| 11:28:56 | lyarwood | everything looks fine in the domain | |
| 11:29:04 | lyarwood | the device is there and attached as a SATA cdrom etc | |
| 11:29:20 | lyarwood | it's just not there within the guestOS | |
| 11:29:21 | kashyap | lyarwood: Very good point; it's the CirrOS image | |
| 11:29:39 | sean-k-mooney | well the cirros image usess a ubuntu 18.04 kernel | |
| 11:29:44 | sean-k-mooney | so it will have sata support | |
| 11:29:49 | lyarwood | you would think | |
| 11:30:02 | lyarwood | don't they recompile the kernel now? | |
| 11:30:02 | kashyap | Yeah, don't assume. | |
| 11:30:07 | sean-k-mooney | im not | |
| 11:30:20 | sean-k-mooney | i have use it with sata before | |
| 11:31:00 | sean-k-mooney | although i dont know if i have used it with sata and q35 | |
| 11:31:17 | sean-k-mooney | i have used it with sata and pc | |
| 11:32:35 | sean-k-mooney | lyarwood: are you lookign at a gate failure by the way | |
| 11:33:13 | lyarwood | sean-k-mooney: yeah the tip of my q35 series switches nova-next over to using q35 and some tests that rely on config drive (device tagging etc) are failing | |
| 11:33:29 | sean-k-mooney | ah ok | |
| 11:33:42 | lyarwood | sean-k-mooney: have a local reproducer anyway and I can't see anything related to SATA in dmesg within the instance | |
| 11:37:19 | sean-k-mooney | ya its strang | |
| 11:37:23 | sean-k-mooney | i booted it too | |
| 11:37:29 | sean-k-mooney | so it boots fine with sata | |
| 11:37:36 | sean-k-mooney | but lsblk and blkid are empty | |
| 11:38:55 | lyarwood | f33 finds the device fine | |
| 11:39:07 | lyarwood | weird, I could make the cdrom bus host configurable? | |
| 11:39:13 | lyarwood | as a workaround | |
| 11:39:23 | sean-k-mooney | well its configurable via the image alredy | |
| 11:39:52 | sean-k-mooney | whats odd its ist not in /sys/block | |
| 11:40:50 | kashyap | [root@rawhide-1 ~]# dmesg | grep -i sata | head -1 | |
| 11:40:50 | kashyap | [ 1.724456] ahci 0000:00:1f.2: AHCI 0001.0000 32 slots 6 ports 1.5 Gbps 0x3f impl SATA mode | |
| 11:41:21 | sean-k-mooney | i dont see it in /dev either | |
| 11:41:54 | sean-k-mooney | kashyap empty | |
| 11:43:15 | lyarwood | I wonder if SCSI would be a better bus for this anyway | |
| 11:43:34 | kashyap | sean-k-mooney: Look for `dmesg | grep -i sata` | |
| 11:43:41 | kashyap | What gues did you boot? | |
| 11:43:41 | lyarwood | ah I guess we don't know if we have the controller setup | |
| 11:43:56 | sean-k-mooney | kashyap: i did and it gives nothing | |
| 11:44:06 | kashyap | What guest? | |
| 11:44:07 | lyarwood | yeah same for me with cirros | |
| 11:44:11 | sean-k-mooney | cirros | |
| 11:45:16 | kashyap | Right; my guest is Fedora ("Rawhide" - rolling) | |
| 11:45:51 | sean-k-mooney | yes which is not what we are trying to debug | |
| 11:46:12 | sean-k-mooney | its odd because im not seeing anyting in /dev | |
| 11:46:18 | sean-k-mooney | or /sys for the disk | |
| 11:46:36 | sean-k-mooney | im really confused how the root filestyem is currenlty mounted | |
| 11:47:02 | kashyap | sean-k-mooney: I was posting it for info; not saying Fedora is what we're debugging here | |
| 11:47:51 | kashyap | lyarwood: sean-k-mooney: I see some forums online say CirrOS does not support SATA interface | |
| 11:48:53 | sean-k-mooney | unless we use the vfat config driver format that woudl be a problem | |
| 11:49:33 | sean-k-mooney | we cant really assuem scsi will work and virtio-blk is not avalid for a cdrom | |
| 11:50:10 | lyarwood | sean-k-mooney: ah check /etc/modules | |
| 11:50:22 | sean-k-mooney | just deleted them to try scsi | |
| 11:50:45 | lyarwood | scsi should work but I think we can get sata to also work by updating /etc/modules | |
| 11:51:38 | sean-k-mooney | that woudl requrie cirros to be updated | |
| 11:52:03 | sean-k-mooney | given its botting it is able to use sata somehow | |
| 11:52:19 | sean-k-mooney | /etc/modules is just the set of addtional moduels to load | |
| 11:53:12 | sean-k-mooney | by the way why i said scsi isnt really an option is windows does not have teh virtio-scsi drivers by default | |
| 11:53:19 | sean-k-mooney | so we could not change the default to scsi | |
| 11:53:33 | sean-k-mooney | we chose sata becasue it shoudl work on all operating systmes | |
| 11:53:42 | lyarwood | is scsi == virtio-scsi? | |
| 11:53:51 | lyarwood | you have to set the model to virtio-scsi for that to be the case right? | |
| 11:54:01 | sean-k-mooney | yes you do | |
| 11:54:12 | sean-k-mooney | the other scsi contoller are all quite old | |
| 11:54:20 | sean-k-mooney | im not sure we would want to use any of those by default | |
| 11:54:31 | lyarwood | well at least Windows would support it then | |
| 11:54:34 | lyarwood | but yeah | |
| 11:54:58 | sean-k-mooney | im not sure if it would it might | |
| 11:55:07 | sean-k-mooney | using scsi works by the way for cirros | |
| 11:55:12 | sean-k-mooney | show up as normal | |
| 11:56:03 | lyarwood | not for me as the config cdrom drive | |
| 11:56:10 | lyarwood | so I think there's something still missing there | |
| 11:56:17 | lyarwood | I found https://bugs.launchpad.net/cirros/+bug/1715009 from a while ago | |
| 11:56:19 | openstack | Launchpad bug 1715009 in CirrOS "Missing modules for scsi cdrom config_drive in ppc64le" [Medium,Fix committed] | |
| 11:56:34 | lyarwood | so I wonder if there's additional things we need on x86_64 | |
| 11:57:02 | sean-k-mooney | so looking at /lib/modules/... | |
| 11:57:14 | sean-k-mooney | cirros hs sfcsi and virtio drivers | |
| 11:57:17 | sean-k-mooney | but not sata | |
| 11:57:52 | sean-k-mooney | it only has the virtio scsi drivers by the way | |
| 11:58:16 | sean-k-mooney | im guessing the init ramfs has the sata drivers | |
| 11:58:45 | sean-k-mooney | or it fell back to an in kernel driver | |
| 11:58:51 | sean-k-mooney | rahter then a module | |
| 12:02:37 | sean-k-mooney | lyarwood: by the way we have a bug with bfv | |
| 12:02:58 | sean-k-mooney | lyarwood: shocking i know but bfv does not select the correct bus when you use sata | |
| 12:03:04 | sean-k-mooney | it will use scsi instead | |
| 12:03:13 | sean-k-mooney | i fixed this years ago for non bfv | |
| 12:03:27 | sean-k-mooney | but it looks like it back or was never fixed for bfv | |
| 12:03:46 | kashyap | Sorry for my choppiness here. Struggling with something today. | |

| 12:26:48 | lyarwood | sean-k-mooney: sorry had to go afk, with hw_disk_bus=sata? | |
| 12:30:13 | sean-k-mooney | lyarwood: ya if you hw_disk_bus=sata with bfv on ussuri then you get scsi | |

| 15:36:43 | lyarwood | stephenfin: thanks for the review, would you mind if I hold off on that respin until the rest of the series has been looked at? ./me doesn't want to hammer CI | |
| 15:36:57 | stephenfin | yup, fine by me. Working through it atm | |

| 15:53:19 | kukacz | hi. having queens, nova disk with images_type=raw, when doing server resize I'm ending up with unbootable instance. I noticed that new (resized up) boot disk is being created as qcow, not raw. Is this a bug or am I rather missing some configuration detail? | |
