Hi all, I'm exploring the possibility to create a shared storage cluster using software raid (mdadm).
The idea is to have two normal servers each equipped with a SAS HBA (non-raid) with external SAS connections (e.g. LSI 9200-8e card) Then a dual controller JBOD which connects to both servers so that both servers can see all disks in the JBOD. Now the interesting part. I would like to create a software raid6 set (or multiple) with the disks in the JBOD and have the possibility to use the raid6 in an active/passive cluster. For instance create a raid6 set (md0) of 10 disks with the first 10 disks in the JBOD on server1. Create a filesystem on md0. Export the filesystem as NFS export (using exportfs). When doing a migrate of the resources it should stop exportfs, unmount filesystem, stop md0 (mdadm -S /dev/md0) on server1 and start md0 on server2 (mdadm -A /dev/md0), mount filesystem, start exportfs. Is this scenario possible and/or obsolete/superceded by another mechanism because I couldn't find anything regarding mdadm in combination with pacemaker except a fairly old raid1 resource agent which only seems to support raid1 sets. Any other recommendations in the scenario?
