RAIDZ1 - Unavail + Offline

Hello guys. I have a 6 drive RAIDZ-1 setup. Was replacing one drive (probably gptid/47af1739) and after booting, pool was OFFLINE/Data not available.

A ssh-ed into my server and it shows that gptid/4766b1cd is offline ?!

root@truenas[~]# zpool import
pool: Kukoleca
id: 9915218132335776628
state: UNAVAIL
status: One or more devices are missing from the system.
action: The pool cannot be imported. Attach the missing
devices and try again.

config:

How can I get it online and import the pool? Any help? Much appreciated. Thank you all in advance.

Unfortunately the error message “insufficient replicas” usually means three is not enough information for the ZFS pool to be mounted. You can try to force the import with:
zpool import Kukoleca -f
But if that does not work then it is time to restore from backups.
