目前我有一个 4TB 的池,其中有两个条带驱动器:
# zpool status
pool: lxd
state: ONLINE
status: Some supported features are not enabled on the pool. The pool can
still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
the pool may no longer be accessible by software that does not support
the features. See zpool-features(5) for details.

config:

我有一个 4TB 的驱动器,我想将此池镜像到该驱动器,以增加冗余。我很难弄清楚这是否可行。我尝试了附加命令:
# zpool attach lxd lxd /dev/disk/by-id/wwn-0x5002538f4361edfb
cannot attach /dev/disk/by-id/wwn-0x5002538f4361edfb to lxd: no such device in pool
但我不确定我是否遇到了错误,或者这不是解决办法(甚至不可能)。谢谢!

不,您不能以这种方式嵌套 vdev。
为了获得更好的冗余,而无需重新进行池配置和/或引入lvm
或md
连接较小的驱动器,最好的方法是send/recv
定期将所有数据复制到较大的驱动器。
