But maybe I was wrong! Maybe I'm wrong, but asking for free/used blocks is ambiguous to say the least. If he wants free/used blocks, then we just need to forward port this kernel branch: https://git.kernel.org/cgit/linux/kernel/git/dgc/linux-xfs.git/log/?h=fiemapfs And this xfsprogs branch: https://git.kernel.org/cgit/fs/xfs/xfsprogs-dev.git/log/?h=spaceman Cheers, Dave. -- Dave Chinner david@xxxxxxxxxxxxx _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
