The raw-disk-with-object, osd-with-metadata-device, and pvc canary jobs used loopback devices to supply an extra block device beyond the single spare disk a GitHub runner provides. Loop devices behave differently from real block devices -- Rook gates them behind ROOK_CEPH_ALLOW_LOOP_DEVICES and special-cases them in the OSD daemon -- so exercising core scenarios on them is less realistic than using real SCSI disks. Provision the extra device(s) over iSCSI (LIO) instead, reusing the existing create_extra_disk helper: it now creates N LUNs, the new find_extra_block_devs and find_second_block_dev helpers enumerate them, and deploy_cluster gains a two_raw_disks mode. The three jobs now run entirely on real disks, and the canary CI no longer creates loop devices or relies on the loop-device test helpers. Signed-off-by: Joshua Hoblitt <josh@hoblitt.com>
