- On RHEL 7.4 kernel (kernel-3.10.0-693.el7) or higher, a file system can not be mounted.
- The affected Filesystem has been online resized (grow) previously with resize2fs, and after some time, it's size has been reduced (FS Shrink).
# dmesgoutput after the mount attempt shows: "EXT4-fs
: first meta block group too large: X (group descriptor block count Y)".
- The file system can be mounted when booting into a pre-RHEL 7.4 kernel.
- Repairing the file system does not allow the file system to be mounted when booting into RHEL 7.4 kernel or higher.
