https://bugzilla.novell.com/show_bug.cgi?id=809226 https://bugzilla.novell.com/show_bug.cgi?id=809226#c42 --- Comment #42 from Neil Brown <nfbrown@suse.com> 2013-05-02 00:38:13 UTC --- I figured it out. When you mount localhost:/ on /mnt, and then 'ls -l /mnt", one of the things that it tries to 'stat' is /mnt/mnt, which is also /mnt. mountd checkis if it is ok to export /mnt but it isn't (you cannot reexport NFS filesystem). So mountd tell the kernel that /mnt cannot be exported. This information sits in the export cache holding a reference to /mnt So you cannot umount /mnt (it has a reference). The cache entry will time out after 30 minutes after which you should be able to unmount. Alternatively run "exportfs -f". This will flush the cache (a harmless process) and then allow you to unmount. In general if you have been using nfs you might need to "exportfs -f" before an unmount will succeed. (this doesn't explain the strange thing happening with /tmp for me, but that only happens on one machine, so might not be relevant). -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
