can't import ZFS pool after power outage (loss)

[madiseh]

Hello Guys
I need help.
After power outage (loss) when I start FreeNAS on ESXi (VirtualMachine), one ZFS pool is not loaded.



After detaching the pool I cannot attach the pool again.


After that I SSH to FreeNAS and run this code:
--nas1 is my pool

Code:

zpool import -f Nas1 

Unfortunately I do not have any backup from my data and very important data.

if possible please help.
sincerely yours

I was helping troubleshoot someone with a similar error. Hopefully this thread helps: https://forums.freenas.org/index.php?threads/current-interruption-volume-does-not-mount-help.61553/

Unfortunately, in the end, we were not able to recover his data. Please don't take this as me rubbing salt in the wound, but even the best, most robust systems are not perfect, and backups are a critical piece of any storage solution. I hope that you take this to heart, and if you end up losing data, this will be the last time you have to suffer through it.

What is the output of zpool import

Did you use a virtual disk or direct disk passthrough for your FreeNAS zpool from ESXI?

Dear nick
thank you for your quick response. I hope so for recovery my data;)
It's my fault. I get serious about your advice, and absolutely take a backup from my very very verimportant data.

Dear rs225
Thank you for your time and kindness:)

Dear scrappy
Thank you for your attention:)
It's a virtual disk.

Dear scrappy
Thank you for your attention:)
It's a virtual disk.

It is recommended to always use hardware disk passthrough for zfs unless you are using virtual disks for testing purposes only. I've read several posts like yours where the zpool gets corrupted resulting in data loss after the host machine loses power, or the system crashes etc.

After some trying I received this error. My data is here but I cannot access it.
For example how can I access Nas1/Personal (dataset).
If possible please help me...
Really need to help.
Thanks

You will need to post the output of zdb -l -u /dev/gptid/xxxxx (your disks ID), and it will need to be pasted in a CODE block, not as a picture.

It doesn't look good. Has any one ever seen a pool brought back from the I/O error state?

Thanks for your reply. I hope that with your reply I give good result :)

It looks like spacemap corruption. Importing the pool read-only might allow you to read everything off the pool.

 

[rs225]

It looks like some write caching was going on, so your metadata is scrambled.

I've never seen it work, but you can try each of these to see if any work or give an error beside "one or more devices is currently unavailable".

Code:

zpool import -o readonly=on -T 3769617 Nas1
zpool import -o readonly=on -T 3769616 Nas1
zpool import -o readonly=on -T 3769615 Nas1
