[opensuse-factory] using your machine as an iSCSI target(server)
Has anyone tried and been able to setup their machine to server 1 or more iSCSI targets mapped to local generic disk space (perhaps contiguous file space, or an XFS-realtime mapped file)? I couldn't find any iSCSI rpms for a tgt (target or server), though is seemed more than one for client. I found a tgt package, but running it gives: tgtd --debug 3 -f (null): fcoe_init(214) (null) (null): fcoe_create_interface(171) no interface specified. tgtd: tgt_miscdev_init(352) Cannot open control path to the driver tgtd: main(342) No kernel interface It's startup script wanted to load a missing kernel module 'iscsi_tgt'. :^/ Any ideas? -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

No one uses tgt. Use lio, example: » modprobe tcm_loop » zypper in --no-r targetcli-fb » targetcli /> cd /backstores/ramdisk;
create name=r0 size=16M Created ramdisk r0 with size 16M. /> cd /loopback create Created target naa.5001405f8d695858. /> cd /loopback/naa.5001405f8d695858/luns create storage_object=/backstores/ramdisk/r0 Created LUN 0.

Ahh... may have to wait a bit until I get my local packages correctly mirroring a latest release.

Uh, yea, what's a WWN? and where would I find direction on how to export it via iscsi for those not quite as intuitive... ;^/ Thanks! -l -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

It's a shell with tabbing and not many commands. Also, google: http://linux-iscsi.org/wiki/ISCSI -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
