Hi,
my server rebooted after a power outage, and now I am unable to get one of the zfs pools online again.
I went through alot of google searches and tried alot but without success.
So I have 3 pools, rpool, USB_Pool, ZFS_pool
Import doesn't work
zdb -e ZFS_Pool returns
zpool import d /de/disks/by-id sometimes returns output, sometimes doesnt.
So I see that wwn-0x50014ee2b8119cf8 is unavailable, it seems it is totally broken as even lsblk does not recognise it.
however I should be able to get the pool online with one disk unavailable, no? at least in degraded state?
How can I get the zpool online with 1 missing disk?
