Description

There are 4 snapshots under the /mnt/kcephfs/.snap/:

[root@lxbceph1 kcephfs]# ls /mnt/kcephfs/.snap/
ddd  fff  fffd  snap3

But when stating the /mnt/kcephfs/.snap/ directory, I hit one time it show as -2:

[root@lxbceph1 kcephfs]# stat /mnt/kcephfs/.snap/
  File: .snap/
  Size: -2            Blocks: 0          IO Block: 65536  directory
Device: 0h/0d    Inode: 1           Links: 1
Access: (0755/drwxr-xr-x)  Uid: (    0/    root)   Gid: (    0/    root)
Context: system_u:object_r:cephfs_t:s0
Access: 1970-01-01 08:00:00.000000000 +0800

But mostly it will show as 0:

[root@lxbceph1 kcephfs]# stat /mnt/kcephfs/.snap
  File: .snap
  Size: 0             Blocks: 0          IO Block: 65536  directory
Device: 0h/0d    Inode: 1           Links: 2

Context: system_u:object_r:cephfs_t:s0

But 4 is as expected.
