| thafreak | what the hell...stupid selinux | 14:20 |
|---|---|---|
| thafreak | centos totally fsck'd my practical final exam | 14:20 |
| thafreak | i spent the whole time trying to figure out why ssh with keys to a centos vm wasn't working | 14:21 |
| thafreak | turned out to be selinux related | 14:21 |
| thafreak | i guess ssh-copy-id from ubuntu to centos didn't set the appropriate context on the authorized keys file | 14:21 |
| thafreak | luckily, i gave them 2 classes to do the exam...and it's mostly automated by scripts | 14:22 |
| thafreak | but still | 14:22 |
| thafreak | stupid selinux | 14:22 |
| * _bbb_ shakes fist at selinux | 15:26 | |
| _bbb_ | setenforce 0 ftw | 15:27 |
| * thafreak always feels bad just turning it off... | 15:50 | |
| thafreak | like saying, this condom sucks, and throw it away mid coitis | 15:50 |
| andygraybeal | thafreak, discretely though, of course :) | 15:51 |
| thafreak | totally asking for herpes...or getting back door'd... | 15:51 |
| thafreak | wait...i think i'm off topic | 15:51 |
| thafreak | or am i... | 15:52 |
| andygraybeal | hah | 15:52 |
| _bbb_ | so apparantly | 15:56 |
| _bbb_ | i have genital herpes | 15:56 |
| andygraybeal | that's okay, everyone else does too. | 15:57 |
| andygraybeal | just don't tell anyone. | 15:57 |
| thafreak | server herpes...i think it's symplex qq | 15:59 |
| andygraybeal | so you guys know about puppet? | 16:00 |
| andygraybeal | i figure i should be using it... or even start learning about it. | 16:00 |
| andygraybeal | it's one of those things where, i think i'm a failure as a small sysadmin | 16:01 |
| andygraybeal | but some of me is like.. eff it.. for craps sake | 16:01 |
| thafreak | i played with puppet | 16:34 |
| thafreak | it's not bad | 16:34 |
| thafreak | never setup a puppet master though...just made single recipes | 16:35 |
| thafreak | i liked the puppet syntax better than chef | 16:36 |
| thafreak | depends on what you want to do i guess...so many tools with lots of overlap | 16:37 |
| thafreak | i also really like fabric | 16:37 |
| _bbb_ | i like turtles | 16:37 |
| * canthus13 meant to go to a puppet presentation at ILF... | 16:38 | |
| canthus13 | I fell asleep instead. :P | 16:38 |
| thafreak | sleep is for the weak | 16:38 |
| * thafreak looks at canthus13 | 16:38 | |
| * canthus13 pokes at thafreak. | 16:40 | |
| thafreak | ouch | 16:40 |
| * canthus13 was saving energy for the afterparty. :) | 16:40 | |
| thafreak | i mean, pfft, that didn't hurt | 16:40 |
| thafreak | oic | 16:40 |
| thafreak | who was there? any entertainment...or just booze? | 16:40 |
| canthus13 | Just booze... and a hovercopter thing. | 16:42 |
| canthus13 | the main entertainment was the hackerspace with lockpicking competitions. | 16:43 |
| thafreak | and...you pick any locks | 16:45 |
| canthus13 | Yep. :) | 16:45 |
| thafreak | you win anything? | 16:47 |
| canthus13 | Nope. | 16:47 |
| * canthus13 can handle simple padlocks but that's about it. | 16:47 | |
| andygraybeal | ah up in cleveland? | 18:27 |
| andygraybeal | thafreak, bro, thanks for the response on puppet :) | 18:28 |
| thafreak | np | 18:28 |
| thafreak | if you can stand ruby code, chef seems to be more popular | 18:28 |
| thafreak | if you can't stand to look at ruby...puppet seems easier to swallow... | 18:29 |
| thafreak | and if you start with just a single puppet manifest file, it's actually not too hard to jump in | 18:29 |
| thafreak | or, if you like python, fabric is cool...basically write code that gets run over an ssh connection to a remote machine | 18:30 |
| thafreak | or :) | 18:30 |
| thafreak | you can use fabric to put puppet manifests on remote machine and then run it | 18:30 |
| thafreak | but anyway...for whatever reason the hotness for the "agile" "devops" type sysadmins seems to be chef | 18:32 |
| thafreak | Anyone try 12.04 lately? server or xfce? (i'll avoid asking about unity, as that's justa can of worms) | 18:35 |
| thafreak | or lubuntu | 18:35 |
| toddc | installing 12.04 server tomorrow night on two machines and have 12.04 unity on 4 machines now so far so good they fixed a lot of the unity bugs | 18:37 |
| thafreak | cool | 18:37 |
| canthus13 | toddc: they got rid of unity? | 18:38 |
| thafreak | YAY!! they updated the qemu-kvm to support librados...sweet | 18:39 |
| thafreak | i was worried for a while it wouldn't make it in | 18:39 |
| thafreak | FYI, raddos is neat... | 18:39 |
| toddc | well there is a gnome 2 option but I have been using unity for a while and got used to it | 18:39 |
| * thafreak tries to change subject off unity | 18:40 | |
| andygraybeal | thafreak, damn bro, that is some crazy information | 18:40 |
| andygraybeal | thafreak, what is librados? i love kvm | 18:40 |
| andygraybeal | goddamn i gotta google this s hit | 18:40 |
| thafreak | i wasted...erm spent, a number of hours...erm weeks...trying to figure out which one i'd like to use best | 18:40 |
| thafreak | so, you hear of ceph? | 18:41 |
| andygraybeal | never | 18:41 |
| thafreak | ceph is a distributed filesystem in the main line kernel | 18:41 |
| andygraybeal | oh awesome | 18:41 |
| andygraybeal | like andrew | 18:41 |
| thafreak | how it works, is it uses object stores, that store dumb blobs of data | 18:42 |
| andygraybeal | AFS | 18:42 |
| thafreak | i dunno the underlying nature of AFS...but from the user point of view, they're probably similar | 18:42 |
| thafreak | well, ceph isn't really ready for prime time yet...BUT, the dumb blob storage part is there | 18:43 |
| thafreak | one thing they built ontop of it is RBD images...which are like NBD (network block devices) | 18:43 |
| thafreak | but the RBD is broken up into chunks, and striped across your cluster of dumb blob storage machines | 18:44 |
| thafreak | so, you can give a VM a disk device that is an RBD drive, and it's data is striped across a bunch of storage nodes for speed/redundancy | 18:45 |
| thafreak | at work, we have 4 kvm nodes, and right now, they use a central NAS for storing disk images...well, I can't reboot the NAS now, not without taking EVERYTHING down | 18:46 |
| thafreak | so i've been scouring the net looking for a more distributed solution, and these rbd images seem like they might be the ticket | 18:46 |
| andygraybeal | where do you keep up with this information? | 18:47 |
| andygraybeal | is there a magazine i should be reading? | 18:47 |
| thafreak | so I'm excited 12.04's kvm has support for rbd...finally something for me to be excited about for 12.04 :) | 18:47 |
| thafreak | uh...nope...i spend LOTS of time on google honestly | 18:47 |
| andygraybeal | wow this is great | 18:48 |
| thafreak | probably 1/3 to 1/2 my day realistically | 18:48 |
| thafreak | very little time to actually work on anything :) | 18:48 |
| andygraybeal | yea, RnD :) | 18:48 |
| andygraybeal | so what kind of network infrastructure would be internal to that file system? would it have to be fiber? | 18:51 |
| thafreak | no | 18:53 |
| thafreak | but most of the people seriously building distributed file systems are always talking about 10gig-e | 18:53 |
| andygraybeal | so gigabit copper is fine | 18:53 |
| andygraybeal | ah ok | 18:53 |
| andygraybeal | shit :) | 18:54 |
| thafreak | yeah, for most normal people, gigabit is still faster than most disk drives | 18:54 |
| canthus13 | gigabit is faster than most drive interfaces. :P | 18:54 |
| andygraybeal | and would there be a redundant switch(es) between this? | 18:54 |
| thafreak | could be i suppose | 18:55 |
| andygraybeal | i guess, which is the next step in total redundancy? | 18:55 |
| thafreak | not sure how multipathing would work like that though | 18:55 |
| thafreak | i don't know if there is such a thing...there's always trade offs | 18:56 |
| thafreak | true redundancy, you'd need multiple geographically separate locations... | 18:56 |
| thafreak | and sync'ing between them usually makes things slow... | 18:56 |
| thafreak | distributed filesystems like this are more meant to scale up in size and speed more than be really redundant | 18:57 |
| andygraybeal | aaah.. i see.. i was headed in the wrong direction | 18:57 |
| thafreak | making it possible to store petabyte size stuff | 18:57 |
| andygraybeal | so... do you back up this monstrosity? or is it it's own backup.. you hope atleast? | 18:58 |
| thafreak | now maybe you could hook something like async drbd to your rbd image and sync it to a remote location too... | 18:58 |
| andygraybeal | is the filesytem taking snapshots like zfs? | 18:58 |
| thafreak | for me, i'm going to make the central NAS be the backup | 18:58 |
| thafreak | well, the storage nodes that store objects, they use an underlying file system | 18:59 |
| thafreak | and they recommend btrfs currently | 18:59 |
| thafreak | but ext4 would work too | 18:59 |
| andygraybeal | yea, btrfs last time i looked wasn't ready for anything | 18:59 |
| thafreak | not sure where you would do snapshotting at... | 18:59 |
| thafreak | it works pretty good in some situations...hopefully it will be ready soonish | 19:00 |
| andygraybeal | yea, what your talking about is way over my head :) it makes me excited though | 19:00 |
| thafreak | me too... | 19:00 |
| thafreak | there's also something called sheepdog, fyi, if you have more than one kvm server | 19:01 |
| andygraybeal | i'm still stuck in user application land.. not so much infrastructure at this point. | 19:01 |
| thafreak | i haven't dug into that too deeply though | 19:01 |
| andygraybeal | i have two kvm servers | 19:01 |
| andygraybeal | i will look it up | 19:01 |
| thafreak | i guess it's not uber fast, but more focused on reliable replication of block devices between nodes... | 19:02 |
| thafreak | so you can live migrate between any of your N nodes | 19:02 |
| andygraybeal | wow nice | 19:02 |
| thafreak | i'll hopefully check it out and this rbd stuff soon | 19:03 |
| andygraybeal | that stuff is very exciting. i might wait a bit till it becomes polished a little, i hope that doesn't make you hate me : | 19:03 |
| thafreak | see which works best | 19:03 |
| thafreak | nah | 19:03 |
| thafreak | i trust the LTS stuff | 19:03 |
| thafreak | so if it's in there, i'll use it | 19:03 |
| thafreak | if I have to build things from source...i tend to avoid it sadly | 19:03 |
| thafreak | so i understand | 19:03 |
| andygraybeal | 8.04 was a bit of a kvm pain :) | 19:04 |
| thafreak | the rbd stuff is in this LTS...and i think sheepdog is too...so i'm assuming they felt it polished enough | 19:04 |
| andygraybeal | awesome, i will try it then | 19:04 |
| thafreak | i used xen still on 8.04 | 19:04 |
| thafreak | actually, I still have one 8.04 xen box running....need to migrate the vm's off | 19:05 |
| andygraybeal | yea, it wasnb't really that long ago | 19:05 |
| thafreak | i wish i had more machines to test on | 19:05 |
| Unit193 | skellat: Your podcast was in the Ubuntu Weekly News. | 19:30 |

| Unit193 | Cheri703: You happen to see something like this http://www.webupd8.org/2012/04/valvle-works-on-steam-for-linux.html ? | 20:00 |
| canthus13 | Unit193: Funny. | 20:02 |
| Unit193 | canthus13: I don't care, but what's-his-name might. | 20:02 |
| thafreak | i've used steam in wine...but i would probably do alot more pc gaming if they actually did port steam to linux | 20:41 |

| canthus13 | Visig0th: That's a rather lame visigoth raid. :/ | 23:21 |
| Visig0th | Sorry, was having client issues.. | 23:23 |
| Visig0th | I shoud've known better than trying to experiment with xchat again after being away from it for so long and having been used to irssi. | 23:25 |
| Visig0th | Its fixed now, so no more jumping in and out. | 23:25 |
| Visig0th | And of course hello, btw. I'm Bradley. I generally go by simply Visigoth, that is without the "0". I'm in SW Ohio. | 23:26 |
