Both server and clients rebooted due to power outage since the last time. Odds of cosmic rays hitting the exact same bits in RAM to cause the exact same issue a week apart are poor enough that I think this is a bug. Anyone have any ideas what might be causing it?

What exact base system,with what ltsp package installed on top of it,32-bit,64-bit,fresh install/update from_?,,,and update procedure after initial install? I am guessing this is not for example an initial k12ltsp-EL5 install, from the K12LTSP installation cd's/dvd? Has this occurred from the get go on the ltsp installation onto this server? Also are you using using plug and play switches that these clients are connected to.In other words from ltsp server to client? Have you tried a different switch(s) on this setup? Could you explain better detail if this happens on multiple clients with exact same errors being thrown in the server logs?

IIRC, that is the very old LTSPv4 which did not have remote USB storage support. LTSPv5 supports ltspfs for remote USB storage. https://fedorahosted.org/k12linux/wiki/RHEL5Server Years ago I made this incomplete and experimental LTSPv5 for EL5. ltspfs remote USB wouldn't work because it lacks fuse kernel modules. In any case EL5-based LTSPv5 was not supportable because of several missing pieces in the base distribution. https://fedorahosted.org/k12linux/wiki/2011FundDrive https://fedorahosted.org/k12linux/wiki/EL6Status Please follow the development of K12Linux EL6 which aims to make LTSPv5 fully supported on EL6 (CentOS6 isn't released yet). K12Linux EL6 will be a LTSP distribution with updates through the year 2017. In a few days I will be releasing the first private beta of K12Linux EL6 to the 14 project sponsors. Currently ltspfs is broken on K12Linux EL6. I am attempting to fix it before the private beta. https://www.redhat.com/mailman/listinfo/k12osn Please join this mailing list. A great many K12LTSP and K12Linux users are on this list.

LTSPv5 supports ltspfs for remote USB storage. > The last release of K12LTSP, which was LTSP 4.2 on Centos 5, does support USB storage at the clients, quite well actually. However, if memory serves, the permissions on /dev/fuse would sometimes change to 600 and USB devices on the clients would stop working. I think a change to some udev rule was necessary to keep a reboot from resetting the permissions on /dev/fuse, although I don't recall the specifics.

This is for straight multi-page text PDFs for example. Any recommendations on how to speed up printing?

Thus a good reason to have a fairly automatic tool for a running system to build new kernels for clients when they become available.

The short answer is: to buy time. First, it looks like Fedora 15 will be a show-stopper for LTSP on Fedora. I need to upgrade from Fedora 13, so 14 is the only thing I can upgrade to. I have already gotten Warren's LTSP beta working on a Fedora 14 laptop with only a few tweaks, so upgrading my server buys me another 6 months of so before having to make a major decision about where to jump after Fedora 14. I have liked Fedora because I like getting new functionalities that come with newer versions of applications. For example, when OpenOffice 3.0 came out, it included support for the newer Microsoft file formats eg. .docx, .pptx etc. At work our CentOS system was stuck with OpenOffice 2.4 for a very long time, which was a major inconvenience in this MS-dominated world. While Fedora's cutting edge has sometimes broken things, in recent releases, my experience has been that they get fixed quickly (most of the time.) Secondly, it looks as if staying with LTSP means abandoning the GNOME desktop, because of GNOME3. Or, abandoning LTSP, so I can use GNOME3. I won't rule out either until I get a chance to try GNOME3 for myself. Thirdly, I currently have a 32-bit ThinClient that is 3 years old, and a 64-bit server. LTSP is good because it makes it possible to accommodate different architectures on client and server. But, if I spring for a 64-bit client, suddenly many options open up. For example, run a 64-bit ThinClient as a diskless lean-client, booting an OS image, and mounting home directories remotely from the server. Or, run some sort of remote desktop protocol (eg. rdesktop) on the thin client and leave most of the work on the server (my preference). Finally, there is the eventual replacement of X11 with Wayland. If I had even a clue of what this implies, my choice of Linux distro and thin client model would be compatable with the eventual phase in of Wayland.

It has OpenOffice 3.2.1, is that adequate? I'm experimenting now with building Fedora 14 /opt/ltsp/i386 on EL6 server. Given that Fedora 14 has an optional non-PAE i686 kernel with nbd already built in, it might be a decent short-term solution until we figure out the most sustainable long-term solution.

It will be i686, non-PAE kernel with nbd, so network swap may work. I haven't tested nbdroot. The same private beta download site has completely untested Fedora 14 ltsp-server. I made some theoretical tweaks that were needed, but haven't tested it. I do not consider this to be an acceptable long-term solution for EL6, but if you need more thin client hardware compatibility *TODAY* this is a convenient stop-gap option for K12Linux EL6 admins.

A single page of text from notepad prints fairly quickly. The problem seems to focus around PDFs I believe as those are the only larger documents I've printed. > You might also run top locally on the client while something is printing > to find out if the client is CPU/memory bound (ex: swapping) etc. I sent a 200 page PDF (with some images, total size of the PDF 7 MB) and ran top. What I saw, over the *17 hours* it took to print 100 pages before it just crashed, was the cpu on the thin client not going over 2% and no swap being touched. It looked like it was printing a page every 10 minutes or so, and then towards the last few pages the CPU usage went up to 99% and then back down to zero once it was finished. The process was the jetdirect one I believe (don't have the file in front of me). So I'm not quite sure what the issue is. The thin client is a Pentium 4 2.6 Ghz machine with a gig of RAM.

Remember, everything is running on the server, not the client. So a text file prints quickly but a complicated pdf fails. So some things to look at are: what is the server using resource wise just before the failure? sysstat is a tool to monitor system usage. It can be tweaked in /etc/cron.d to run more frequently than every 10 minutes. I would suggest testing with a less complicated (i.e. shorter) pdf. Make a page or two in openoffice or extract a few pages from the 200 page monster and try again. pdftools are a commandline option as well as just printing a few pages. 17+ hours sounds like a memory shortage to me. Sysstat will show disk usage in terms of swapfile activity. Oh. The tool to view graphs of sysstat data is called sar. Uses java and outputs really useful graphs. excellent tool!

Message-ID: <1309178968.20353.65.camel@hi2.wc235.k12.il.us> Joseph, I just happened to look at your initial post here in regards to your Laserjet printer being so slow. I did not pay close enough attention the first time i read it, I guess. Seeing now that you have this printer attached via an parallel port cable this is probably almost to be expected in regards to print out speed of pdf's. Does this old printer provide an usb port by chance? If so,,this would speed up the print spool considerably. I am guessing the printer is old enough an usb interface was not thought of..:) You should try upgrading the printer driver to the hplip driver (from the foomatic you have listed) and you would see a tiny bit of performance increase as the printer sits now. Let us know your findings.

I just upgrade a F13 LTSP system to F14 using the http://www.dageek.co.uk/ltsp/ltsp.repo courtesy of Gavin Spurgeon and did not have any issues. I have not upgraded the chroot yet, but the server side works great. Definitely don't waste any time on F14. For me KDE4 support is a must. My users all run it on F14 now and do not want to "downgrade" to Gnome 2 :) That being said I tried KDE in EL6 it and it seems to work as well in LTSP as could be expected given that not everything works properly even without LTSP! There is something screwy with phonon as I get a boatload of "Unable to use the GStreamer Multimedia Backend: The shared library was not found." messages. Also, the normal fusefs client filesystem stuff works fine, in the sense that the client media is mounted on the server, but there is no indication in KDE that this has happened via tie-in to the device notifier etc. That is no different from previous K12Linux, though it would be nice to have.

It allows us a stop-gap solution if the i686 PAE kernel is not bootable on your client. The F14 kernel is i686 without PAE, and includes the nbd.ko kernel module allowing clients with maybe 128MB RAM to operate. EL6 chroot lacks nbd.ko so network swap doesn't work, meaning it probably needs 256MB+ RAM. It is a goal to provide a i686 non PAE kernel, but I haven't yet decided what is the most sustainable way of doing so. > > For me KDE4 support is a must.

Are those annoying pop-ups? I know almost nothing about KDE's stack and the people I can ask at Red Hat for help are unable to help me, so I probably can't find the fix for KDE issues. > > Also, the normal fusefs client filesystem stuff works fine, in the sense > that the client media is mounted on the server, but there is no > indication in KDE that this has happened via tie-in to the device > notifier etc. That is no different from previous K12Linux, though it > would be nice to have. > I think Debian has a hook to notify KDE somehow. It's already on the TODO List as a low priority.

It helps to demonstrate to the global community the diverse geography and people who benefit from K12Linux. https://fedorahosted.org/k12linux/wiki/2011FundDrive Currently we have pledges of $2,630.79 from 24 Donors in 9 Countries. James Bergsten has issued a new matching challenge to the K12Linux community. If four NEW contributors pledge a maximum of $50 each totaling a minimum of $185 by July 7th, then he will contribute a matching $185 in support of K12Linux development. This means we will reach our $3,000 goal for the 2011 year, and this fund drive will be completed. Please write to me directly if you would like to make a contribution.

That leaves us with 3 more pledges to end this fund drive, and to enable the beta to go public later this month (after I fix a few more bugs). Warren
