Description

Hi,

DragonFly does not detect disks when running on GCE, the virtio-scsi controller is detected tho.

Here are there storage requirements that custom images need to fulfill [1]:

SCSI Storage Controller:
Virtio-SCSI Storage Controller
vendor = 0x1AF4 (Qumranet/Red Hat)
device id = 0x1004. Subsystem ID 0x8.
SCSI Primary Commands 4 and SCSI Block Commands 3 are supported
Only one request queue is supported
Persistent disks report 4 KiB physical sectors / 512 byte logical sectors
Only block devices (disks) are supported
The Hotplug / Events feature bit is supported

See attached dmesg with CAMDEBUG enabled and virtio debug set to level 5.

The following parameters were used for booting with the same result, no disk found:

CAM debugging options compiled in:

options CAMDEBUG
options CAM_DEBUG_BUS=-1
options CAM_DEBUG_TARGET=-1
options CAM_DEBUG_LUN=-1
options CAM_DEBUG_FLAGS="CAM_DEBUG_INFO|CAM_DEBUG_TRACE"
options CAM_MAX_HIGHPOWER=4
options SCSI_DELAY=8000 # Be pessimistic about Joe SCSI device

loader.conf has the following tunables:

dm_load="YES"
vfs.root.mountfrom="ufs:da0s2a"
hw.vtscsi.debug_level=2
hint.ehci.0.disabled=1
hint.xhci.0.disabled=1
