<rickogden>
morning
09:22
<alkisg>
Good morning
09:22
<rickogden>
I'm aware that if I do a poweroff -fp it doesn't cleanly close the NBD connection, but poweroff does
09:22
can I run a command to manually close the NBD connection before poweroff -fp?
09:23
<alkisg>
Supposedly the /usr/share/ltsp/nbd-disconnect code does just that
09:23
But maybe the ubuntu hooks are wrong for that file...
09:24
<rickogden>
thanks, I'll give it ago
09:24
<alkisg>
I.e. it should work automatically
09:24
Without you doing anything
09:24
<rickogden>
ah ok
09:24
even if you do a force poweroff?
09:24
<alkisg>
No
09:25
<rickogden>
as I need to do poweroff -fp otherwise the client shuts down and but doesn't actually power off the machine
09:25
so I've replaced /sbin/poweroff with my own script on the client
09:26
(which simply calls poweroff with the -fp switch)
09:26
<alkisg>
Then the ubuntu hooks are wrong, nbd-disconnect isn't called and need to be fixed
09:26freedomrun has joined IRC (freedomrun!~freedomru@unaffiliated/freedomrun)
09:26
<ogra_>
alkisg, poweroff -fp wont call anything
09:27
it will force the kernel to power down immediately
09:27
<alkisg>
ogra_: yup
09:27
(11:24:42 πμ) rickogden: even if you do a force poweroff?
09:27
(11:24:45 πμ) alkisg: No
09:27
That's why I said "no" there
09:27
<ogra_>
so there is nothing to fix :)
09:27
<alkisg>
nbd-disconnect is called on normal shutdown
09:27
We no longer do poweroff -fp
09:27
That's rickogden's customization
09:27
<ogra_>
rickogden does in his script
09:27
<alkisg>
Yup
09:28
<ogra_>
and it works if he uses normal poweroff
09:28
<alkisg>
Yup
09:28
<ogra_>
so nothing is broken :)
09:28
<alkisg>
Nope
09:28
There are 2 issues
09:28
1) poweroff should work
09:28
2) the nbd connection should be closed
09:28
nbd-disconnect should handle both of them
09:28
<rickogden>
sorry, I'm horribly confused now
09:28
<alkisg>
The ubuntu hooks are wrong so nbd-disconnect isn't called so (1) doesn't work
09:29
And with his solution, (2) doesn't work
09:29
So Ubuntu needs fixing
09:29* ogra_ doesnt see where nbd-disconnect doesnt work above
09:29
<alkisg>
ogra_: it doesn't get called on the poweroff upstart event
09:29
While it should
09:30
Or, on the nbd-client service being stopped
09:30
<rickogden>
since the shutdown doesn't work for me, and Ubuntu is broken, shouldn't I manually call nbd-disconnect?
09:31
<alkisg>
rickogden: a patch for ubuntu needs to be found, and then you'd just need to use that in your installation...
09:31
<ogra_>
if the machine doesnt power down, it means that an upstart job didnt return so all other following jobs stay in wait
09:31
find the offending job ...
09:31
<alkisg>
ogra_: it's not just that
09:32
Some NICs prohibit poweroff if they're in up state (!)
09:32
Anyway, /me needs to do some remote support for some teachers here, later... :)
09:32* ogra_ waves
09:32
<ogra_>
... and goes to a meeting himself
09:33
<rickogden>
thanks for your help guys

<bennabiy>
vagrantc: what packaging replaced your old one?
21:35
<vagrantc>
bennabiy: i don't use launchpad
21:35
bennabiy: i think alkisg tried to set up another mirror
21:36
but probably failed with the wrong url or something
21:36
<alkisg>
Yeah, I think I had to upload the whole packaging branch manually the last time
21:37* alkisg would prefer it if the debian/ folder was upstream in ltsp-trunk... but that's a long story :D
21:38
<vagrantc>
alkisg: it was originally, but then wtogami got grumpy about it, and at the time it was actually technically difficult to do in debia anyways.
21:38
<alkisg>
wtogami has fedora packaging files upstream though :)
21:39
<vagrantc>
although i find some annoying issues with packaging in upstream... it's kind of hard to work with which branching a version from upstream.
21:39
the sad news is i don't have the skill with bzr to re-merge the debian dir again.
21:40
without loosing history
21:40
since the current packaging is a fork which removed and renamed a messload of files.
21:41
TONs of merge conflicts.
21:41
<alkisg>
vagrantc: btw since you're using launchpad for the code, why not do the same for the packaging too? Are there any advantages to using debian.org there?
21:41
<vagrantc>
alkisg: i prefer to use debian infrastructure for debian work
21:42
also, historically, launchpad wasn't even open source, although that changed a few years ago finally :)
21:42* alkisg would really like to be able to use launchpad recipes to build the latest ltsp/ldm etc, but unfortunately that's not easily possible now...
21:43
<vagrantc>
i can't find the mirroring options anymore
21:43
alkisg: i also liked having redundancy with having it both on launchpad and on debian infrastructure
21:43
the mirroring was (nearly) perfect for that...
21:44
although the delay in mirroring was somethings annoying
21:44
launchpad has some wack git importing features... hmmm.
21:48
<bennabiy>
thank you
21:49
vagrantc: which virt tech do you see as better, xen, kvm or other?
21:49
using debian as the base
21:49
I am in the process of migrating a few of our physical servers to virt, and have experimented with both xen and kvm.

21:52
alkisg: how'd you find it?
21:52
<alkisg>
vagrantc: from my #launchpad logs :D
21:52
Google failed me...
21:52
<vagrantc>
launchpad itself failed me...
21:53
<alkisg>
OK there's a link there: https://help.launchpad.net/VcsImports
21:56* alkisg created https://code.launchpad.net/~alkisg/ltsp/ltsp-debian-packaging ...
21:56* vagrantc wouldn't be surprised if alioth.debian.org URLs change again soonish
21:57
<vagrantc>
looks like i just re-added mine
21:59
<alkisg>
vagrantc: if you plan to add ldm/ltspfs too, I'll remove my imported branches...
21:59

alkisg: yeah, can.
