I got an email alert saying: The volume myvolume (ZFS) state is ONLINE: One or more devices has experienced an error resulting in data corruption. Applications may be affected.

My ZFS pool is two WD Red's, 4TB RAID0. They are brand new (less than 1 week old). After installing them, I copied about 3TB of data via rsync. Last night I initiated a scrub on the volume.

After getting a warning I checked zpool status -v, here are the results:

Code:
 pool: myvolume
state: ONLINE
status: One or more devices has experienced an error resulting in data
    corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
    entire pool from backup.

I was reading up on another thread, where it was advised to run a memory test. I rebooted the system thinking it would be an option in the Grub menu, but it was not. After finishing the reboot, now the device state is unknown, zpool status doesn't not output the volume.

Fortunately my data is backed up on another disk, but right now its my only backup. Not sure what my next steps should be, I guess run that memtest? Does it seem like my disks are bad, or the memory? Or could it have been due to the rsync or scrub?

I think you should put this as a lesson learned, a stripe (RAID0) is not exactly the best idea in the world especially if you have something important to store. Lose one drive in your current configuration and you lose your pool. I'd re-do your pool and create a mirror vdev.

Why is RAID0 bad if I am backing up to another pool? Do you think my disks are bad? I can RMA because they're brand new. The machine is under warranty too if you think the RAM is bad.

EDIT: I forgot to add, yesterday it was reported another drive state is unknown, this is connected via usb. I thought the plug was loose so I secured it, rebooted and the pool came back. I wonder if its related?

Your pool exploded and you have to ask why RAID0 is bad?

You didn't burn-in your system (especially the drives) from what I can see. I guess one of the drive suffers from infant mortality (that's why you want to burn-in the system before putting any real data on it).

Run a long smart test on each drive and repost the output of smartctl -a after the tests are finished (about 10 hours, you can do both drives at the same time).

USB connected drive? that's a genuine very bad idea... there's nothing more unreliable than USB (excepted Realtek NICs maybe... :D)

There's your problem. You have a stripe using a USB drive. Plug the drive in using a SATA connection at best.

Yes, I'm aware its a big no-no, in fact its the reason I spent money upgrading my system over the holidays :p

I'll run the smart tests and post the results, thank you!

I tried this, but the usb enclosure does some kind of hardware encoding on the disk, so I couldn't use it via SATA. My goal was to transfer the data to the two WD Reds, and then wipe the external drive, then use with the system via SATA. A temp solution that's now my only backup... :eek:

Except from Cyberjock's "Slideshow explaining VDev, zpool, ZIL and L2ARC for noobs!":

Using external disks (USB, Firewire, or eSATA) is not recommended.
External disks are prone to accidentally being unplugged by bumping the power or data cable. Plenty of users that swore they would be safe with their server in the basement where its locked and in a corner have still made mistakes and lost data.
Most external disks on a single error of any kind will disconnect and reconnect to the host. This will result in data loss and you may not get any warning that this is going on until it is too late.
USB and Firewire do not allow for proper read/write error detection.
USB and Firewire usually do not allow for proper SMART monitoring, reporting or testing. This removes one of your main methods for identifying disk problems early.
For these reasons, using a laptop is not a good option for FreeNAS because you will have to rely on external disks. They also usually use hardware that isn’t compatible with FreeBSD.
Plenty of users have lost significant amounts of data by using external disks despite these warnings. Don’t be a statistic!
Laptops also make poor choices because quite often the hardware is customized to the point where there are no FreeBSD drivers for the hardware, and you can’t just install a new network card or SATA controller. Even for testing they are pointless as they will not behave properly or effectively to give an accurate assessment of a FreeNAS system.

umm.. this is why things are breaking. ZFS needs direct access to the disks. Stop using usb, stop using enclosures and stop using raid.

The USB drive is not relevant, unless you're saying it has a destructive effect on a totally separate zpool? Regardless, I am attempting to subtract the external drive from my configuration. It is the reason I bought all new equipment. Cyberjock's presentation, which I've read, shows examples of using RAID, so I'm confused as to why everyone is saying RAID is bad, don't use it.

I just ran short smart tests on the two WD reds, and they completed without error. I am running a long test now, I'll post results when they finish. Thanks again for the help, all.

Noone's saying that.

You've striped the 2x4TB drives together, giving you ~8TB of storage, but no redundancy. If one disk fails, all your data is gone.

What's been suggested is to mirror them, which would give you ~4TB of storage. If one of the disk failed, data would still reside on the other disk.

so I'm confused as to why everyone is saying RAID is bad, don't use it.

I guess @SweetAndLow was talking about hardware RAID which is big no-no.

Ah, that makes sense, thanks for clearing it up. Well, one of my drives is definitely F'd. Test has been running for about 5 hours, but I have been notified of an error on one of the disks. Not good, guess I'll have to RMA that one.

Both tests are still running, but ada1 has 30% remaining, where the flagged disk, ada0 has 60% !

As of this morning there are 6 errors, oddly the test now says 90% left... its clear the drive is bad. I will RMA it, one more question though. I bought the two drives together, should I RMA them both? If its a bad batch, the other drive may have errors sooner than later. Then again the damage could have been caused by shipping, or handling somewhere along the line. The second drive shows no errors, here are its results of the smart test:

As of this morning there are 6 errors, oddly the test now says 90% left... its clear the drive is bad. I will RMA it, one more question though. I bought the two drives together, should I RMA them both? If its a bad batch, the other drive may have errors sooner than later. Then again the damage could have been caused by shipping, or handling somewhere along the line. The second drive shows no errors, here are its results of the smart test:


Would be difficult to get an RMA on the second drive since it has no errors. IMO, if it passes the testing I would say keep it since it can be classified as a "known good" drive then. There may always be the chance that a new drive has "infant mortality" or could be damaged in shipping as well. P.S., it pays to have extra spare parts as well.
