Hi Steven,
Even though i stumbled upon this issue multiple times already, I can't
really fully reproduce it yet. It always happens to me when i'm
live-migrating ( and libvirt create a bleh.xml.new file inthere ).
What gfs2_edit command output should i provide to you when it happens
again ( and i'm sure it will )? I'll make sure to post it here on the
list as soon as it occurs. Some other
commands,logs,outputs you think can be handy to figure this one out? I
feel like an Ubuntu cluster guinnea pig :)
Thanks for your help so far!
Kind regards,
Bart

The output from fsck doesn't really give any clues as to the cause.
The reclaiming of unlinked inodes is a fairly normal thing to see,
particularly if there has been some kind of crash just before running
fsck and it is nothing to worry about.
The real issue is why you got this out of space error in the first
place, when there appears to be plenty of free blocks left. It would
be
worth checking with gfs2_edit just to be sure that the allocation
bitmaps are not full, even if the summary information says otherwise.
Can you easily reproduce this issue, or is this something that has
just
occurred once?
