ugh. ocfs2 may not do for us. it does not support quotas..i have to check if
they mean disk quota or user quota. we use user disk space quotas on almost

Note: Features which OCFS2 does not support yet:
               - extended attributes
  │ - shared writeable mmap
  │ - loopback is supported, but data written will not

  │ - quotas

  │ - POSIX ACLs
