Description of problem:
If I shutdown my system, the system hangs while "Unmounting local file
systems". I narrowed down this problem, by stopping Squid (service squid
stop), and trying to umount /webcache (the mount point for my reiserfs file
sytem that Squid is using). The umount command simply hangs, and cannot be
killed. I believe this problem was introduced with an update to the mount
package, because this was not happening with my initial implementation of
reiserfs on RedHat 7.1. The umount -V command reports the following
Steps to Reproduce:
1.mount any reiserfs file system
2.umount any reiserfs file system
Actual Results: umount hangs, and cannot be killed.
Expected Results: umount should finish, and the file system should no
longer be mounted.
I believe this issue was introduced with a patch to mount. The umount -V
command reports the following version information:
Did you upgrade your kernel? If so this is probably a duplicate of bug 45628.
I looked at bug 45628, and it does appear to be the same problem, because I did
upgrade to the 2.4.3-12 kernel.
This problem has been fixed, and I have since upgraded my system to RedHat 7.2,
where the problem is also no longer occuring. You can close this bug.
