NFS Ganesha is built without RADOS support

[Chris MacNaughton]

The debian/rules file to build nfs-ganesha disables default build features that enable using Ceph as a backend for storing config and client recovery data:

-DUSE_RADOS_RECOV=NO
-DRADOS_URLS=NO

[Impact]

It is not possible to enable Ceph backends for either configuration nor recovery. When attempting to do so, Ganesha will fail on start because of unknown configuration options.

[Test Plan]

Deploy manila + Ganesha with the OpenStack Charms and confirm that RADOS URLs are recognized, and that configuration can be stored in Ceph. Fully validating this does require https://bugs.launchpad.net/ubuntu/+source/nfs-ganesha/+bug/1927208 as well.

To verify the functionality is complete and functional, a new NFS share will be created in nfs-ganesha via Manila, the share will be backed by CephFS, and the share's functionality will be validated (mounted onto two distinct machines and read/write across that), then the nfs-ganesha process will be restarted, and the same validation will be done again.

[Where problems could occur]

The most likely place that issues could occur is in URL based include handling, as this change enables handing of rados: scheme URLs.

Additionally, this enables the Ceph backed recovery backend driver for Ganesha but does not change the default.

Hello Chris, or anyone else affected,

Accepted nfs-ganesha into focal-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/nfs-ganesha/3.0.3-0ubuntu3.1 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, what testing has been performed on the package and change the tag from verification-needed-focal to verification-done-focal. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-focal. 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.
