Subject: Problem when using a nfs mounted filesystem.
Date: Wed, 21 Nov 2001 15:46:32 -0800 [thread overview]
Message-ID: <3BFC3CD8.3B955DA8@sun.com> (raw)
[1.] One line summary of the problem:
Problem when using a nfs mounted filesystem.
[2.] Full description of the problem/report:
I mounted a remote filesystem on my machine with the following command:
[root@localhost mnt]# mount -t nfs -o "hard,intr,nodev,nosuid"
hats105:/export1
/mnt/export1
[root@localhost mnt]# df -ak
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/hda1 1597004 141176 1374704 10% /

hats105:/export1 4113280 1476736 2595392 37% /mnt/export1
Everything seems OK for a while since I can access any directory/file
under
/mnt/export1. Suddenly, after a few minutes, I cannot access anymore
this file
system. All my programs which where using these filesystems are frozen
and I they dont even receive any signals. I cannot umount this
filesystem
neither. I checked the nfs server is still up and running so the problem
seems to come from the client side.
[3.] Keywords (i.e., modules, networking, kernel):
file system, NFS
[4.] Kernel version (from /proc/version):
[root@localhost mnt]# cat /proc/version
