[Gluster-users] faied start the glusterd after reboot

[songxin]

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
xin
