shutdown of node shuts down VM

A part from /etc/init.d/rgmanager

Shouldn't umountiscsi.sh be listed under Required-Stop?

Anyway I can fix this?

I do not understand that fix: umountiscsis.sh umnounts file systems, and your VM does not use such file system.

wait, just found some code which deactivates iSCSI LVM Volumes. Did you set any 'LVMGROUPS' in /etc/default/open-iscsi?

wow, and found another bug - that script simply deactivates NFS volumes by default.

I guess I will add the dependency as you suggested.

Seems we stop open-iscsi before cman, but qdisk needs open-iscsis. Maybe you can try to add an iscsi dependency to the cman init script?
 
Re: [patch provided with fix] Re: shutdown of node shuts down VM

Hi Dietmar,

It seems to have fixed it. I still see lines in syslog like the following on start and stop:
Nov 14 17:38:15 esx2 pmxcfs[1809]: [quorum] crit: quorum_initialize failed: 6
Nov 14 17:38:15 esx2 pmxcfs[1809]: [quorum] crit: can't initialize service
Nov 14 17:38:15 esx2 pmxcfs[1809]: [confdb] crit: confdb_initialize failed: 6
Nov 14 17:38:15 esx2 pmxcfs[1809]: [quorum] crit: can't initialize service
Nov 14 17:38:15 esx2 pmxcfs[1809]: [dcdb] crit: cpg_initialize failed: 6
Nov 14 17:38:15 esx2 pmxcfs[1809]: [quorum] crit: can't initialize service
Nov 14 17:38:15 esx2 pmxcfs[1809]: [dcdb] crit: cpg_initialize failed: 6
Nov 14 17:38:15 esx2 pmxcfs[1809]: [quorum] crit: can't initialize service

Is this caused by the prior bug, and how can it be fixed?

We stop cman before pmxcfs, so those messages are expected (It is non-trivial to avoid them, sorry).
 
Re: [patch provided with fix] Re: shutdown of node shuts down VM

Ok. Just to be curtain. Quorum is establish perfect and messages flow between nodes when status change. I conclude this issue has been fixed:)
