Which fragmentation factor is allowable for xfs (not impact on performance)? # xfs_db -c frag -r /dev/sda actual 4908781, ideal 2801391, fragmentation factor 42.93% Note, this number is largely meaningless. Files on this filesystem average 1.75 extents per file # mount | grep sda /dev/sda on /home type xfs (rw,relatime,seclabel,attr2,inode64,noquota) # df -h | grep sda /dev/sda 11T 5.3T 5.7T 49% /home I think it too much for partition which are half free. It would also be interesting to see the fragmentation in the context of files, but I have not found anywhere how to look at it. Thanks. -- Best Regards, Mike Gavrilov.
