2 node cluster + iSCSI

[adam0x54]

I 've been following Proxmox for a while and I noticed the addition of iSCSI in version 1.4.
Am I going to need a clustered filesystem to run a 2-node cluster with iSCSI? I have a dedicated NAS and I export luns from it to the servers. The idea is to use kvm + iSCSI partitioned with LVM on a two-node cluster to do live migration.

Thanks,

Adam

no, use LVM instead.

Yes, you can simply setup an LVM storage using the iSCSI lun as base.

Yeah this was my plan. I think for a two-node cluster it will be ok since one 1 vm will be writing in a logical volume. What about if you add 2 more servers in the cluster though?

no problem. just add another node, the master will make sure that it works as you expect.

Whats the problem with that?

I was just wondering if I will need any clustered filesystem to prevent any iSCSI lun corruption. But I guess since I will partition the lun with LVM and create each vm in its own logical volume it will be ok. Only one server at the time will access the logical volume. I lost my main iscsi lun recently because of iscsi corruption thats why I was asking. Better safe than sorry
