[01:09] <mazda01> anyone know why ubuntu after a fresh install of 10.04 from a usb stick would have a / partition that it's installed on FULL? 23 gb full????
[01:09] <mazda01> oops, wrong channel
[10:34] <nosound> Hi, mythbuntu 10.04 + 0.24 weeklybuilds, in Denmark, using DVB-T, since latest update yday there's no sound on playback of recorded, or live view of, mpeg4 channels... mpeg2 channels still ok with audio... has anyone else got this problem ?, also... does anyone here know when mythbuntu.org is expected to be up again ?
[12:31] <matt1982> hey can anyone recommend a mATX motherboard that I could use with mythbuntu. I am not sure which chipset to get for the gfx to use, ATi, Nvidia or Intel. Looking at some online retailers Nvidia is less and less used in motherboards
[15:00] <Twiggy2cents> anybody know why my mythbuntu server when idling says that it is using ~2.84 GB of 3.00GB memory?  It streams fine and plays fine on it.  It just seems weird.  BTW that is from looking at the mythfrontend status page
[15:02] <rhpot1991> Twiggy2cents: ram isn't free'd up until its needed by something else, nothing to worry about
[15:04] <Twiggy2cents> Thats what I figured...  Thank you
[15:04] <Twiggy2cents> Can mythtv save to two hdd's as one hdd?  Like when one gets full it just goes to the next?
[15:05] <Twiggy2cents> would you just add another path to the save locations pointing to the other hdd?
[15:06] <rhpot1991> Twiggy2cents: which version of mythtv are you running?
[15:06] <Twiggy2cents> 0.23.1
[15:11] <wombo> Twiggy2cents, in that version of mythtv it uses a system called storage groups.
[15:11] <wombo> You can setup multiple storage groups, of which only one recorded TV group is setup by default
[15:11] <rhpot1991> yep
[15:12] <wombo> Mythtv will then automatically balance the load depending on throughput and capacity
[15:12] <rhpot1991> it will then split recordings between the 2 drives
[15:12] <wombo> brilliant
[15:13] <rhpot1991> alternate (old) method is to use LVM, but I wouldn't recommend that with nice things like storage groups around
[15:13] <wombo> yeah SG is a big step up
[15:15] <Twiggy2cents> Thank you.  I just got done reading a wiki about it.  I though I saw what I needed to do when I changed the default storing location.
[15:16] <Twiggy2cents> beh LVM is confusing.  I have Fedora on another computer and its weird to have a physical device location and a virtual device location.
[15:16] <Twiggy2cents> It seems pointless on a single hdd setup
[16:20] <totalanni> g'morning
[16:21] <Matt> Twiggy2cents, on a single disk, yes, LVM is probably an unnecessary abstraction :)
[16:21] <Matt> it's beautiful when you've got a RAIDed system that allows you to add disks and grow the array
[16:22] <Matt> but I'd probably go so far as to say most folk don't run myth on such systems
[16:23] <Twiggy2cents> Yeah It has potential but I think it should of been an option rather than a standard in my single hdd fedora setup
[16:23] <rhpot1991> Matt: LVM is a pain to work with too though
[16:24] <Twiggy2cents> but then again this isnt #fedora so enough about my setup
[16:30] <rhpot1991> Twiggy2cents: eh no worries, not like you are interrupting someone else from getting help
[16:31] <Twiggy2cents> well it seems that I always get in trouble on all the chans I am on because of it being off topic :-D
[16:32] <totalanni> I installed mythbuntu onto a box, when i goto "watch tv"...it just tells me "Please W..." and then goes back to the menu
[16:32] <totalanni> i assume this is because my tuner
[16:33] <totalanni> which is a hvr-950q
[16:33] <tgm4883> !logs | totalanni
[16:33] <Zinn> totalanni: MythTV logs are stored in /var/log/mythtv/   You can use mythbuntu-log-grabber from the Applications menu to automatically post the most relevant logs to our pastebin.
[16:33] <totalanni> ty
[16:33] <totalanni> sec
[16:33] <Matt> rhpot1991: it's not a pain in the slightest
[16:34] <Matt> rhpot1991: obviously you never had to work with evms :)
[16:34] <rhpot1991> Matt: well if one drive goes bad it breaks your entire LVM
[16:34] <rhpot1991> and replaceing a drive was no fun at all either
[16:34] <Matt> this is why you don't put PVs on bare disks
[16:35] <Matt> you put them on raid arrays :)
[16:35] <Matt> using LVM to combine individual disks is just as risky as using RAID0
[16:36] <Matt> you basically multiply the probability of failure with every disk
[16:37] <Twiggy2cents> :( I have to use it to mount partitions on the same hdd.
[16:38] <Matt> Twiggy2cents, there are some good reasons why it defaults to using LVM for local volumes
[16:39] <Matt> mainly because it's a damn sight easier to resize logical volumes than it is partitions
[16:39] <Zinn> Matt: Please watch your language.
[16:39] <Matt> Zinn, appologies :)
[16:39] <Zinn> Hi Matt, something I can help you with today?  I am a bot, use !help to see what I can do.
[16:40] <rhpot1991> Matt: that makes sense
[16:40] <Twiggy2cents> is there a linux program that will move all empy space to the end so it can be one partition?  I had ubuntu at the beginining and deleted it.  I am maxed out at 4 partitions,(1 unallocated), 1 boot, 1 fedora, 1 swap, and 1 empty space.  In a perfect world, I would like the fedora partiton to be combined with the 1 empty space.  Is that possible?
[16:40] <Matt> Twiggy2cents, yes, but backup your data first
[16:40] <Matt> Twiggy2cents, checkout gparted - that'll do what you want
[16:40] <Matt> and there's a version on a bootable iso
[16:41] <Matt> so you can burn a CD, boot from CD, move and resize your partitions, then reboot
[16:41] <Matt> but whenever you're moving data around on the disk like that *backup your data first*
[16:41] <Twiggy2cents> or at least make the lvm system show the last partition(empty space) as part of the fedora partition?  Rather then show it as a mountible location?
[16:42] <Matt> well you can do that too
[16:42] <totalanni> ok
[16:42] <totalanni> while trying to recreate error
[16:42] <totalanni> its giving me something different now
[16:42] <Twiggy2cents> okay I will check out gparted.  I already cloned the hdd from a 320gb to a 1tb hdd.  That was confusing.  I can use the 320 now for my backup I assume
[16:42] <totalanni> (prob because i tried to install the xc5000 fw in /lib/firmware
[16:43] <Twiggy2cents> Matt, would I have to rerun the grub install to update the MBR after messing with gparted?
[16:43] <Matt> Twiggy2cents: if you deleted the last partition, create a new one in the empty space and set it to partition type 8e
[16:43] <Matt> (that's Linux LVM)
[16:44] <Matt> then you can run pvcreate on /dev/sd(that partition)
[16:44] <totalanni> i just ran the log grabber
[16:44] <Matt> then you can use vgextend to add that partition to your existing volume group
[16:44] <Matt> then you use lvextend to grow your logical volume
[16:45] <totalanni> its telling me all inputs in use now
[16:45] <Matt> then you use the appropriate filesystem utility to grow the filesystem; which for ext3 is resize2fs
[16:45] <Twiggy2cents> my system is ext4  would that be the same?
[16:45] <Matt> Twiggy2cents: gparted ought to do that for you *I think*
[16:45] <Matt> Twiggy2cents: but don't quote me on that
[16:45] <Matt> I've not done a resize on ext4, but probably
[16:45] <totalanni> where to i go after i do the log grabber?
[16:46] <Twiggy2cents> I am gonna try the gparted method first due to I still have about 151 GB's of unallocated at the beginning of the drive.
[16:46] <Matt> Twiggy2cents: if you're already using LVM, it's less disruptive to add it as a PV
[16:47] <Twiggy2cents> do you have any tricks for getting the unallocated space at the beginning into a partition?  It says I can only have 4 primary partitons
[16:47] <Matt> Twiggy2cents: that's a DOS partition table limitation
[16:48] <Matt> and unfortunately there's no way around that
[16:48] <Matt> you can have up to 4 primary partitions, or up to 3 primary and 1 extended
[16:49] <Matt> then within the extended partition, you can create multiple logical partitions (I forget how many - might be 8)
[16:49] <Twiggy2cents> Bah so I would be stuck with reorginizing the drive if I wanted to use that.  Would there be anybetter performance with the boot and fedora partitions being at the beginning of the drive?
[16:49] <Matt> yes, basically :)
[16:49] <Twiggy2cents> It seems like it takes a long seek time on opening up some programs every once and a while
[16:50] <Twiggy2cents> So if I moved them would the LVM pick up on the move or would I have to reconfigure it?
[16:50] <Matt> in my own bench tests, I've seen almost double the transfer rate from the starting tracks on the disk compared to the ending tracks
[16:51] <Matt> usually I put /boot at the start of the disk (largely historical, but it's also tiny); followed by swap, where you do want the performance
[16:51] <Twiggy2cents> wow,  I didnt have the problem when on the little 320GB hdd but do on this 1tb 64mb cache
[16:51] <Twiggy2cents> so /boot, swap, fedora , extra space?
[16:51] <Matt> yup
[16:52] <Matt> that's normally how I lay out my disks
[16:52] <Twiggy2cents> okay, and just to revist this question.  What is going to happen to the lvm if I do a major renovation on the hdd tables?
[16:52] <Twiggy2cents> Will it automatically reconfigure, will it even boot?
[16:53] <Matt> LVM doesn't care about partition layout
[16:53] <Matt> it's just data on the disk
[16:53] <Twiggy2cents> okay so its just reading the primary partition and loading that into the lvm accordingly?
[16:53] <Matt> it identifies volumes by a UUID, rather than device name
[16:54] <tgm4883> which is important
[16:57] <Matt> what happens at boot-time is the init scripts run pvscan, which checks each disk and partition for an LVM volume signature, and if it finds one, reads in the UUID
[16:57] <Matt> then is uses that to work out what Volume Groups exist and which physical devices make up each VG
[16:58] <Matt> then it runs vgchange -a y, which activates all volume groups - that makes all logcal volumes available and creates /dev/<VGname>/<LVname> device nodes
[16:58] <Twiggy2cents> okay that sounds easy :)
[17:01] <Matt> Twiggy2cents: have you had a play with pvdisplay, vgdisplay and lvdisplay?
[17:01] <Matt> they show you the physical volumes (usually disks or partitions), volume groups (groups of physical volumes) and logical volumes (carved out sections of each volume group), respectively
[17:02] <Matt> that's a pretty good spot to start when trying to figure out LVM :)
[17:03] <Twiggy2cents> No I have been using the gnome partition manager :)
[17:03] <Matt> ah :)
[17:03]  * Matt is oldschool
[17:04] <Twiggy2cents> Lol it seems pretty straigth forwards with the partition manager, and its in pretty colors and pictures!  Am I missing anything important by using that?
[17:04] <Matt> probably not
[17:04] <Twiggy2cents> okay
[17:04] <Matt> just remember to make a backup first :)
[17:04]  * Matt can't stress that enough
[17:05] <Matt> there's nothing worse than slipping up and hosing your filesystem
[17:05] <Twiggy2cents> yes I am deffinitely doing that.  It took me forever to learn how to set up fedora(ubuntu was my first and only linux up until that point)  I dont want to screw it up!
[17:06] <Twiggy2cents> Well I have to get back to work.  Thanks for the advice!
