Tomo, List Please find three patches attached. 1, This allows creating a SBC device without any backing store. I.e. no media loaded yet. It automatially forces such devices to be removable==1 and online==0 (no media loaded) 2, Add a new option to SMC so that you can force a storage elemet slot to become Empty. 3, Now, This is the funky stuff this has all been leading up to: Add documentation/script to create a SBC jukebox. This jukebox (when used ontop of BTRFS) can take snapshots of a different file (a file used to be exported as a normal SBC LUN thought a different target) that file can be snapshotted regularely via a cronjob. All x most recent snbapshots are then exported via a dedicated snapshot-target when an initiator can attach, pich which nsnapshot it wants to use (using MTX) and then access the content of the snapshot. i.e. You export a SBC LUN to an initiator. Then you use this snapshot script to create regular snapshots of that SBC device. These snapshots are then exported with a mediachanger through a different target to different initiators. Those other initiators can now access these point in time snapshots of the production LUN. regards ronnie sahlberg -- To unsubscribe from this list: send the line "unsubscribe stgt" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
