Hi The Raid1 resource agent that comes with LinuxHA was adapted to provide active/passive failover per MD raid device, so that only one node has an MD active, while the other nodes in your cluster can activate on failover. MD also now has disk-based bitmaps so that when a RAID is reactivated on some (other) node, only what's out of sync will be resynced.
MD Raid software is not cluster parallel, so the same s/w raid device can only be accessed by one node at a time, but you can have more than one software Raid active on a own node, with separate failover to other (with other Raids already active) Hth, Robert >>> Pawel Osiczko <[EMAIL PROTECTED]> 11/24/07 10:53 PM >>> Hello, I'm having problems coming up with a solution which would allow for a clustered RAID1 storage with 2 disks living on a shared bus attached to 2 HA cluster nodes. So, essentially, I need shared storage for the clustered nodes with caveat that RAID should be capable of being failed over from one node to another. Is such an animal possible? Seems like OCFSv2 and EVMS are not capable of that. Redhat CLVM/GFS holds some promise, but I haven't had a chance to evaluate it yet. Any ideas? BTW, I've seen ha resources in Linux HA such as RAID1 - what is that for? Thanks! --p PS For the sake of argument let's say I can't use DRBD 8-) _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems _______________________________________________ Linux-HA mailing list [email protected] http://lists.linux-ha.org/mailman/listinfo/linux-ha See also: http://linux-ha.org/ReportingProblems
