| djveer | Hey guys, i'm getting errors saying "ata3.01: status: { DRDY ERR }" and "ata3.01: error: { UNC }" when trying to boot my ubuntu server. An attempt to fsck the volume gives me "Buffer I/O error on device sda1, logical block 548742" Error reading block... etc | 03:35 |
| djveer | This a corrupted file system? or could there be a hardware problem here, and how do I tell | 03:35 |
| djveer | *? | 03:35 |
| twb | djveer: your disk is dying | 03:41 |
| twb | djveer: go stick it in the freezer, wrapped in a towel, for half an hour. Then take it out and dd the data off it. Then you can attempt to fsck the dd image instead of the dodgy disk. | 03:42 |
| djveer | twb: okay cool thanks for the advice... what dd command would I use? dd if=/dev/sda1 of='filename' bs=1M or something like that | 03:43 |
| twb | djveer: if you have dd_rescue, that would be easiest. | 03:44 |
| djveer | twb: okay, i'll look into it. Can it be done with just the standard dd utility though? | 03:44 |
| djveer | i've never honestly used dd_rescue, so not sure of it's function | 03:44 |
| twb | dd_rescue is just dd with some bodgy patches to make it slow down or speed up when reads fail | 03:53 |
| djveer | okay, good to know | 03:54 |
| twb | i.e. it's designed specifically for your current use case | 03:55 |

| ubuntu_user_01 | my OS hdd is failing and i need to swap it out...i have a raid 6 seperate from that hdd, is it possible to do a fresh install of ubuntu on a new HDD and rebuild or boot the raid 6 post install? | 04:31 |
| twb | ubuntu_user_01: sorry, you have the OS on an un-raided single disk, and a separate RAID 6 array that's used for something else? | 04:35 |
| ubuntu_user_01 | yess | 04:38 |
| ubuntu_user_01 | sorry for the delay | 04:38 |
| twb | ubuntu_user_01: is it md raid? | 04:38 |
| ubuntu_user_01 | yes mdadm raid 6 | 04:38 |
| twb | Are you raid6-ing the disks, or partitions on the disks? | 04:38 |
| ubuntu_user_01 | raid 6 the disks | 04:39 |
| twb | Bummer. | 04:39 |
| ubuntu_user_01 | 8 full hdd in raid 6 | 04:39 |
| ubuntu_user_01 | well thats not good hahaha | 04:39 |
| twb | Otherwise you could easily just put /boot on a second set of raid1 partitions, and move the root partition into the array. | 04:39 |
| twb | Which is what I'd do for a fresh deployment. | 04:40 |
| twb | I *think* GRUB2 can understand a /boot stored on LVM on md RAID now, but I wouldn't want to rely on it. | 04:40 |
| ubuntu_user_01 | can i drop another HDD in and make my failing HDD a raid 1 with the new 1, yank out the failing drive and then rebuild the raid 1 with another new hdd | 04:40 |
| twb | ubuntu_user_01: so you would end up with 10 disks, a raid-1 array of two disks for / and /boot, and the original, unchanged raid6 of eight disks for /srv? | 04:41 |
| ubuntu_user_01 | wait...i think i am raid partitions | 04:41 |
| ubuntu_user_01 | yea | 04:41 |
| twb | That ought to work | 04:42 |
| ubuntu_user_01 | sweet...now i just got to go break down my raid 0 in the hackintosh till i can get some new hdd | 04:42 |
| ubuntu_user_01 | haha | 04:42 |
| twb | You'll need to dance with grub during the transition, so make sure you have a live CD ready, preferably one with mdadm and lvm2 installed in it | 04:42 |
| ubuntu_user_01 | alternate cd comes with both correct? | 04:42 |
| twb | Not in rescue mode, although you can probably anna-install them from the CLI while in rescue mode. | 04:43 |
| twb | I would normally use a hand-rolled rescue image, or the CentOS 5 live CD, or knoppix. | 04:43 |
| twb | IMO that's less hassle than trying to use d-i's rescue mode. | 04:44 |
| ubuntu_user_01 | kk thanks for the help | 04:45 |
| axisys_ | twb: hmm.. so jfs fs gets destroyed if it is external array while the internal disk has the OS which went bad? | 05:05 |
| axisys_ | twb: hmm would be nice if jfs behaved like zfs where i can destroy my OS on internal disk and no worry | 05:06 |
| twb | axisys_: huh? | 05:06 |
| twb | I don't know anything about JFS. | 05:06 |
| axisys_ | ubuntu_user_01's raid6 was on JFS aparently based on his comment on #ubuntu | 05:07 |
| twb | axisys_: surely you mean JFS was on RAID6. | 05:07 |
| axisys_ | twb: that was what he said | 05:08 |
| twb | axisys_: YOU said RAID6 was on JFS, i.e. backwards | 05:08 |
| axisys_ | twb: oops.. yep | 05:08 |
| twb | I don't see why the filesystem would matter. | 05:11 |
| twb | He had his OS filesystem separate from his data filesystem | 05:11 |

| * ttx disappears | 17:11 | |

| kirkland | RoAkSoAx: shouldn't affect your modularity, though | 17:20 |
| RoAkSoAx | kirkland, it should since I'm planing to handle that differently, other than that I'll just merge your change sin mine | 17:21 |
| kirkland | RoAkSoAx: cool | 17:22 |
| kirkland | RoAkSoAx: basically, i'm going to move the config code that builds the list of ISOs to a different file | 17:22 |
| kirkland | RoAkSoAx: different config file | 17:22 |
| kirkland | RoAkSoAx: that only gets sourced if we're in the "Select an ISO" code path | 17:23 |
| kirkland | RoAkSoAx: which necessarily requires network connectivity | 17:23 |
| kirkland | RoAkSoAx: I want to avoid requiring network connectivity for those code paths that don't actually need it | 17:23 |
| kirkland | RoAkSoAx: like "testdrive -u /path/to/local/foo.iso" | 17:23 |
| RoAkSoAx | kirkland, woulnd't it be more user to keep the menu but show "no network connectivity, please insert path to iso"? instead of showing the whole menu? | 17:25 |
| RoAkSoAx | kirkland, I have just uploaded my changes to a branch for you to take a look at: lp:~andreserl/testdrive/module | 17:28 |
| RoAkSoAx | an initial modularization is pretty much done, but It still requires many changes to improve the code basically | 17:29 |
| RoAkSoAx | and I'll probably merge the launch_kvm launch_virtualbox and launch_parallels functions from the executable to the "module" | 17:29 |
| RoAkSoAx | kirkland, there's also a "prueba" script that shows how to use the configparser | 17:30 |
| RoAkSoAx | and I'm creating the ISO list in the "module" instead of creating it in the config | 17:31 |
| kirkland | RoAkSoAx: i'm really slammed all day today, so i won't be able to get to it until tonight | 17:31 |
| RoAkSoAx | so that it is used for both, the command line, and the PyGTK interface in the future to create a manu | 17:31 |
| RoAkSoAx | kirkland, its ok, I'm gonna do some work on it today with the way I was planing to parse the config file, so that you can see all that tonight | 17:32 |

| ttx | https://lists.ubuntu.com/archives/ubuntu-server/2010-March/003906.html | 19:21 |
| kirkland | ttx: sorry, no, haven't gotten to it | 19:22 |
| ttx | kirkland: nothing urgent, just something to keep an eye on, I guess :) | 19:23 |
| ttx | I'll do a few tests when I'll be back on Friday. | 19:23 |
| kirkland | ttx: yeah, agreed | 19:26 |
| ttx | kirkland: I experienced sluggish performance under kvm recentely, and it might have been when I did iso testing over qcow2 images. | 19:27 |
| smoser | jdstrand, i just opened bug 544435 i believe its a problem with app armor profiles for libvirt | 19:39 |
| a|3x | hi | 19:52 |
| a|3x | when i run posix_getpid in php i get pid of apache process, why is that? | 19:52 |
| joschi | a|3x: probably because you're running mod_php | 19:58 |
| a|3x | joschi: would it be possible to have apache start different process for each page request? | 20:00 |
| joschi | sure. run php with mod_cgi or suphp | 20:01 |
| joschi | but this means a certain performance hit | 20:01 |
| joschi | normally you want to avoid that | 20:01 |
| a|3x | thats how its done on centos i believe | 20:04 |
| a|3x | the problem is i have a long polling app and i would like to prevent clients from long-polling more than once | 20:05 |
| a|3x | to do that i was planning to use pid checking | 20:05 |
| a|3x | is there any other way to do it? | 20:05 |
| joschi | why not just check a cookie or (more error-prone) the ip address before starting your expensive calculations? | 20:09 |
| a|3x | what if they are behind a nat | 20:09 |
| joschi | then cookies will still work… | 20:10 |
| a|3x | i have non-browser client apps i and would really like to keep them simple and not require cookies | 20:10 |
| a|3x | plus, cookies can be hacked | 20:10 |
| a|3x | actually, this is more of a licensing issue rather than calculation | 20:12 |
| joschi | how would knowing the process id of your php process prevent that in any way? | 20:12 |
| a|3x | lock mysql db lock, get pid in database next to key they provided, see if that process is still alive, if yes, return with key already used error, else save pid, unlock lock, go on | 20:14 |
| a|3x | i could use the db lock for that but i need it for efficient long-poll | 20:16 |
| a|3x | i could set flags in the db but what if the process dies and the flag never gets reset | 20:16 |
| a|3x | how big of a performance hit is it? | 20:17 |
| joschi | the php binary will have to be loaded for each request | 20:17 |
| joschi | since it's in the cache after the first run, at least it doesn't have to be read from the disk every time | 20:18 |
| joschi | a|3x: just try it | 20:18 |
| a|3x | the question is, after each long-poll event i am going to have everybody requesting it again all at the same time | 20:19 |
| a|3x | question: how much of a hit it will be when 100 php processes start all at the same time | 20:20 |
| a|3x | compared to what i have now | 20:20 |
| a|3x | that is mod_php | 20:20 |
| joschi | 100 * size of a single php binary | 20:21 |
| joschi | do your maths ;) | 20:21 |
| a|3x | how does mod_php work? | 20:22 |
| a|3x | fork? | 20:23 |
| a|3x | no wait | 20:23 |
| joschi | a|3x: the interpreter is embedded in the apache processes. that's why you only see apache's pid. no forking is done on a request. | 20:27 |
| a|3x | would it be possible to see if a particular php script is still executing within some apache process? | 20:29 |
| a|3x | unique id of some sort maybe? | 20:29 |

| RoAkSoAx | kirkland, is it really necessary to load multiple config files in testdrive? | 20:54 |
| kirkland | RoAkSoAx: yes; talk to hggdh | 20:54 |
| RoAkSoAx | hggdh, ping | 20:54 |
| RoAkSoAx | kirkland, ok, because I really don't see the point of having multiple config files :) | 20:54 |
| hggdh | RoAkSoAx, pong | 20:55 |
| RoAkSoAx | hggdh, is it really necessary to have multiple config files for testdrive, why? | 20:56 |
| hggdh | RoAkSoAx, we need to be able to test different scenarios -- for example, no network connectivity | 20:56 |
| hggdh | or different memory allocations | 20:56 |
| hggdh | etc | 20:57 |
| hggdh | RoAkSoAx, you mean the successive loads? | 20:57 |
| RoAkSoAx | hggdh, yeah | 20:57 |
| hggdh | RoAkSoAx, they do not hurt -- and allows one to only change what is needed | 20:57 |
| hggdh | for example, I usually base mysefl on /etc/testdriverc, and only add my own changes | 20:58 |
| kirkland | RoAkSoAx: basically, we need 2 ... on distro level set of defaults | 20:58 |
| kirkland | RoAkSoAx: and 1 local one for users to override those | 20:58 |
| kirkland | RoAkSoAx: various people "complained" about where that local one was located | 20:59 |
| kirkland | RoAkSoAx: I thought ~/.testdriverc made perfect sense, but then some people wanted in ~/.config/ and other newfangled locations | 20:59 |
| kirkland | RoAkSoAx: so it's best to just create one process for sourcing a config file, and pass that process an array of locations, in order | 21:00 |
| RoAkSoAx | kirkland, hggdh, uhmmm ok, because I was thinking on doing something like if it does not exist in ~/.testdriverc use the one in ~/.config/ if not, use the default in /etc/testdriverc | 21:00 |
| kirkland | RoAkSoAx: that's not how traditional Unix configs work .... | 21:00 |
| hggdh | RoAkSoAx, I would rather first source the default in /etc/, *then* whatever the user wants | 21:00 |
| kirkland | RoAkSoAx: the traditional Unix config process is a) first source a global config | 21:00 |
| kirkland | RoAkSoAx: b) then source local configs | 21:00 |
| kirkland | RoAkSoAx: please don't go changing this sort of core testdrive functionality | 21:01 |
| kirkland | RoAkSoAx: that part is there for a reason ;-) | 21:01 |
| hggdh | heh. kirkland stated it more nicely | 21:01 |
| RoAkSoAx | kirkland, yeah I just trying to figure out the sourcing of config files since I'm using configparser for that functionality | 21:01 |
| kirkland | RoAkSoAx: right ... so for that, just concatenate all of them together | 21:02 |
| kirkland | RoAkSoAx: and then run the conf parser across it whole blob | 21:02 |
| kirkland | RoAkSoAx: assuming that later variables overwrite earlier ones | 21:02 |
| hggdh | and catenate them in the correct order ;-) | 21:02 |
| kirkland | RoAkSoAx: right, what hggdh said ;-) order matters! | 21:02 |
| RoAkSoAx | kirkland, i was either thinking on having something like "testdrive-globals" and testdrive-locals and they *had* to be different and nto override, but I guess that we should be able to override in local config a global variable, correct? | 21:03 |
| hggdh | correct | 21:03 |
| hggdh | the global gives the user sane defaults | 21:03 |
| hggdh | the user config can be as messed up as the user wants, but the global *has* to be sane | 21:03 |
| kirkland | RoAkSoAx: the key being that ***we*** get to change the globals, but ***users*** get to override them with whatever they want | 21:04 |
| hggdh | ideally, nobody will ever need to change /etc (heh, at least I can hope) | 21:04 |
| RoAkSoAx | hggdh, kirkland ok so, now a python programming question: is it possible to for example do something like: var = KVM_ARGS, then pass that var to a function, and in the function do something like self.var = "-usb" where self.var should actually be self.KVM_ARGS | 21:06 |
| RoAkSoAx | so to the function I can pass functio(var,value) | 21:07 |
| RoAkSoAx | and var is an attribute in a class | 21:07 |
| RoAkSoAx | set_function(self, var, value)self.var = value | 21:07 |
| RoAkSoAx | something like that? | 21:07 |
| hggdh | so you are actually defining a class, and heper methods in it | 21:07 |
| hggdh | as long as the helper methods are in the class, no problem | 21:08 |
| hggdh | I was, in fact, thinking of setting all the config in a class, and passing it to the emulator to be used | 21:11 |
| RoAkSoAx | hggdh, http://paste.ubuntu.com/399537/ | 21:13 |
| RoAkSoAx | hggdh, how can I make that self.var = value, if var is a variable, but should refer to a varibale in the class instead of to the variable var | 21:14 |
| RoAkSoAx | idk if you understand me :) | 21:14 |
| hggdh | RoAkSoAx, easier to have all the attributes in the class | 21:16 |
| hggdh | so that you can just do testdrive.mem=<value> | 21:16 |
| RoAkSoAx | hggdh, http://pastebin.ubuntu.com/399538/ | 21:18 |
| RoAkSoAx | hggdh, i actually modifying the attributes of the class from the main(), however, I'd rather have a set_values class to be able to set the value to a specified var so that I dont have to do it from main | 21:19 |
| RoAkSoAx | because IIRC, it is better to modify the attributes of a class from class functions and not from main, correct? | 21:19 |
| hggdh | RoAkSoAx, opinions vary there ;-) I personally do not like a generic setter like this, makes following the code harder to understand | 21:22 |
| hggdh | if this was an extremely complex programme, then (probably) yes; but you are already using configparser... | 21:23 |
| hggdh | and, BTW, it is better -- following you example -- to do if x: ... elif y: .... elif z: ... | 21:23 |
| hggdh | may be ugly, but such is life | 21:24 |
| RoAkSoAx | hggdh, haha indeed, but it would be better that way in my opinion, that's why Im wondering if theres a way to do that | 21:24 |
| hggdh | and yes, whenever possible, modify class attributes via helper methods | 21:24 |
| hggdh | most probably there *is* a way. Not sure it is worth your time (right now) | 21:25 |
| hggdh | also -- in the helper methods you would probably add syntax and semantic, and whatever, checks | 21:25 |
| RoAkSoAx | hggdh, ok then, since this is just first modularization i guess I will stick to if if if :) | 21:26 |
| hggdh | for example, the memory size is expected to be an integer, greater than zero and less than <memory available>, expressed in Megas | 21:27 |
| hggdh | so 384 == 384Mbytes | 21:27 |
| hggdh | (of course, this is a simple example, but you could have more stringent checks for, say, URLs) | 21:28 |
| RoAkSoAx | hggdh, kirkland ok. The config loading is done and should work with various configs. the only thing would be that each user will have to add [testdrive] in the config file | 22:03 |
| RoAkSoAx | kirkland, hggdh_ lp:~andreserl/testdrive/module, just pushed my latest changes | 22:15 |

| mod | hey all | 22:44 |
| Burgundavia | kirkland-suds, ripping out my hair for last minute Ubuntu book stuff. Is byobu seeded by default anywhere? | 22:45 |
| mod | is it generally true that if I am running RAID 1 with two drives, I should be able to pull one drive and mount it stand alone? | 22:45 |
| kirkland-suds | smoser: can you see ESSID sbsoap ? | 22:45 |

| smoser | no. i've never seen it. | 22:45 |
| kirkland-suds | smoser: okay, i'm rocking now | 22:46 |
| Burgundavia | kirkland-suds, specifically, it is seeded on the Ubuntu server/desktop/netbook cds? my browsing says no | 22:46 |
| kirkland-suds | Burgundavia: it's a recommends of screen | 22:46 |
| kirkland-suds | Burgundavia: actually, it is, as of Karmic | 22:46 |
| kirkland-suds | Burgundavia: fire up a Lucid desktop ISO (by Testdrive, perhaps, and you should be able to open a terminal on the LiveCD and just run 'byobu') | 22:47 |
| Burgundavia | kirkland-suds, no kvm on this laptop. and now I feel stupid. I saw that dependency chain and for some reason it didn't connect in my mind | 22:48 |
| Burgundavia | thanks | 22:48 |
| kirkland-suds | Burgundavia: Testdrive works with VirtualBox too ;-) but yeah, it's seeded | 22:48 |
| kirkland-suds | Burgundavia: glad to hear byobu's earned a mention in your book | 22:48 |
| kirkland-suds | Burgundavia: what book is it? | 22:48 |
| kirkland-suds | mathiaz: screaming through the langpacks now | 22:49 |
| Burgundavia | kirkland-suds, official ubuntu book, the command line chapter | 22:49 |
| kirkland-suds | Burgundavia: cool ;-) | 22:49 |
| kirkland-suds | Burgundavia: poke me if you want a byobu deep dive some time; happy to show you the advanced features if you like | 22:50 |
| Burgundavia | kirkland-suds, for the next edition of the server book, we should probably do something, but that isn't my baby. | 22:51 |
| Burgundavia | but thanks, yes | 22:51 |
| kirkland-suds | Burgundavia: sure thing; is that Kyle Rankin's book? | 22:51 |

| RoAkSoAx | hggdh, tou mean spaces for def and tabs for everything else? | 23:23 |
| hggdh | RoAkSoAx, no, actually one should use *either* spaces *or* tabs in a Python source, but not both (PEP 8 highly recommends spaces) | 23:25 |
| hggdh | in my vi edit of the source, everything seems to be on the same column (because my vi is configured to \t == 4 spaces) | 23:25 |
| hggdh | RoAkSoAx, bye either/or, I forgot to add -- but not both | 23:26 |
| hggdh | my, my, am I writing bad today or what? | 23:26 |
| kirkland-suds | hggdh: RoAkSoAx: but I *strongly* prefer tabs and tabs only! | 23:27 |
| hggdh | RoAkSoAx, the master's voice ;-) | 23:28 |
| kirkland-suds | two reasons: a) 1 tab = 1 byte, b) anyone can configure their editor to represent a tab as as much (or as little) whitespace as they like | 23:28 |
| maxb | a) is largely irrelevant in the face of disks, bandwidth and compression technology of today | 23:29 |
| hggdh | kirkland-suds, as long as it is either/or (but not both) Python feels good... | 23:30 |
| RoAkSoAx | kirkland, hggdh ok, better yet, I love using tabs for coding | 23:30 |
| maxb | b) is a noble goal which starts to fall apart once questions of where the right margin is, and how long statements should be wrapped, enter the picture | 23:30 |
| RoAkSoAx | hggdh, kirkland-suds NAyways, just ping if somethings is need, Call of Duty MW2 awaits me :) | 23:31 |
| RoAkSoAx | later | 23:31 |
| maxb | But really, so long as no-one mixes both in a single file, that's a good start | 23:31 |
| hggdh | maxb, yes indeed, and a lot of hard-core old coders (see coreutils, for example) are moving out of \t | 23:32 |
| * hggdh does not care, as long as it is only one of them | 23:33 | |
| hggdh | ok. Time to get the grill | 23:33 |
| kirkland-suds | hggdh: agreed | 23:37 |
