$ sudo zpool status -v pool: lxd state: ONLINE status: One or more devices has experienced an error resulting in data corruption. Applications may be affected. action: Restore the file in question if possible. Otherwise restore the entire pool from backup. see: http://zfsonlinux.org/msg/ZFS-8000-8A scan: scrub repaired 0B in 9h3m with 1 errors on Sun Apr 14 09:27:53 2024 config:

$ sudo umount /mnt
此时查看zpool状态报错信息如下：
$ sudo zpool status -v pool: lxd state: ONLINE status: One or more devices has experienced an error resulting in data corruption. Applications may be affected. action: Restore the file in question if possible. Otherwise restore the entire pool from backup. see: http://zfsonlinux.org/msg/ZFS-8000-8A scan: scrub repaired 0B in 8h50m with 1 errors on Sat Apr 20 04:36:35 2024 config:

再次执行sudo zpool scrub：
$ sudo zpool status -v pool: lxd state: ONLINE status: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected. action: Determine if the device needs to be replaced, and clear the errors using 'zpool clear' or replace the device with 'zpool replace'. see: http://zfsonlinux.org/msg/ZFS-8000-9P scan: scrub repaired 0B in 9h20m with 0 errors on Sat Apr 20 19:52:37 2024 config:

显示错误貌似消失了，但是还是让执行sudo zpool clear：
$ sudo zpool status -v pool: lxd state: ONLINE scan: scrub repaired 0B in 9h17m with 0 errors on Sun Apr 21 05:41:04 2024 config:
NAME STATE READ WRITE CKSUM lxd ONLINE 0 0 0 /var/snap/lxd/common/lxd/disks/lxd.img ONLINE 0 0 0
errors: No known data errors
至此，LXD使用的ZFS文件系统已经没有问题了，但是执行sudo lxc list还是会报错：
Error: LXD unix socket "/var/snap/lxd/common/lxd/unix.socket" not accessible: Get "http://unix.socket/1.0": dial unix /var/snap/lxd/common/lxd/unix.socket: connect: resource temporarily unavailable
查看lxd的调试信息如下：
