如何修复 ZFS 创建zpool create出现的invalid vdev specification, xxx is part of active pool 错误

问题背景

在aws实例上运行zpool命令,出现下方错误

zpool create keydb raidz nvme1n1 nvme2n1 nvme3n1
Defaulting to 4K blocksize (ashift=12) for '/dev/nvme1n1'
Defaulting to 4K blocksize (ashift=12) for '/dev/nvme2n1'
Defaulting to 4K blocksize (ashift=12) for '/dev/nvme3n1'
invalid vdev specification
use '-f' to override the following errors:
/dev/nvme1n1 is part of active pool 'keydb'

按照提示执行, 还是不行

root@ip-10-230-3-239:/data# zpool create -f keydb raidz nvme1n1 nvme2n1 nvme3n1
Defaulting to 4K blocksize (ashift=12) for '/dev/nvme1n1'
Defaulting to 4K blocksize (ashift=12) for '/dev/nvme2n1'
Defaulting to 4K blocksize (ashift=12) for '/dev/nvme3n1'
invalid vdev specification
the following errors must be manually repaired:
/dev/nvme1n1 is part of active pool 'keydb'

解决方案

原因是某个volume之前被其他实例用过, 解挂后重新挂到这个实例, 数据不干净导致的.

root@ip-10-230-2-67:~# zpool import
  pool: keydb
    id: 5964941533506504514
 state: ONLINE
status: The pool was last accessed by another system.
action: The pool can be imported using its name or numeric identifier and
	the '-f' flag.
   see: http://www.sun.com/msg/ZFS-8000-EY
config:

	keydb                                                                ONLINE
	  raidz1-0                                                           ONLINE
	    nvme1n1                                                          UNAVAIL  corrupted data
	    disk/by-id/nvme-Amazon_Elastic_Block_Store_vol0fe3cb4f940810f22  ONLINE
	    disk/by-id/nvme-Amazon_Elastic_Block_Store_vol0ef00d1e936279515  ONLINE

有两个办法结局

1. 暴力import

zpool import -f

2. destroy之后, 再创建即可

zpool destroy keydb
zpool create keydb raidz nvme1n1 nvme2n1 nvme3n1
