Hi, I'm trying to confirm whether DRBD + Heartbeat cluster can put up with the following scenario. (1) startup DRBD + Heartbeat Active node's role: Primary Standby node's role: Secondary (2) crash the meta-data call "dd" command on the both of Active and Standby node like this; They have internal meta-data on /dev/cciss/c0d0p6. # dd if=/dev/zero of=/dev/cciss/c0d0p6 count=100000 after that, nothing has happened. Active node kept running its service, and after stopping Active node, Standby node took over the service. This behavior is not a problem, but I just want to know whether DRBD can keep its meta-data on memory(?) if DRBD's role is Primary or Secondary. If I down the DRBD's resource and "dd" the meta-data, it seemed that meta-data was crashed, and I needed to recreate it. # drbdadm down all # dd if=/dev/zero of=/dev/cciss/c0d0p6 count=100000 # drbdadm up all ---> Failed! # drbdadm create-md all Thanks, Junko NTT DATA INTELLILINK CORPORATION
