You should be aware that DRBD currently has no way to provide cross-device consistency. If you lose the replication link, one device will have lost it before the others. This may or may not cause inconsistency in a file system (or other data) spread over several DRBDs. If you have the choice, try to contain one filesystem within one drbd. -- : Lars Ellenberg http://www.linbit.com : : DRBD/HA support and consulting sales at linbit.com : : LINBIT Information Technologies GmbH Tel +43-1-8178292-0 : : Vivenotgasse 48, A-1120 Vienna/Europe Fax +43-1-8178292-82 : __ please don't Cc me, but send to list -- I'm subscribed
