So assuming I won't do rm -rf /gluster-filesystem, it should be quite safe. And it too needs twice the disk space, since it's replicated with glusterfs on both servers. However, I'm of course open to better alternatives. I'm running Debian Lenny, which ships with Cyrus 2.2.13 - not sure if Cyrus replication is possible there? I'd like to stick with distro packages, but if a newer Cyrus version provides features which let you do HA without too much hackarounds, I'll consider upgrading. -- Tomasz Chmielewski http://wpkg.org ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
