Hi,
Thank you for reply.
The file .nfs0000000001722f4000000002 is a file but not a directory.
And I found that it is there when the gluster is running.
root@128:/# ls -al /var/lib/glusterd/snaps/
total 8
drwxr-xr-x 2 root root 4096 Feb 26 2016 .
drwxr-xr-x 14 root root 4096 Feb 26 2016 ..
-rw------- 1 root root 0 Feb 26 2016 .nfs0000000006c02b090000000c
-rw------- 1 root root 0 Feb 26 2016 missed_snaps_list
If I abnormal shutdown the my board， the file will be there when the board reboot.And some error will happened as below.
...

Do you know why is that？
Thanks,
