samba - Apr 2016 - Updating from 4.1 + CTDB to 4.2/CTDB?

Dear list,

We are about to upgrade to Samba 4.2.9 from sernet-samba 4.1.6 + CTDB 1.0.114.7
running on top of GPFS.  My understanding is that as of 4.2, CTDB is now part of
Samba.  So does this mean we need to uninstall all of our sernet-samba and ctdb
RPMs (we are on CentOS 6), then install the sernet-samba 4.2.9 rpms and
reconfigure everything for CTDB?  For those who have done this, how different
does CTDB look in the samba 4.2 tree, vs. the older, separate packages?  I
assume GPFS support is built-in with the sernet packages?

Any advice appreciated - trying to get this knocked out before April 12...

Many thanks,

Although CTDB is now part of the Samba source tree, CTDB is still
usually shipped as a separate binary package.

At https://download.sernet.de/packages/samba/4.2/centos/6/x86_64/ (via
https://portal.enterprisesamba.com/) I can see
sernet-samba-ctdb-4.2.9-19.el6.x86_64.rpm.

This looks to contain the standard CTDB stuff.

Although CTDB has gone through a lot of changes in recent years, the
core configuration should be similar to what you already have.

That could be challenging.  Apart from suggesting that you watch the
logs carefully when starting CTDB, I would suggest contacting SerNet if
you are using their packages.

peace & happiness,
