hi everyone
I have a group and I'm trying to colocate - sounds strange - order with
the group is not how I want it.
I was hoping that with colocation set I can reorder the resources - can
I? Because .. something, or my is not getting there.
I have within a group:
IP
mount
smb
IP1
and I colocated sets:
set IP IP1 sequential=false set mount smb
and yet smb would not start on IP1. I see resource are still being order
as they list.
Could somebody shed more light on what is wrong and group vs colocation
subject?
m. thanks

A group is a shorthand for colocation and order constraints between its
members. So, you should use either a group, or a colocation set, but not
both with the same members.
If you simply want to reorder the sequence in which the group members
start, just recreate the group, listing them in the order you want. That
If you're using pcs, you can change the order of resources within an
existing group with the "pcs resource group add" command and --before or
--after options. For example
pcs resource group add your_group IP1 --after IP
changes your group like this
IP
IP1
mount
smb
is, the first member of the group will be started first, then the second
member, etc.
If you prefer using sets, then don't group the resources -- use separate
colocation and ordering constraints with the sets, as desired.
