OCI: How to change or add a label to an XFS file system

APPLIES TO:

Oracle Cloud Infrastructure

Linux x86-64

GOAL:

Some systems use LABELS instead of UUIDs to mount their file systems. This is particularly true with Exadata systems. If an instance is using a label to mount a file system, for example ‘DBSYS’ and the label has been removed from the file system the kernel won’t be able to find it and it will crash with a kernel panic halt.

SOLUTION:

To add a label to an XFS system this can be performed using xfs_admin command.

1. Validate if the file system has currently a label with:

$ xfs_admin -l /path/to/device
