Hi All

Trying to learn a bit of iscsi for may be a future project. I have a ubuntu server which is going to the the iscsi target and a proxmox both will connect.

I have read a few bits about using an image file or using lvm on the target. Being when proxmox connects you connect as iscsi and then create and lvm, I take it that I can use an image file on the Target as lvm will be taken care of by proxmox. Would this be correct?

Thanks

My knowledge of iscsi is intermediate and mostly on rpm based OSs. You can share a block device (such as an unused LVM partition), fileIO (essentially a chunk of space reserved on a big file),pscsi or ramdisk storage over the ethernet which would emulate a scsi device for the iscsi initiator.

I do not understand what you mean by "an image file on the target", but you are free to create a large enough file (as per your requirement), name it whatever you want (even image.iso ) and you should be able to share it from your iscsi target (ubuntu) using fileIO.

Once the initiator(proxmox) detects it as a scsi device (it should report as a new disk such as sdb/sdc/..sdN, check in dmesg), you are free to treat it the same way (invoke fdisk, make partitions, create PV-VG-LV, create filesystem, make a mountpoint).

Iscsi devices are advised to be mounted on the initiator with "_netdev" option. Give it a shot and let us know.

Just think if ISCSI as a hard drive attached in most cases.

A remote system would have to have the ability to use any resource. Then it can use the iscsi drive like any normal drive. You will have to partition and format it. ISCSI is only the transport much like sata is. (except over network)
