I just want to make sure that my understanding of resource groups is
correct before I proceed too far. Are the following true statements
regarding resource groups:
1. The order in which resource primitives are listed in a resource
group is the order in which they will be started?
2. The order in which resource primitives are listed in a resource
group is the inverse of the order in which they will be stopped?
3. Resource primitives in a resource group are started
sequentially, not in parallel?
4. Even if one of the primitives in the group fails to start,
subsequent primitives will still be launched?
5. Ordering constraints outside of the group are not applied to
resource group members?
For example, given the following resource group definition:
group HACMASTER HACMASTER-JOBFILE HACMASTER-PWFILE HACMASTER-JAVA
HACMASTER-SSHKEYS HACMASTER-EXT-IP HACMASTER-BAK-IP HACMASTER-COMM-IP
HACMASTER-STOR-IP \
meta target-role="Started"
The 8 resource primitives listed will always be started in sequential
order beginning with HACMASTER-JOBFILE and ending with HACMASTER-STOR-IP,
correct? Similarly when shutting down a resource group, the primitives
will be shut down in the reverse order, i.e. starting with
HACMASTER-STOR-IP, correct? I do not need to set any other ordering
constraints beyond listing them in order in the group, correct?
If I want resource primitives to be dependent on another primitive being
successful, I should use a resource set and not a resource group, correct?
Thanks,
Tony
