capsalihi guys10:32
capsaliis there any official doc for postgres ha that works with maas?10:32
capsalibecause on the maas ha docs there is only a link to the postgresql website10:32
capsalifor the moment we are using two postgresql with built in master/standby replication (WAL)10:32
capsalion top of that we have two pgpool2 instances that handle the write requests, load balanced reads and the failover part10:33
capsaliwatchdog is active in pgpool2 with a VIP10:33
capsaliin regiond.conf the database is pointed to the watchdog VIP10:33
capsaliwe have around 200+ nodes that are mentained by maas10:33
capsalithe problem is that pgpool2 dies once a week for reasons i have yet to discover10:33
capsaliare there any special configs (e.g. max_conn, timeout, etc. ) that must be made in either postgres or pgpool ?10:33
capsalior is there a better approach in ha/failover for postgresql when using maas?10:34
roaksoaxcapsali: we are not opinionated about how to setup your postgress in HA10:39
roaksoaxcapsali: we have tested, however, hot standby with streaming replicaiton10:40
capsaliand did you use a virtual ip when connecting multiple region controllers to the db?10:44
capsalior did you connect them to the master psql server?10:45
roaksoaxcapsali: yeah VIP, but I dont think we load balanced reads10:58
capsaliroaksoax: keepalived or watchdog?10:59
roaksoaxcapsali: keepalived11:00
capsaliroaksoax: so i'm guessing you have manual failover when a disaster occurs right?11:00
capsaliroaksoax: do you use the defaults in postgresql.conf, besides the streaming replication changes?11:02
roaksoaxcapsali: we used the postgresql vcharm to deploy postgresql11:04

roaksoaxBraven: what version of django are you using ?14:43
Bravenroaksoax: So what might it be?14:43
roaksoaxBraven: to me sounds like a broken django or missing dependencies, or a non-supported version of django14:44
Bravenroaksoax: should I try to install it?14:44
roaksoaxBraven: what django version do you have running ?14:45

roaksoaxBraven: did you upgrade django and you started seeing this ?14:49

BravenWhat power type should I use with a VMWARE server20:02
Bravensorry VMWARE vitural machine20:02
brendandBraven, there should be just a vmware power type20:19
brendandyeah, there is. not really sure it could be more straightforward :)20:20
Bravenbrendand: I selected vmware option. Do you know what username \ password it needs?20:40
Bravenbrendand: because I am using my vCenter username pw21:00
brendandBraven, i'm not really sure, i don't have much experience using vmware21:14
brendandBraven, reading the code it's based on pyvmomi21:14
Bravenbrendand: I did install that package21:15
brendandBraven, have a google around i'd say - whatever is required to control it with pyvmomi will be what maas needs21:17
Bravenbrendand: I will google it . Thanks21:18
Bravenbrandand: Do you know what script MAAS is using to connect to VcenteR?21:32
brendandpyvmomi21:34
