- Collect the sosreport log,but the /var/log/message is binary file and could not be checked.
Resolution
- hardisk error lead to the problem
- Change the hardisk to test if the problem would occur again
- umount the filesystem and use fsck to check the filesystem
- You should bakup the data before use the fsck tool to check the filesystem.
Root Cause
hardisk faulty lead to the filesystem readonly.
