Dear Ceph Users,
There was a question at the CLT today about the nfs-ganesha builds at:
https://download.ceph.com/nfs-ganesha/
Are people actively using those? Is there a reason you don't use the
builds from https://download.nfs-ganesha.org/ (which links to the
Storage SIG in the case of CentOS and has builds for SUSE, Debian, and
Ubuntu).
we are currently using these — but the interesting question is indeed why we
do, and whether we should still do that ;-).
When choosing which repo to pick (two years ago), we found the packages on
download.ceph.com were built against the different Ceph releases:
https://download.ceph.com/nfs-ganesha/rpm-V2.7-stable/
while the packages on download.nfs-ganesha.org (for the releases at that time,
e.g. V2.7) did not have Ceph-version specific builds yet.
Form this, I assumed that it would be more safe to use the releases from
download.ceph.com which were built against a selected Ceph major release
matching the Ceph release we are running,
to avoid potential ABI incompatibilities.
Since the storage SIG also builds nfs-ganesha against different Ceph releases,
this argument should be gone — but one thing remains unclear to me:
Is somebody already using the "mix" of Ceph packages from download.ceph.com
combined with storage SIG packages of nfs-ganesha?
Alternatively, it might be best for Ceph users on RHEL-based systems to switch
all packages to rely on the storage SIG
(it is something we have to plan for anyways since we'd like to stay on a
RedHat Rebuild OS instead of switching to Stream,
and the storage SIG keeps building on RHEL8 for now[0], so this seems to be
the safe way to go for users of RedHat Rebuild systems).
So to summarize, my questions would be:
- Is mixing packages from download.ceph.com and the storage SIG (for
nfs-ganesha) a healthy thing to do?
- For RedHat Rebuild users, would the recommendation be to use the storage SIG for
"everything" instead of doing the mix?
This would mean to avoid all packages on download.ceph.com, though.
- In any case, what would be the timeline between stopping "building" and stopping
"distributing"?
To ease migration (if needed), it would of course be nice to have a longer
time in which the old packages are still distributed,
even if the building of new versions is stopped.
Cheers (and a happy new year!),

Asking another way -- if we stop building nfs-ganesha and distributing
them on download.ceph.com -- what would break?
Thanks!
Dan
