Protip for the edge case I ran into - if you are running a FreeBSD-based storage OS (i.e. FreeNAS or nas4free) within ESXi, and you're passing a LSI controller to it, you need to add this to /boot/loader.conf:

code:
hw.pci.enable_msi=0
hw.pci.enable_msix=0
Otherwise it won't boot due to mpt driver timeouts. No issues with passing them through to OpenIndiana, Ubuntu, WinXP, or Win7 VMs, though - I was even able to update the firmware on them by directly passing them to a Win7 VM.

Huh that's interesting, what motherboard are you using with that? I don't know how much of a performance difference you get from using legacy interrupts vs. MSIs, might be due to PCI IRQ routing oddities.

Why didn't I think of this? Wasted like 20-30 minutes swapping cards in and out of my desktop while I was trying to figure out if I wanted to do hardware raid on one of the cards or not on my ESXi box. Ended up passing everything through to NAS4Free but still, this would have been easier for flashing purposes

Pretty sure I had to do the same thing on my box for the interrupt timeouts too.

Intel DQ67SWB3. Desktop hardware as an all-in-one server? That's how I roll.

Bizarrely, and probably related to the above timeout issue - if I booted the ESXi box clean from a DOS USB stick to flash, sasflash.exe would puke and give me an error about failing to initialize PAL. There's not much about this error online, except a blurb that says "if you get this error, you need to use another computer to flash your controllers". And yet doing it within a Win7 VM via VT-d worked perfectly.

I had the same issue with flashing some LSI2008 cards. Difference is literally nothing worked, installing OSes in VMs, installing the OS on a physical HDD and turning the server into a giant workstation, Windows, *nix, DOS...

In the end, I remembered that my motherboard (Intel S1200BTL) has an EFI shell, and just maybe there's an EFI version of the flash program?

10 minutes later, both SAS cards flashed.

How long did it take to get there? I'm ashamed to admit around 18 hours worth of waiting for various OSes to install and pulling hardware etc.

I need some advice...

I currently have a RAID 5 array of five 1TB Seagate drives, with a sixth drive I have as a hot spare. The RAID is controlled by an Intel Matrix Storage controller on the motherboard and it has been come really unreliable. It goes in to degradated state and has to be rebuilt about once ever 2 months. It usually doesn't give me any information as to why it failed. It just marks a drive as failed and that's it. If I test the "failed" drive, it almost always comes back clean.

What ever, I am pretty much done with this set up and want to do something new. I need to be able to store at least 3TBs, but anything more than 5TB is probably a waste for me currently.

I am considering the following:

1: replace the five 1TB array with two 3TB drives and set them to RAID 1 in Windows using software, not the motherboard RAID. I don't get as much storage, but I get enough for my needs and it reduces the number of drives which should reduce the chance of drive failures and it gets me off of the motherboard raid. This is the cheapest of my solutions at about $300.

2: Buy a Netgear ReadyNas 4 bay NV+v2 or Ultra 4. These things run between $400 and $600 with out drives. I have a couple of 2 TB drives that are currently in a USB inclosure that I can put in to one of these plus buy another 2 TB drive to get 4TB of storage in RAID 5 mode. Once again, I will have few disk and less of a chance of failure. ReadyNas's also support expanding arrays buy adding disk and you can hang external USB disk off of them so I can kind of easy in to it financially. They also support running apps like SABNZB and Sickbeard on them. These apps are community supported, so I don't know how well they really work. The biggest down side I see to this set up is that these little NASes are kind of expensive for the hardware that is in them. I can build a system with much better specs in a similar form factor for less. Also, as discussed in this thread a lot, RAID 5 is not enough for large disk, so until I added some external disk to back up to, my data would be less protected. I can get started with this option for $600 to $800, and add more drives at a later date.

3: Build a new system and run FreeNAS/NAS4Free/Linux-with-ZFS. This option ends up costing about the same as above, but it gets me more powerful hardware that I can run more apps on. For all of it's strengths, ZFS's biggest downside is that you can not expanded raid arrays with out replacing each of the disk, one by one, with large disk. If build a system for $400 or so, and use three 2TB drives in a RAIDz5 array, plus mirror or copy the data to the two 2TB USB drives I already have, this ends up costing about $700 to $800.

So here are my questions.

First off, does anyone see anything wrong with any thing I said above?

Is anyone using a ReadyNas NV+v2 or Ultra 4? Have any feed back on use them?

Whats the benefit of FreeNAS vs NAS4Free vs ZFS on Linux?

Is there something else I should be considering?

I like option 3 the best, but my NAS is an HP Proliant Microserver N40L. I feel it gives the most control over configuration and what OS I'm using. Before you go to the trouble, you might look at updated firmware for your Sea gate drives. I have four 640GB 7200rpm Seagates in RAID-5 and they used to drop out of the raid pretty often under any high I/O operations which caused a lot of problems. A couple of years ago Seagate released new firmware for them that completely fixed them.

I will look in to the firmware, but I will wait for my array to finish rebuilding. 20 more hours to go.

But to be honest, pretty much all of these drives are out of warranty and I have kind of lost faith in this set up so I think I will probably go ahead and order the system I have spec'ed out.

So, I've got an idea that I would like to bounce off this group just to make sure I'm not crazy. We've got a file server with a pretty standard backup scheme at my office: full backups to tape on the weekends with incremental backups to disk during the week. The tapes are in multiple sets that rotate on and off site. Standard stuff I think. We had an incident recently where a file was deleted by mistake. Unfortunately, it had been mistakenly deleted many weeks ago and we had a copy in backup but only barely. If we hadn't found out about this when we did that file would have eventually been groomed out of our backups and lost permanently.

Rather than re-do our existing backups I'm thinking about dropping something like this Drobo 5n (15 TB) at a different company site and just having our file server do an additional incremental backup to it every night over the company intranet. It would take many years to fill up at that rate and we would then have the option to go digging for old versions of files on the rare occasion we need to. Plus it's yet another backup which never hurts.

Are there any obvious problems with this plan? Thanks in advance.

What is your fileserver running? If, by chance, it's a windows server, shadow volumes may help with the mistakingly deleted file.

I had an HP Mediasmart running Windows Home Server v1, but I came back from out-of-state one day and it was stuck in a reboot-loop. Pulled the drives and I've been without a giant place to store shit for a while. I picked up three 2TB WD Red drives the other day when they were $99 on Amazon; I'm ready to get some network storage going again.

I have a spare case, and I can swap out the PSU; however, I'm somewhat at a loss as to what type of system I should build for a reliable NAS + a few extras. When ordering the not-hard-drive parts, I'll pick up another 2TB Red so I can do RAID6. I know about building a decent desktop and how to piece together a nice HTPC, but I haven't dealt with any NAS stuff that wasn't prebuilt.

What parts should I look into? What OS?

If you're not planning on expanding your storage past 4 drives anytime soon (or ever), the HP N40L/N54L is a great option. Basically pre-built for you, just slap in some extra RAM (8-16GB recommended), an Intel PRO NIC if you want, and a 2GB USB key with FreeNAS/NAS4Free/whatever-other-OS-you-want, and you're off to the races.

If you want something more beefy than that (say, something to do transcoding, or handle a bunch of other jobs than just light file-serving), you'd want to be looking into a low-end i3 (if you don't want VM's), an i5 or one of AMD's offerings (if you do want VM's) and related gear. Most setups like that are a good bit more expensive than the N40L, though, which right now is $270 at NewEgg.

If you want to go really cheap yet still some good power, Intel just recently announced the Celeron G1610 (T-version also available) which costs like 50$, instead of a proper i3. All you miss is HT, RAM clock and some L3 cache. For hardware trans-/encoding you're required to get at least an i3. As for a MB I've recently recommended many ASRock B75 Pro3-M boards, which got loads of ram/sata/pci slots and is light on the wallet.

You could build an AMD zacate based system (dual core 1.6GHz) that support 5x SATA onboard plus has PCIe expansion. I figured it out and with a quality power supply, cheapo case with a 5 in 3 hot swap back plane, 8GB of RAM and the Zacate mobo/CPU you would be looking at just over $300 + the cost of drives. Start with 5, then later on add a sas card and add 8 more SATA drives.

I bought this motherboard
This CPU
and this RAM.

It gives me 6 SATA ports (4x 3Gb and 2x 6Gb), 16GB of RAM (max the mobo supports) and a fairly powerful CPU for a NAS that could be upgraded all the way to Intel's high end quad cores if I ever needed too.

IT ends up costing about $50 more than an AMD zacate, but its a much faster CPU with room to grow if you need it. The only down sides I see is that it will have a higher power draw and will require better cooling. If you want to try to keep it silent, you will probably need to use something other than the stock cooler. I got one of these ZALMAN coolers for my build.

This is all for a Mini-ITX build using this case and this power supply. If you already have a case and PSU you are using, you could be looking at other boards depending on the form factor you have.

HP Microserver can go up to 6 drives. You'd need to go with USB boot though without getting a drive controller card.

If your general needs are fine with the trade-offs of a pre-built that's more cost-effective for simpler needs, then you're probably looking at a Fractal Design or Lian Li case with a possibility of needing to pay for SATA backplanes that can get rather expensive at $80+ each. Mini ITX and even Micro ATX cases tend to go for a bit of a premium compared to a plain box style ATX case. Here's an example of what I mean.

A custom-built machine with the usual sorts of ATX PSUs is about on par efficient with a more dedicated NAS pre-built when you get to somewhere around 7 drives and other tasks because you'll be running at 60w+ continuously. At that point though, I'd start considering the possibility that you just build a slightly beefier desktop that can handle NAS duties on top of whatever else you do because most people tend to want to build separate NASes so they can save some power compared to running a desktop 24/7.

If you go amd with an athlon II you can get something about as powerful but with ECC and vt-d (or rather AMD's equivalent) which is another option depending on what you want. Max power draw will be higher but idle power draw between intel and amd is pretty close.

The Microserver is almost nothing like that Buffalo. The reason people like it is because you're free to use whatever operating system you feel like.

Assuming you don't need more than 5 spinning drives (some people can get 6 in there, but it's a real tight fit and I don't like it), and you're just using it for file sharing, they absolutely are worth looking in to. They're reasonably high quality devices, and perform pretty well, especially considering the price. They've been the darling of this thread for people who just need a decent home file sharing box without too many frills. You can literally be up and running in under an hour from opening the box, and that includes the time it takes to toss in more RAM, load in the HDD's, flash the BIOS (if you want the 5th or 6th drive), and load NAS4Free/FreeNAS on a USB key to boot from. At the end of that hour you'll probably be getting 60+MB/s performance.

Yes, yes you should. Honestly, the only reason to bother with FreeNAS/NAS4Free or the like is to use RAID-Z. If you're going to use hardware RAID or RAID-5, you might as well stick with Linux or Windows Server or something and enjoy the wider variety of other applications you can then run. I.e., I'd love to be able to use uTorrent instead of Transmission, but meh.

FWIW, I've been running ZFS-on-Linux for the last month or so without issue. 8 2TB drives, in a pair of 4 disk RAIDZ1 vdevs in a single pool. I decided against FreeNAS/Nas4Free because I wanted to be able to test VM setups and use the machine for other tasks instead of as a headless server. If you're considering ZFS, it's definitely a solid option. The only glitch I've noticed is kernel updates in Ubuntu will break ZFS, because it's not pilling the headers and source when it updates. As long as you update those and re-add the ZFS modules, it works beautifully.

errors: 13 data errors, use '-v' for a list

It's only 3 files, and they're not all that important. But I've got an extra good disk that I've put in to replace the failed drives but those two keep failing on those three files. So I suspect controler or enclosure, but I'm not sure how to rule out this disks either. I'm not really sure how to go about fixing this.

Is there a guide you used to get it up and working?

I don't think so. Mostly just googlin'. I'm pretty sure there were pages that always popped up during my searches, but I can't recall for sure.

Lowen SoDium posted:

Are you using desktop Ubuntu or Server?

Because I was migrating my server from LVM+mdadm to ZFS, and my server didn't have the physical space to install all my new hard drives, I set up my new ZFS pool on my desktop Ubuntu 12.10, then moved the hard drives into Ubuntu 12.10 Server.

Lowen SoDium posted:

I can switch to FreeNas or Nas4Free as long as the ZFS version is the same between them, right?

I believe so, but I've never done it.

Can anyone recommend a SATA-III PCIe controller card for use with linux software RAID? I have a RocketRaid card that won't work unless the drives are formatted into some proprietary bullshit. The new card shouldn't do that -- the RAID features of the card need to be able to be ignored or disabled. I need hotplug support and four internal SATA ports.

I've been lurking this thread for ages, but decided to go with the ease of a Synology to solve my needs. Unfortunately, I've been having some problems lately with it that I hope some smart goon can help me solve.

I own a DS1812+ and started out with 3 or 4 2TB hard drives in my array. This slowly built up to 6x 2TB hard drives and at that point I needed more storage and added a 3TB HD to the array before realizing I would need two of those to utilize any real space. I decided to take it out and add 2x 2TB to make it a total of 8x 2TB in the array. I ended up having Disk 3 (an older disk) fail the smart test and thus not be able to expand, so I replaced that drive with another 2TB. Following the repair of the array I was still unable to expand it-- it kept saying failed to expand without much more of a log. I decided to reboot the machine, and then all hell broke lose.

Upon reboot, I was greeted with this lovely image of it being unable to connect to the storage manager, and having -1719023912378GB of free space.


SSHing into the disk station, I find the resize2fs is running and destroying the CPU and RAM in the machine.


The weird part is that I can still access the files (albeit slowly) through my mounted folder on my Windows machine... which confuses me a bit. I'm wondering if anyone has experience with anything like this on a Synology product or can perhaps provide any advice? I'm pretty worried here about losing my 9TB volume and would love some reassurance on what the hell is going on. I've posted my problem to the Synology forums, but goon advice is the best advice.

Thanks, one is on the way. Is there any benefit to flashing wih LSI firmware if I just want to use it as an 8-port SATA interface?

e: Looks like I want to use LSI9211-IT or -IR mode to have unconfigured disks: http://blog.laptopvideo2go.com/2011...ata-controller/ & http://www.servethehome.com/ibm-serveraid-m1015-part-4/

I would wait for resize2fs to finish. I'm not sure about the negative space, but resize2fs hasn't let me down yet (on a regular linux machine, not a DiskStation).

e: Looked at the 2nd screenshot... I've never seen more than 1 process for resize2fs when I use it. I'm not sure what I would do in your situation. Killing processes or a hard reboot is probably super dangerous, but waiting would be nerve-wracking too.

e2: Played around resizing an LV and then running a bunch of resize2fs instances simultaneously. All the resize2fs instances say they need to resize the disk, but then I get a bunch of "device busy" messages. I've tried it a few times and so far nothing bad has happened to my volume. Still fscks OK. I think you can wait until the resize finishes and then reboot if resize2fs is still being run over and over again.
