Restarted, lost volume

[streetlamp]

Hi all, linux/freeNAS noob here

Recently got a freeNAS setup and had it running strong for about a month, had severe storm warnings the other night and since I don't have a UPS I decided to shutdown the system incase we lost power. Restarted the next day to find an error and unable to access the volume, unfortunately I have lost the error however.

At this point I could still see the volume but I had read a few other forum posts about exporting and reimporting the volume. So I exported through the GUI and now can't reimport or do anything.

Some console outputs below, any help is extremely grateful

Looks to be your problem right there. This is a single stripe ZFS pool on hardware RAID5?

Code:

zpool import

zdb -l /dev/raid5/NASty5p2

Or whatever the actual path is to the RAID5 disk.

You also forgot your FreeNAS version.

 

[streetlamp]

Sorry, I just got back around to trying to figure this out.
This is FreeNAS 8.3.1
zpool import does nothing and zpool status shows no pools being available.

I used

Code:

gpart recover raid5/NASty5

Which got rid of the CORRUPT error

This wasn't the best idea to run this early.

zdb seems to see something

What's the actual pool configuration? Correct me if I'm wrong, but you appear to have 7 500 GB drives in a RAID5 configuration. On which there is a 2GB swap partition and a 463 GB ZFS partition, hmm. That's a bit odd now that I think about it. Is the RAID5 configuration something old? The zdb output appears to indicate it's actually using the individual disks or rather the GPT partitions on them.

However, this is all I get from zdb -l /dev/da0 to da6

Not what I asked for. However, if there is old GRAID metadata on the disks that would stop ZFS from being able to import the disks as GRAID grabs them first. If that's the case then see this thread.

 

[streetlamp]

The pool configuration is in Raid-z. And its all fresh, disks were all wiped and pooled when I bought this system. The pool is ~2.7tb, 463gb is what is currently full.
