capsali | hi guys | 10:32 |
capsali | is there any official doc for postgres ha that works with maas? | 10:32 |
capsali | because on the maas ha docs there is only a link to the postgresql website | 10:32 |
capsali | for the moment we are using two postgresql with built in master/standby replication (WAL) | 10:32 |
capsali | on top of that we have two pgpool2 instances that handle the write requests, load balanced reads and the failover part | 10:33 |
capsali | watchdog is active in pgpool2 with a VIP | 10:33 |
capsali | in regiond.conf the database is pointed to the watchdog VIP | 10:33 |
capsali | we have around 200+ nodes that are mentained by maas | 10:33 |
capsali | the problem is that pgpool2 dies once a week for reasons i have yet to discover | 10:33 |
capsali | are there any special configs (e.g. max_conn, timeout, etc. ) that must be made in either postgres or pgpool ? | 10:33 |
capsali | or is there a better approach in ha/failover for postgresql when using maas? | 10:34 |
roaksoax | capsali: we are not opinionated about how to setup your postgress in HA | 10:39 |
roaksoax | capsali: we have tested, however, hot standby with streaming replicaiton | 10:40 |
capsali | and did you use a virtual ip when connecting multiple region controllers to the db? | 10:44 |
capsali | or did you connect them to the master psql server? | 10:45 |
roaksoax | capsali: yeah VIP, but I dont think we load balanced reads | 10:58 |
capsali | roaksoax: keepalived or watchdog? | 10:59 |
roaksoax | capsali: keepalived | 11:00 |
capsali | roaksoax: so i'm guessing you have manual failover when a disaster occurs right? | 11:00 |
capsali | roaksoax: do you use the defaults in postgresql.conf, besides the streaming replication changes? | 11:02 |
roaksoax | capsali: we used the postgresql vcharm to deploy postgresql | 11:04 |
Braven | good morning | 14:32 |
Braven | roaksoax: Hello | 14:35 |
Braven | When I add a node to maas I gettting this error: "You cannot add messages without installing django.contrib.messages.middleware.MessageMiddleware" | 14:41 |
roaksoax | Braven: strange .... | 14:43 |
roaksoax | Braven: what version of django are you using ? | 14:43 |
Braven | roaksoax: So what might it be? | 14:43 |
roaksoax | Braven: to me sounds like a broken django or missing dependencies, or a non-supported version of django | 14:44 |
Braven | roaksoax: should I try to install it? | 14:44 |
roaksoax | Braven: what django version do you have running ? | 14:45 |
roaksoax | Braven: dpkg -l | grep django | 14:45 |
Braven | roaksoax: https://paste.ubuntu.com/23475913/ | 14:46 |
roaksoax | Braven: what version of MAAs are you running ? | 14:47 |
roaksoax | ah nevermind | 14:47 |
roaksoax | maas 1.9 | 14:47 |
Braven | braven: yes | 14:47 |
Braven | opps | 14:47 |
Braven | roaksoax Yes, I am running 1.9 | 14:47 |
roaksoax | strange | 14:48 |
roaksoax | Braven: never seend that beofre, I wonder if this is due to the security fix that landed in django 15 days ago | 14:49 |
roaksoax | Braven: did you upgrade django and you started seeing this ? | 14:49 |
Braven | roaksoax: We update Maas last friday | 14:49 |
Braven | roaksoax: restarting the apache service on the MAAS server fixed the probably. | 15:18 |
Braven | Is there a doc for adding VMware vm to MAAS? | 17:02 |
=== zz_CyberJacob is now known as CyberJacob | ||
Braven | ?? | 18:01 |
Braven | What power type should I use with a VMWARE server | 20:02 |
Braven | sorry VMWARE vitural machine | 20:02 |
brendand | Braven, there should be just a vmware power type | 20:19 |
brendand | yeah, there is. not really sure it could be more straightforward :) | 20:20 |
Braven | brendand: I selected vmware option. Do you know what username \ password it needs? | 20:40 |
Braven | brendand: because I am using my vCenter username pw | 21:00 |
brendand | Braven, i'm not really sure, i don't have much experience using vmware | 21:14 |
brendand | Braven, reading the code it's based on pyvmomi | 21:14 |
Braven | brendand: I did install that package | 21:15 |
brendand | Braven, have a google around i'd say - whatever is required to control it with pyvmomi will be what maas needs | 21:17 |
Braven | brendand: I will google it . Thanks | 21:18 |
Braven | brandand: Do you know what script MAAS is using to connect to VcenteR? | 21:32 |
brendand | pyvmomi | 21:34 |
brendand | not a script, it's using that python library | 21:35 |
=== spaok_ is now known as spaok | ||
Braven | Brendand: I figure it out. I was trying to connect to the host not the vCenter. | 22:40 |
