Decreasing slots just release the volume we reserved for journal, so it didn't help for free space fragmentation actually. I have looked into your system_dir output, the journal size is only 256M, so in total you will have 512M more free space. Don't know whether it is big enough for you. > > tunefs.ocfs2 -N 2 /dev/mapper/store This is an offline action, so you need to umount the volume from all the nodes to go ahead.
Another way is that you can cp the file to another volume, remove it and then cp back. It should be contiguous enough.
