[10:15] <Chipaca> hello all
[10:15] <Chipaca> is it known that the maas snap dumps core on install on 16.04?
[10:16] <Chipaca> https://pastebin.ubuntu.com/26415649/
[10:19] <roaksoax> Chipaca: did you install with --devmode ?
[10:20] <Chipaca> roaksoax: no
[10:22] <roaksoax> Chipaca: https://docs.ubuntu.com/maas/2.3/en/installconfig-snap-install
[10:22] <Chipaca> why are we telling people to install stuff with --devmode :-(
[10:23] <Chipaca> but, anyway, that answers my question; it's known broken. onwards.
[11:09] <roaksoax> Chipaca: because otherwise maas woudldn't work
[11:10] <roaksoax> there are blockers that prevent the maas snap (not in maas) from working in fully confined mode
[11:10] <roaksoax> so we have to use devmode
[13:17] <vogelc> roaksoax: We upgraded our prod to 2.3.0 last night and now we get out of memory errors on the region controller when someone restarts the region controller or does a refresh on the ui.  Thoughts?
[13:17] <vogelc> roaksoax: builtins.OSError: [Errno 12] Cannot allocate memory
[13:21] <roaksoax> vogelc: do you have more details than that ? e.g. regiond.log and process list, etc
[13:21] <vogelc> roaksoax: sure, I will get them posted to a paste bin
[13:33] <vogelc> roaksoax: https://pastebin.com/sBG42Grk
[13:34] <vogelc> roaksoax: We increased the memory on the vm to 24GB and it would still consume all the memory and kill the process.
[14:05] <roaksoax> vogelc: does a top or similar show what is utilizing cpu/memory ?
[14:16] <vogelc> roaksoax: https://pastebin.com/97cchLQ8
[14:16] <vogelc> roaksoax: that is top and syslog output.  I just issued a refresh in the web ui
[15:38] <xygnal> roaksoax: would appreciate what actions we can take to debug why vogelc and I are seeing this.   It's as if the system is queueing up load until memory runs out.  How do we see what 'load' is going on internally?
[16:25] <xygnal> roaksoax: listing nodes in webui takes a long time, and seems to stall at 500.  never finishes 'loading' status.
[16:27] <xygnal> roaksoax: if i refresh the page,  shortly thereafter twistd3 consumes all memory and is killed by kernel.
[16:27] <xygnal> within minutes
[17:42] <bladernr> is there a way to query maas via cli and determine what kernel version is available for each option in maas? (something that does "Show me the kernel verision installed by 16.04-hwe")
[18:00] <bladernr> ^^ I'd like to be able to easily determine exactly what version MAAS will install if I choose hwe vs hwe-edge (currently BOTH seem to be 4.13, but they often don't match up)
[18:07] <gunix> bladernr: what is the difference between hwe and hwe edge?
[18:07] <gunix> i know kvm vms work only with hwe ... but no idea what edge is
[18:08] <bladernr> hwe is the current supported HWE kernel, -edge is the NEXT one coming
[18:43] <ltrager> bladernr: there isn't a way to do it with MAAS however you could query apt which is where the kernel comes from
[18:43] <ltrager> bladernr: e.g apt-cache policy linux-image-generic-hwe-16.04-edge shows its 4.13
[19:53] <bladernr> ltrager, thanks, that'll work.  I was hoping for a MAAS Cli way to ask it about the things it's going to install, but that too works
[21:05] <mup> Bug #1532286 changed: Postgresql-9.5 breaks MAAS <MAAS:Invalid> <https://launchpad.net/bugs/1532286>
[21:38] <klj1218> I'm trying to create a custom curtin preseed file and I've noticed that if I include "system_id" for the {node} it fails to pick the file up... I have to use the "hostname" instead. This doesn't match the documentation.
