[PKG-Openstack-devel] Bug#759216: Fwd: Re: Bug#759216: sheepdog: Init script missing corosync dependency

[Thomas Goirand]

Hi,

I believe this message should have reached the BTS, so I'm forwarding it
to the relevant bug.

My take on this: it's ok to add a "Should-Start: corosync" in the
sheepdog init script. It will work regardless if we're using corosync or
not (in other words: it can't hurt...).

If I hear nothing form the current maintainer of Sheepdog, I'll do that.

Hi,
I think this assumption is wrong.

Sheepdog can use different cluster managers.
Corosync has proven to be problematic in some situation and it doesn't
support anyway more than 10 nodes.

I strongly recommend to build sheepdog package so it supports also
zookeeper.
(If Im not worng, the package already use --enable-zookeper, but please
check it).
Zookeeper configuration is not more difficult than corosync, supports
way more nodes, it doesn't need to be run on each node.

Because we can't know what cluster manager the user is going to be
using, I think it's better not to start nor require corosync as dependency.

Valerio.
