    I could see using the Zotac system if you built a box and then put it in the closet never to use it for more or touch it. But it seems too limited (and very slow) if you want any kind of future-proofing to be able to upgrade with later. I would look at the ASRock system myself. The ASRock can use 8GB of RAM vs. 4GB in the Zotac. Also The ASRock can support USB 3 ports which are useful for external storage. You would probably have to look in to getting something like a PCI-e 1x SATA card for more ports if you wanted to use more than the 4 hard drives it can support with the built-in SATA ports on-board.

    As you noted, the N3700 has issues with running without a monitor.

    Humm. Nope. Since "sdb" is the new drive I just put in, does anything need to be done to it first?

    I have a 8GB DOM to boot with + 5x 2TB RAID 5 array that had a single drive failure. After replacing the burned drive, the RAID array seems to be missing and I can't find it in the menus any longer to remount it. Here are the outputs of the "cat /proc/mdstat", "blkid" and "fdisk -l" commands. Can someone point out what went wrong here and better yet, how to get my array back? I had a drive fail a month ago and replaced that drive no problem. The array rebuilt and was accessible the whole time. This time it's just nowhere to be found?

    I have not had any issues with EXT4 either, yet (EXT4 in 5 x 2TB in RAID 5). Just another point on the side of changing to XFS for future builds especially if someone wants to do a RAID 0 build for speed.

    I suppose the safe answer is to use XFS for now, which isn't a bad thing anyway. Just have to watch to see when there is a good fix for it and I am just going to avoid EXT4 for now.

    Thanks for looking in to it.

    Just thought I would drop a note here. My Netgear R7000 router had a firmware update the past week and now supports USB connected XFS formatted disks instead of ext3 and flaky ext4 drives. I tried a number of different Windows and Linux partitioning utilities but none would make a drive recognized by the Netgear (it is annoyingly picky at recognizing drives). So I gave it a last try and connected the USB hard drives up to my little OMV server and created the XFS formatted drives there. Dismounted them and voila! My Netgear now is happily serving out a network drive formatted with XFS.


    OK, good to know. Have to dump ext4 going forward. So then between JFS and XFS, given my system's relatively low CPU power and 1GB of RAM that can be installed. Which one would be the better choice for making a 16TB+ volume? Or am I asking too much from this equipment really?

    Running OMV 1.14 on my old workhorse Thecus N5200 unit that I retrofitted OMV on to, but it's running an old 32-bit only Celeron 600MHz processor. Now, before I go crazy and do something like buy 5x 6TB hard drives to upgrade it with, what file system limits are there on someone running the 32-bit build? I currently have 5x 1TB drives in RAID 5 and it works just great. Just wondering if there are any gotchas I should know about before looking at upgrading the storage?

    Just wanted to let people know that the old Thecus N5200 5-drive NAS ( not the Pro or XXX version, the original N5200 ) seems to be pretty happy running with OpenMediaVault v1.10. It's a little more involved to get it all running since you have to open the unit up and swap parts and add headers to the motherboard. But it's a really nice little box that I am glad I could get working again. It has an eSATA port, a couple USB 2.0 ports and two gigabit Ethernet ports. The CPU is a Celeron M 600MHz box, so it's not powerful exactly. But it does make it x86 32-bit compatible. Score! If it had been able to do 64-bit that would have been great, but it's too old for that. Now it's running 5x 2TB hard drives in RAID 5 happily. Thanks OpenMediaVault people/community!

    I had two of them to get working again after some drive failures meant that I had to change the hard drives to new ones that have 4K sectors as you can't get the older 512-byte sector models it seems. The old Thecus software started choking regularly on the new hard drives and just wasn't stable any longer. So I started doing some research on replacing the whole NAS that now seemed to be useless. That's how I found OMV. After watching a few YouTube videos I decided to update the OS to something modern that can handle 4K sectors and was still being developed.

    Step 1 - Open the case up and swap the RAM. It came with 256MB of RAM, but I had some spare older DDR2 1GB sticks from an upgrade I did a year or two ago on a desktop.

    Step 2 - Order a new DOM module. The unit had a 128MB DOM unit on it's 44-pin IDE port, but that's just not sufficient if I want to use this thing in the future. After much careful searching I found a good price on an 8GB DOM module. The module in the N5200 was a horizontal DOM, but the case gave me plenty of room to order a vertical DOM unit which was cheaper. DOM modules as I found out are typically used in industrial systems, so they tend to be hard to find and somewhat pricey. I found some 8GB commercial grade DOM modules that were half the price and in Canada already, so no customs charges (win!) to order them. Only problem was I had to wait 5 weeks before I got them <sigh>. I'll link to them below so no one has to try and scour the Internet for them like I did.…html?catid=innolite-ide44

    Step 3 - The N5200 has the place on it's motherboard for a VGA header, Thecus just never installed one on the box to save themselves $0.25 each. As improbable as it sounds, no one has loose VGA headers any longer. It's probably only the most popular video interface in the world for the last 20 years. After much searching locally, I had to order them on-line. It works, but it's not a good fit with the case, so I use an alligator clip to hold the VGA header on to the motherboard long enough to do the installation of OMV then remove it. I'll have to try ordering a slightly different header to see if I can get one that I can one that I can permanently soldier on to the motherboard.…4344-2/A114810-ND/1891556

    Step 4 - Now that I have video working, I use the built-in USB ports to connect a USB keyboard. It has a stock standard AMI type BIOS, so just hit "Del" when it starts up and you get in to BIOS. Go in to the boot settings and set it up to boot from USB CD-ROM first and then the DOM drive. I tried to boot from USB sticks, but the BIOS seems too old to understand how and it always fails. Fortunately I had a old USB CD-ROM drive I could hook-up to it and burned a copy of OMV on to CD to install from. And it works! Went through the setup and about 20 minutes later I was booting in to OMV.

    Of course being a newbie I screwed it up a couple of times. But that's what learning is all about. I can clock it at about 50MB/sec which is 2x as fast as it ever was under the stock software from Thecus. Once I figure it all out I rebuilt the second N5200 I had as well.
