您好，我正在寻找扩展我的 vdev，但我对需要什么命令来执行此操作感到困惑。这是我所拥有的
pool: DATA01
state: ONLINE
scan: scrub repaired 0B in 0 days 07:43:11 with 0 errors on Sun Aug 14 08:07:15 2022
config:
NAME STATE READ WRITE CKSUM
DATA01 ONLINE 0 0 0
raidz2-0 ONLINE 0 0 0
/dev/sda ONLINE 0 0 0
/dev/sdb ONLINE 0 0 0
/dev/sdc ONLINE 0 0 0
这就是我想要的（一个额外的驱动器）。
pool: DATA01
state: ONLINE
scan: scrub repaired 0B in 0 days 07:43:11 with 0 errors on Sun Aug 14 08:07:15 2022
config:
NAME STATE READ WRITE CKSUM
DATA01 ONLINE 0 0 0
raidz2-0 ONLINE 0 0 0
/dev/sda ONLINE 0 0 0
/dev/sdb ONLINE 0 0 0
/dev/sdc ONLINE 0 0 0
/dev/sdd ONLINE 0 0 0
add 命令似乎仅用于创建新的 vdev，例如 raidz2-1，而 Attach 命令似乎仅用于镜像。
提前致谢。
zpool add [-fgLnP] [-o property=value] pool vdev...
Adds the specified virtual devices to the given pool. The vdev specification is described in the Virtual Devices section. The behavior of the -f option, and the de‐
vice checks performed are described in the zpool create subcommand.
zpool attach [-f] [-o property=value] pool device new_device
Attaches new_device to the existing device. The existing device cannot be part of a raidz configuration. If device is not currently part of a mirrored configuration,
device automatically transforms into a two-way mirror of device and new_device. If device is part of a two-way mirror, attaching new_device creates a three-way mir‐
ror, and so on. In either case, new_device begins to resilver immediately.
