I have a /home partition in a separate disk with XFS, how do I de-fragment it ? (on-line or off-line)
I haven't tried anything yet and the / partition has BTRFS. Also how to schedule it would be nice. But I can check that out in already responded questions.
This was the output :
sudo xfs_db -c frag -r /dev/sdb5
actual 329394, ideal 301436, fragmentation factor 8.49%1 Answer
XFS provides a filesystem defragmentation utility, xfs_fsr that can defragment the files on a mounted and active XFS filesystem.
It can be useful to view XFS fragmentation periodically.
xfs_fsr improves the organization of mounted filesystems. The reorganization algorithm operates on one file at a time, compacting or otherwise improving the layout of the file extents.
Inspect fragmentation levels
To see how much fragmentation your file system currently has:
sudo xfs_db -c frag -r /dev/sd??To begin defragmentation, use the xfs_fsr command which is included with the xfsprogs package.
sudo xfs_fsr /dev/sd??Change ?? to what corresponds your partition
