iSCSI

[frantek]

Hi,

I try to test iSCSI. I've created a target and volume on my Synology box and used the Proxmox webinterface to connect the iSCSI volume. What else do I have to do to be able to use it? My goal in the future is to use two Syonology boxes in HA mode and use iSCSI multipathing like I do it with Datacore and vmware.

TIA
Matthias

I see, I've to create a LVM group on top and multipathing has to be configured manually.

Next question: Is ist required to use LVM to make this work properly or can I also create a filsystem like XFS on the resulting disk device?

The goal is to have HA storage in combination with HA Proxmox.

NO !!! On a shared storage you must NOT use a simple file system (like XFS, EXT, ecc.).
There is a protection system to lock shared LVM in Proxmox, or you can use a cluster file system, but NOT a standard file system (on a multiple mount destruction is assured).

OK, thanks for the advice.

I've to configure multipathing manually. Is it OK to create LVM storage with the GUI on top of the resulting devie(s) with HA, as I do not create the iSCSI connection with the GUI.
