Description of problem:
The remote filesystem is mounted, then timed-out, and then it is never
The kernel doesn't allow unmounting the direct mountpoint itself, making it
impossible to restart Amd without rebooting.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Mount a remote system(I mount an SGI octane running IRIX6.5) via amd
2.cd to a directory on the amd mounted system and leave it untouched for a
3.do "df" in a separate shell to find
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/sda1 4134900 1843020 2081832 47% /
/dev/sda5 9288792 8678012 138876 99% /u
/dev/sda7 3194048 1318468 1713328 44% /usr/INA
og:/scratch 0 1 0 0%
og:/scratch2 0 1 0 0%
og:/scratch3 0 1 0 0%
og:/u/wk 0 1 0 0% /amd/og/root/u/wk
Actual Results: The amd links hang and report zero size in "df".
The directories which were mounted are now inaccessible.
Only recourse is to reboot the machine. This often fails because on reboot
it complains that it can not shutdown amd due to live links.
Expected Results: If I have "cd"'d to a directory via amd, the link should
remain active a s long as I am in that directory.
At the URL
there is a patch for some of the LINUX kernels, but the patch must not have
been aplied to the redhat distributed kernels.
I am submitting this report to make sure that future versions of reshat
distributions include this patch.
