Red Hat Bugzilla – Bug 505773
NFS mount fails, "incorrect mount option specified
Last modified: 2009-06-13 14:35:58 EDT
[root@trinity ~]# mount -v -t nfs discworld:/scratch /scratch
mount.nfs: timeout set for Sat Jun 13 18:53:44 2009
mount.nfs: text-based options: 'addr=<$IPADDR>' (placeholder for sanitization)
mount.nfs: mount(2): Operation not supported
mount.nfs: an incorrect mount option was specified
So DNS resolution works fine, no fstab entry, plain simple NFS mount. Fresh Fedora 11 installation, all post-release updates installed.
Workaround: using busybox.
[root@trinity ~]# busybox mount -t nfs discworld:/scratch /scratch
Something is broken with mount.nfs I guess.
Possibly duplicate of 505018 - very old NFS server... I'm going to test the pending nfs-utils update and report back.
Confirmation: The "-o proto=udp" workaround works fine.
nfs-utils-1.2.0-3.fc11.i586.rpm does NOT fix the issue.
I'm going to re-open Bug #505018 so we have all things in one place and close this one off as DUPLICATE.
