[Ocfs2-users] data-replication AND rw access between clusternodes?
hello, got a short question about the function of the Ocfs(2)... I read the manual and the faq but still don't fully understand what exactly happens to the data :-/ As far as I understand the data stay physically on the harddisc of that node how produce/change it, only the "file-allocation-table" (or what o ever metadata) is exchanged between the nodes (and synced) and access is granted to all nodes via??? own Protokoll?? ssh?? Or are all data replicated to all harddisks in the cluster - like with drbd? What I'm lookin for is a filesystem that do exact that... replicate the data between the nodemembers (like drbd between two nodes) but (unlike drbd) grant all nodemembers read/write access... Any hints are welcome... TIA -- Psssst! Schon vom neuen GMX MultiMessenger geh?rt? Der kanns mit allen: http://www.gmx.net/de/go/multimessenger

OCFS2 requires a shared disk. Specifically, a shared disk that can be concurrently accessed by all nodes in the cluster.
