Description yexue2015 2019-08-01 18:56:05 UTC

Description of problem:
Some files were suddenly missing. Then after a couple of days, the missing files appeared again (not been damaged).

Under one of my folders, there were two sub-folders and four files. At a point, two files were missing and more files under those two sub-folders were missing randomly. There should be 210 files under each of the sub-folders, but after the missing occurs, there were 125 and 138 files left. I can no longer read the files that are missing. However, after a few days. I found the missing files were back.

Version-Release number of selected component (if applicable):
rpm -qa | grep glusterfs
glusterfs-6.1-1.el7.x86_64
