I would like to build a failover cluster with SuSE. It should be two machines, one running and one standby. Each machine should have its own disks with an "data" volume that should be mirrord in realtime between the machines. Can somebody guide me, what applikations should i use?
for the failover aspect, look at heartbeat. As for mirroring the data, having it going all the time when one's just a backup to the primary (which will be unlikely to fail anyway), but prolly rsync with some wrapper scripts would do the job, or you could maybe look into some form of network RAID
The machine(s) will be an e-mail/www/ftp server.
And for the actual applications, use your MTA/httpd/ftpd of choice (I would use sendmail/Apache/vsftpd, but it's up to you) -- James Ogley, Webmaster, Rubber Turnip james@rubberturnip.org.uk http://www.rubberturnip.org.uk Jabber: riggwelter@myjabber.net Using Free Software since 1994, running GNU/Linux (SuSE 8.2) GNOME updates for SuSE: http://www.usr-local-bin.org
