Good evening, all: When I setup my current box that’s doing ‘real’ work using SmartOS, I only had four old 1G SATA disks setup thusly:
[root@headnode ~]# zpool list -v
NAME SIZE ALLOC FREE EXPANDSZ CAP DEDUP HEALTH
ALTROOT
zones 3.62T 479G 3.16T - 12% 1.00x ONLINE
-
raidz1 3.62T 479G 3.16T -
c0t5000CCA375D44795d0 - - - -
c0t5000CCA375D4B7D3d0 - - - -
c0t5000CCA375D4B7ECd0 - - - -
c0t5000CCA375D5D4A7d0 - - - -
[root@headnode ~]#
I’m probably going to pick up a bunch of SAS drives soon (whatever Keith says
is the right thing to use in the manufacturing data, naturally :)) and
(hopefully) add new mirror zvols
(a la zpool add zones mirror newDisk1 newDisk2 run n times)
That brings up two questions. Firstly, will that procedure work? Secondly, if
I want to vacate the existing raidz1 zvol so that I can remove those four disks
and replace them with a pair of mirror vdevs, is there a supported way to do
that online? If I can avoid downtime, that’d be most awesome.
