We currently have a server with 5x3TB disks configured as a RAIDZ:
zpool status pool: raid-5x3 state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM raid-5x3 ONLINE 0 0 0 raidz1 ONLINE 0 0 0 ada1p2 ONLINE 0 0 0 replacing ONLINE 0 0 0 ada2p2 ONLINE 0 0 0 gptid/a767b8ef-1c95-11e2-af4c-f46d049aaeca ONLINE 0 0 0 ada4p2 ONLINE 0 0 0 ada5p2 ONLINE 0 0 0 ada3p2 ONLINE 0 0 0 errors: No known data errors
We want to add 5 more 3TB disks into the same machine, and enlarge the current volume ... is that possible?
I am still confused by the terminology -- vdev/zpool/volume/dataset -- want to make sure I do it right.
As I understand it, I will need to make a new RAIDZ out of the 5 new disks -- is that a vdev? Then add that vdev to the current pool, and we will end up with 10x3TB - 2x3TB = 24TB of storage, where each set of 5 disks can sustain 1 disk failure.
Just not sure what the exact steps are to do this !
Also -- not sure why zpool status still says "replacing" -- it's been like that for several weeks, since I replaced a disk with a hot spare. Is it safe to remove the old disk now?
