展开zpool

Question

你好，我想展开我的vdev，我很困惑我需要什么命令才能这样做。这是我有的东西

  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命令似乎只用于创建新的vdevs，例如raidz2-1，附加命令似乎只用于镜像。

提前谢谢。

     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.

使用谷歌-在zfs中目前还没有这样的功能。
