XFS file system defragmentation

GNU/Linux

File system defragmentation is a not as obvious task in Linux/Unix as it is in Windows. Modern Unix file systems are designed to avoid fragmentation. However, in rare cases I explicitly want to defrag my favored XFS partitions, and it’s done this way:

Check fragmentation percentage:

# xfs_db -r -c frag /dev/sdaX


Defrag:

# xfs_fsr /dev/sdaX
