Just a quick note that this doesn't seem to be any sort of corruption
issue. I completely emptied all my shares (even removing lost+found) and
my namespace and rsynced the corresponding AFR shares and namespace. The
only thing different between the AFRs would be ctimes.
I restarted everything, and did:
ls -al /beast
ls: /beast: File exists
ls: /beast/.: File exists
total 8
drwxr-xr-x 2 root root 4096 2007-07-17 09:27 .
drwxr-xr-x 27 root root 4096 2007-07-02 10:18 ..
I also tried disabling readahead and writebehind (my only performance
translators). It didn't help. Changing the unify from alu to rr also
didn't help.
I then tried "glusterfs -f /etc/glusterfs/beast -n mirror0 /beast" to
mount a single AFR, no unify. It STILL produces the same messages.
I then tried "glusterfs -f /etc/glusterfs/beast -n share0-0 /beast" to
mount a simple, single share used as half of an AFR. Same issue.
I then stripped down a server to serve out one single storage/posix
share,
with no posix locks (I wasn't using any other translators on the server
side, apart from protocol/server, of course). I mounted that share as in
the previous attempt. No difference!
So, this issue occurs even with just protocol/client, protocol/server,
and
storage/posix in use. As barebones as you can get. Almost.
One more try. No glusterfsd, and glusterfs accesses a single
storage/posix directly:
ls -al /beast
ls: /beast: File exists
ls: /beast/.: File exists
total 8
drwxr-xr-x 2 root root 4096 2007-07-17 09:27 .
drwxr-xr-x 27 root root 4096 2007-07-02 10:18 ..
No difference, even with just glusterfs directly accessing a single,
local
storage/posix, with no other translators. Spec is simply:
volume share0
type storage/posix # POSIX FS translator
option directory /share0 # Export this directory
end-volume
Ubuntu Feisty, Fuse 2.6.3.
Any ideas?
Thanks,
Brent
