Thanks for doing this work Arek, I think it will be useful for some users and defintively is cleaners than what we have now. > I started doing that by splitting every group+project handling code into > separate group and project one.

Do you mean an old filesystem without the SEPARATEQUOTA bit set here? > New filesystem (without quota inodes allocated yet), when mounted, gets new > quota inode allocated for project quota and SEPARATEQUOTA feature bit set. I think we need the SEPARATEQUOTA bit set explicitly by mkfs.xfs/xfs_admin. But once we start using project quotas with the bit set the above sounds fine. > Converting old fs to separate quota isn't currently solved.

We know what sb_gquotino is used for currently from sb_qflags. If it's used for group quota we can simply set the SEPARATEQUOTA bit and we're done. To convert a filesystem using project quotas to SEPARATEQUOTA sb_gquotino needs to be cleared and instead the new sb_pquotino field needs to point to the project quota inode. Need to go now, I'll answer to your other questions once I had some more time to review them. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
