| 17:00:57 | sean-k-mooney | i think we used to do this in the intel nfv ci | |
| 17:01:16 | sean-k-mooney | to reduce memoryusage because we were deploying with ovs-dpdk | |
| 17:01:23 | bauzas | for the temp tables, well that's less of a concern | |
| 17:01:40 | bauzas | iirc, if the tmp tables aren't large enough, this just goes on disk | |
| 17:01:53 | sean-k-mooney | no it was for the pools as well | |
| 17:02:01 | bauzas | so this becomes an I/O performance question | |
| 17:02:11 | sean-k-mooney | right i dont think it will be in our usage | |
| 17:02:29 | sean-k-mooney | we will see but i would prefer to see by turning this on by default in all the jobs | |
| 17:02:34 | sean-k-mooney | and seeign if we see any regressions | |
| 17:03:25 | bauzas | so, I double-checked and yeah the pools are for caching | |
| 17:03:32 | sean-k-mooney | yep | |
| 17:03:46 | bauzas | so in case the pools aren't large enough, this is just a disk io performance concern as well | |
| 17:03:53 | sean-k-mooney | both of result sets and quey execution plans i belive | |
| 17:04:18 | sean-k-mooney | bauzas: yep but we are already swappign to disk in several jobs | |
| 17:04:30 | sean-k-mooney | if we can reduce that it likely will improve perfromce over all | |
| 17:04:57 | bauzas | yeah, now I refresh my mind | |
| 17:05:01 | sean-k-mooney | basically what im saying is any perfromance hit form the mysql turning will likely be offset by reduced memory pressure over all | |
| 17:05:13 | bauzas | I remember we can call the innodb engine to get the performance metrics | |
| 18:11:26 | auniyal | this :( https://zuul.openstack.org/status#864055, its always fail on gate | |

| 10:20:35 | songwenping | sean-k-mooney: hi, i have two same gpus on one host and want to passthrough two vms, my passthrough_whitelist is set {'vendor_id':'10de','product_id':'1e04'} and alias is set {"vendor_id":"10de","product_id" : "1e04","name": "gpu"}, but i can only create one vm, the other failed with no valid host filetered by pcipassthroughfilter. so how can i make the configuration? | |
| 10:31:06 | bauzas | songwenping: which version and what says the filter ? | |
| 10:33:54 | songwenping | Rocky and PciPassthroughFilter: (start: 1, end: 0) | |
| 10:34:52 | sean-k-mooney | that should work | |
| 10:34:55 | bauzas | you would need DEBUG levels | |
| 10:35:09 | sean-k-mooney | songwenping: can you check the pci_devices table in the nova cell db | |
| 10:35:14 | sean-k-mooney | and make sur eboth are there | |
| 10:35:30 | sean-k-mooney | songwenping: you alos need to make sure xorg (if its installed) is not using one of the gpus | |
| 10:35:41 | sean-k-mooney | i.e. make sure they are both bound to vfio_pci | |
| 10:35:57 | songwenping | pci_devices table has two gpu record. | |
| 10:36:04 | sean-k-mooney | ok | |
| 10:36:20 | sean-k-mooney | and one is aviable | |
| 10:36:36 | sean-k-mooney | and the other asigned to the first vm | |
| 10:36:43 | bauzas | sean-k-mooney: that's a scheduler filter issue | |
| 10:36:51 | bauzas | so not related to the driver | |
| 10:36:53 | sean-k-mooney | ya it is but i dont think its a bug | |
| 10:37:13 | bauzas | yup | |
| 10:37:15 | sean-k-mooney | bauzas: right i jsut mentioned the driver for after this is fixed | |
| 10:37:30 | bauzas | anyway, I need to get off the keyboard | |
| 10:37:33 | songwenping | i am opening the debug level to get more info | |
| 10:37:35 | sean-k-mooney | songwenping: are you useing numa by the way | |
| 10:37:48 | sean-k-mooney | i.e. cpu pinning or hugepages | |
| 10:37:49 | songwenping | no using numa | |
| 10:37:54 | sean-k-mooney | ok | |
| 10:38:36 | sean-k-mooney | if you can pastebin the entires for the pci_devices and debug secduler logs we can take a look | |
| 10:39:09 | sean-k-mooney | i just want to look at the 2 for the gpu | |
| 10:39:38 | sean-k-mooney | its odd that one worked and the other is failing | |
| 10:39:47 | sean-k-mooney | i would have expect both to fail or both to work | |
| 10:40:23 | sean-k-mooney | im wonderign what device_type is set to i assum type-PCI but it could be type-PF depending on the type of gpu | |
| 10:55:25 | songwenping | sean-k-mooney,bauzas: that's becuase the disk is not enough, i use the local disk. thanks a lot. | |
| 10:56:21 | sean-k-mooney | huh the pci filter shoudl not be | |
| 10:56:36 | sean-k-mooney | oh the disk filter elimiated the host that had the free pci device | |
| 10:56:49 | sean-k-mooney | and then the pci filter elimiated the remaining host because there was not a free gpu there | |
| 10:56:53 | sean-k-mooney | ok makes sense | |
| 10:57:13 | songwenping | yes, the filter error is mislead. | |
| 10:57:38 | sean-k-mooney | ya you bacially need to look at the set of all filters when debugging it | |
| 10:57:48 | sean-k-mooney | not just the last one that elimiated the final hosts | |
| 10:58:28 | songwenping | yeah the debug info is very useful. | |
| 10:58:55 | sean-k-mooney | some operators run with dbug on all the time for what its worth | |
| 10:59:05 | sean-k-mooney | you might now want it enabeld on all the services | |
| 10:59:14 | sean-k-mooney | but i like having it on for the scheduler at least | |
| 10:59:31 | bauzas | ok gtk | |
| 10:59:52 | sean-k-mooney | there is an argument to be made for moving those specific logs to info level | |
| 11:00:15 | sean-k-mooney | we didnt in the past because it can be a bit noisy but its a trade off | |
| 11:11:11 | Uggla | sean-k-mooney, gibi, bauzas Hi, is the a way to disable a flag set with self.flags(...) ? | |
| 11:15:41 | sean-k-mooney | Uggla: well you can just set it to what you want but if you mean you want to revert it to the unset state then you likely need to do thave via oslo | |
| 11:16:20 | sean-k-mooney | https://docs.openstack.org/oslo.config/latest/reference/locations.html | |
| 11:16:33 | sean-k-mooney | so flags i think is calling set_override | |
