Thanks for the info, but I still don't understand if this is a normal behaviour or not.
For me, at least, it's not very useful if the global bitmap is 6 times larger than the data I'm putting on it, and after deleting everything, this bitmap doesn't decrease in size.
Regards,

1. The global bitmap in ocfs2 maps all the clusters on the disk. That
includes,
the space used by the super block, root dir, system dir, system files, etc.
Hence the usage on a clean fs. Most of this space is being used by the
journals.
# echo "stat //journal:0000" | debugfs.ocfs2 -n /dev/sdX
2. ocfs2 does not preallocate space for inodes. It allocates space on
demand.
You can view the space allocated to inodes for slot 0 as follows:
# echo "stat //inode_alloc:0000" | debugfs.ocfs2 -n /dev/sdX
3. du does not reflect space used by filesystem metadata.
