Hi, using ubuntu 9.04, kernel version 2.6.28-18 and xfsprog v2.10.2-1
I'm trying to defragment a drive. If I use xfs_db to check for
fragmentation it shows for example that a file has 20k+ fragments:
inode 578505506 actual 23240 ideal 1mapping the inode to the file and running xfs_frs states that the file is fully defragmented.
Also running xfs_frs says the drive is defragmented while xfs_db for example reports 300k fragments.
Which is right? and is it possible to defragment the file assuming it is fragmented so badly, if so how?
