|---|---|---|
| svenkat | all : I added Unit test code for 460672. Please review. | 12:55 |
| thorst | svenkat: is there a reason you aren't using the original nova bug/ | 12:56 |
| svenkat | thorst: i followed what Madhavi did. let me look | 12:57 |
| thorst | it was my comment 40 minutes before Eric's | 12:57 |
| svenkat | thorst: you mean use 1531022 instead? | 12:57 |
| svenkat | oh ok.. | 12:57 |
| svenkat | let me resubmit with third patchset | 12:58 |
| thorst | just update commit message. | 12:58 |
| openstackgerrit | Sridhar Venkat proposed openstack/nova-powervm master: Deallocate network on reschedule https://review.openstack.org/460672 | 12:59 |
| svenkat | done. | 12:59 |
| *** smatzek has quit IRC | 13:05 | |
| *** smatzek has joined #openstack-powervm | 13:05 | |
| efried | svenkat Add nova-powervm to the "affects project" list of 1531022. | 13:14 |
| svenkat | sure. | 13:15 |
| efried | I left a comment on the commit message. | 13:15 |
| efried | Just those couple tweaks and we're good here. | 13:15 |
| efried | Oh, and mark https://bugs.launchpad.net/nova-powervm/+bug/1686774 as a duplicate of the above. | 13:15 |
| openstack | Launchpad bug 1686774 in nova-powervm "During rescheduling VM temporarily holds additional IP addresses" [Undecided,New] | 13:15 |
| *** mdrabe has joined #openstack-powervm | 13:16 | |
| efried | svenkat I can do the LP paperwork if you like | 13:16 |
| svenkat | i added nova-powervm to 1531022 | 13:17 |
| efried | svenkat I'll mark the dup | 13:17 |
| svenkat | let me add it as duplicate to 1686774 | 13:17 |
| svenkat | oh ok.. thanks efried | 13:18 |
| svenkat | pls do. | 13:18 |
| efried | svenkat I think once you fix that space in the commit message, LP will also automatically post your change set to the bug. If it doesn't, it should be added manually. | 13:18 |
| svenkat | yes.. removing space. one moment | 13:19 |
| openstackgerrit | Sridhar Venkat proposed openstack/nova-powervm master: Deallocate network on reschedule https://review.openstack.org/460672 | 13:20 |
| svenkat | no changes in 1531022 so far.. | 13:22 |
| svenkat | I see it now. | 13:22 |
| *** jpasqualetto has joined #openstack-powervm | 13:28 | |
| efried | svenkat I don't | 13:28 |
| thorst | efried: not sure it will for nova_powervm | 13:28 |
| thorst | nova yes, not sure we have that function in nova_powervm | 13:29 |
| svenkat | on right side i see a section that says duplicates of this bug… and under that i see 1686774 | 13:29 |
| efried | Oh, yeah, I'm looking for the thing where it posts a comment in the bug with a link to your change set. | 13:29 |
| thorst | just manually change topic to the new bug? | 13:29 |
| efried | thorst Oh, I thought it was predicated on the Closes-Bug tag. | 13:30 |
| thorst | o maybe not | 13:30 |
| thorst | I could be wrong | 13:30 |
| efried | Anyway, none of that should hold us up merging the change set. But someone finding either bug needs to be able to backtrack to the change set somehow. | 13:30 |
| efried | svenkat Remove "Added unit test code" from commit message. | 13:31 |
| svenkat | ok.. | 13:31 |
| efried | I updated the topic | 13:32 |
| efried | but I don't think LP keys off of that. | 13:32 |
| openstackgerrit | Sridhar Venkat proposed openstack/nova-powervm master: Deallocate network on reschedule https://review.openstack.org/460672 | 13:32 |
| thorst | svenkat: you're planning on driving that fix into core nova as well? | 13:32 |
| thorst | because you're seeing this on ppc64 KVM as well? | 13:32 |
| thorst | (and none of it really seems to be ppc specific) | 13:33 |
| svenkat | yes. as we discussed yesterday. my idea is to default it to True instead of False. | 13:33 |
| efried | thorst Can we help Jay out? | 13:33 |
| thorst | efried: I saw Jays note...I'm swampped in PVC junk at the moment though :-( | 13:33 |
| thorst | I don't want to create an iSCSI volume from a raw image though | 13:34 |
| thorst | I think we want to deploy an image to nova ephemeral (SSP) | 13:34 |
| thorst | and then just attach an iSCSI volume at boot time. | 13:34 |
| thorst | that's the key test initially. | 13:34 |
| *** jay1_ has joined #openstack-powervm | 13:34 | |
| efried | thorst Okay. I don't even speak that language. I asked him to join IRC; maybe when tjakobs is on he can help out. | 13:34 |
| thorst | we can go from there. | 13:34 |
| *** jpasqualetto has quit IRC | 13:34 | |
| thorst | repeating for jay1_'s sake. | 13:34 |
| thorst | I don't want to create an iSCSI volume from a raw image though | 13:34 |
| thorst | I think we want to deploy an image to nova ephemeral (SSP) | 13:35 |
| thorst | and then just attach an iSCSI volume at boot time. | 13:35 |
| thorst | that's the key test initially | 13:35 |
| jay1_ | ok. | 13:35 |
| jay1_ | Deploy was successful when I tried today | 13:37 |
| thorst | with iSCSI volume attached? | 13:37 |
| jay1_ | my concern was to have ISCSI volume to try deploy, which I couldn't not do. | 13:39 |
| jay1_ | then I tried deploy from the image only | 13:39 |

| jay1_ | thorst: I will try Deploy again with public NW. Want to have subnet details for VLAN 1, which I don't have. Can you ping those details offline ? | 13:51 |
| *** mdrabe has quit IRC | 13:58 | |
| thorst | jay1_: The br-ex won't route traffic | 14:00 |
| thorst | so it won't work yet | 14:01 |
| thorst | I really just want us first to get to the point of deploying a VM and connecting an iSCSI volume | 14:01 |
| thorst | then I can go to the trouble of getting br-ex routed properly and what not | 14:01 |
| *** smatzek has joined #openstack-powervm | 14:01 | |
| jay1_ | thorst: sure, I just tried Deploy already and attached an ISCSI volume to it. but console is not opening for a VM. | 14:09 |
| thorst | jay1_: Hmm...I don't think I configured the console in the local.conf...or I know I didn't put the right stuff in to make it work | 14:10 |
| thorst | so just use mkvterm for now... | 14:10 |
| thorst | did the VM go active? | 14:10 |
| jay1_ | Yes | 14:11 |
| thorst | well that's something | 14:12 |
| jay1_ | trying to login to the VM with mkvterm | 14:13 |
| jay1_ | from the vm details it is not showing the attached volumes | 14:18 |
| jay1_ | from inside Ubuntu VM how to find the attached volumes ? | 14:21 |
| efried | jay1_ thorst I don't see any VSCSI mappings other than the boot disk and the cfg drive. | 14:22 |
| efried | I don't know squat about this, but I assume an ISCSI volume would be attached via a VSCSI mapping? | 14:22 |
| efried | Is that wrong? | 14:22 |
| efried | (no vfc mappings either btw) | 14:22 |
| jay1_ | I was assuming the same thing that volumes will be mapped to the host. I even created one iscsi host in the SVC with IQN, but even out of so many operations nothing has been mapped to that host entry. | 14:26 |
| efried | jay1_ I think tjakobs may be able to help with this, once he's online. | 14:29 |
| thorst | efried: yeah, its via a vscsi | 14:30 |
| thorst | efried: I'm not going to be able to look today and it seems tjakobs is out | 14:31 |
| thorst | but | 14:31 |
| thorst | if you have time...I think I can lead you the right way? | 14:32 |
| efried | thorst Does seroyer know how to do this? | 14:32 |
| thorst | efried: nope | 14:32 |
| thorst | the issue is most likely openstack | 14:32 |
| thorst | nothing else. | 14:32 |
| efried | oboy. | 14:32 |
| efried | Okay, lead away thorst | 14:32 |
| thorst | its not awful | 14:32 |
| thorst | 1) make sure you're adding volume connection tasks here: https://github.com/openstack/nova-powervm/blob/master/nova_powervm/virt/powervm/driver.py#L441 | 14:33 |
| thorst | if they are getting added...then the next pdb point is... | 14:33 |
| thorst | somewhere around here: https://github.com/openstack/nova-powervm/blob/master/nova_powervm/virt/powervm/volume/iscsi.py#L85 | 14:33 |
| thorst | sure would be nice to have log statements in here too... | 14:33 |
| *** jpasqualetto has quit IRC | 14:35 | |
| efried | thorst Okay, and jay1_ knows enough about how the deployment part works to get me started there? | 14:35 |
| efried | I've never done anything with volumes of any kind. | 14:36 |
| thorst | so, go through the UI | 14:36 |
| thorst | I know you hate it... | 14:36 |
| thorst | let me pull it up and show you the key in there. | 14:36 |
| efried | I don't hate the UI. Just haven't been using it much cause there's no way to say "no network" and I've been pretty much exclusively in tree for the recent past. | 14:38 |
| thorst | well, I hate that the ui likes to load sometimes and other times not at all | 14:41 |
| *** dwayne has joined #openstack-powervm | 14:47 | |
| *** jpasqualetto has joined #openstack-powervm | 14:48 | |
| thorst | efried: Images -> Pick one -> Launch | 14:48 |
| thorst | in Source... | 14:48 |
| thorst | Select Boot Source = Image (should be the image you have) | 14:48 |
| thorst | then I think 'Create New Volume = Yes' | 14:48 |
| thorst | the image should go to SSP for boot, and the volume you said to create should be iSCSI | 14:49 |
| thorst | I think. | 14:49 |
| efried | thorst Dig. | 14:49 |
| thorst | if that doesn't work...deploy a VM with create volume = False | 14:49 |
| thorst | then shut off vm | 14:50 |
| thorst | then attach a volume to powered off VM | 14:50 |
| thorst | may be easier that way | 14:50 |
| efried | jay1_ You wanna try ^^ first, before we get into pdb? | 14:50 |
| jay1_ | just triggered.. | 14:51 |
| jay1_ | launching image went to ERROr | 14:53 |
| efried | jay1_ What did you trigger? | 14:53 |
| efried | Did you try shutting off one of your existing VMs and attaching a volume to it? | 14:54 |
| jay1_ | Image >Ubuntu2g | 14:54 |
| jay1_ | trying the shutoff vm now | 14:54 |
| thorst | volume attach will surely fail unless you have it powered off or RMC active | 14:55 |
| thorst | I bet the image isn't RMC capable | 14:55 |
| jay1_ | RMC is active only from pvmctl o/p | 14:56 |
| jay1_ | thorst: attach volume option is not there for the shutoff vm from UI | 15:04 |
| thorst | Volume -> Manage Volume Attachments -> Select an Instance | 15:05 |
| thorst | just make sure the instance you select is powered off. | 15:06 |
| jay1_ | no error but can't see that attached to the vm from cli also. | 15:11 |
| thorst | so that's where we need to start inspecting logs/pdb's | 15:12 |
| thorst | efried: you able to do? | 15:12 |
| efried | thorst Yeah, multitasking, let me background these other things. | 15:13 |
| efried | Okay thorst jay1_ Looking at the code... | 15:16 |
| *** openstackgerrit has quit IRC | 15:17 | |
| jay1_ | efried:sure | 15:17 |
| *** k0da has quit IRC | 15:22 | |
| efried | thorst So this should be running down the `attach_volume` driver override, yes? | 15:25 |
| thorst | yeah | 15:26 |
| thorst | well, implementation, not override :-) | 15:26 |
| *** shyama has joined #openstack-powervm | 15:27 | |
| *** mdrabe has joined #openstack-powervm | 15:29 | |
| efried | jay1_ Added pdb stop. Restarting compute service... | 15:32 |
| efried | ugh, lots of unnecessary logging going here. Ima turn some of that off. | 15:33 |
| jay1_ | ok | 15:34 |
| efried | jay1_ Okay, let's do this. Try the volume attach again. | 15:35 |
| jay1_ | to the same shutoff vm right ? | 15:37 |
| efried | yes | 15:37 |
| efried | Okay, it's not even getting to our driver. | 15:38 |
| jay1_ | done , Attached the Volume "New_ISCSI" to the shutoff vm | 15:38 |
| efried | thorst Stand by for pastebin. | 15:38 |
| efried | thorst whoah, this doesn't sound right: Attaching volume c9f8c1ca-16cb-409a-a2d9-79e6cd1e0c1d to /dev/sdb | 15:39 |
| thorst | eh, OpenStack thinks it knows what dev its going to be. | 15:39 |
| thorst | it doesn't really? | 15:39 |
| thorst | I don't know why it puts in a device name | 15:40 |
| thorst | I think its maybe so that clients can rename it or something | 15:40 |
| efried | thorst You want me to pastebin or you wanna look on the system? | 15:42 |
| efried | pastebin is so ugly. | 15:42 |
| thorst | lets try pastebin | 15:43 |
| efried | thorst https://pastebin.com/EBU7FTUi | 15:48 |
| efried | oo, this is more readable: https://pastebin.com/raw/EBU7FTUi | 15:49 |
| efried | ...marginally. | 15:49 |
| adreznec | efried: you should use http://paste.openstack.org, no ugly ads/social media sharing junk/etc on that | 15:51 |
| efried | adreznec roger that. | 15:52 |
| efried | Do they have log format highlighting? | 15:52 |
| efried | Cause that'd be nice. | 15:52 |
