無法在 iSCSI 多路徑驅動器上創建 zfs 池

  • September 20, 2013

我在 iSCSI SAN 上有一個磁碟,我通過多路徑將它安裝在我的伺服器上。當我執行命令來創建 zfs 池時

zpool create -f zfs-data /dev/sdc

或者

zpool create -f zfs-data /dev/sdd  (as the disk is mounted on both sdc and sdd)

我得到錯誤:

cannot open '/dev/sdc1': Device or resource busy
cannot create 'zfs-data': one or more vdevs refer to the same device, or one of
the devices is part of an active md or lvm device

fdisk -l 給出以下輸出:

Disk /dev/mapper/eql-0-8a0906-f10764e0b-590d2ef939e523ac_b: 107.4 GB, 107379425280 bytes

不能在多路徑設備上創建 ZFS 池?

您可能會獲得 sdc 和 sdd,但您需要使用通過它們創建的多路徑設備。‘multipath -ll’ 的輸出是什麼?例如,我在這裡有四個路徑:

dbslave2-mysql (36090a028c039386000104572042da1b0) dm-3 EQLOGIC,100E-00
size=550G features='1 queue_if_no_path' hwhandler='0' wp=rw
-+- policy='round-robin 0' prio=1 status=active
|- 6:0:0:0 sdf 8:80 active ready running
|- 9:0:0:0 sde 8:64 active ready running
|- 8:0:0:0 sdc 8:32 active ready running
`- 7:0:0:0 sdd 8:48 active ready running`

所以我使用 /dev/mapper/dbslave2-mysql,而不是 sdc、sdd、sde 或 sdf。在您的情況下,您似乎會在 zpool 創建命令中使用 /dev/mapper/eql-0-8a0906-f10764e0b-590d2ef939e523ac_b 。
