[sheepdog] [PATCH 0/1] block: future of sheepdog storage driver ?

[Daniel P. Berrangé]

2 years back I proposed dropping the sheepdog mailing list from the
MAINTAINERS file, but somehow the patch never got picked up:

  https://lists.gnu.org/archive/html/qemu-block/2018-03/msg01048.html

So here I am with the same patch again.

I further looked at the sheepdog project though, and I'm wondering
if we actually want to keep the sheepdog storage driver at all.

This thread from a little over a year ago:

  http://lists.wpkg.org/pipermail/sheepdog/2019-March/thread.html

clearly states that sheepdog is no longer actively developed. The only
mentioned users are some companies who are said to have it for legacy
reasons with plans to replace it by Ceph. There is talk about cutting
out existing features to turn it into a simple demo of how to write a
distributed block service. There is no evidence of anyone working on
that idea.

No real commits to git since Jan 2018 and that's just dealing with
technical debt.

There is essentially no activity on the mailing list aside from
patches to QEMU that get CC'd due to our MAINTAINERS entry, if and
when someone processes the moderator queue.

Fedora packages for sheepdog failed to build from upstream source
because of the more strict linker that no longer merges duplicate
global symbols. So we patch it to add the missing "extern" annotations.
Upstream source remains broken for everyone else.

AFAIK, none of our containers or VMs include the sheepdog server
packages, so we have no testing coverage for it in CI that I see.

Does someone have a compelling reason for QEMU to keep supporting
this driver, other than the fact that it already exists ?

If not, it looks like a candidate for deprecating in QEMU with a
view to later removing it.
