this looks interesting, any good manual about using DRBD? > About the cluster - you don't need to define any resources - > just have a cluster which is quorate to avoid data corruption while > accessing > the GFS on DRBD > > ok, so I only need the cluster with the 2 nodes and the gfs filesystem formated, for example like this: gfs_mkfs -p lock_dlm -t MyCLUSTER:mydata -j 8 /dev/sda1 When I have done this I can mount /dev/sda1 in both nodes as use it isn´t it?
