The test cluster is gone now, so not sure ... Beekhof might know.

I know it's big enough that the transition graph could get too big to
send via IPC, and we had to re-enable pengine's ability to write it to
disk instead, and have the crmd read it from disk.

Hi Ken,

That's really cool. What's the size of the CIB with that kind of
configuration? I guess it would compress pretty well, but still.

Cheers,

[ClusterLabs] Pacemaker 1.1.18 Release Candidate 4

2017-11-02 Thread Ken Gaillot 
I decided to do another release candidate, because we had a large
number of changes since rc3. The fourth release candidate for Pacemaker
version 1.1.18 is now available at:

https://github.com/ClusterLabs/pacemaker/releases/tag/Pacemaker-1.1.18-
rc4

The big changes are numerous scalability improvements and bundle fixes.
We're starting to test Pacemaker with as many as 1,500 bundles (Docker
containers) running on 20 guest nodes running on three 56-core physical
cluster nodes.

For details on the changes in this release, see the ChangeLog.

This is likely to be the last release candidate before the final
release next week. Any testing you can do is very welcome.
