| |
| 04:17 | <vagrantc> never saw em, though there's a post on the mailing list that sounds like the same issue

| |
| 04:24 | <ccat> vagrantc: no, don't really have any test pc set up

| |
| 04:26 | adrianorg has joined IRC (adrianorg!~adrianorg@179.179.75.61) | |
| 04:26 | <vagrantc> probably enough to test.

| 04:31 | <ccat> vagrantc: well for now all focus is on getting new powerful pc for cad -- and worrying about remote access after that --- as just trying to wade through (Dell's) options is maddening enough. For eg: Aaaaaaaggg!

| |
| 08:02 | grembler > i am facing these problem if u can help me so please ....
| |
| 08:03 | <Grembler> an arp timeout would indicate that networking is broken as a very low level
| |
| 08:04 | is your network problematic?
| |
| 08:04 | <sanjay> so what i have to do ....
| |
| 08:05 | i am new in ltsp..
| |
| 08:08 | <Grembler> I would write to the mailing list with which clients you are using, and a full output of the error produced
| |
| 08:08 | does the client get any kind of DHCP lease at all?

| |
| 08:16 | <Grembler> you need to give the full error output
| |
| 08:17 | <sanjay> PXE-E11 ARP timeout
| |
| 08:17 | TFTP CANNOT OPEN CONNECTION
| |
| 08:18 | Existing broadcom PXE ROM
| |
| 08:18 | Selected boot device not available
| |
| 08:18 | exactly there error giving...
| |
| 08:33 | grmbler>???
| |
| 08:52 | <Grembler> you need to test if TFTP is correctly installed and running
| |
| 08:52 | try a simple tftp get on the server first
| |
| 08:52 | if that works, try on another machine on the same network
| |
| 08:53 | if neither work, you'll have to figure out why

| 16:13 | * vagrantc thinks is morning in the americas | |
| 16:20 | <joe_sizlack> Chicago
| |
| 16:22 | anyone think it odd to have a 2gig bond be saturated but 50 or so NFS fat clients?
| |
| 16:22 | s/but/by
| |
| 16:24 | <alkisg> Libreoffice needs 120 mb to load, multiply that fifty times ...
| |
| 16:24 | NBD + squashfs will be 5 times faster
| |
| 16:25 | * vagrantc should continue to explore the NFS image option | |
| 16:25 | <alkisg> Yeah that'd be very fast too, e.g. 4+ times faster than plain nfs
| |
| 16:25 | <joe_sizlack> gotta stick with nfs for HA sake
| |
| 16:25 | <alkisg> Switch to NFS + squashfs then
| |
| 16:26 | I.e. a single i386.img served over NFS
| |
| 16:26 | <joe_sizlack> ah
| |
| 16:26 | <alkisg> That's only 10% slower than nbd+squashfs
| |
| 16:26 | <joe_sizlack> I'll look into that
| |
| 16:26 | <vagrantc> i *think* that made it into ltsp 5.5.0
| |
| 16:26 | but it was barely tested
| |
| 16:27 | * alkisg tested that but I don't know if all code was upstream... | |
| 16:27 | <alkisg> joe_sizlack: and of course you might also be able to use...
| |
| 16:27 | !local-boot
| |
| 16:27 | <ltsp`> local-boot: If you want LTSP fat clients on a low-speed network, you can put i386.img on e.g. C:\Boot\LTSP\i386.img and use this command line in pxelinux.cfg: APPEND ro initrd=ltsp/i386/initrd.img init=/sbin/init-ltsp root=/dev/sda1 rootflags=ro loop=/Boot/LTSP/i386.img; IPAPPEND 3
| |
| 16:27 | <joe_sizlack> haha, yea
| |
| 16:27 | I was looking into that as well
| |
| 16:27 | a while back
| |
| 16:28 | <alkisg> You can copy the image with 1 command if you're using epoptes
| |
| 16:28 | <joe_sizlack> it presents some troubles for me
| |
| 16:28 | <alkisg> ok
| |
| 16:28 | <joe_sizlack> i.e. people might steal the cards
| |
| 16:28 | <alkisg> No internal storage?
| |
| 16:28 | <joe_sizlack> nah
| |
| 16:28 | just sd's
| |
| 16:28 | sd slots that is
| |
| 16:29 | guess I could glue in the cards or something...
| |
| 16:29 | I'm also still running ltsp 5.4
| |
| 16:30 | nfs+squash didn't make it in until 5.5?
| |
| 16:30 | <alkisg> It shouldn't be hard to backport it
| |
| 16:30 | <||cw> joe_sizlack: what speed nics in the fat clients?
| |
| 16:30 | <alkisg> It just involves one or two scripts...
| |
| 16:30 | <vagrantc> i upstreamed something
| |
| 16:30 | it was surprisingly simple
| |
| 16:30 | <joe_sizlack> 10/100's
| |
| 16:31 | <vagrantc> mount internally?
| |
| 16:31 | <joe_sizlack> not sure I follow?
| |
| 16:31 | <vagrantc> it's just a single initramfs-tools hook, it hink
| |
| 16:31 | <joe_sizlack> oh
| |
| 16:31 | <vagrantc> probably can drop it in and should work on ltsp 5.4.x
| |
| 16:33 | <joe_sizlack> due you or have you guys had to tune your nfs mount options at all in the past?
| |
| 16:34 | or have you just run with things straight from the package?

| 16:35 | alkisg1 is now known as alkisg | |
| 16:35 | <alkisg> (06:31:34 μμ) alkisg: You could also use more network cards, or more nfs/nbd servers...
| |
| 16:35 | <joe_sizlack> yea, I've got a couple more NIC's on the way
| |
| 16:36 | <vagrantc> i've never done much tuning, but i haven't done any HA stuff
| |
| 16:36 | <joe_sizlack> just thought it might be odd
| |
| 16:36 | "vers=3,rsize=1048576,wsize=1048576,namlen=255" for instance
| |
| 16:36 | ltsp mounts root with these, standard
| |
| 16:37 | <alkisg> It's just the initramfs-tools/klibc defaults...
| |
| 16:37 | <vagrantc> that might matter even more for NFS image support
| |
| 16:37 | wsize is kind of silly for a read-only moun. heh.

| 16:37 | i haven't touched nfs options for probably 10 years
| |
| 16:37 | <alkisg> initramfs-tools also doesn't support nfs4, while dracut does, afaik...
| |
| 16:38 | <vagrantc> finally, something good about dracut
| |
| 16:38 | <joe_sizlack> haha
| |
| 16:38 | yea, I wish I had v4 for the root
| |
| 16:39 | i did find that writing my browser's cache to a tmpfs mount sped things up and dropped traffic considerably, btw
| |
| 16:40 | if you guys wanna role something like that into the lts.conf for fat clients, it'd be rad :)
| |
| 16:40 | <alkisg> File a bug report with the steps involved...
| |
| 16:40 | <joe_sizlack> k
| |
| 16:40 | <alkisg> !bug
| |
| 16:40 | <ltsp`> bug: To file a bug report for upstream LTSP, go to https://bugs.launchpad.net/ltsp
| |
| 16:41 | <alkisg> Where does the browser cache usually go?
| |
| 16:42 | <joe_sizlack> /home/$user/.cache
| |
| 16:48 | <vagrantc> you're using NFS homedirs?
| |
| 16:48 | or sshfs?
| |
| 16:48 | <alkisg> But not the whole .cache can be in a tmpfs, right? Because it'll slow down startup of some programs a lot...
| |
| 16:48 | * vagrantc thinks it makes a lot of sense | |
| 16:48 | <alkisg> ...because they'd recreate the .cache from scratch each time...
| |
| 16:49 | <vagrantc> depends on how much theey rely on .cache
| |
| 16:49 | <alkisg> I wouldn't want to have to check each program though
| |
| 16:49 | <vagrantc> if you were using the same homedir for thin clients and fat clients, you might get interesting results
| |
| 16:49 | <alkisg> To see which ones benefit from that and which ones don't
| |
| 16:49 | <vagrantc> it's an interesting idea, for sure
| |
| 16:50 | oh, there's a package that does this!
| |
| 16:50 | i may even use it on my netbook
| |
| 16:50 | <joe_sizlack> https://bugs.launchpad.net/ltsp/+bug/1284724
| |
| 16:50 | nfs, yea
| |
| 16:50 | <vagrantc> unburden-home-dir
| |
| 16:50 | does exactly that
| |
| 16:50 | not sure how it would integrate with LTSP...
| |
| 16:51 | <joe_sizlack> not the whole .cache, no
| |
| 16:51 | just for browsers
| |
| 16:51 | yea, profile-sync-daemon is a package that does it to cut down on read/writes
| |
| 16:51 | that's where I got the idea
| |
| 16:52 | <vagrantc> my guess is the performance gains would be well worth it
| |
| 16:52 | vlt has left IRC (vlt!~hrst@lvps178-77-99-218.dedicated.hosteurope.de, Ping timeout: 264 seconds) | |
| 16:52 | <joe_sizlack> they are
| |
| 16:52 | i saw a huge improvement
| |
| 16:53 | <alkisg> eatmydata?!
| |
| 16:54 | <joe_sizlack> haha
| |
| 16:54 | <alkisg> Assuming the ltsp server doesn't crash, and only thin/fat clients do crash, what would be the downside to using eatmydata, which disables fsyncs, on clients
| |
| 16:54 | ?
| |
| 16:56 | <joe_sizlack> interesting
| |
| 16:56 | * alkisg also wonders if sshfs, without -o sshfs_sync, performs any better than nfs... | |
| 16:57 | <vagrantc> using eatmydata on fatclients ...
| |
| 16:58 | <joe_sizlack> you think it would be dangerous?
| |
| 16:58 | <slackish> alkisg: might be interesting to try it.. especially with -o ssh_command="ssh -c arcfour"
| |
| 16:58 | <joe_sizlack> well, too dangerous
| |
| 16:58 | <alkisg> !arcfour | echo slackish:
| |
| 16:58 | <ltsp`> slackish: arcfour: http://en.wikipedia.org/wiki/RC4 is an SSH cipher which is more than 2 times faster than the default aes128-ctr. To enable it, set LDM_SSHOPTIONS="-o Ciphers=arcfour128".
| |
| 16:58 | * alkisg is currently using that in 500 schools... :) | |
| 16:58 | * vagrantc tries to think of a scenario where eatmydata would loose data that *might* otherwise get saved | |
| 16:59 | <slackish> :)
| |
| 16:59 | <vagrantc> didn't we discuss making arcfour the default at some point?
| |
| 16:59 | <alkisg> I don't remember the outcome there...
| |
| 16:59 | vagrantc: do we need eatmydata though, or do sshfs and nfs have mount options that ignore sync requests?
| |
| 17:01 | <joe_sizlack> nfs only has async afaik
| |
| 17:02 | that doesn't ignore sink but lets traffic continue to flow before it's certain it's been written
| |
| 17:02 | s/sink/sync :P
| |
| 17:03 | eatmydata or unburden-home-dir seem quite applicable
| |
| 17:03 | <vagrantc> alkisg: i think they both have options that are similar if not identical
| |
| 17:08 | <joe_sizlack> anyone think of anything catastrophic that might happen with eatmydata on a fat client crash?
| |
| 17:08 | I might try it...
| |
| 17:09 | <alkisg> Do you also have async for /home in /etc/exports?
| |
| 17:10 | <joe_sizlack> i do
| |
| 17:12 | JustSomeGuy has left IRC (JustSomeGuy!~JustSomeG@port-87-193-233-146.static.qsc.de, Quit: Verlassend) | |
| 17:13 | <vagrantc> for some dirs, unburden-home-dir copies a bunch of files, so it might be slow to startup
| |
| 17:13 | at login
| |
| 17:14 | oh, symlinks across filesystem boundaries with sshfs ... can cause interesting behavior
| |
| 17:15 | but maybe that will be fine
| |
| 17:15 | <joe_sizlack> unburden uses Xsession hooks at login
| |
| 17:15 | that'll work fine with LDM, yea?
| |
| 17:15 | <vagrantc> should
| |
| 17:16 | you'll need to enable on a per-user basis, or globally in /etc/default/unburden-home-dir
| |
| 17:16 | but it'd be easy to write an init-ltsp.d hook for that
| |
| 17:16 | globally, at least
| |
| 17:17 | <alkisg> sshfs symlinks under /home in ltsp are not followed on the server so they should be fine...

| 17:18 | <joe_sizlack> my guys have some pretty large homes in some cases
| |
| 17:19 | if it copies the entire /home/$user to RAM that would take quite a while indeed
| |
| 17:20 | <alkisg> joe_sizlack: have you verified that by putting the browser cache to ram, it indeed goes faster?
| |
| 17:20 | <vagrantc> undurden only copies specific cache files
| |
| 17:20 | although it's a long list
| |
| 17:20 | <alkisg> Or was that just because your network is saturated?
| |
| 17:22 | <joe_sizlack> nah, I did that weeks ago
| |
| 17:22 | Fenuks has joined IRC (Fenuks!~Fenuks@212.164.164.225) | |
| 17:22 | <joe_sizlack> it most certainly sped things up
| |
| 17:22 | <alkisg> And how much RAM on the clients, open tabs on the browser etc?
| |
| 17:23 | Does it only help when clients have little ram and users have a lot of tabs open?
| |
| 17:23 | <joe_sizlack> 4gigs on the clients that are happy
| |
| 17:23 | 2gigs on the clients that still complain a bit
| |
| 17:24 | they probably open a ton of tabs though
| |
| 17:24 | at least 10 or 15
| |
| 17:26 | I intend to have them all at 4gigs soon though
| |
| 17:27 | I don't mind throwing more NIC's at the bond on the server, I'm still gonna, this just seems to make sense overall
| |
| 17:32 | I'm gonna go upgrade 10 guys right now, actually.
| |
| 17:32 | bbl
| |
| 17:32 | <gbaman> alkisg and vagrantc, the results are in :)
| |
| 17:32 | we did a larger test today with 15 pis
| |
| 17:33 | and I think a gigabit network...
| |
| 17:33 | 15 pis, booted to login screen in about 1 min, 15 seconds
| |
| 17:33 | which isnt too bad
| |
| 17:33 | they were all started at exactly the same time for the test
| |
| 17:34 | so success, teacher involved is pleased with the results
| |
| 17:34 | willianmazzardo has joined IRC (willianmazzardo!~textual@187.4.15.116) | |
| 17:35 | <gbaman> We are going to test libre office tomorrow all at same time
| |
| 17:36 | * alkisg booted fat clients in 15 seconds with 10.04 + gigabit... but since then boot times have grown bigger | |
| 17:37 | <gbaman> thats impressive :)
| |
| 17:37 | pis do take about a min to boot normally anyway alksig
| |
| 17:38 | <alkisg> They have sd cards, not real fast disks, right?
| |
| 17:39 | Anyways, with gigabit networking you should be fine, like locally booted pis
| |
| 17:40 | <gbaman> yes
| |
| 17:41 | and we are talking about 15 pis booting at a time
| |
| 17:41 | at exactly the same time
| |
| 17:42 | <alkisg> Booting takes about 50 MB, so it's not a big strain on the network
| |
| 17:43 | <ogra> alkisg, fi boot times have grown bigger thats a bug !
| |
| 17:44 | <alkisg> ogra: boot speed was a 10.04 goal, for 12.04 they didn't care as much :)
| |
| 17:45 | <ogra> (my Ubuntu 14.04 XPS 13 boots in 7 sec ... from SSD though ...)
| |
| 17:45 | alkisg, i am one of "they" as stgraber is :)
| |
| 17:45 | <alkisg> My 14.04 needs about a minute
| |
| 17:45 | <ogra> just tell us and file bugs :)
| |
| 17:45 | <alkisg> With the usual 1 tb sata disk
| |
| 17:45 | I'm trying, but I never see developers reply in launchpad :)
| |
| 17:45 | <ogra> ah, yeah, SATA spin up time
| |
| 17:46 | <alkisg> Only bug triagers which are trigger-happy to add tags, but don't actually help...
| |
| 17:46 | * ogra looks at bugs every day ... though my focus is on crazy phone stuff nowadays | |
| 17:47 | <alkisg> Thanks for the chat guys, bbl

| 17:47 | * vagrantc waves | |
| 17:48 | <gbaman> interesting, 45 seconds from SD card, 80 seconds from network?
| |
| 17:48 | for pis
| |
| 17:48 | on gigabit network
| |
| 17:48 | only a single pi
| |
| 17:48 | the teachers timing might have been a little optimistic it seems
| |
| 17:48 | <ogra> gbaman, USB NIC, no ?
| |
| 17:48 | <gbaman> yes
| |
| 17:48 | <ogra> right
| |
| 17:48 | that limits you to 24MB/s
| |
| 17:48 | <vagrantc> gbaman: second boot any faster?
| |
| 17:48 | <gbaman> the pis built in one is, yes
| |
| 17:49 | you want me to reboot it vagrantc?
| |
| 17:49 | <vagrantc> yeah, usb network is ugly slow
| |
| 17:49 | gbaman: or boot a second one
| |
| 17:49 | <ogra> and if it is a shared hub even less
| |
| 17:49 | <vagrantc> gbaman: just to see
| |
| 17:49 | <gbaman> that requires me to go find a pi... one sec
| |
| 17:50 | I was getting this tested remotely in a school quite a distance from me
| |
| 17:50 | via skype :)
| |
| 17:50 | <vagrantc> gbaman: i.e. are two conseqitive boots faster is the basic question i'm getting at
| |
| 17:50 | gbaman: i mean, it's just curiosity, no need to go out of your way
| |
| 17:51 | <gbaman> so you mean vagrantc, once the first one has finished booting, does a second one boot faster?
| |
| 17:51 | or at the same time?

| |
| 17:53 | <gbaman> just occurred to me, I cant actually test it right now, only 1 monitor and 1 ethernet cable
| |
| 17:53 | although I could easily swap the monitor cable, I have a funny feeling swapping ethernet would not go down well :D
