I was just playing around with a test ZFS system and was running through replacing a bad drive and I forgot to issue a ‘zpool offline’ command. Everything seemed to go ok anyway. The system started resilvering, etc. When is ‘zpool required’? Under what conditions can I omit it?
Is there a dedicated mailing list for ZFS user questions?
