I have an OpenSolaris server with a zpool
backupz comprised of four SCSI drives:
-bash-3.2# zpool status backupz pool: backupz state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM backupz ONLINE 0 0 0 raidz1 ONLINE 0 0 0 c7t0d0 ONLINE 0 0 0 c7t1d0 ONLINE 0 0 0 c7t2d0 ONLINE 0 0 0 c7t3d0 ONLINE 0 0 0 errors: No known data errors
I want to add a fifth drive... but
zpool add backupz raidz c7t4d0 isn't working...
-bash-3.2# zpool add backupz raidz c7t4d0 invalid vdev specification: raidz requires at least 2 devices
Can I not have a raidz config with 5 devices? Do I have to add two devices at once? or am I doing something incorrect altogether here?
