Hi,
/var/lib/glusterd/snaps/ contains only 1 file called missed_snaps_list. Apart from it, there are only directories created with
the snap names. Is .nfs0000000001722f4000000002, that you saw in /var/lib/glusterd a file or a directory. If it's a file, then it
was not placed there as part of snapshotting any volume. If it's a directory, then did you try creating a snapshot with such a name.
Regards,
Avra

If I run "reboot" on the a node��there are not .snap files on A node after reboot.
Does the snap file only appear after unexpect reboot��
Why its size is 0 byte��
In this situation ��is a right method to solve this problem removing the snap file?
thanks

Thanks for your reply.
Do I need check all files in /var/lib/glusterd/*?
Must all files be same in A node and B node?
Yes, they should be identical.
I found that the size of
file /var/lib/glusterd/snaps/.nfs0000000001722f4000000002 is 0 bytes
after A board reboot.
So glusterd can't restore by this snap file on A node.
Is it right?
Yes, looks like that.

I believe you and Abhishek are from the same group and sharing the
common set up. Could you check the content of /var/lib/glusterd/* in
board B (post reboot and before starting glusterd) matches with
/var/lib/glusterd/* from board A?

1.systemctl start glusterd (A board)
2.systemctl start glusterd (B board)
3.gluster peer probe 128.224.95.140 (A board)
4.gluster volume create gv0 replica 2 128.224.95.140:/tmp/brick1/gv0
128.224.162.255:/data/brick/gv0 force (local board)
5.gluster volume start gv0 (A board)
6.press the reset button on the A board.It is a develop board so it has
a reset button that is similar to reset button on pc (A board)

I want to know if it is nomal.
