21:15:54 mriedem "reverting the failed attempt"?
21:16:02 mriedem s/reverting/fixing/?
21:16:23 mnaser maybe in an ideal world we can collect more of the cases where finish_revert_resize fails and test those out *before* starting to revert the resize
21:16:24 artom Oh. You can't revert out of an ERROR, can you?
21:16:25 mriedem you could reset status to active and try another resize
21:16:41 mriedem no you can only confirm/revert a server in 'resized' status
21:16:43 mnaser no you cant revert out of ERROR, only RESIZE_CONFIRM i think
21:16:49 mriedem you can hard reboot / rebuild a server in ERROR
21:17:03 mnaser tbh if you're going to hand a tool this dangerous, you might as well as have people login to their dbs and edit stuff manually
21:17:13 mnaser but thats my drive-by 2 cents
21:17:13 artom Which *they do*.
21:17:19 artom Unfortunately.
21:17:37 artom And not only that, but we help them do it.
21:17:54 mriedem that kind of goes back to my original question - allowing only setting active or error in os-resetState - i wonder how many operators are manually changing status to something else to retry an operation
21:18:26 mnaser wait os-resetState lets you do more than active and error?
21:18:29 mriedem no
21:18:42 mnaser oo
21:18:47 mriedem in cinder it lets you reset volume status to just about any known volume status i think
21:18:53 mnaser yeah
21:19:05 mnaser tbh my workflow has always been "bring something back to as consistent of a state as it is"
21:19:16 mnaser and then use api afterwards
21:21:01 artom Whoa, "shards cells by hardware generation" is a thing?
21:22:54 mriedem you don't need to read the spec, i'm going to go back in my cave
21:23:45 artom mriedem, just curious, and procrastinating this downstream thing :)
21:23:57 mriedem feel free to read it if you want
21:24:08 mriedem it is quite masterful in it's word count
21:24:08 artom Yes. I'm a free man in a free country.
21:24:27 mriedem sorry *its i know efried is watching
21:24:43 artom Uh huh. "Masterful count" is exactly what I think of you ;)
21:29:37 mriedem i guess in the case of normal resize failures, there is stuff in the compute on restart that tries to clean that up,
21:29:51 mriedem which isn't as possible with cross-cell since it's orchestrated across 2 cells from the top
21:30:30 mriedem but on revert i think the idea is basically, best effort cleanup from the target and make sure the instance is mapped back to the source so if there is an error the user can work with it there on the source with the original flavor, since they were trying to revert in the first place
21:31:17 artom (This isn't really related or asked for, but I feel that if you're using cells to segregate hardware you're doing it wrong? Wouldn't that what hosts aggregates are for?)
21:32:22 mriedem what if you have 10K old hosts and 10K new hosts?
21:32:31 mriedem you want them all in the same cell with the same mq/db cluster?
21:32:36 mriedem but 2 aggregates?
21:32:46 mriedem you can certainly do aggregates, but cells is also for the scaling issue
21:33:19 mriedem cern also segregates by hardware type i believe,
21:33:23 mriedem and by vm/bm flavors
21:33:33 mriedem lots of ways to slice it up
21:33:48 artom Yeah, I'd understood that cells sharding was for scale
21:34:57 artom So if you want to scale different hardware generations/types, it'd be cells for scale, and then in each cell aggregates of hardware
21:36:00 artom So in your 10K example, it'd be 1K or whatever per cell, and 500/500 old/new hardware
21:36:19 artom But I guess that ignore the flow of time
21:36:49 artom You'll have set up your cells with old hardware, not necessarily leaving wiggling room to add new hardware
21:37:13 artom Man, I'm really good at this procrastinating thing
