Zimbra NE Cluster on RHEL 5.3?

[minemonics]

It's possible setup Zimbra NE Cluster on Red Hat Entreprise Linux 5.3?

Old Posts on Zimbra Forums, tell this is not possible for problems with changes on cluster confs for RHEL 5.x

Anybody have Zimbra NE Cluster installed and running on 5.x RHEL?

Thanks!

This will be supported with the upcoming 5.0.18 release next week.

I have installed zimbra on Rehat 5.3 with ZCS 5.0.16 and works fine.

It does work but it's not supported yet.

Veronica,

Are you actually taking advantage of "CLUSTER" functionality on RHEL5.3 ?

I also installed ZCS 5.0.16 on RHEL5.3 and works great, but it's not working with "Red Hat Cluster Suite - Application/Service Failover".

Brian, Klug.. it sounds pretty cool, is it really comming supported on zcs 5.0.18 ? Why not on 5.0.17 ?

What do you mean by advantage of CLUSTER functionality ?

What error are you getting ? Did you do an zimbra application failover using zmcluctl script ? It would help if you show me the logs of error messages.

There's no 5.0.17.

Based on this bug (see below), RHCS 5 U3 is supported with ZCS 5.0.18.

For the most part cluster support will work in 5.0.16 on RHEL5. If you have a really long cluster service name then you may have issues with fail-over and/or upgrades, both of which are fixed with 5.0.18.

I see this bug on bugzilla related to Redhat 5.3 cluster Bug 39290 – Cluster fails abruptly with mcluctl failed (returned 1)

Excellent! Thank you Veronica, also thank you Brian and Klug.

With: "Are you actually taking advantage of "CLUSTER" functionality on RHEL5.3 ?" I mean, for instance, if you shutdown one node, the Zimbra services still working on the other one.. Application/Service Failover.

Great! There's already 5.0.18 released! I'm gonna have a try.
