#openstack-nova - 2018-10-19
20:03:03 cfriesen ephemeral disks are supposed to last the life of the instance, right?
20:03:49 openstackgerrit Merged openstack/nova master: Don't persist RequestSpec.requested_destination https://review.openstack.org/610098
20:04:46 sean-k-mooney cfriesen: yes and know
20:05:04 sean-k-mooney cfriesen: i dont know if they are ment to be copied if we move the guest or not
20:05:31 sean-k-mooney cfriesen: they are ment to exsits for the life of an insntace on a singel host definetly.
20:06:14 sean-k-mooney cfriesen: resize is totally undefiend what happens. live/coldmigrate i think we copy them but havent checked that is just my intuition
20:07:13 sean-k-mooney cfriesen: similarly for shelve unshelve not sure we persit tiem. it might be driver specific
20:07:55 cfriesen sean-k-mooney: hmm...I think this wording in the compute API has changed since I looked at it: "Ephemeral disks may be written over on server state changes. So should only be used as a scratch space for applications that are aware of its limitations."
20:09:18 sean-k-mooney cfriesen: ya root disk will be perserved obviourly but adtionl epheral disk i think its totally up to the driver on what state chages they are preserved and when they are recreated
20:09:37 SteelyDan sean-k-mooney: I don't think any of those things are right
20:09:59 SteelyDan I don't think it's well defined at all, but the original assumption was that you couldn't even rely on them across start/stop cycles on your instance
20:10:26 cfriesen on the other hand, nova/doc/source/user/flavors.rst says "Ephemeral disks offer machine local disk storage linked to the lifecycle of a
20:10:26 cfriesen VM instance. When a VM is terminated, all data on the ephemeral disk is lost."
20:10:29 sean-k-mooney SteelyDan: from an api persectiv i would totally aggree.
20:11:18 sean-k-mooney cfriesen: yes but terminated is not stopped
20:11:30 cfriesen okay...I had been thinking that they were supposed to be preserved over everything except termination.
20:11:40 cfriesen but it sounds like that was incorrect
20:11:42 sean-k-mooney SteelyDan: i think the libvirt driver preservs the ephemeral disk in more cases then its required too
20:11:44 SteelyDan I'm quite sure they're not included in any snapshot, so not for shelve
20:11:49 SteelyDan sean-k-mooney: yes
20:11:56 melwitt you mean ephemeral in the flavor, not ephemeral like a normal local disk of any instance without ephemeral in the flavor
20:12:03 cfriesen melwitt: yes
20:12:09 melwitt gotcha
20:12:59 cfriesen okay. that simplifies my life, though not the end user's. :)
20:32:16 sean-k-mooney cfriesen: so as far as i can tell this is what determins what disks are migrated https://github.com/openstack/nova/blob/e2a39bb30f716c78af30d61efb3fb7526f9bdf6d/nova/virt/libvirt/driver.py#L7208-L7247
20:33:48 cfriesen sean-k-mooney: for live migration specifically
20:33:57 sean-k-mooney cfriesen: so for libvirt i think, that will include the ephermeral disk on live migration
20:34:01 sean-k-mooney yes
20:34:31 sean-k-mooney for rebuild/resize/cold migration i think we dont copy them
20:34:40 cfriesen the case I was looking into was a resize, followed by a resize-revert.
20:35:37 sean-k-mooney i can take a look. it makes sense that we copyt them on live migrate as that does not effect the life time of the instance as long as it succeeds
20:38:54 sean-k-mooney cfriesen: so for resize we copy the image here https://github.com/openstack/nova/blob/e2a39bb30f716c78af30d61efb3fb7526f9bdf6d/nova/virt/libvirt/driver.py#L8309-L8343 but i need to chec if the ephermeral disks are in elf._get_instance_disk_info(
20:40:34 cfriesen sean-k-mooney: don't waste time on my account, if the compute API says it can change, that's good enough for me.
20:40:41 sean-k-mooney cfriesen: it looks like its looping over all the disks too https://github.com/openstack/nova/blob/e2a39bb30f716c78af30d61efb3fb7526f9bdf6d/nova/virt/libvirt/driver.py#L7986
20:42:22 sean-k-mooney the code is very similar to the live migration code, they shoudl proably be refactored to gether but is also differnt enough that im not sure it does the same thing exactly
20:46:02 sean-k-mooney cfriesen: ya from an api persective it can. libvirt appears to keep them for cold and live migrate. i would assume they are not kept for rebuild,shelve and evacuate. i also think libvirt may be expanding the existing ephmeral disk in resize
20:47:34 sean-k-mooney cfriesen: the libvirt direver is specifclaly checking that we are not resizeing the ephermerl disk down https://github.com/openstack/nova/blob/e2a39bb30f716c78af30d61efb3fb7526f9bdf6d/nova/virt/libvirt/driver.py#L8268-L8275 implying that its not recreateing them but may be expanding them on resize
20:58:41 boden anyone heard about a "oslo_db.exception.DBNonExistentTable" cropping up across projects? Appears to have cropped up around 10/10 http://logstash.openstack.org/#dashboard/file/logstash.json?query=message%3A%5C%22oslo_db.exception.DBNonExistentTable%5C%22 and includes neutron, nova and others
21:15:39 mriedem boden: those are unit/functional tests,
21:15:47 mriedem and 10 days is as far back as logstash goes
21:15:54 mriedem so 10/10 is probably not really when it started
21:16:00 mriedem that's just how far back we have logs
21:16:13 mriedem it's showing patches in pike
21:16:39 mriedem and also shows up in successful job runs, so most likely unrelated to anything that's failing
21:17:52 boden mriedem perhaps that's the case for nova (I haven't dug there), but it doesnt appear to be the case for all others; there are valid failures
21:21:41 sean-k-mooney mriedem: boden is this realated why we have to loop for nova-manage out of interest
21:21:51 sean-k-mooney e.g. why wer did https://review.openstack.org/#/c/608091/
21:24:57 sean-k-mooney actully looking at the logs no this is unrealted
21:35:46 boden yeah my bad... I assumed nova was failing without digging... we have been getting this error on some other projects randomly; appears to be memory/resource related

10:38:49 sean-k-mooney adrianc: sure we could that said it is best to keep as much of these discussion on irc/ml/gerrit when it comes to the design side

10:41:53 sean-k-mooney ah i see you have
10:41:56 Dinesh_Bhor Hi All, Is there a recommended/official API rate limiter for Nova?
10:42:14 adrianc sean-k-mooney: agree(also commented on your spec), I have also a WIP POC, myself and moshele would like to have a short sync on the topic
10:44:06 sean-k-mooney adrianc: did you have a time in mind. i would like th discuss the spec/blueprint at the next nova team meeting to see if we can at least get the blueprint approved
