Re: HA cluster

Sorry if this is a duplicate, but I haven't seen my post in the
archives.

That depends on what you mean with "HA cluster", I guess. What do you
want to do? What kind of systems are you doing failover for? Do you
want load balancing with that? What kind of systems do you want to
balance load on? Stateless web servers? Do you want weighting as well?

For example, heartbeat from linux-ha.org is in the ports system under
sysutils/heartbeat. I don't know if it's up to date with the version
at linux-ha, though, but the linux-ha web site says their system runs
on FreeBSD.

OpenBSD's CARP has been ported to FreeBSD if you want to do failover
for firewalls with pf.

There are many load balancers that can run on top of FreeBSD.

Re: HA cluster

I'll give a try to heartbeat. I want to failover NFS servers, and 
database servers. By now I'm running cman+rgmanager (RedHat cluster suite)

regards,
Jordi

Re: HA cluster

Thanks Peter,
I suppose I'll have to do some more work than just change the OS ;)

regards,
Jordi

confirm subscribe to freebsd-fdp <at> bg-freebsd.org

Hi! This is the ezmlm program. I'm managing the
freebsd-fdp <at> bg-freebsd.org mailing list.

I'm working for my owner, who can be reached
at freebsd-fdp-owner <at> bg-freebsd.org.

Oops, that confirmation number appears to be invalid.

The most common reason for invalid numbers is expiration. I have to
receive confirmation of each request within ten days. Also, make sure
the entire confirmation number was in the reply you sent me. Some 
e-mail programs have a habit of cutting off some of the reply address,
which can be quite long.

I've set up a new confirmation number. To confirm that you would like

   freebsd-cluster <at> freebsd.org

added to the freebsd-fdp mailing list, please send
an empty reply to this address:

   freebsd-fdp-sc.1194252046.llddipapccmkknbcafnc-freebsd-cluster=freebsd.org <at> bg-freebsd.org

Again, check the reply address carefully to make sure it is all included 
before you confirm your subscription.

Sorry for the trouble.
