| kleini | Next issue with aarch64 compute node with 384 cores and 1.5TB memory: udev triggers make the machine's load rise to 800 and more. 12k memory nodes 784 udev workers serialized on kernel lock on memory subsystem. making even SSH login impossible. Solution is to limit udev workers with children_max. | 09:03 |

| noonedeadpunk | ouch, that sounds unpleasent as well | 11:19 |

| kleini | https://paste.opendev.org/show/b5XIgjryb3o1vSOV8lMZ/ <- my solution to the udev problem | 12:38 |
| noonedeadpunk | well, that can be automated for sure... I believe you should be even able to add that with a variable quite easily | 12:49 |
| noonedeadpunk | ye https://paste.openstack.org/show/ba0qczJbRSnpgArvV1Ra/ | 12:51 |
| noonedeadpunk | I'd assume you should have some separate group for arm hosts, so adding it to group_vars should work nicely | 12:52 |
| noonedeadpunk | potentially makes sense to do that by default though somewhere.... | 12:52 |

| kleini | that runs with setup_hosts, right? because setup_openstack and especially os_nova has this udev trigger. | 12:58 |
| noonedeadpunk | yes, it is | 13:03 |
| noonedeadpunk | but I think there is actually a way also to skip any trigger as well | 13:04 |
| noonedeadpunk | like with `load: false` | 13:04 |
| kleini | https://paste.openstack.org/show/by2ggD4cVNfGO56jckgN/ <- slightly corrected openstack_hosts_systemd_services. ExecStart needs to be cleared first and restart should happen. | 14:04 |
