mriedem | dansmith: re cross-cell resize poc v2 to be more aligned with normal resize flow, i've got a problem which i need confirmation, | 16:12 |
mriedem | i'm trying to do an early prep_resize type thing on the dest which will do the resize_claim which creates the migration context, | 16:13 |
mriedem | problem is, at that point, the instance records are only in the source cell db and the context is targeted to the source cell, even though i'm running this code on the dest host in the dest cell - but i don't think that will work because i recall that the targeting on the context is lost over rpc right? | 16:13 |
mriedem | so any db stuff on the dest host at that point will try to go to conductor in the dest and blow up b/c the instance doesn't exist in that db yet | 16:14 |
mriedem | it works in functional tests b/c of our CheatingSerializer fixture and the CellDatabase fixture defaults to cell1 | 16:15 |
dansmith | well, yeah, the targeting is lost over RPC, but that's not really your problem -- it's that you can't do things in the target db for a given instance until the instance is created right? | 16:15 |
dansmith | you need the resize-like pre-claim because of non-normal resources like numa stuff? | 16:15 |
*** erlon has joined #openstack-nova | 16:16 | |
dansmith | because I think we should be trying to minimize our dependence on old-school claims like that | 16:16 |
dansmith | where possible of course | 16:16 |
mriedem | well, that and the resize_claim creates the migration context, which i'm still not really convinced i need yet - but i could create the migration context in conductor outside of the resize_claim code if i do need it | 16:17 |
mriedem | but yeah, trying to align more with the existing resize flow per spec feedback | 16:17 |
dansmith | yeah | 16:17 |
dansmith | well, you can't create the migration context in condutor until the instance is created anyway right? | 16:17 |
mriedem | this wasn't a problem in the shelve poc b/c i didn't touch the target cell until after i'd created the db records there | 16:17 |
mriedem | i can create the migration context in the source cell db if i need it | 16:18 |
mriedem | and then mirror it over | 16:18 |
dansmith | ah, sure | 16:18 |
dansmith | if that works | 16:18 |
mriedem | the problem with the shelve poc then is i'm waiting a long time to do any claims in the dest | 16:18 |
mriedem | i.e. after snapshot and shelving in the source | 16:19 |
mriedem | which could be a long time for a big root disk | 16:19 |
dansmith | yeah, and even if you claim resources in placement you may not have the numa/cpu resources you expect | 16:19 |
dansmith | I guess with shelve you delay scheduling super late altogether, but with the more-like-resize case, you can't really reserve all the resources you need until you have an instance created there | 16:20 |
dansmith | so in the latter case, you _could_ go ahead and create the instance in the cell db right? | 16:20 |
dansmith | also, I know it's been a while, but I don't think I said "we shouldn't do this will shelve" I just said "some of these attributes are not ideal" right? | 16:21 |
mriedem | regarding scheduling, that happens the same either way (shelve or more-like-resize) | 16:22 |
mriedem | we don't go down the new conductor task route unless the scheduler picks a host in another cell | 16:23 |
mriedem | so for the more-like-resize option, i could create the db records early in the dest cell yet | 16:23 |
mriedem | *yeah | 16:23 |
dansmith | ah, right, right | 16:24 |
dansmith | I forgot that we don't do this unless the scheduler picks another cell | 16:24 |
mriedem | even with my shelve poc, i see that my early verify code won't work there either - because that's running code on the dest host in the dest cell | 16:26 |
mriedem | so likely either route is going to require creating the instance record and friends in the dest cell db early in the process | 16:26 |
* dansmith nods | 16:27 | |
mriedem | and then i likely have some split brain / db syncing that i need to do throughout which sucks but likely unavoidable | 16:29 |
dansmith | well, | 16:29 |
dansmith | didn't I say something about creating the instance in deleted state so we could avoid that? | 16:29 |
dansmith | I think you told me why that won't work, but I'm still paging this in | 16:30 |
mriedem | that's not really the sync issue i'm thinking of, i'm thinking of like, we create the record in the dest cell db, do the claim which creates the migration context, now if i need to sync that migration context back over to the source cell, i need to do that copy explicitly; likewise, if the source cell changes the task_state on the instance during the process (like resize does), then i might need to sync those changes back ove | 16:31 |
mriedem | the dest cell instance record as well | 16:31 |
dansmith | oh | 16:31 |
dansmith | yeah, I guess | 16:32 |

melwitt | o/ | 17:01 |
mriedem | dansmith: so i think i'm going to spend some time today updating the spec because the more i work on the code, the more down the rabbit hole i go and likely won't have the spec ready by the time i'm out next week - so my plan is basically get some kind of high level agreement on the spec knowing there will be dragons during implementation, and then i'll be ferreting out those dragons | 17:12 |
mriedem | i think i at least know enough to know some pros/cons of the shelve vs more-like-resize flow to list those as well | 17:13 |
dansmith | okay | 17:14 |
dansmith | we really need to get more input on it than just me though | 17:14 |
mriedem | yeah mel and kevin left some feedback as well, and was in line with yours | 17:14 |
dansmith | oh, okay I hadn't looked yet | 17:14 |
mriedem | john is probably next best to review this given his prior experience | 17:14 |
dansmith | that makes me feel better | 17:14 |
dansmith | yeah | 17:14 |
dansmith | ah I see melwitt's comments were a little more anti-shelve than my waffling | 17:16 |
dansmith | so that makes what you were saying earlier make more sense | 17:16 |
melwitt | well, how I feel is I think it's hard to be definitive about shelve vs not, as both approaches have their cons, those were my initial impressions reading through. it doesn't seem like there's a great answer here and I expect us to go ahead with whichever approach mriedem thinks will be cleaner based on all of the work he's done | 17:23 |
dansmith | mriedem: melwitt: I replied to a few comments from melwitt | 17:32 |
dansmith | melwitt: yeah either will be disruptive and tons of work for sure | 17:33 |
