So I've found a solution! Thanks to "cc_Smart" <smart@xxxxxxxxxxx> for pointing back to tgt iSCSI target. The closest I had come before this was using iSCSI with the pSCSI backend in the kernel, but that seems to produce a memory leak that consumes all RAM ... some sort of infinite loop on initiator login? Going back to userspace tools did the trick for me, but I had to dig to find the right flags to give it. 1. First, find what /dev/sg device maps to the DVD drive # for dev in /dev/sg*; do sdparm "$dev" | grep '\[cd/dvd\]$'; done In my case, /dev/sg0 is the generic device for /dev/sr0 2. Create the iSCSI target as normal (including ACL/whitelist) 3. Create the iSCSI logical unit # tgtadm --mode logicalunit --op new --tid 1 --lun 1 --backing-store /dev/sg0 --device-type pt --bstype sg # tgtadm --mode logicalunit --op update --tid 1 --lun 1 --params removable=1 4. Log in on the initiator as normal I thought at first I was hitting another bug in tgtd, but it's just that the BluRay disc I was testing with only works in one of my two drives (despite the drives being identical models). ¯\_(ツ)_/¯ My /etc/tgt/conf.d file for 5 DVD drives (I should probably write some udev rules for by-id symlinks to sg devices): default-driver iscsi <target iqn.2007-03:dvdroms:frankie> bs-type sg device-type pt removable 1 readonly 1 initiator-address 192.168.9.9 block-size 512 backing-store /dev/sg0 backing-store /dev/sg1 backing-store /dev/sg2 backing-store /dev/sg4 backing-store /dev/sg5 </target> Have fun with this info. Or not :) Thanks all, Ben Klein On Wed, 24 Oct 2018 at 10:03, Ed L.
