OCI: Unable to Mount File System Due to Error "Filesystem has duplicate UUID can't mount"
in Linux
Applies To:
Oracle Cloud Infrastructure - Version N/A and later
Linux x86-64
Symptoms:
mount(8) command is failing with below error:
[root@xxxx ~]# mount /dev/sdg /plan_ui
mount: /plan_ui: wrong fs type, bad option, bad superblock on /dev/sdg, missing codepage or helper program, or other error.
[root@xxxx ~]#
Cause:
Duplicate UUID error can be seen in dmesg:
[1584759.367866] XFS (sdg): Filesystem has duplicate UUID d9ed2a83-f5a4-42c4-8e8e-a87fac03a4fe - can't mount
If the LUN restored from a backup, the metadata that contains UUID information for filesystem will be identical on both filesystems. This is because the copy and restore process copies metadata as well.
