I have 4 servers each with their own harddrive. I would like to setup gfs so that each can read/write to their local harddrive and the data synced to the other 3 harddrives. My original idea was to export all 4 harddrives with a network block device like iscsi/gnbd/nbd and then use md software raid1 on top of those but I've heard that this is a bad idea as md is not cluster aware. I also found drbd but it only supports 2 harddrives. Are there any available solutions for doing a 4 way mirror like I am looking for? Basically a network raid 1 across 4 harddrives on 4 separate systems. Thanks, Jon. -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
