I am going to get a storage server which will be
connected to my Xen hosts via iSCSI/Ethernet. I wish to use LVM for the
DomU disks. The storage server will have a RAID10 array, and 2 Xen
hosts will connect to this (Each will have a 50% share of the RAID10
array, space wise).
What is the best way to go about this? Should I:
a) Split the RAID10 array into 2 partition on the
storage server, and export 1 partition to each xen host, then let the
Xen host manage LVM?
b) Do all LVM stuff on the storage server and export
each LVM logical volume to the correct Xen hosts via iSCSI? Since each
host could have around 100 VMs on it, that's a lot of iSCSI exporting!
Any help is appreciated
