Ok, what we need is the following. First, try to reproduce the
problem on a small filesystem (say a few GB). Once you've reproduced
the problem, unmount and remount the filesystem to get the log
replayed, then take a xfs_metadump image of the filesystem. Put the
metadump image somewhere that can be downloaded (ftp/web site) and
let us know where it is.
If this is anything like the previous problem I found and fixed,
then it will be a corner-case bug that is only triggered by a
specific layout of free space and we need the filesystem image
to be able to work out exactly what corner case is broken....

It will be an AG that is out of space, not the entire filesystem.
