Hello,
I am trying to understand if and how it's possible to use FreeNAS with this FC configuration to provide storage to multiple Proxmox PVE hosts (or any host for the sake of discussion) without worrying about data corruption.
My configuration is as follow:
FreeNAS Setup:
1. Dell PowerEdge 2950 Server, Qlogic QLE2462 (qty 2)
2. Dell MD1000
3. Two zvolumes, mapped to two separate iSCIS extents.
Host setup:
1. HP Server with Qlogic QLE2462.
I have connected server (A) with point-to-point, followed the instructions at the top of this post, and I have working FC storage to my host from FreeNAS. Great! Now I want to setup server (B), same configuration, provide storage via FreeNAS / FC. This is where I am confused.
Server A and Server B both see the same iSCSI target when I go into the QLogic bios settings. Also, I notice that to the QLogic HBA sees each extent as a LUN. I am unsure of how to provide LUN1 to Server (A) and LUN2 to Server (B) when it's all visible to both.
Doesn't that create a risk of file corruption, even if I only mount one LUN (i.e. LUN1) to one physical host (i.e. Server A.) ..? My end goal is to be able to setup separate zvolumes for each server, all of the same FreeNAS box.
Side question to that last statement: assuming there is a way to accomplish all this, would i be better carving out separate zvolumes for each physical host, or having one large zvolume avail (somehow, if it's safe from corruption) to all physical hosts?
Thank you very much in advance!
