| admin1 | my osa install sometimes gets Error Code: 2013. Lost connection to MySQL server during query in nova ... haproxy has: haproxy[3431076]: Connect() failed for backend galera-back: no free ports | 16:42 |
|---|---|---|
| admin1 | cat /proc/sys/net/ipv4/ip_local_port_range => 3276860999 | 16:42 |
| admin1 | ss --numeric --tcp state connected "( sport >= :$first_port and sport <= :$last_port )" |grep 3306 | wc -l => 28232 .. mostly timewait | 16:43 |
| admin1 | anyone faced this before and did any tweaks ? | 16:43 |
| admin1 | like reuse ports, or increased the number of ports | 16:43 |
| admin1 | default timeout is 60 .. checking what others set and if there is an issue to make it as low as say 10 seconds | 16:49 |
| admin1 | seems like gnocchi creating havoc :D | 17:09 |
| admin1 | i see haproxy has http-reuse .. checking if anyone else has used this before | 17:26 |
| moha7 | Hi | 18:05 |
| moha7 | jrosser: Since the Z release, is OVS the default networking backend in OpenStack Ansible? | 18:07 |
| jrosser | ovs will never be the default | 18:08 |
| jrosser | we will switch from linux bridge to OVN at some point | 18:09 |
| jrosser | do be aware that deployment projects release later than the openstack services so OSA has not yet made a release for Z | 18:09 |
| jrosser | moha7: don’t be too concerned about what the default is, we have users with all 3 different backends | 18:11 |
| moha7 | By the "default" I mean "the best practice selected by 'You'"! | 18:12 |
| jrosser | that’s not how openstack-ansible works | 18:17 |
| jrosser | it ships with “sensible defaults” and absolutely everything is configurable | 18:17 |
| jrosser | it is not a tool that makes all the decisions for you | 18:18 |
| admin1 | moha7, diff user cases prefer diff backends | 19:51 |
| admin1 | i have some clusters happy with lb , while some need ovs | 19:51 |
| moha7 | +1 | 21:03 |
