Re: Init script for multiple postmasters

Hi,
I'm trying to set up two postmasters on a two-node redhat cluster.
Instance #1:
pg_data: /var/lib/pgsql/data
user: postgres
Instance #2:
pg_data: /var/lib/pgsql2/data2
user: postgres2
Since databases are managed by cluster manager I need two different initscripts. Unfortunately the script provided in the rpm uses the 'status' function which does not make difference between two groups of processes:
$ /etc/init.d/postgresql status
postmaster (pid 5320 5319 5318 5316 5314) is running...
$ /etc/init.d/postgresql2 status
postmaster (pid 5320 5319 5318 5316 5314) is running...
In this scenario the cluster manager cannot determine wether a single instance is running or down.
I'm going to modify initscripts and use a differente approach to probe postmasters status, but I'm not sure if this is good:
ps ax | grep postmaster | grep /var/lib/pgsql2/data2
ps ax | grep postmaster | grep /var/lib/pgsql/data
What would you suggest?
Thanks
Nicola
