Re: CentOS 5 NFS clients fail to umount without -f options (Re: glusterfs-3.3.0qa38 released)

[Tomoaki Sato <tsato@xxxxxxxxxxxxx>]

It seems that hostname missmatch makes __mnt3svc_umount() fail.
 
operations:

[root@strk-001 ~]# mount -o vers=3 one:/one /mnt
[root@strk-001 ~]# showmount one
Hosts on one:
172.17.200.21:680
[root@strk-001 ~]# umount /mnt
