File System Issues

The following are known issues that are specific to file systems supported with Unbreakable Enterprise Kernel Release 5 Update 1.

ext4: Frequent repeated system shutdowns can cause file system corruption

If a system using ext4 is repeatedly and frequently shut down, the file system may be corrupted. This issue is considered to be a corner-case due to the difficulty required to replicate. The issue exists in upstream code and proposed patches are currently under review. (Bug ID 27547113)

xfs: xfs_repair allows the corruption of a directory to a symbolic link

An issue exists, where if an xfs directory becomes corrupted and appears as a symbolic link, the xfs_repair command does not detect the error and allows the corruption to remain. The issue is under investigation.

xfs: xfs_repair fails to repair the corrupted link counts

If an xfs file system is repaired by using the xfs_repair command, and there are invalid inode counts, the utility may fail to repair the corrupted link counts and return errors while verifying the link counts. The issue is currently under investigation, but appears to be related to the xfsprogs-4.15-1 package released with UEK R5. The issue may not appear when using the earlier xfsprogs-4.5.0-18.0.1 version of this package available in the ol7_latest yum repository. (Bug ID 28070680)
