我有一台zSolaris backupz
由四个SCSI驱动器组成的OpenSolaris服务器:
-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
我想添加第五个驱动器...但是zpool add backupz raidz c7t4d0
不起作用...
-bash-3.2# zpool add backupz raidz c7t4d0
invalid vdev specification: raidz requires at least 2 devices
我不能使用5台设备进行raidz配置吗?我必须一次添加两个设备吗?还是我在这里完全做错了什么?
