We have an Ubuntu 10.04 machine. I mounts a directory (statically, i.e. a line in /etc/fstab) on an NFS server.
After some usage, the mount will simply hang. Any attempt to access the mount (e.g. ls /somedir) will just hang, and will have to be kill -9'ed.
Trying to mount another NFS export on the same server, or another server, will simply fail (syscall failed). Trying to access the hung export from another machine works fine (i.e. the server side works, this is a client-side problem).
This is kernel 2.6.32-45-server.
What logs would you like? When trying to do this:
rpcdebug -m nfs -s all
All I see on an access attempt is:
Apr 17 10:47:53 brent kernel: [145406.995318] NFS: revalidating (0:15/2)
Apr 17 10:47:53 brent kernel: [145406.995326] NFS call getattr
If I do this:
rpcdebug - m rpc -s all
I get waaaaay too much info. :) This box also serves as an NFS server, but when this glitch happens, the NFS server is unaffected.
We cannot do upstream testing. We tried the latest kernel on another machine with the exact same config, and one of our network interfaces would not come up.
