Hello,
I’m in the process of design a solution replacement to a Veritas implementation and have to find similar functionalities, not
sure if this is doable in Red Hat Clutser:
We have a distributed application that runs in several servers simultaneously and that application must run in a cluster environment.
The summary is as follows:
1. Application has two different roles for the Servers, one we could call “Central Server” and the others “Collectors”.
2. Application has one Central Server and X Collector Servers.
3. Central Server + Collector Servers represents a set of servers that must be running all time and we want to implement
two sets in order to implement failovers between them.
4. First issue I have:
Application is installed in all servers at same location, let us say “/opt/app” and I want to monitor it in all them (i.e.:
different, separated, independent instances in separated servers).
In Veritas we had “fscentral” and “fscollector”, both with same device name and mounting point and that worked fine,
(of course, both resources were part of different service groups and running in different servers).
I tried to do the same here and got an error:
Any idea will be appreciated!!!5. Second issue I have:clurgmgrd[9374]: <err> Unique attribute collision. type=fs attr=mountpoint value=/optThen, I assume should be a different way to implement this resource? Notice that the number of Collectors is variable so I
clurgmgrd[9374]: <err> Error storing fs resource
can’t say “collector 1 will be mounted as /opt1” or “collector 1 will have volume name as vol1”.
How I can run the “service” “app collector” in more than one server simultaneously (in parallel)?
Again, the option to have “X” services for “X” Collectors is not a real option here.
Thanks
