[Brian Murray]

Hello Kirill, or anyone else affected,

Accepted samba into disco-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/samba/2:4.10.0+dfsg-
0ubuntu2.3 in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested and change the tag from
verification-needed-disco to verification-done-disco. If it does not fix
the bug for you, please add a comment stating that, and change the tag
to verification-failed-disco. In either case, without details of your
testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Bug description:
  [Impact]

   * SAMBA CTDB cluster suite does not work for High Available NFS setups
   * LP: #1821775 - ctdb cannot create PID file
   * LP: #1828799 - Package ctdb does not create directories in /var/lib/ctdb

  [Test Case]

   * Installing CTDB and trying to start the service (check /var/log/ctdb/ctdb.log):
     - no /etc/ctdb/nodes file, can't start
     - /var/lib/ctdb/volatile does not exist
     - and some other errors addressed in here

  [Regression Potential]

   * very small chances of causing issues to other parts of samba
   * ctdb app is placed in a specific directory and is not working nowadays

  [Other Info]

   * Documentation on how to enable this SRU:
  https://discourse.ubuntu.com/t/ctdb-create-a-3-node-nfs-ha-backed-by-a
  -clustered-filesystem/11608

  ORIGINAL DESCRIPTION:

   * n/a

  Binary package hint: ctdb

  CTDB suppose to detect distro-specific Samba/NFS/Apache settings, or
  at least provide the way to manual tweaking/config of ctdb. In the
  current state looks like ctdb has been ported from RH-based
  distribution and its partially aware of some Debian-specific
  settings/files/scripts locations, but completely unaware of Ubuntu.
  For examle: ctdb is able to control NFS daemons, but it never looks
  for /etc/init.d/nfs-kernel-server for startup or /etc/default/nfs-
  kernel-server for settings.

  1) Found on Ubuntu 10.04
  2) CTDB version: 1.0.108-3ubuntu3
  3) Expected: ability of ctdb to control nfs-kernel-server
  4) Happened: without significant ctdb script changes (adding sections, aware of ubuntu-specific nfs- and samba- config- and startup scripts locations) ctdb is not able to function properly
