[Ocfs2-users] Much higher disk usage in OCFS2 then in XFS

[Markus Meyer]

Hi all,

I created a OCFS2 volume with a block size of 4kB and a clustersize of 
4kB. After I mounted the volume the first time there have been already 
over 600 MB in use. Then I started to copy a directory with a overall 
size of 1784 MB(measured on an XFS with "du"). After an hour about 4 
GB(!) have been used on the OCFS2 volume so I stopped the copy.
The files I copied are mostly smaller then 12kB.

Why is there such a big difference between XFS and OCFS2? Is it 
recommended to use OCFS2 for such small files(there are over 2 TB of them)?

Regards,
