11:08 sc-rm_ When removing a compute node, openstack does not get notified and so in turn removes that node from it’s list of compute-nodes
11:16 evg sc-rm_: hi, I've may be got you wrong but what did you expect?
11:18 emagana joined #fuel
11:19 eshumkher joined #fuel
11:28 eshumkher_ joined #fuel
11:29 sc-rm_ evg: I expected Fuel to remove the node from openstack, so nova-manage does not have XXX for that node, becuase it should no longer be in the list
11:30 sc-rm_ evg: but it’s okay for now, just seen it because the healt check does complain about “Some nova services have not been started.. Please refer to OpenStack logs for more details.” hence the removed node

11:40 evg sc-rm_: I've got you. There is a bug related to this, i'm trying to find...
11:42 sc-rm_ evg: maybe this one https://review.openstack.org/#/c/39998/
11:42 sc-rm_ evg: removed it with sql altering in the control node
11:58 pasquier-s joined #fuel
12:11 sc-rm_ evg: why have fuel deployed the compute nodes and gives this error in health check “Instance is not reachable by IP. Please refer to OpenStack logs for more details.”
12:16 evg sc-rm_: is it HA deployment?
12:17 sc-rm_ evg: yep it is
12:18 evg sc-rm_: not this case https://bugs.launchpad.net/fuel/+bug/1318642 ?

13:51 sc-rm_ evg: I have played around and I can start instances, assing floating IP’s and asses the instances through those floating IP’s so don’t know if my test issue is related to it. Is there some log I could look into?

14:18 evg sc-rm_: you can see test's logs in fuel panel in Logs tab. Set source menu to "healthcheck"
14:20 evg sc-rm_: do you mean you've got no problem with assing ip? and the issue is only in tests?

14:59 ianunruh If I wanted to install some additional services on my OpenStack nodes using Puppet included with Fuel, is there any recommended way of doing that?
14:59 ianunruh such as monitoring software

15:33 kaliya ianunruh, you should customize the /etc/puppet on the master, starting from the site.pp
15:35 MiroslavAnashkin Or create new puppet manifest and locally run `puppet apply -e <your_manifest>`
15:41 ianunruh thank you both

18:57 kupo24z xarses: have you experimented with the different libvirt cache modes eg disk_cachemodes? Wondering what kind of problems unsafe causes
19:00 xarses not really, I do understand that unsafe can lead to data loss on power failure
19:01 kupo24z Is that just for data that is mid-transfer or does it have potental for losing saved data?
19:01 kupo24z I imagine journaling would help that issue as well
19:03 xarses anything that libvirt handles for the guest where the guest would think it was talking to a real device
19:03 xarses qemu even
19:05 xarses we will likely change rbd to disk_cachemodes="network=writeback"
19:05 kupo24z I'm getting very odd preformance with that with ceph firefly
19:06 kupo24z its decent 4k speeds, at around 128k it starts to go downward in test results
19:06 kupo24z where with 5.0 it was a steady climb
19:12 kupo24z I pasted my test results regarding that + the additional ceph changes here https://bugs.launchpad.net/fuel/+bug/1361391
19:12 kupo24z probably needs a newer libvirt which will come with 6.0 ubuntu 14 i would imagine
