Bug Description
Binary package hint: mdadm
According to MDADM the problem was diagnosed as the fallback to NFS3 was not happening and was fixed in nfs-utils 1.2.2.
Forcing -o vers=3 on the mount resolved the symptoms but why is NFS4 not working? What kind of performance is lost by using NFSv3 when NFSv4 is installed?
root@datahouse/# mount -t nfs datahouse:
mount.nfs: access denied by server while mounting datahouse:
root@datahouse/# mount -t nfs -o vers=3 datahouse:
!SUCCESS!
