hi there,

I'm setting up an iSCSI server on Trixie. My plan is to export a block device with memory caching enabled for both reads and writes. Unfortunately, no matter what I try, targetcli always shows write-thru mode (for block devices). is there any way to change this? Different software?

Thanks in advance for any help
Greg

Hello,

I know nothing about iscsi, but the RedHat doc has a chapter showing how to create a read-only target:
