[Samba] DFS Shares (Clustered)

[Shaun Glass]

Hi,

As requested :

search our.domain.com
nameserver 10.11.12.13
nameserver 10.11.12.14
options rotate
options timeout:1

First DNS Server sits in original location, second is in location we
fail over to. As for handling remount ... just manually from command
line.

If there is indeed a fix down the line we can wait. Our DR exercises
are normally twice a year and at least 6 months or more until then.

Regards

Shaun
