I want to a replace a disk in my Zpool ( a 7 disk RAIDZ1 ) i already have an 8th disk as marked “spare” in the Pool.
the disk i want to remove is part of the active array. there’s nothing wrong with it, it’s just a 5400RPM drive and i want to replace it with the same capacity disk but a 7200RP model to match the rest of my disks.
How should i go about this?
Should i mark the disk i want to remove as “offline” or “replace”. Does the pool “spare” automatically take its place if i do either of these things ? or do i have to do some sort of manual intervention
( do spares only kick in in the event of a disk failure?)
and does that initiate a resilver or does that have to be manually set away?
finally when i pull the disk i want, and put a new one in its place, i presume i then have to add that to the the pool as a new “spare”?
