[Linux-HA] Apache failover / renaming the binary

[Dominik Klein]

http://hg.linux-ha.org/dev/file/5072025b79b8/resources/OCF/apache

lines 516-518

another example of how to use exits codes incorrectly.

I'll commit a patch soon.

In your script: Make line 518 look like this (on all nodes!):
exit $OCF_ERR_INSTALLED

Then cleanup the resource or start the cluster from scratch and try 
again. Should fix it.

Regards
Dominik

This is really odd because the log states "All 2 cluster nodes are eligible to run resources." but then 4 lines further it says "ERROR: unpack_rsc_op:   Preventing apache_2 from re-starting anywhere in the cluster". I am using a very simple CIB with one virtual ip and apache grouped. If i stop apache manually heartbeat does restart apache fine. By the way can I configure it so that it does failover right to the other node if apache is stopped or fails? When manually stopping heartbeat the failover does work.
