This issue has been fixed by LU-8443, but I still can hit it in my local vm with this patch. At least, we need to add a version check to the script.

[Emoly Liu]

Since Sep.8, this issue has occurred 22 times, 9 on centos6.7, 10 on centos6.8, and has never happened on rhel7, so I suspect it is related to some mkfs.ext4 setting on centos6.x. I will investigate it.
