Hi, this morning my server crashed, and now my zfs pool says Unmountable: wrong or no file system
I have rebooted to see if the drive was working but its seems the problem is deeper

There's a problem with the NVMe device, make sure it's well seated, or try a different M.2 slot. If the same post is new, do diagnostics before the array starts, while it's hopefully still online.

Reseated and rebooted, now it's online, array autostart disabled and stopped

The device dropped again as soon as Unraid tried to import the pool, it may be failing.

Is there a way to get the file even in read only?

  • Solution

You can try, reboot and then try zpool import -o readonly=on storage
