Hi to all, Some questions about DRBDv9 (i'm really new to DRBD and DRBDv9 seems to be a major refactor): Let's assume a 3-node cluster a) should I use RAID or creating resources on raw-disks would be ok? b) can I use ZFS on top of DRBD ? c) what if I have to aggragate multiple resources to increase spaces ? Can I use LVM with something like this: pvcreate /dev/drbd0 pvcreate /dev/drbd1 vgcreate vg0 /dev/drbd0 /dev/drbd1 lvcreate ....... to create a single LV on top of 2 drbd resources ? d) what If node0.disk0 on resource0 will fail and node0.disk1 on resource1 don't? My LV spawning both resource will still work as expect but in a little bit slow mode as drbd has to fetch missing data (due to failed disk0) from one of the other peer ? e) AFAIK drbd is a network block device, to access this "block device" should I put an NFS/iSCSI/Whatever in front of it or are there something integrated in drbd ? (Like NFS inside Gluster) f) a 3node cluster is still subject to splitbrain ?
