RE: [Linux-cluster] Cluster aware RAID/LVM



Title: RE: [Linux-cluster] Cluster aware RAID/LVM

Classification: UNCLASSIFIED

You will be able to sleep at night if you just buy N (N > 1) cheap raid controllers, a common disk tower and hook N disk servers up to said disk tower in a cluster config and then set the cluster up such that one and only one is alive and exporting a GNBD (or NFS/SAMBA/ISCSI etc) device to your cluster of compute nodes. Or just buy a cheap turn-key SAN which is really nothing more than a disk enclosure with 1+ RAID controllers and a FC or AoE card. RAID should be left to the piece of hardware that is in direct physical contact with the drives.
