Bug Description
Binary package hint: mdadm
I can mount exports from devices that do not reside on raid
I have tried many different ways to get raid mounted path to mount but keep getting access denied.
Client to same Server and Remote client to said server -> all the same result.
2 TB Mirror raid from either dmraid or mdadm.
mount -t nfs datahouse:
results in : mount.nfs: access denied by server while mounting datahouse:
I tried latest and greatest version of mdadm to create the array as well. The actual raid works fine in Nautilus and Terminal. I can access mounted raid. This problem is with nfs and the kernel or something. I can't find any relevant log entries to continue diagnosing.

Ok, after working with Neil Brown (I assume the architect of MDADM) he asked me a few questions and identified the issue as being with nfs-utils.

And this did the trick. Forcing version=3 allowed me to mount the nfs share. The question becomes why NFS3?
