Hi Andrew,
I have followed your advice and updated Pacemaker/Corosync by installing
a fresh Debian Sid but I still have the issue with the following packages:
# uname -a
Linux testvm1 3.13-1-amd64 #1 SMP Debian 3.13.10-1 (2014-04-15) x86_64
GNU/Linux
# cat /etc/issue && dpkg -l | egrep "corosync|pacemaker|drbd"
Debian GNU/Linux jessie/sid \n \l
ii corosync 1.4.6-1 amd64
Standards-based cluster framework (daemon and modules)
ii crmsh 1.2.6+git+e77add-1.2 amd64
CRM shell for the pacemaker cluster manager
ii drbd8-utils 2:8.4.4-1 amd64
RAID 1 over TCP/IP for Linux (user utilities)
ii pacemaker 1.1.10+git20130802-4 amd64
HA cluster resource manager
ii pacemaker-cli-utils 1.1.10+git20130802-4 amd64
Command line interface utilities for Pacemaker
And with the "experimental" packages, I cannot connect to the cluster
via crmsh too:
# cat /etc/issue && dpkg -l | egrep "corosync|pacemaker|drbd"
Debian GNU/Linux jessie/sid \n \l
ii corosync 2.3.3-1 amd64
Standards-based cluster framework (daemon and modules)
ii crmsh 1.2.6+git+e77add-1.2 amd64
CRM shell for the pacemaker cluster manager
ii drbd8-utils 2:8.4.4-1 amd64
RAID 1 over TCP/IP for Linux (user utilities)
ii libcorosync-common4 2.3.3-1 amd64
Standards-based cluster framework, common library
ii pacemaker 1.1.11-1 amd64
HA cluster resource manager
ii pacemaker-cli-utils 1.1.11-1 amd64
Command line interface utilities for Pacemaker
I will try to build last versions of Pacemaker/Corosync on a Debian
Wheezy before reporting my issue via Bugzilla.
Thanks for your help.
