Created attachment 527925 [details] util-linux-2.20-umount-force-fix.patch Description of problem: It is impossible to umount an nfs share using the -f (force) option. Version-Release number of selected component (if applicable): nfs-utils-1.2.5-0.fc16 util-linux-2.20-1.fc16 How reproducible: 100% Steps to Reproduce: # mktemp -d /tmp/tmp.o3J5KAB8rG # mount -t nfs srv1:/export1 /tmp/tmp.o3J5KAB8rG # mount | grep /tmp/tmp.o3J5KAB8rG srv1:/export1 on /tmp/tmp.o3J5KAB8rG [...] # umount -t nfs -f /tmp/tmp.o3J5KAB8rG # mount | grep /tmp/tmp.o3J5KAB8rG srv1:/export1 on /tmp/tmp.o3J5KAB8rG [...] Actual results: The nfs share is not unmounted. Expected results: The nfs share must be unmounted. Additional info: The problem is in the libmount-2.20-1.fc16, the mnt_context_umount_setopt confuses the -f (force) option with the -f (fake) option used during mount. A patch to fix the issue is attached.
Fixed in upstream by commit ff4c00f94a82addaa8b8ca67dec1ea7a5283ae5b. The Fedora package will be updated ASAP. Thanks!
