This is not possible, but as a workaround you can just touch a file in
the start script which is tracked by the monitor script.
Here is an example monitorscript:
#!/bin/sh
[ -f /var/VRTSvcs/lock/dummy.lock ] && exit 110
exit 100
Yeah, we thought about this too and actually implemented a very similar
solution, however this leads into troubles if you crash a node
as it will leave the lock file on the crashed node and when it comes back,
it'll find the lock file and report the application as online on the same node,
giving you a concurrency violation. We could use /tmp (or anything similar
memory based filesystem which always gets wiped out on reboots).
Or modifying the vcs startup script to remove all locks in the above directory
before it does the hastart.
Neither solution is very elegant, safe or convenient, so I was hoping there is
a better built-in solution available for this rather unusual problem.
Thanks,
Harald
