Description Kartik Mistry 2014-03-18 13:05:28 UTC
We at Language Engineering team are using almost all instances at pmtpa Labs. Please assist us in migration from pmtpa to eqiad.

I can be available in process for migration.

The following instances need to migrate:

language-testlink
cxserver
language-browsertests
language-stage1
language-mleb
language-replag-wiki
language-replag-slave
language-replag-master

In short, all instances are in use and required. Let me know what other information is needed.
Comment 1 Andrew Bogott 2014-03-18 23:00:01 UTC
Puppet is disabled on the language-browsertests instance, which means I can not migrate it.  Re-enabling may cause unwanted side-effects -- do you know why it's disabled?
Comment 2 Kartik Mistry 2014-03-19 03:52:18 UTC
No idea :( We created instance as other instances were created. What can be possible downtime or side effects?
Comment 3 Andrew Bogott 2014-03-20 14:43:13 UTC
Well... someone on your team had to have explicitly disabled puppet on that box.  They probably did it for a reason -- to alter system files that are generally maintained by puppet.  When we turn puppet back on, these files may be overwritten.

I can re-enable and let the chips fall... the instance cannot be migrated without puppet.  Please let me know how you'd like to proceed.
Comment 4 Kartik Mistry 2014-03-21 03:31:54 UTC
Please go ahead!
Comment 5 Andrew Bogott 2014-03-21 03:47:03 UTC
OK, I'm starting this migration now... will update when complete.
Comment 6 Andrew Bogott 2014-03-21 05:03:46 UTC
I've migrated all of these instances now.  Please verify that things are working -- if it all looks good then close this bug and update the progress page accordingly.

Thanks!

-Andrew
Comment 7 Kartik Mistry 2014-03-21 10:42:34 UTC
Andrew, I'm getting '502 Bad Gateway' in all instances at moment. Do I need to change anything at Wikitech?

https://wikitech.wikimedia.org/wiki/Labs_Eqiad_Migration_Progress#Pending_Migration shows Pending for Language too.
Comment 8 Kartik Mistry 2014-03-21 11:52:39 UTC
Nevermind. After updating webproxies, things are into shape. Can you look at why, language-mleb (http://mlebtesting.wmflabs.org/) is still not working?
Comment 9 Andrew Bogott 2014-03-21 14:34:11 UTC
language-mleb is running something called 'aolserver' which is occupying port 80 and preventing apache from coming up.  I don't know if that's right or wrong, but in either case it's above my pay grade -- I've never heard of aolserver at all :(
Comment 10 Kartik Mistry 2014-03-24 06:53:01 UTC
I fixed 'aolserver' issue on language-mleb today.
Comment 11 Andrew Bogott 2014-03-24 14:42:10 UTC
OK, can this bug be closed, or do you still need assistance from me?
Comment 12 Kartik Mistry 2014-03-24 15:07:06 UTC
No. Thanks a lot, Andrew! Closing.
Comment 13 Andrew Bogott 2014-03-24 15:12:04 UTC
Can I move the language project into the 'fully migrated' column?
