nope - heartbeat does no storage-management for you. There are 2 ways, you could take: 1) external Storage: 2) Shared-Nothing in your cluster 1) needs additional Hardware for Storage and this should also be HA, so this will end up in an additional Cluster :) 2) use drbd, ocfs2 on your nodes and your done. drbd replicates your "local disk" to other nodes (something like raid1-over-network). If you format this drbd-volume with a cluster-FS like ocfs2 you could write parallel from many nodes to this volume. > Or is it up to the web developers to ensure the content is in the correct > file systems? ;) > > Thanks, > B hth, Thomas _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
