[12:13] <imranh> Can anybody help me? I have a sever with 2 interfaces with MAAS running, eth0 is 192.168.202.145/24 and is our main network, eth1 is 192.168.140.1/24. On MAAS i have eth0 set to unmanaged and it just gets dhcp in /etc/network/interfaces, eth1 is statically assigned in that file and under MAAS it does dhcp and dns. I have 5 servers plugged into the switch that eth1 is also plugged into. I can PXE boot, the server will start doing it's t
[12:14] <imranh> the network info it starts timing out grabbing "'http://169.254.169.254/2009-04-04/meta-data/instance-id'"
[12:16] <imranh> I've imported the 14.04 LTS amd64 images in maas
[12:17] <imranh> google leads me to https://bugs.launchpad.net/maas/+bug/1402861 but that doesn't really help
[12:21] <imranh> Am I better off asking this question elsewhere?
[12:36] <Razva> hi folks! in MAAS, if I go to Subnets, I see two fabrics: one for WAN and one for LAN (which I suppose it's ok). BUT when I go to Nodes and choose Subnets (from the left sidebar) I can see only the LAN IPs. isn't this wrong?
[12:44] <imranh> Fixed my problem, i ran dpkg-reconfigure maas-cluster-controller and changed the address from 192.168.202.145 to 192.168.140.1
[12:44] <Razva> imranh do you have any experience with setting MAAS?
[12:45] <imranh> Razva: none, sorry. I came on here tryng to setup my first cluster
[12:45] <Razva> hah, same here :))
[12:45] <Razva> do you see your public IPs in the Nodes -> Subnets (sidebar)?
[12:46] <Razva> because I can see only my LAN IPs, which is...weird
[12:46] <imranh> Razva: I've only just got node enlisting working in my enviroment, before abnout 2 minutes ago i couldn't get anything to enlist
[12:47] <Razva> need a hand?
[12:47] <imranh> Razva: Just got it going, need to go down to the server room to switch the machines on now
[12:48] <Razva> don't. use PXE
[12:48] <Razva> or at least you should :D
[12:52] <imranh> Razva: switch the machines on to pxe boot so they appear in the node list is waht i meant
[13:23] <Razva> oh, ok. from my experience using KVM or iDRAC will be REALLY helpfull. I've installed Ubuntu about 25 times in order to have a fully functional MAAS + Juju + AutoPilot + OpenStack installation.
[13:23] <Razva> here are my hints
[13:24] <Razva> 1) DON'T use RAID. just use plain disks, without any kind of raid
[13:24] <Razva> 2) rename your nics from em1 or eno1 or whatever to eth0 and eth1
[13:24] <Razva> ^^^ https://github.com/Razva/newbadmin/blob/master/device-management/nic-rename.sh
[13:25] <Razva> 3) install BIND Cache on your MAAS server if you want to deploy OpenStack or use any kind of networking stuff, as Juju is VERY bad sometimes at DNS (for reasons I cannot explain!)
[13:27] <imranh> Razva: cheers :)
[13:28] <imranh> I'm just waiting for access to the server room now
[14:09] <haasn> imranh: You don't have IPMI? AMT? Even wake-on-lan?
[14:10] <imranh> haasn: none of it is setup yet, fresh batch of servers
[14:10] <imranh> I don't even know the cpu model in them
[14:12] <imranh> All I know is that each one has: 56 threads, 128GB ram, 2x 320 drives, 2x 10G fiber cards and 1x 1G port

[14:30] <imranh> haasn: If only it was a little bit more quieter
[14:31] <imranh> haasn: Also the temperature difference a few steps can take is unbelieveable
[14:31] <haasn> The noise is so monotonous that it's as good as silence, the upside being that it also drowns out any possible audio distractions
[14:33] <imranh> haasn: :)
[14:45] <haasn> (Such as coworkers furiously yelling at you)
[15:33] <imranh> hmmm maas seems to think my servers are on when they are not...
[15:34] <roaksoax> imranh: wait for a minute or two till maas updates power states
[15:34] <roaksoax> imranh: maas doesn't do second by second power state update
[15:34] <roaksoax> imranh: otherwise your BMC may lock up
[15:35] <imranh> roaksoax: ok :)
[15:35] <haasn> It's funny when you think about it. The handbook for my servers contains an entire section on what to do if the BMC locks itself up (in various ways)
[15:35] <haasn> How are we, in 2016, programming work-arounds for BMCs locking themselves up?
[15:36] <roaksoax> haasn: that's due to the crappy BMC implementations out there!! You'd be surprised how bad sometimes they are :)
[15:36] <haasn> Imagine if Linux had code to throttle its floating point computations on intel processors to avoid locking up the floating point chip
[15:37] <haasn> It's just bizarre. How can these companies be _so_ bad at programming their devices?
[15:37] <haasn> I mean I get that in the case of our servers it's Sun/Oracle writing/maintaining it, and therefore it probably also runs on Java which explains 90% of that crap, but still
[15:37] <roaksoax> haasn: i guess the lack of rigorous testing against all the interfaces out there ?
[15:38] <haasn> roaksoax: But even their built-in web interface can lock itself up. You'd think they'd test at least that?
[15:39] <haasn> It seems like a case of “well, if the user power cycles the machine it fixes itself so let's just ship it with a line of documentation alluding to that”
[15:39] <roaksoax> haasn: i'm sure they do! You'd imagine that these things, being so important, take more attention, but I guess that shipping so many different firwmare version with so many different systems, takes a toll
[15:40] <haasn> (They would probably be more stable if they figured out some way of getting BSD-like microkernel + a small existing httpd to run on them instead of writing their own NIH web server :p)
[15:41] <haasn> Maybe even faster
[15:47] <roaksoax> hehe
[15:53] <imranh> https://www.youtube.com/watch?v=GZeUntdObCA a great talk on BMCs
[16:02] <nagyz> roaksoax, is there a way to deploy currently a node with a bond0 interface without any network associated to it, but have VLAN interfaces on different networks?
[16:02] <nagyz> I don't seem to be able to click through this via the UI.
[16:22] <imranh> hmmm the openstack installer is currently telling me i have no machines enlisted with power control
[16:37] <imranh> Nevermind, me being silly

[21:30] <bbaqar1> Hey guys .. Any
[21:30] <bbaqar1> Anyone got this bug recently?
[21:31] <bbaqar1> https://bugs.launchpad.net/maas/+bug/1520645
[21:32] <bbaqar1> @roaksoak
[21:41] <roaksoax> bbaqar1: not really
[21:42] <roaksoax> bbaqar1: what do you see exactly? VM's failing to enlist ?
[21:42] <bbaqar> Yes.
[21:42] <roaksoax> bbaqar1: do you have console logs to look ato? maas logs (regiond.log, clusterd.log)
[21:42] <bbaqar> Which exact logs would you like to see. I can get them once I get access to the setup again.
[21:43] <roaksoax> bbaqar: 1. console log of the machine trying to enlist 2. regiond.log 3. clusterd.log (the latter 2 around the time you were trying to enlist)
[21:44] <bbaqar> Okay got it. Will check them out.
[21:44] <roaksoax> bbaqar: thanks!
[21:44] <roaksoax> bbaqar: do share1, that will allow to see what may be wrong
[21:46] <bbaqar> Where to get the console.log of the enlisting node?
[21:46] <roaksoax> bbaqar: from the console of your enlisting node :
[21:46] <roaksoax> )
[21:46] <roaksoax> bbaqar: we don't record that info
[21:47] <bbaqar> aah i get it. thats what I was confused about. Will get back to you soon.
[21:47] <bbaqar> thanks.
[21:53] <bbaqar> roaksoax: Connecting a node to two subnets with both managing DHCP and DNS should not be a problem right?
=== lutostag_ is now known as lutostag
[22:07] <roaksoax> bbaqar: that may indeed be the problem dependending on how dhcp is configuring them
[22:10] <bbaqar> roaksoax: I did disconnect all cables from the node apart from just one but still got the error. Where can I remove all node specific information from in maas? dhcp.leases?
[22:11] <roaksoax> bbaqar: has the node been added to MAAS ?
[22:11] <roaksoax> bbaqar: if the node is not added to MAAS then you don't need to worry about dhcpd.leases
[22:11] <bbaqar> Basically it fails with the following error: "failed to enlist system maas server 'compute.maas'" where compute.maas is the fqdn of a already added node
[22:11] <bbaqar> no it hasnt. the enlistment was never succesful.
[22:12] <roaksoax> bbaqar: interesting! so what's happening is that the enlistment is doing a dig to try to find out the hostname
[22:12] <roaksoax> if theres any
[22:12] <roaksoax> bbaqar: and tries to enlist it
[22:13] <roaksoax> bbaqar: do you have an external dhcp server ?
[22:13] <roaksoax> err
[22:13] <roaksoax> DNS server ?
[22:13] <bbaqar> not a dhcp serve.
[22:13] <bbaqar> i can check if there is dns server running or not.
[22:14] <bbaqar> but why does it get the wrong hostname
[22:14] <bbaqar> i mean right at that time its a baremetal node so doesnt really have a hostname
[22:15] <roaksoax> bbaqar: try this: http://paste.ubuntu.com/15183875/ on /etc/maas/preseeds/enlist_userdata
[22:15] <roaksoax> bbaqar: and try to re-enslit. That should fix your issue
[22:18] <bbaqar> Okay cool. so i have to remove those three lines.
[22:18] <bbaqar> Great I ll try it out soon. Thanks a bunch.
