thorst_efried: That one above, you've been interlocked on?16:46
tblakesthorst: Just saw your comment on https://review.openstack.org/#/c/354179/ about using self.instance.name16:46
tblakesinstance.name is used to revert the name back to the original, is that an issue?16:47
tblakeshttps://github.com/openstack/nova-powervm/blob/e90cc307ddd015d915fda7b555cc66d06274a416/nova_powervm/virt/powervm/driver.py#L136416:47
thorst_yeah, because at that point in the code, you don't actually know that that was the original name16:47
thorst_it fixes your bug...but what if you were renaming from a different original name16:47
*** tblakes_ has joined #openstack-powervm16:47
efriedthorst_, yes, mdrabe and I have been working through that bug.  Last we spoke (less than an hour ago) he was going to verify that there were no other gotchas related to initializing the rebuild map before the LPAR was created.  Assume the above review has that taken into account.16:48
thorst_sweet...just know you're smarter about that crap than I am16:49
efriedMeanwhile, I will pay anyone a million dollars to get my freaking victim to stack AIO.16:49
thorst_lol16:49
thorst_talk to esberglu and adreznec16:49

efriedthorst_, where can I find your devstack hacks?16:56
thorst_what error are you hitting.  If AIO, I don't think you'd hit the same16:57
thorst_just pastebin it?16:57
*** tblakes has quit IRC17:00
efriedI don't know what a pastebin is.17:01
efriedthorst_ http://pastebin.com/6izgjtw717:02
thorst_efried: yeah, that's a different problem than what any of us are hitting.17:02
efriedWell, I hacked the keystone version thinking that could help, but it didn't.17:03
efriedlemme revert and do it again17:03
thorst_ahh17:03
efriedBut the previous error was very similar.17:03

*** thorst_ has quit IRC17:14
adreznecFYI efried I'm stacking a brand new AIO17:16
adreznecWith the latest from upstream17:16
adreznecI'll let you know if I hit the same issue as you17:16

adreznecI feel like I should just suggest that as the first fix for any problem at this point18:03

efriedthorst_, still looking for you to address replies to PS12 comments on https://review.openstack.org/#/c/343423/18:17

esbergluefried: Did you see that you now have to disable q-l3 and neutron-l3?18:21
efriedExplicitly put 'em in the disable list?18:22
efriedno, will try.  Thanks.18:22
adreznecYeah... maybe that will work18:22
adreznecI'm restacking again now18:22

efriedthis is happening on both VIOSes.19:20
efriedlots of messages to the console.19:20
efriedCan't log in.19:20
seroyerOn log in to the VIOS?  That’s a pretty good indicator that writes aren’t working.  Don’t prove that the disk was yanked (could be full).  But yanked is the most likely cause.19:21
seroyerDoesn’t *19:21
*** tblakes has joined #openstack-powervm19:25

svenkatefried: are you asking the physical ports of sriov on this host? i just did a pvmctl sriov list19:29
efriedsvenkat, no, the boot disks backing the VIOSes.  I have reason to believe they've been yanked out from the SAN.19:29
svenkatoh19:29
svenkati can ping vios but not able to ssh into it19:31
adreznecHmm19:31
adreznecnot a good sign19:31

thorst_(I/O backing system is going offline)19:45
