<pre wrap="">I am looking for a fault tolerant solution. By this, I mean I want there to be an automatic switch over if one of the two storage servers goes down with no human intervention.
Initially, I followed this guide: <a class="moz-txt-link-freetext" href="https://help.ubuntu.com/community/HighlyAvailableNFS">https://help.ubuntu.com/community/HighlyAvailableNFS</a>
That works fine, but there are several steps that require human intervention in case of a server failure:
Promote secondary server to primary
Mount drbd partition to export path
Restart nfs-kernel-server (if necessary)
I was trying to get dual primaries setup, thinking that if one goes out the other will take over automatically. There just seems to be so many moving pieces that don't always work they way they are supposed to. I have been reading all the material I can get my hands on but a lot of it seems contradictory or only applicable on certain OS versions with certain versions of OCFS2, DRBD and Pacemaker.
It doesn't matter to me if it is master/slave or dual primaries. I am just trying to find something that actually works.

Linbit's own guide should suffice, it's what i used setting up my
own HA-NFS in the past month. I deviated in a few places from
exactly what is provided (mainly different mnemonic names for
primitives, etc) but overall it covers it in a very straightforward
way.<br>
