Comment 1 for bug 1838024

Last autopkgtest that succeed shows:

autopkgtest [07:14:15]: test pacemaker: [-----------------------
+ sleep 60
+ crm_mon -1
+ hostname -s
+ fgrep -20 Online: [ autopkgtest ]

Before the upgrade, the test has also failed with similar (as now) output:

autopkgtest [20:08:18]: test pacemaker: [-----------------------
+ sleep 60
+ crm_mon -1
+ hostname -s
+ fgrep -20 Online: [ autopkgtest ]
autopkgtest [20:09:18]: test pacemaker: -----------------------]

pacemaker FAIL non-zero exit status 1
autopkgtest [20:09:18]: @@@@@@@@@@@@@@@@@@@@ summary
pacemaker FAIL non-zero exit status 1

And after the upgrade, just one test and failed the same way:

autopkgtest [20:26:39]: test pacemaker: [-----------------------
+ ulimit -H -l unlimited
+ sleep 25
+ fgrep -20 Online: [ node1 ]
+ crm_mon -1
autopkgtest [20:27:05]: test pacemaker: -----------------------]
autopkgtest [20:27:05]: test pacemaker: - - - - - - - - - - results - - - - - - - - - -
pacemaker FAIL non-zero exit status 1
autopkgtest [20:27:06]: @@@@@@@@@@@@@@@@@@@@ summary
pacemaker FAIL non-zero exit status 1

----

Meaning, AT LEAST, the test is flakky and likely because of timing issues waiting for corosync or some other reason (can't reproduce locally).
