scottdaI think we were just discussing using a call to nova to quiesce the system, but we don't have that ATM. So a live snapshot isn't guaranteed to work without manually stopping I/O somehow. Someone please correct me if I'm wrong.14:44
*** nicolasbock has quit IRC14:44

smcginnisjgriffith: Would make writing a unit test easier too. ;)14:48
scottdaeharney: Thanks, that's about what I thought. But *someday* we could add the call from Cinder->Nova to quiesce and that would be a better solution.14:49
eharneyscottda: we poked at it with assisted-snapshots, and elsewhere, a while ago, it's certainly doable14:49

DuncanTwaj334: scheduler overload, db overload, message queue overload are the three most likely, in that order18:57
*** xyang has joined #openstack-cinder18:58
DuncanTwaj334: In my experiments, the scheduler starts to struggle much about 100 cvol services, though it will depend somewhat on your hardware18:59
DuncanTwaj334: You can spin up tens of copies if not hundreds of the cvol service with the fake driver (or lvm with a small backing file per driver instance) on a single beefy node to test19:00
guitarzanwaj334: message queue open file limit is a real thing :)19:02
DuncanTguitarzan: sysctl can make that go away19:02
guitarzanhaven't noticed problems with the scheduler for sure though, although ours is running on decent hardware19:02
guitarzanDuncanT: ya, it's easily fixed, just a gotcha19:02
patrickeasthemna: yo, so as a side project while playing detective sifting through logs i built a newer version of multipath-tools from source and installed it on a fresh xenial node19:03
hemnaoh?19:03
patrickeasthemna: and it is OK with getting multipath -r calls, has some issue with multipath -l <device>, which looks to be fixed even later on19:03
hemnadamn19:03
hemnaxenial just sucks19:03
*** raunak has quit IRC19:03
hemnaI've been hacking with xenial's libiscsi and it's broken19:04
patrickeasthemna: so a lot of the weirdness might be fixed... trying an even newer one (like almost tip of tree multipath-tools) in the background now to see if that has the multipath -l thing fixed19:04
guitarzanwaj334: we have had rabbit blow up when doing bad things to the network, although I don't know if that has anything to do with # of c-vols19:04
patrickeastoh crap, libiscsi too?19:04
hemnayah19:04
hemnaI built libiscsi from source and it's fine19:04
hemnaeven got the python wrapper to build19:04

patrickeastdoes that need to run as root?19:08

patrickeastoh man, too good19:08
patrickeastwell the pain was in packaging, right?19:08
hemnarefresh that url19:08
* patrickeast likes to think we can toss that over the fence to redhat/cannonical19:08
hemnayah something is major wrong with the packaged libiscsi19:09
hemnamissing symbols and shit19:09
patrickeasthmm maybe it was like a slimmed down build or something19:09
hemnarunning nm on the canonical build shows no symbols19:09
hemnarunning nm on the build from source, shows everything19:10
hemnacanonical's builds of libs seem borked19:10
patrickeastoh, so there is like different packages i think19:10
hemnayah, libiscsi-dev19:10
patrickeastsome have debug info and more verbose kinda compilations19:10
hemnalibiscsi219:10
*** lpetrut has joined #openstack-cinder19:10

hemnaand share it with others and see where to go19:11
patrickeastsounds like a good plan19:12

jgriffithgiven that it's Icehouse not sure what we could/would do anyway20:01
smcginnisjgriffith: The later comment was surprising to me, though makes sense.20:01
smcginnisjgriffith: That an LVM filesystem in a guest could get detached and discovered on the host.20:02

jgriffithsmcginnis: well I'm not sure that it's not already fixed20:03
jgriffithsmcginnis: we had a number of things around activate back in the Icehouse time frame, that I think most were cleaned up20:03
smcginnisjgriffith: A lot has changed since then.20:04
jgriffithsmcginnis: I'm not an expert on the activate/deactivate stuff though20:04
smcginnisGuess I'll mark as Invalid and ask to reopen if it's seen again.20:04
smcginnisBeing a little ruthless closing out some of these old ones.20:04
eharneymy first guess on that bug would be that it's breaking because something inside the container is attaching to the LV20:04
*** jungleboyj has joined #openstack-cinder20:04

jgriffithsmcginnis: eharney there's the activate issue with Magnum that hogbin points out he can't repro any longer20:06
jgriffithsmcginnis: eharney and there's the "I created an LV in the Instance and something weird happened"20:07
jgriffithsmcginnis: as you noted, I do think the second one warrants some looking20:07
