我有以下 lvm 配置。

Hard Disk: /dev/sdb  (Size 10 GB)
VG: vg_root on /dev/sdb
THIN_POOL thin_pool occupying the whole physical extent
lvcreate -y --extents 100%free --thin vg_root/thin_pool

Thin volume on the thin pool
lvcreate --name lv_1 --virtualsize 1GB --thinpool vg_root/thin_pool

Another thin volume on the thin_pool
lvcreate --name lv_2 --virtualsize 2GB --thinpool vg_root/thin_pool

fsck 无需任何修复即可通过：
