Unable to umount cifs share
Last modified: 2008-04-04 09:23:09 EDT
Description of problem: Trying to unmount a cifs share gives error that it only unmounts cifs filesystems. Version-Release number of selected component (if applicable): samba-client-3.0.22-1.fc5 How reproducible: Every time. Steps to Reproduce: 1. Mount a cifs share on to the system. 2. Try to umount the share. 3. Actual results: Error displayed: This utility only unmounts cifs filesystems. This utility only unmounts cifs filesystems. Expected results: No error messages. The share should unmount. Additional info: The mount command shows: //ilsabc.uopnet.plymouth.ac.uk/Grid on /root/gridshare type cifs (rw,mand,noexec,nosuid,nodev) The umount command command gives: umount /root/gridshare This utility only unmounts cifs filesystems. This utility only unmounts cifs filesystems. Not sure why it displays it twice. We cannot now unmount this share at all. SELinux is disabled on the system (I read that that may be a cause, but not in this case). John.
Created attachment 130608 [details] Output of 'strace -Ff umount /root/gridshare' I ran the strace command in case the output was of any help.

I have tried this on a different server running Fedora 8 (using samba-client-3.0.28a-0.fc8). Unmounting the cifs partition gives no error. As such I think we can close this call as fixed. (Unfortunately the original server is still running FC5, but hopefully that will change over the next few months.) Many thanks, John.
