Re: Network mounting problems

1997-05-19 Thread joost witteveen
 Hello All:
 
 I have been running into a vexing problem with a cluster of 8 Debian
 machines I am using for a Course in Computational Physics.
 
 All of the machines are running Debian 1.2 as installed in December 1996.
 I have not wanted to do much upgrading during the course of the semester.
 so students can log into any one of the machines and find their data
 files. 
 
 The problem is that if the systems are left to run for an extended period
 of time (over a week usually but as little as a few days even!) the /home
 directory becomes inaccessible at login even though the df command shows
 it to be mounted.  This causes a great deal of problems and means that I
 have to reboot the machines regularly.  It also means that if I am not
 around people start to complain.  As a side note, the server is usually
 quite stable and stays up for many weeks at a time. Just the other
 machines need to be rebooted because of this problem. The kernel version
 is 2.0.27.

So, I assume the clients mount their /home from a (the?) server via NFS?
If so, I used to have a lot of problems with the old nfsd, that used
to die on my every so often (escpecially if two clients mount and read
from the nfs disks at the same time). This was solved by upgrading to
a more recent nfsd. But alas, you don't indicate that any nfsd dies,
so you may be running into another problem. Still, upgrading the
server's nfsd (from the netstd package) may improve matters.

Currently installed on my system (without problems):

$ /usr/sbin/rpc.nfsd -v
Universal NFS Server 2.2beta25

$ dpkg -l netstd
ii  netstd  2.13-1 Networking binaries and daemons for Linux

Network mounting problems
