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. Regards Peter
