cannot import volume - I/O error

[Jusso]

Hi All,

Needing help please to import my volume back.
I have RaidZ 3x3tb setup that the volume went to a state of being "unknown available space" so i decided to detach the volume to re import it, without success. It seemed to of gone down while transferring data to it.

Any Ideas? The 3 HDDs are new, not even a month old. :(

Please post full hardware specs and ZRAID type.

 

[sretalla]

also post the output of zpool import

Maybe we can see something else there to explain why that specific pool can't be seen.

See what it says if you try zpool import -Ffn Main.

Hey unfortunately nothing.

If I import through the GUI this is the error

Nothing at all?

Sounds like your metadata is corrupt. You can try mounting it as read-only by running zpool import -o readonly=on -fNR /mnt <pool>.

Looks like your pool is toast. :(

Time to restore from backups.
