shamand service hangs on starting:
~# service shamand start ...hangs here...
/var/log/shaman.log you can see the following error:
19-10-13 09:31:10.177 shaman: Local lock (.shaman/md.e6443b8f610a4f10/lock) already exists, try to reopen
The issue is recognized as a product bug PSBM-23156: there is a very big lease timeout on the lock file, belonging to the local node.
The issue has been fixed in PCS 6.0 update 5.
Manual solution: set the shaman lock timeout:
~# shaman set-config LOCK_TIMEOUT=60
