u1helppleaseU1 has been acting up for the past week or so. It gives this error repeatedly http://paste.ubuntu.com/443740/  . I noticed the bulletin from May 24th, but I had to seek help. The sync daemon is using 400-500 MB of ram.02:09
duanedesignhello u1helpplease02:22
u1helppleaseyes hello02:22
duanedesignu1helpplease: they will be testing the new fixes tommorrow, so hopefully we will be seing improvements in performance before the end of the week02:23
u1helppleasethanks for your time. Can the sync daemon be run with ulimit -m?02:24
duanedesignu1helpplease: hmm, i am not sure02:27
u1helppleaseit doesn't i tried "ulimit -m 64000 -v 128000 /usr/lib/ubuntuone-client/ubuntuone-syncdaemon" no luck still 500mb thanks though. Best of luck tomorrow. I will have another 25 gig coming your way.02:45
duanedesignu1helpplease: if you come by tommorrow between 12:00-20:00 GMT roughly, a lot of the devs are on02:47
dobeyyou would need to put the ulimit on python probably03:56

koshariwhats the 10.04 procedure to sync the files in 2 dirs on 2 diff machines, it seems the folders are not syncing to the server?09:28
beunokoshari, our servers are thrashing like crazy09:30
beunowe're working on scaling them09:30
beunobut we're still having our ups and downs09:30
kosharii see09:30
kosharibeuno because a new kernel has just hit the repos?09:33
beunokoshari, no, because we grew 200k users in 2 months  :)09:34
kosharibeuno: ah one of the pitfalls of success i guess :-)09:36
diverse_izzuehonk. i'm about to lose patience with U1. how's this upgrade of the server infrastructure coming along?10:21
beunodiverse_izzue, we're working non-stop10:22
beunoit gets increasingly harder, because people's syncs are backed up10:22
beunoso we add more capacity and tune performance, but load continues to increase10:22
beunowe have more work being rolled out that should help us get over the hump10:23
diverse_izzuebeuno, ok, sorry for bitching. i can stop running it for a while, and try again in a week or so10:23
beunoI've been trying to sync for a few days as well  :(10:23
beunodiverse_izzue, it's ok, we have almost 500k users, so a few won't make a difference10:23
beunoleave it on, we hope it will be back to normal-ish in a few days10:24
diverse_izzuebut, beuno, a general question. i enabled u1 sync on the directory where my phd thesis lives that i'm working on, because i want that backed up. of course those files are very regularly changed and saved. is that a problem for u1 (in a scenario where the servers are running fine)?10:24
beunodiverse_izzue, it's not a problem, no10:25
beunoat the moment, we don't upload deltas, so you will upload the full file each time you save10:25
beunoit's not optimal, but it won't create problems10:25
diverse_izzuebeuno, i am actually running into problems because it often creates .u1conflict files and then my latex compilation fails10:26
beunodiverse_izzue, are you working on different machines?10:26
beunoif its on the same machine, then it's absolultely a bug10:27
diverse_izzuebeuno, it is only one machine10:27
beunodiverse_izzue, it should not happen10:27
diverse_izzuei have u1 enabled on 2 machines, but the other machine is not online now10:27
beunodiverse_izzue, edit .config/ubuntuone/syncdaemon.conf10:28
beunoand add:10:28
beuno[logging]10:28
beunolevel = DEBUG10:28
beunorestart syncdaemon10:28
beunothe next time you get a u1conflict10:28
diverse_izzuewait i don't understand10:29
diverse_izzueshould i change the file now?10:29
beunofile a bug report and include the .cache/ubuntuone/log/syncdaemon.log10:29
beunoyes10:29
beunoso you can log more stuff10:29
diverse_izzueand then when it happens restart the daemon?10:29
beunoit will start logging in more detail10:29
beunoso when you hit this problem again10:30
beunoif you hand us the ~/.cache/ubuntuone/log/syncdaemon.log file10:30
beunowe can find the problem10:30
diverse_izzueok, i changed logging level now, will let you know if it happens. thanks for the help. i'll let you work now and do sth. myself. bb.10:30
beunodiverse_izzue, np, thanks10:31

duanedesignrye: I was talking to bodhizazen and I mentioned your latest blog post. He wanted me to pass along this link. He thought you might find it helpful. http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6-Beta/html/Resource_Management_Guide/pr02.html13:23
ryeduanedesign, cgroups... nomnomnom - i thought it was lxc-specific...13:25
duanedesignHe said "Those pages are fast reading and review cgroups, best linky I know of for cgroups, which of course is how one manages LXC containers /  processes ...."13:25

ryesylarpowa, currently the file sync is in process of being updated to become a lot faster16:33
ryesylarpowa, you might have noticed that during last 4 weeks performance was gradually decreased and today first 2 servers were switched to new system16:34
sylarpowarye: actually I think no file has been updated, is there any way to check the status of the update on my system?16:35
ryesylarpowa, you can run u1sdtool --waiting-meta in the terminal to see the items that are queued in meta queue - https://wiki.ubuntu.com/RomanYepishev/UbuntuOne/ClientControl16:36
sylarpowarye: thanks16:40
ryesylarpowa, there will be an announcement on identi.ca/mailing-list once we find out that file sync performance is restored16:42
sylarpowarye: actually I'm trying to update some files from many days, maybe 2 weeks16:43
sylarpowabut nothing happens16:43
ryesylarpowa, that's exactly the symptoms i am describing. It should be possible to perform full sync later today16:50

PaulGitEvening all.  I purchased some music this morning on via the U1 Music Store and it is still marked as queued and has yet to be moved to my U1 storage....is there a known issue?18:41
PaulGithonk18:42
mkarnickiPaulGit: you can wait for a better reassuring answer, but I can tell you there is *much* maintanance done today over the server side18:49
mkarnickiPaulGit: so I think it's much related.18:49
PaulGitmkarnicki: Thanks for that.  I have just looked via the webui and the files are there so the Rhythmbox UI is telling lies....need to look into why they are not being downloaded to my desktop....18:50

giohi fecundo and rye and others19:20
giotwo days ago I wrote about 2.6.34-5 kernel and ubuntuone19:20
giobecause 2.6.34-5 kernel seems break U119:21
gio(desktopcouch really)19:21
gioAre there news about this issue?19:22
ryegio, there is a bug report for that, let me find it for you...19:24
giothank you19:24
ryegio, bug #58847819:26
ubot4Launchpad bug 588478 in desktopcouch (Ubuntu) (and 1 other project) "RuntimeError: Can not find port of couchdb. (affects: 8) (dups: 3) (heat: 54)" [High,Confirmed] https://launchpad.net/bugs/58847819:26
giothank you. In your opinion, is this a kernel related bug or a desktopcouch bug?19:28
gioI do this question because I'm using 2.6.34-4 and U1 works fine19:31
ryegio, i feel that's dc bug, since parsing of /proc/$pid/net/tcp does not produce any results. Either it should search better or do something better to determine listening port19:34
giobut, strangely, with 2.6.34-4 dc works, so the question is: why? :)19:36
ryegio, hmmm, in 2.6.32 /proc/$pid/net/tcp contains more entries than in .34 in maverick19:39
gioWell, I try a comparison later19:40
giothanks19:40
