Booting FreeNAS: zpool import causes panic

[intelligence]

Follow up to my previous thread here: https://www.ixsystems.com/community...-hba-–-supermicro-x11sch-f-lsi-9207-8i.86231/

I've since replaced the HBA with a new one and still facing the same issue, when FreeNAS tries to import the pool during boot it'll crash.

zpool status + zpool import gives me this:

Following the advice from a thread on Reddit I tried:

Code:

sysctl vfs.zfs.recover=1
sysctl vfs.zfs.debug=1
zpool import -Ff Storage

Which renders:

Anything I can do at this point, or is my data gone?

Looks like the errors start happening after attaching gptid/058360d8-3123-11e8-adc8-d0509946c62a. What happens if you remove this disk before starting the import?

Different output, but same result :(

OK, you've got a bad disk somewhere in the pool. Reconnect that drive, and try disconnecting each of the remaining drives, except for ada0-3, and reimporting each time.

Started that process now, not sure which are ada0–3 so I'm just pulling one at a time.

Here's some video output from latest try. Anything specific I should look for?

I have now tried testing importing the pool with one drive disconnected, cycling through all 10 of them. I get the same error every time.

Working theory is that data was corrupted when old system suffered power loss or similar (it would die randomly, before dying altogether). Can anyone confirm if this seems plausible with the error ouput? And if any thing can be done at this point to recover.

Maybe the corrupt BLKPTR is on your boot pool. Try reinstalling to a new disk, and then try the import again.
