in the process as well! ;) Much appreciated! --David

Did that ... the only difference is volblocksize = 8K (instead of 512 on the Napp-it created volume). I can't see how that would be related to the problem at all though?

oops ... double post

PROGRESS! I still don't understand exactly what's going on, but I've now narrowed down the problem as something to do with the Napp-it UI (which is what I've been using to create/manage my volumes). I ssh'd into the box and created a volume straight from the command line: # zfs create -s...

OK ... So the problem looks like it's actually NOT thin provisioning, but rather something weird which seems to be happening with volumes in general. I just created a new volume without thin provisioning, and I'm still seeing exactly the same thing happening. I created a 5GB volume, and...

Just to try and make sure that I wasn't going crazy, I created another LUN (same as above) and copied some data onto it. The same thing happened again! Then I created a simple file based LUN, copied over the same set of data again, and this time it showed the correct amount of space used...

I’m working on getting a new ZFS box up and running, but I’ve come across some weird behaviour that I’m struggling to try and understand. 1) Create a 2TB volume - thin provisioned. 2) Create an iSCSI LUN within the volume 3) Mount the LUN on the client machine, and copy some data. I’ve...

Otherwise, if you're not happy about losing 2 disks to redundancy by using RAID-Z2, I'd also consider setting up 5 x HD204UI in RAID-Z, then your remaining 5 disks in another RAID-Z. That gives you 16TB of usable space right off the bat, without having to worry about buying any extra drives...

I think that you might be getting your concept of vdevs a little bit mixed up there. You can add as many VDEVs to a pool as you'd like, and ZFS just combines it all into a single consolidated set of storage. IE - You don't have to worry about spreading data across the different VDEVs...

YES ... and frankly, that's the biggest reason why I'd prefer using mirrored pairs for something like ESX storage. There's a great blog post by Constantin Gonzalez which explains it all really well - http://constantin.glez.de/blog/2010/01/home-server-raid-greed-and-why-mirroring-still-best...

What do you mean exactly when you say that they wouldn't plug in? The caddies are supposed to fit 2.5" drives as well, so there's no reason why you shouldn't be able to use them. Are you sure that you're installing the drives into the caddy correctly?

You do realise that WD own Hitachi now, so I'm not sure why this is any sort of a surprise to you?

Keep an eye out for cheap IBM M1015 cards being sold on eBay. They're your best bet at the moment.

You don't need anything special at all. The PSU will have a cable/connection for the power, and either your motherboard and/or hard drive will (more than likely) have a cable for the data connection. EDIT ... And if you don't have one for any reason, they're 99 cents on eBay! ;)

In which case I'd consider the Supermicro X9SCM board to be better in just about every respect, including price. http://www.supermicro.com/products/motherboard/Xeon/C202_C204/X9SCM.cfm http://www.newegg.com/Product/Product.aspx?Item=N82E16813182254

Toshiba 3.5" drives are basically just re-badged Hitachi disks. Hitachi were taken over by WD in 2011, but they had to resell the 3.5" division to Toshiba in order to avoid problems with various competition regulators around the world...

I've found that ZFS can be extremely temperamental regarding the state of snapshots between different systems. Personally, I avoid having to mark the destination source as read only (because even doing that still gave me issues), and just use "zfs recv -F" on the receiving server, which simply...

Just a quick question please guys ... I've just received a Supermicro X9DRD-7LN4F motherboard, and I'm wanting to flash the onboard SAS controller [which is listed as LSI 2308] to IT mode. There's no downloads on the LSI website listed specifically for the 2308 controller, but there's firmware...

Hi guys ... I'm having a problem managing automatic snapshots through the napp-it UI. Jobs > snap > create autosnap job I'm configuring everything as I'd like it to be and when I hit the submit button the page reloads, but it's not creating/displaying the job in the task list at the top of...

Hi _Gea ... I'm currently evaluating a new SE11 / Napp-it box here at work, and I've just run into a bug trying to join it to an AD domain. Every time I tried to join it, I received the "failed to find any domain controllers" error message. I spent lots of time trying to troubleshoot...

Thanks Blue Fox ... that seems to have pointed me in the right direction. I understand why Supermicro might not produce any heatsinks directly, but I was having a hard time finding anyone else that made compatible units. Obviously never heard of Dynatron! ;)

So ... I bought this board a little while ago, and it came with the CPU backplate [BKT-0028L] already attached. I've had a look and there's absolutely no way that you're able to remove it, so I knew that I wouldn't be able to use the stock Intel CPU [which uses the push pin locking mechanism]...

Yeah ... Again ... I've double checked that all the drives are showing up correctly in the 'disks' tab [which they are], but for some reason it's just not letting me load the pool.

... and I'm freaking out. Here's the story. I had a pool running quite happily under FreeBSD/ZFSGuru, but curiosity got the better of me and I wanted to try exporting it onto a new box that I'd setup running Solaris/napp-it. I'd made a couple of small pools on the ZFSGuru box using some...

I've just added 12TB [formatted capacity] to my storage server about a week before the price jump. I'm using right around 1TB a month though, so even with that in mind I'll probably still need to add some more disks by this time next year.
