Hi,
I am facing couple of issues with nfsv4 mounts
1. Some times mount command cannot mount the exported
filesytem. mount gives error "Mount: File exists"
When i used a different mount point, it gets
mounted

One more problem i see is that i can mount
exports (with gss/krb5 option) using server FQDN
and not using ip address irrespective of presence of=20
sec=3Dkrb5 option of mount.Is this because servername
used for mounting should be same as one in keytab
file of server when exportfs is done with gss/krb5?
thanks,
kiran
