[Ocfs2-users] Filesystem usage after mkfs.ocfs2

[Sunil Mushran]

The default mkfs params make 4 slots each with a 256M journal. That's 1G.
If you want them smaller, mkfs provides parameters to override the same.

Secondly, we compute based on the full device. Most other filesystems
deduct the blocks consumed by the fs on creation in their calculation.
