Applies To:

Oracle Cloud Infrastructure - Version N/A and later
Linux x86-64

Goal:

How to check whether the XFS filesystem is using the legacy v4 format or the newer v5 format.

Solution:

To check whether the XFS filesystem is using the legacy v4 format or the newer v5 format, just run the xfs_db command against the mount point for the corresponding XFS filesystem.

This is an example of an XFS filesystem on OL7 running in v4 format.

# xfs_db -r /db
