Sorry for not getting arount to this sooner, I've been shuffling data
around haphazardly, trying to empty drives and convert them to ext3. I've
gotten it to 2 xfs branches, and 5 ext3 branches. With this setup, all of
the problems seem to dissappear. I've tried this with both xino=/tmp/xino
and with xino=/xfs-partition/xino. I haven't had any problems with both
the last version of aufs that I used 03-27 and with this weeks release
04-02. I've tested this with a command similar to
find . -exec stat '{}' -c "%i %N" ';' | sort -n | uniq -w 7
which will find out if there are multiple files with the same inode. I do
have a bunch, but that's just because all of the underlying files seem to
be hard linked.
On a related note, This system used to have 512 Mb RAM. Between the last
tests, and this test, I've upgraded to 1 Gb. I've noticed that my caches
and buffers are still usually taking up nearly all of my memory, and there
seems to be about 300 Mb of unaccounted memory missing. I don't think
this has anything to do with aufs, but aufs may have been getting sad
because of the lack of memory.
To reiterate: everything seems to be good.
