Hi Florian, None, because dual-Primary and OCFS2 are utterly pointless for Apache and MySQL. Apache and MySQL can be easily built on single-Primary DRBD with a regular filesystem (ext3/4, XFS, you name it). I would like load-balancing and use typo3 which writes upon access to the filesystem

Hi, GlusterFS is _definitely_ easier to set up than dual-Primary DRBD with OCFS2, and also much harder to break. I'll give it a try. Thank you both for this hint. MySQL Cluster as in NDB? Or Galera replication? Or MySQL replication in dual-master mode (*shudder*)? Or MySQL on DRBD? As in
