ZFS unable to import pool

[Gena Guchin]

Hello FreeBSD users, 

my appologies for reposting, but I'd really need your help!


I have this huge problem with my ZFS server. I have accidentally formatted one of the drives in exported ZFS pool. and now I can’t import the pool back. this is extremely important pool for me. device that is missing is still attached to the system. Any help would be greatly appreciated.
