I am relatively new to FreeNas. For rirst time I have Alert: CRITICAL: The volume volume_A (ZFS) state is ONLINE: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected.
In View Disk I see my my 2 disks RAID 1 (mirror). What I should do to find out what is wrong and eventually to repair?
