00:01	<@mikegrb>	they had a message during the bumpers this evening
00:01	<Battousai>	i find it hard to believe that a) of all the cities that was done in, paranoid boston was the only one uninformed, and b) nobody in boston knew about it for two weeks
00:01	<Battousai>	haha, the turner apology
00:01	<@mikegrb>	"we are sorry for any blah blah we have provided a list of all locations to federal blah blah"
00:02	<guinea-pig>	nothing ever HAPPENS in boston, but they ALWAYS freak out over the littlest things.
00:03	<Battousai>	well in their defense, one thing did start in boston
00:05	<guinea-pig>	the tea party?
00:05	<guinea-pig>	the great moleasses flood?
00:05	<@mikegrb>	no, the boston marathon
00:05	<guinea-pig>	that doesn't start in boston. it ends in boston.
00:05	<Battousai>	9/11
00:05	<@mikegrb>	hush
00:05	<guinea-pig>	it starts in ....umm... hopkinton
00:06	<guinea-pig>	Battousai: but boston is never a target. that's what makes it such a great city :D
00:07	<Battousai>	boston is its own target, heh

02:22	<marc_in_lux>	good morning
02:22	<ajmitch>	hello
02:22	<marc_in_lux>	my migration's been running for an hour and a half now...
02:23	<ajmitch>	from TP to HE?
02:24	<marc_in_lux>	both hosts say fremont
02:25	<ajmitch>	then that's a rather slow migration :)
02:25	<ajmitch>	unless the box you're migrating off has had disk issues?
02:25	<marc_in_lux>	it would seem so... it was described as 2-3 minutes a gig. Wish I had those gigs
02:25	<marc_in_lux>	shouldn...

08:11	<heidi>	i get the error too
08:11	<heidi>	mikegrb knows about
08:11	<heidi>	it
08:11	<heidi>	it will probably be fixed when someone gets up
08:11	<heidi>	it is just now 8
08:12	<iggy>	you're up
08:12	<heidi>	heh
08:12	<heidi>	yeah, but I get up when the 2 year old gets up
08:12	<heidi>	and I don't fix linode things
08:13	<heidi>	since mikegrb was up until 2 am, he gets to sleep in a little since the forums aren't an emergency situation
08:13	<marc_in_lux>	what time zone is that... central?
08:13	<heidi>	yep
08:14	<marc_in_lux>	I am considering to end my work day in about an hour or so ;-)
08:14	<heidi>	nice
08:19	<guinea-pig>	i hate waking up at 9am when i'm on third shift :/

08:33	<Deckert>	ummm ....
08:33	<Deckert>	so this question may have com eup ... but does anybody know what happ'd to the forums?
08:35	\|-\|	fh [~be362403@webuser.linode.com] has joined #linode
08:43	<iggy>	Deckert: they are aware and it'll be fixed posthaste(sp?)
08:45	<Deckert>	iggy: thanks... anybody know what happened? (i.e. did it also affect the registration system?)
08:47	<npmr>	borked for me too
08:48	<heidi>	Deckert: it doesn't seem to have affected anything else
08:48	<heidi>	I don't know for sure though
08:48	<heidi>	but the website itself seems fine
08:49	<iggy>	I think the forums are on a seperate system
08:51	<Deckert>	the website was down as well earlier ...
08:51	<Deckert>	it recently came up ... so I wondered to the forums to go see what happened ...
08:51	<Deckert>	:-)
08:53	\|-\|	fh [~be362403@webuser.linode.com] has quit [Quit: CGI:IRC (Ping timeout)]
08:56	<heidi>	there was probably a problem with the forum not coming back up properly
09:01	<Deckert>	agreed ... the linodes themselves are fine ... (mine is running fine, at least)
09:01	<npmr>	i wouldn't be here if mine weren't
09:01	<guinea-pig>	i wouldn't be here, guinea-home would be
09:01	<npmr>	nova's had problems lately
09:01	<guinea-pig>	nova done sploded
09:02	<npmr>	maybe this is just more of that
09:02	<guinea-pig>	yay more splodey
09:02	<npmr>	just what boston needs
09:03	<guinea-pig>	yay no more boston

12:17	<tjfontaine>	yes
12:18	<tjfontaine>	well, generally speaking in VMs
12:18	<tjfontaine>	it is possible in vmware, and I'm fairly certain in Xen as well
12:18	<iggy>	I know xen can, I just can't find anything definitive for uml
12:19	<iggy>	I'm gearing up to do a bunch of benchmarks on uml, xen-3.0, xen-3.1, and kvm

13:33	\|-\|	adamg [~misthos@zeus.misthos.com] has joined #linode
13:49	<iggy>	that's cool, I didn't know caker released the token-limiter patches
13:51	<Darxus>	I didn't realize he patched it
13:51	<Darxus>	what did he change?
13:52	<@mikegrb>	he wrote it
13:55	<Darxus>	oh, damn, nice :)
13:55	<npmr>	http://www.theshore.net/~caker/uml/patches/ <-- yoink
13:55	<Darxus>	ahh... the token limiter was a patch to uml?
13:55	<npmr>	yes
13:55	<Darxus>	got it
13:55	<Darxus>	still cool
13:56	<iggy>	it seems effective
13:57	<npmr>	i don't like the failure mode
13:58	<npmr>	i think the timeout should phase in
13:59	<Darxus>	phase in?
13:59	<npmr>	yes
14:00	<Darxus>	and things don't just block until you get more tokens?
14:00	<npmr>	as token_count approaches 0, the i/o timeout should increase as a function of it
14:00	<npmr>	until token_count is 0 and the timeout is 1000 ms
14:00	<Darxus>	what happens when you run out of tokens?
14:00	<npmr>	<npmr> until token_count is 0 and the timeout is 1000 ms
14:01	<iggy>	effectively your box locks
14:01	<npmr>	well, that's what happens now
14:01	<npmr>	the i/o delay 0, 0, 0, 0, 0..... until you're out of tokens and then it's suddenly 1000 ms
14:02	<npmr>	i think the delay should be an inverse function of token_count
14:02	<Darxus>	iggy: temporarily until you get more tokens?
14:02	\|-\|	adamg [~misthos@zeus.misthos.com] has quit [Ping timeout: 480 seconds]
14:02	<npmr>	tweaked so that token_count <= 0 translates to a 1000 ms delay
14:02	<Darxus>	npmr: how would that help?
14:02	\|-\|	SpaceHobo [~spacehobo@host-84-9-50-117.bulldogdsl.com] has joined #linode
14:02	<npmr>	and token_count > 100000 is somewhere around 5 or less
14:03	<iggy>	Darxus: yeah, things get better as you get tokens
14:03	<npmr>	Darxus, it would allow a thrashing linode to reach equilibrium rather than hit a brick wall at which point nothing is possible
14:05	<npmr>	i guess it's actually io_tokens, not token_count
14:10	<Darxus>	npmr: what makes you think slowing down the i/o would cause it to reach equilibrium instead of just more slowly grinding to a hault?
14:12	<npmr>	slowing down the i/o is what currently takes place
14:12	<npmr>	that is what the i/o limiter does when you run out of tokens
14:12	<iggy>	because things would start slowing down and whatever service is getting hammered would slow down (instead of halt) and people would try back later instead of hitting it more thinking it would start responding
14:12	<npmr>	but it happens all at once, the moment io_tokens hits 0
14:13	<Darxus>	npmr: sounds to me like that 1000ms delay is just blocking (hanging) until the next refil, which makes sense to me... no slowing, just hanging until refil
14:13	<npmr>	try running out of tokens
14:13	<Darxus>	and I would expect causing it to gradually slow down would cause lots of overhead in a bad place
14:13	<iggy>	yeah, try it
14:14	<npmr>	as someone who has experienced many token exhaustions, i would prefer a gradual increase of token_delay
14:14	<iggy>	I think I would too
14:15	<npmr>	the sudden slowdown causes lots of overhead in bad places, too
14:15	<Darxus>	haha woa...
14:15	<npmr>	i'm not saying that a gradual slowdown doesn't
14:15	<Darxus>	while : ; do find / > /dev/null 2&1 ; done
14:15	<npmr>	what i am saying is that it's gradual, and not sudden
14:15	<Darxus>	^ caused it to repeatedly run a backgrounded find instead of redirecting stderr :P
14:16	<npmr>	Darxus, "find / -type f \| print0 \| xargs -0 md5sum \| sort -u"
14:16	<Darxus>	npmr: I can't imagine that would help any more than "while : ; do find / > /dev/null 2>&1 ; done"
14:17	<npmr>	it would cause all of the blocks of all of your files to be traversed
14:17	<Darxus>	holy shit that isn't droping my tokens
14:17	<npmr>	your find invocation will only traverse the directory inodes
14:17	<npmr>	and there's probably enough memory to cache those
14:18	<Darxus>	while : ; do find / -type f \| xargs cat > /dev/null 2>&1 ; done
14:18	<Darxus>	^ same effect without hitting cpu with md5sum
14:18	<npmr>	sure
14:19	<npmr>	wc -b, for that matter
14:19	<npmr>	how's your io_status?
14:20	<Darxus>	io_count=13126053 io_rate=513 io_tokens=-90 token_refill=512 token_max=400000
14:20	<Darxus>	still feeling good
14:20	<npmr>	try reading your mail with no tokens
14:20	<Darxus>	okay ctrl-a,c is not very responsive :)
14:21	<Darxus>	heh reading my email with mutt is going just fine
14:21	<npmr>	was mutt already open?
14:21	<Darxus>	yes
14:21	<Darxus>	quitting and restarting is slow
14:21	<npmr>	well then it was already in memory
14:21	<Darxus>	ctrl-a,c is taking about 2 seconds
14:21	<npmr>	and probably a lot of your mbox, too
14:22	<npmr>	Darxus, yes, and that's on a system under artificial load
14:22	<npmr>	generally, people run out of tokens under real load
14:22	<Darxus>	okay that was fun
14:22	<Darxus>	but I still don't see why you think a gradual slowdown would be helpful
14:23	<npmr>	equilibrium
14:23	<Darxus>	maybe if there was a way to give root first access to tokens...
14:24	<npmr>	yeah, no
14:24	<npmr>	that wouldn't work for the modern sysadmin
14:28	<Darxus>	hmm
14:28	<Darxus>	doesn't linux have builtin stuff to kill off processes that are hosing the system?
14:29	<SpaceHobo>	OOMKILLER
14:29	<SpaceHobo>	all it ever needed was a D
14:29	<iggy>	running out of tokens isn't the same thing as running out of mem... nor would I want it to be
14:29	<SpaceHobo>	trust me, the oomkiller is a pretty drastic situation
14:29	<SpaceHobo>	you are rarely sure enough of what died and what still lives to patch things up
14:29	<SpaceHobo>	and usually end up rebooting just for completeness's sake
14:30	<iggy>	processes freezing for a while is better than them being killed and not noticing till one of your clients calls and says their site is down or they aren't getting mail
