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. -- MC, http://hack.org/mc/ From mc at hack.org Thu Nov 1 04:05:49 2007 From: mc at hack.org (Michael Widerkrantz) Date: Thu Nov 1 04:05:57 2007 Subject: HA cluster References: <4727BDD6.8060105@cesca.es> <47286EC1.4030608@cesca.es> Message-ID: <86tzo76zj3.fsf@tim.hack.org> Jordi Prats writes: > So there's no HA cluster for FreeBSD?

I try to imagine to use FreeBSD stuff as gmirror, ZFS, iscsi, CARP etc... it all does not sum up to something similiar - but it may be my lack of imagination only. NFSv4 is designed to support for replication and migration but I have no idea about the FreeBSD implementation status. I just find this old status report: http://www.freebsd.org/news/status/report-2006-01-2006-03.html#FreeBSD-NFS-Status-Report "FreeBSD NFSv4 server is pretty stable now and available via anonymous ftp. NFSv4.1 features are not a part of it yet and are not likely to happen until at least the end of 2006. Contact rick@snowhite.cis.uoguelph.ca for details." The sources for current only contains code for a NFSv4 client. To be fair I do not know about the Linux implematation either. A document last updated in March (http://wiki.linux-nfs.org/wiki/index.php/Server_state) predicts this implemented in 2.6.19. We have 2.6.23 by now but I cannot find it in the kernel changelogs.. > MySQL and PostgreSQL servers using RedHat cluster suite. As already pointed out there are replication solutions for postgresql and MySQL - they should work under FreeBSD in the same way as for Linux.
