Brent, very interesting diagnosis! is it possible for you to re-create the 'posix only' setup (no server/client) and again do 'strace ls -ial /beast' ? we are not able to reproduce this error at our setup. thanks avati 2007/7/17, Brent A Nelson <brent@xxxxxxxxxxxx>:
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?
