Hi All, I'm trying to understand from the sourcecode and from previous discussions on this list exactly which parts of a 'standard' LVM2 setup are 'unsafe' in an active/active GFS or OCFS cluster scenario. In other words, if I have a single LV, in a single VG, on a single PV, on a single LUN seen by two hosts via an FC SAN, with GFS or OCFS on top of it, and both hosts writing data, and no changes to the VG metadata at all, then where are the points of risk? >From what I can understand of the CLVM daemon, it is entirely concerned with serialising ~metadata~ updates, and writes to the LV are assumed to be safe as long as they are going through a cluster-aware filesystem on top? many regards, Darryl Dixon Winterhouse Consulting Ltd http://www.winterhouseconsulting.com -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
