The main reason is that Linux-HA does not include a file system, so it doesn't have (nor need) any kernel components. In contrast, linux-cluster was built around a file system originally, so there are parts which necessarily need to be in the kernel (namely GFS & DLM). CMAN was in the kernel in the RHEL4 branch, but now is in userland (and plugs in to openais). I guess you could port GFS to FUSE if you wanted... *scratches head* -- Lon -- Linux-cluster mailing list Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
