NFS server vanishing (but only with automounter)

[Paul Mezzanini]

Ok, I'm facing a very very strange problem. My systems are up just fine then all of a sudden the automounter just stops mounting directories. If I fire off a manual mount it works fine.

Here is the first error that I see in my syslog:

Feb 13 14:19:48 dewey automountd[798]: stat /users/students: Connection reset by peer
Feb 13 14:19:48 dewey automountd[798]: errno 232
Feb 13 14:19:48 dewey automountd[798]: server auto.direct is up but can not get the device id! errno= 232

Here is another interesting snippit from slightly farter down the log file:
Feb 13 17:15:05 happy automountd[799]: stat /users/students: Connection refused
Feb 13 17:15:05 happy automountd[799]: errno 239
Feb 13 17:15:05 happy automountd[799]: server auto.direct is up but can not get the device id! errno= 239
Feb 13 17:15:07 happy automountd[799]: server jafar:/users/students is up but can not get the device id! errno= 239
Feb 13 17:15:29 happy automountd[799]: server auto.direct is up but can not get the device id! errno= 239
Feb 13 17:15:31 happy automountd[799]: server jafar:/users/students is up but can not get the device id! errno= 239
Feb 13 17:15:31 happy vmunix: NFS getattr failed for server jafar: RPC: (unknown error code)
Feb 13 17:15:31 happy above message repeats 3 times
Feb 13 17:15:31 happy automountd[799]: dev ff000035, rdev 0 not in mnttab

Any ideas? It only seems to be happening on one of the two file servers (jafar)

(man I hope those log entries dont get mangled with the paste... this window I'm entering data in is small)

Hi,

Install the latest Kernel (PHKL) and Networking (PHNE) patches. Also check the permissions for the /etc/hosts file. It should be 'world' readable.

HTH,
