stuartmI should be able to upgrade to mythbuntu (ubuntu) 12.04 via the CD?16:38
tgm4883hmm16:39
tgm4883stuartm, I want to say yes, but I think there may have been a serious issue with that16:39
stuartmcan't do an online upgrade because it requires too much space (much more than previous upgrades)16:39
tgm4883stuartm, where are your recordings stored? IIRC, the issue is that it wiped /var16:40
stuartmnot in /var :)16:40
tgm4883then IIRC it should work. I think that was the only issue16:40
stuartmok thanks16:41
tgm4883stuartm, hold up16:50
tgm4883!bug 99224116:50
ZinnBug 992241 in mythbuntu "Upgrading using the live cd wipes /var/lib/mythtv/*" [Critical, Fix Released] http://www.launchpad.net/bugs/99224116:50
tgm4883That fix should be in 12.04.116:51
tgm4883it's not in the 12.04 release (although you probably have the 12.04.1 ISO if you downloaded it from the website16:51
tgm4883after aug 2316:52
stuartmtgm4883: thanks18:34
IgramulHi, I'm trying to get my remote to work. irw output looks find, I ran mythbuntu-lirc-generate, the config looks fine.18:55
IgramulBut the remote is not working. Any ideas how to proceed?18:55
Igramulfound it: it was a wrong lircd-socket configured in mythtv20:35
whyzzyrdevening. Is there a howto to build a diskless slave backend and front end anywhere?21:38
whyzzyrdthe old docs for ltsp (--mythbuntu etc) don't appear to work any longer21:38
rhpot1991whyzzyrd: as far as I'm aware those docs are considerably out of date21:39
whyzzyrdah, but so was my previously working system.. :)21:39
rhpot1991IMO there is no reason to do diskless anymore, buy a $5 usb drive and be done with it21:39
whyzzyrdI wanted to bump the kernel, but b0rked the whole contraption, so wanted to basically start again21:40
whyzzyrdI suppose you have a point, but I've been doing diskless for some time, as it's less likely to be screwed up by the kids21:41
whyzzyrdironically, it was me that screwed it up though21:41
sabhainwhyzzrd you had a diskless slave backend??21:44
whyzzyrdaye21:44
whyzzyrdnfs back into the one with the disks21:45
tgm4883Is there much of a chance that kinds would mess up a backend system?21:45
sabhainI've been running 3 diskless frontends for several years, and just this past weekend started to contemplate adding a slave backend to my setup.21:45
sabhainprevious to using diskless server, I used to keep the / drive for all the front ends on the core, and get to them via an NFS boot21:45
sabhainusing /boot on a cflash drive21:46
sabhainseems to me that grub2 killed any chance of that working again.21:46
whyzzyrdI suppose if I explain it'd be easier. I had one "master" box, with 3T of disk in and one DVB-S Tuner. I also had a pair of diskless frontends. I wanted a pair of DVB-T tuners, and the frontends had slots (and proximate antenna cables)..21:46
whyzzyrdso both my diskless frontends also became slave backends21:47
sabhaindid you add the backend components/setup from within the booted front end, or was there a way to do it through chroot?21:47
whyzzyrdNext I bought a DVB-S2 card ... and needed a newer kernel than I had. So, I tried a rebuild.21:47
whyzzyrdadded it from within the booted front ned21:47
whyzzyrdinto the overlay fs21:47
sabhainwow!  that's really cool.21:48
whyzzyrdwell, it was when it worked.21:49
sabhainis diskless-server still a real package?21:49
whyzzyrdBecause the frontends had the same DVB-T cards in, the remote controls were even interchangeable21:49
whyzzyrdin any case, I'd actually like to simply rebuild the mythbuntu-diskless boot images, and mount my old overlay onto the top of it.21:50
sabhainwhich version?21:50
whyzzyrdthey were 11.x IIRC21:50
sabhainand now, you're trying for 12.04?21:51
whyzzyrdI need a 3.2 series kernel for the DVB-S2 card to be stable apparently21:51
sabhainoof .. just checked my folder of resources for building the images, and the first 2 links are non-existant.  Wish I had webclipped those.21:52
whyzzyrdit appears that it's all changed, and maybe not for the better as far as it 'just work'ing is concerned21:54
sabhainI last did it on 10.04 LTS.  Last night I built a test system from spare parts (not one of my production units).  I think perhaps I'm going to have to prove I can do it on the offline system first.21:56
sabhainfor me the hardest part was always getting the PXE arguments working and passed correctly by my router to the front ends21:57
sabhainyou're having challenges actually building the ltsp?21:57
whyzzyrdmanaged to get one of my ancient images to go, but I'd rather get a newer kernel into it21:57
whyzzyrdit's building a mythbuntu LTSP that appears to be a problem now.21:57
whyzzyrdthere's no longer the "just build a mythbuntu" image option22:00
sabhainwhyzzyrd have you seen this: http://ubuntuforums.org/showthread.php?t=196781122:01
whyzzyrdyeah, but that'll get me building a whole new way of it working, rather than an image that works the old way :)22:03
sabhainagree .. this is not a good read.  I'm glad I jumped in here when I did.22:04
sabhainwould have waded into a disaster without know it!22:04
whyzzyrdthis sort of thing really dents the wife acceptance factor :)22:05
sabhainyou're not kidding.  And my kids don't know anything different.  They can't understand why they can't go to their friends' house and just cue up a movie.22:06
* sabhain longs for the days of laga22:06
whyzzyrddoes rather look like I'll have to bite the bullet and do iot properly though22:06
sabhain?properly?  .. Properly was with ltsp where you could update all the front ends at once.22:07
sabhain... of course once working, you NEVER update anything, lol.22:07
whyzzyrdI did upgrade from 10 to 11 without great fanfare IIRC22:08
sabhainI went from 8.04 to 10.04 and it was smooth.22:09
sabhainnow I think I want to be on 12.04 for some of the new netvision stuff and better vdpau with the video cards22:09
whyzzyrdmy front end's an atom, so no vpdau, but I've only got SD22:13
sabhainseems like a few people have gotten the images to build out there, but the overlay changes don't stick for some reason.22:16
whyzzyrdindeed, which is a pain22:17
whyzzyrdthough as rhpot1991 noted earlier, putting a $5 USB key in the back and booting off that does seem like a reasonably good option22:19
whyzzyrdit's at least 100% understandable ..22:20
sabhain.. yep .. pendulum swings I guess.  About 4 years ago here someone asked why I was messing around with NFS boot an not using diskless.22:27
sabhainwould minimyth work with a mythbuntu backend?22:30
whyzzyrdcan't see why it wouldn't22:32
whyzzyrduncharacteristically, given it took me so long to make all this fly in the first place, I actually took notes, and backups of the important bits ...22:32
sabhainwhyzzrd: this may give me some hope: http://www.mentby.com/Group/mythtv-users/best-optionshowto-for-diskless-frontends.html22:42
dkeithhi22:50
dkeithnm22:50
whyzzyrdsabhain, that's a reasonably interesting read.22:52
whyzzyrdIf I find some time, I'll bring some more old junk home and build a test setup in my garage22:52
sabhainI'll keep popping in here to see how it goes.  I have my "new-to-me" second hand HD-PVR to play with first, so it might be the weekend before I move on updating LTSP & my Core.22:53
whyzzyrdit'll be longer away than that for me I think :)22:54
whyzzyrdI've got it sortaworkign22:54
whyzzyrdwith an old image I kept for a rainy day, and a 3.0 kernel22:54
sabhainI'm game to try the fat-client thing being discussed here to get over the missing --mythbuntu argument.  But I probably won't spend more than a few sessions trying to get the NFS/Overlay thing working.22:56
sabhainCould be USB drives for me after that.  I'm certain it'll be slower than the LAN though.22:56
whyzzyrdwithout the NFS/Overlay, it's pretty much useless to me..22:56
whyzzyrdUSB drives will be slower than GE lan ..22:56
sabhainand me too .. I have different remotes and varying hardware everywhere.22:57
whyzzyrdI've tried to keep mine sane, but given it's mostly out of our dumpster pile at work :)22:57
whyzzyrdthe TV cards, of course, weren't though ...22:58
