| itomas | hello, could anyone help with a problem with a thin client not booting due to nbd_server problems? | 10:01 |
|---|---|---|
| itomas | thx | 10:01 |
| alkisg | stgraber: please do the following changes to the ltsp packaging: | 12:27 |
| alkisg | * debian/ltsp-client-core.install:client/initramfs/hooks/ltsp usr/share/initramfs-tools/hooks | 12:27 |
| alkisg | - debian/ltsp-client-core.install:client/initramfs/scripts/ltsp_nbd usr/share/initramfs-tools/scripts | 12:27 |
| alkisg | - debian/rules:cp $(CURDIR)/client/initscripts/ltsp-setup $(CURDIR)/debian/ltsp-client-core.ltsp-client-setup.init | 12:27 |
| alkisg | ...we won't be using ltsp_nbd and ltsp-setup anymore :) | 12:27 |
| alkisg | (and if vagrantc wants he can completely remove ltsp-setup) | 12:27 |
| alkisg | Ah and: - rules:dh_installinit --name=ltsp-client-setup --no-start -u"start 32 S ." | 12:28 |
| stgraber | alkisg: ok, I'll have a look | 14:13 |
| stgraber | alkisg: so should I remove all of these you listed above? | 14:50 |
| alkisg | stgraber: yes | 14:51 |
| alkisg | The line with the star * is a modification | 14:51 |
| alkisg | hooks/ltsp_nbd renamed to hooks/ltsp | 14:51 |
| stgraber | alkisg: right, I did that one already I think (in the latest PPA build) | 14:51 |
| alkisg | So the known problems for now are: | 14:52 |
| alkisg | 1) broken default SCREEN_07, I'm fixing it now, | 14:52 |
| alkisg | 2) no nbd-proxy wrapper, will do that next, | 14:53 |
| alkisg | 3) borked shutdown, we'll need again upstart jobs for reboot/shutdown, but not the old ones, new ones to do nbd-client -d; echo o > sysrq trigger etc | 14:53 |
| alkisg | So that no nbd-server processes are left on the server | 14:53 |
| alkisg | As now that nbd-server is not started from inetd, it takes 2 hours for the connections to get killed | 14:54 |
| stgraber | ok, I can restore the old ones and add nbd-client -d | 14:54 |
| alkisg | Right, although it would be nice if they could somehow wait a bit until the ssh + epoptes connections are closed, I'll see if I can find a clean way for that | 14:55 |
| alkisg | Killing epoptes should do it, not sure about ssh | 14:56 |
| alkisg | pkill -f '^epoptes-client \+m' | 14:58 |
| stgraber | alkisg: http://paste.ubuntu.com/841781/ | 15:02 |
| stgraber | oops | 15:02 |
| stgraber | http://paste.ubuntu.com/841784/ | 15:03 |
| stgraber | /dev/mapp will be replaced by /dev/nbd btw | 15:03 |
| stgraber | http://paste.ubuntu.com/841786/ | 15:04 |
| alkisg | stgraber: hmmm if nbd-proxy is killed, then nbd-client will cause a disk access error, no? | 15:04 |
| stgraber | probably indeed, I guess I'll need to move it to a separate kill after nbd-client | 15:05 |
| alkisg | Also, exec reboot won't work unless you cache it first, better use the REISUB magic | 15:05 |
| alkisg | And I'm using `exec -a` to run epoptes-client, so killall won't work, please use the pkill I wrote above | 15:05 |
| alkisg | echo o > /proc/sysrq-trigger | 15:06 |
| alkisg | I've tested that that works even without a root nbd connection active | 15:06 |
| stgraber | alkisg: http://paste.ubuntu.com/841792/ | 15:08 |
| alkisg | I think killall isn't available in thin chroots, let me see if I have one... | 15:09 |
| stgraber | alkisg: I guess these two should be moved upstream actually and applied to the overlay at boot time | 15:09 |
| alkisg | stgraber: ah, yes, right | 15:09 |
| alkisg | So leave them to me, I'll put them to init-ltsp.d/common | 15:09 |
| alkisg | or /ubuntu, better | 15:09 |
| stgraber | alkisg: because of an overlayfs bug, you'll need to call 'initctl reload-configuration || true' after writing the jobs to /etc/init/ | 15:11 |
| stgraber | alkisg: or actually, after doing any change to /etc/init | 15:11 |
| alkisg | stgraber: err why? It appears to work fine so far | 15:11 |
| alkisg | We do that in the init=/sbin/init-ltsp phase, right? | 15:11 |
| stgraber | ah right, doing it before starting init works indeed, sorry ;) | 15:12 |
| alkisg | :) | 15:12 |
| stgraber | the bug only appears when init is already started | 15:12 |
| alkisg | Yeah I would worry if we were to do that | 15:12 |
| alkisg | So once I commit the default screen fix (really soon), ltsp will be bootable again, so a new package will be nice. | 15:13 |
| stgraber | ok, just ping me when you need it | 15:13 |
| alkisg | ty | 15:13 |
| alkisg | stgraber: I fixed many problems, I think it's time for a new package if you please. | 16:42 |
| alkisg | Next goal, nbd-proxy-wrapper :) | 16:42 |
| stgraber | alkisg: ok, uploading one now | 16:43 |
| alkisg | ty | 16:43 |
| stgraber | alkisg: next time you push something to trunk, can you do "bzr tag current --delete" before "bzr push"? | 16:43 |
| stgraber | alkisg: current shouldn't exist in the LP branch, it's just a local tag I use for snapshots ;) but it requires a commit to drop it | 16:44 |
| alkisg | Sure | 16:45 |
| alkisg | In about an hour, along with the nbd-proxy wrapper script | 16:45 |
| stgraber | alkisg: uploaded | 16:48 |
