ZFS-Pool crashed (Unmountable: Unsupported or no file system)


Recommended Posts

Hi All,

 

this night my zfs-Pool crashed. I had to reboot the server and now the pool can't be mounted (Unmountable: Unsupported or no file system. I attach the diags. May be someone can  help. If I try to import the pool from the command line, I get the following result: 

 

root@UnRaid-Server:/# zpool import cache_docker_vm
cannot import 'cache_docker_vm': I/O error
        Destroy and re-create the pool from
        a backup source.

 

I get same result, if I try to import read only:

 

root@UnRaid-Server:~# zpool import -o readonly=on cache_docker_vm
cannot import 'cache_docker_vm': I/O error
        Destroy and re-create the pool from
        a backup source.

 

What can I do, to at least safe the data? Thanks in advance.

 

Frank
