[Ocfs2-users] Large difference between space used on reiserfs vs
ocfs2

If you have lots of small files, it could happen. The basic space allocation unit is one block. If I am not mistaken on OCFS2 the default is 4k.
A quick search on google shows that Reiserfs can coalesce small files together and save space.
You could try to format your OCFS partition with a smaller block size, near the average file size.
Other possible explanation for this (That is, without filesystem corruption) is a large file that was deleted but is still in use by some process. The space remains allocated until you kill the process.

Luis

I have all of my web files for my apache servers on multiple machines placed on ocfs2 volumes. I recently did an rsync to a reiserfs volume on an external usb harddrive, and df reports the following:
(ocfs2 is on top, reiserfs on bottom)
/dev/sde5 218757056 176814592 41942464 81% /mnt/www
/dev/sdd1 732549604 117493932 615055672 17% /mnt/pba-web
Is this normal?
Thanks,
Michael
