fungi | er, a change needed for centos stream support | 16:01 |
tobiash | corvus: I'm currently investigating a potential bottleneck in nodepool. Profiling indicates that we might spend a significant amount of time in the NodeDeleter threads. | 16:04 |
tobiash | we have one thread for each node that is in deleting state and each one checks every two seconds if the node is gone | 16:05 |
tobiash | I could think about two approaches to improve this, the easy one would be to increase that interval to like 10-15s, another approach could be to streamline this into one thread that has a list of nodes to delete and periodically checks them all | 16:06 |
openstackgerrit | Merged zuul/zuul-jobs master: Temporarily stop running Gentoo base role tests https://review.opendev.org/c/zuul/zuul-jobs/+/771105 | 16:11 |
*** jfoufas1 has quit IRC | 16:19 | |
corvus | tobiash: when booting a server, there's an optimized code path inside of openstacksdk that gets the entire server list once and then notifies an individual thread when its ready. that code started in nodepool, then moved into sdk. but it doesn't look like there's similar code for deleting (because it's usually "fast enough" not to matter?) anyway, a third approach would be to see if we can somehow use the | 16:32 |
corvus | full server list cache to make that more efficient. | 16:32 |
corvus | tobiash: we're not using this method; i wonder if it would behave differently? https://opendev.org/openstack/openstacksdk/src/branch/master/openstack/resource.py#L2108 | 16:36 |
corvus | that looks like it might be the delete counterpart to the wait_for_server we use on creation | 16:36 |
clarkb | corvus: yes I think we expect server deletes to take only a few seconds | 16:36 |
clarkb | make the request, poll a small number of times then mark it done | 16:36 |
clarkb | whereas creates take 45-300 seconds or so | 16:37 |
corvus | clarkb: yeah, and generally that's beneficial because it lets us turn over servers quickly which helps avoid backlogs. so i think we should try to avoid the 'increase interval' approach -- it may trade one kind of backlog for another. (<-- tobiash) | 16:38 |
corvus | i haven't fully paged in all of the sdk code though, so i'm not certain about exactly where the caching is happening these days | 16:39 |
corvus | just mostly saying that's another avenue we should look at | 16:39 |
tobiash | I was always wondering if that caching actually works | 16:39 |
tobiash | is there a way to verify that? | 16:39 |
corvus | tobiash: maybe run with sdk request logging? | 16:40 |
tobiash | yeah, probably | 16:40 |
tobiash | the getServer we use atm seems to already use list_servers in the background | 16:41 |
corvus | i'm assuming that's where the benefit is; so if wait_for_delete does the same thing, then we might get a benefit | 16:42 |
tobiash | that's the profile I got with sigusr2: http://paste.openstack.org/show/801839/ | 16:45 |
tobiash | looking at the sdk code I believe that we're already using the optimized variant | 16:47 |
clarkb | ianw: thinking about the leaked /opt/dib_tmp contents from opendev's nodepool-builders I wonder if we should update nodepool to clear out that dir on startup similar to how zuul executors clean up their build dirs | 16:47 |
clarkb | ianw: in particular I think many of them are leaking when we restart nodepool-builder during the middle of builds as dib doesn't manage to clean up after itself in that situation. And we do that whenever nodepool docker image updates | 16:48 |
clarkb | maybe only clean it up if it is explicitly set in the nodepool.yaml config? | 16:48 |

clarkb | ianw: did you see my question/thought about having nodepool-builder clean up dib_tmp/ if it is configured in nodepool.yaml when the builder starts up? | 22:13 |
clarkb | ianw: I believe that if the builder (and dib) have stopped and are started again weshouldn't need any of the content there any longer | 22:13 |
ianw | clarkb: umm no but i agree it's probably helpful; although my worry would be about lost mounts | 22:14 |
clarkb | oh hrm | 22:15 |
clarkb | we'd be deleting things out from under mounts? | 22:15 |
clarkb | potentially anyway | 22:15 |
ianw | i mean dib should not be leaving mounts behind ... but that's not to say it wouldn't happen in practicality | 22:16 |
clarkb | ya, and I think the major source of these leaks is when we get a new nodepool-builder image and stop the processes and restart on the new image | 22:16 |
clarkb | dib doesn't seem to very gracefully handle that (though maybe we could tell docker-compose to do a more gentle shutdown, I think it uses sigint then sigkill if sigint doesn't work) | 22:17 |
clarkb | do you know if dib sets up its exit routines as signall handlers too? I wonder if that would go a long way to addressing this | 22:18 |
*** rlandy|biab is now known as rlandy | 22:20 | |
*** GomathiselviS has quit IRC | 22:22 | |
corvus | clarkb: i'm pretty sure it does and n-b relies on that | 22:31 |
corvus | so it *might* be the case that we "only" need to make the docker-compose -> nodepool-builder kill more graceful | 22:32 |
clarkb | aha | 22:33 |
clarkb | let me read some docker compose docs | 22:33 |
clarkb | "by default stop using sigterm" | 22:33 |
corvus | clarkb: just speculating -- it might even be the case that n-b is getting a signal that it's handling, and it kills dib gracefully, but that takes too long and compose kills it harder. | 22:34 |
clarkb | ya the wait before escalating from sigterm to sigkill is 10s | 22:35 |
clarkb | which is maybe not long enough to do file deletions and unmounts | 22:35 |
clarkb | I know the rm's I was doing yseterday took a while (its lots of small files and consequently stat'ing) | 22:36 |
