Unable to Access Directory in DEGRADED Pool

[smountcastle]

While I was on vacation for a couple of weeks, I had two drives die and lost power (no UPS). I replaced the failed drives and they started reslivering but appear to have gotten stuck. I left it alone for a few days but since the reslivering wasn't making progress I restarted the server. Now it kernel panics on start up (when mounting the local file systems). Since I was using FreeNAS 8.3.0-RELEASE from a bootable USB drive and there's a newer version available, I downloaded FreeNAS 9.2.1.6 and created a bootable USB stick, imported the ZFS pool and was able to recover some of my data. Unfortunately, the one directory I didn't want to lose is inaccessible, here's the error message I get:

# ls /mnt/Main/Media/Pictures
ls: /mnt/Main/Media/Pictures: Unknown error: 122

If I boot back up with the FreeNAS 8.3.0-RELEASE, I can get in via single user mode but it reports:

# zpool import
pool: Main

state: DEGRADED
status: One or more devices were being resilvered.
action: The pool can be imported despite missing or damaged devices. The
fault tolerance of the pool may be compromised if imported.

Based on that note in the action, I'm afraid to re-import it.

For some background, I setup my RAIDZ-2 all through the Web GUI (following these instructions: http://stevestreza.com/2012/09/30/freenas-build/). When I replaced the failed drives, I used the Web GUI to detach the bad drives and then, after installing the replacements, used the GUI to complete the replacement and initiate reslivering.

Any suggestions for accessing that directory and it's contents would be appreciated, there are some family photos in there that I don't have back ups for (my fault).

Thanks for taking the time to read this and provide assistance,
Sean

To be honest, your options are quite limited. The error about it being mounted on another system is because the pool was never cleanly unmounted. My guess is you actually have another disk(s) failing and you have insufficient redundancy to continue operating the pool since you already have 2 failed disks. This is why we tell people:

1. Don't do RAIDZ1 because if one disk fails you have no additional safety margin
2. If you do have a failed disk you should replace it without delay. More disks will fail as time goes on and you do NOT want to be operating a pool with no additional safety margin

If you really need the photos PM me. I have been known to perform miracles.

I'm confused @cyberjock ...the OP states he has a RAID-Z2. And you're talking about RAID-Z1?

What am I missing?

You are missing the fact that he has 2 disks that are already failed in his RAIDZ2 and I'm suggesting he actually has more. He has PMed me and confirmed that there are more disks that have failed than just 2.
