Hi, i'm currently establishing a two node cluster. I have a FC SAN and two hosts. My services are integrated into virtual machines (kvm). The vm's should reside on the SAN. The hosts are connected to the SAN via FC HBA. Inside the hosts i see already the volume from the SAN. I'd like to store each vm in a dedicated logical volume (with or without filesystem in the LV). Hosts are SLES 11 SP4. LVM2 and LVM2-clvm is installed. How do i have to "switch on" clvm ? Is locking_type=3 in /etc/lvm/lvm.conf all which is necessary ? In both nodes ? Restart of the init-scripts afterwards sufficient ? And how do i have to proceed afterwards ? My idea is: 1. Create a PV 2. Create a VG 3. Create several LV's And because of clvm i only have to do that on one host and the other host sees all automatically ? Later on it's possible that some vm's run on host 1 and some on host 2. Does clvm needs to be a ressource managed by the cluster manager ? If i use a fs inside the lv, a "normal" fs like ext3 is sufficient, i think. But it has to be a cluster ressource, right ?
Thanks in advance.
