| CrystalVoid | if i installed onto btrfs can i do a snapshot of the entire os? or only sub volumes? | 03:47 |
| patdk-lap | what is the difference? | 03:51 |
| patdk-lap | aren't they one in the same? | 03:51 |
| CrystalVoid | i may be mis understanding *first time ever relly spending any time thinking about filesystem things | 03:52 |
| CrystalVoid | what would the command look like ? something like "btrfs subvolume snapshot / snapshot-name" ? | 03:56 |
| patdk-lap | with btrfs, everything is a subvolume | 03:59 |
| patdk-lap | you can view them different ways, like point in time views, if you wish | 03:59 |
| patdk-lap | dunno how flexable they have made it yet | 03:59 |
| patdk-lap | but technically it could even do multible streams from the same base | 04:00 |
| patdk-lap | it's been alittle over a year since I used btrfs | 04:01 |
| CrystalVoid | ahh thanks tho :) it all helps | 04:06 |
| CrystalVoid | any chance you rember how to restore a snapshot? | 04:09 |
| patdk-lap | restore? | 04:09 |
| CrystalVoid | .. if a take a snap shot of something .. then brake it .. how would i go back to that point? | 04:10 |

| slyboots | Hey | 13:50 |
| slyboots | Does anyone know a decent way of manaing LVM and by extension LUN setups on a Ubuntu server? Preferably web/console based with a decent UI | 13:51 |

| patdk-lap | heh, it's simple by hand | 14:19 |
| patdk-lap | but what do you mean by extension LUN setups? you mean iscsi? | 14:20 |
| slyboots | Well more resizing | 14:20 |
| patdk-lap | if you purely want a web system to do that, look at openfiler | 14:21 |
| slyboots | Its fecking harrowing trying to *shrink* a LVM since if you do it wrong you butcher the data | 14:21 |
| patdk-lap | well, that's a given :) | 14:21 |
| slyboots | LUN's are easy | 14:21 |
| slyboots | its just.. I dont like poking LVM's espically resizing when I can help it | 14:22 |

| johna | What if any is the downside of LVM on a server, and conversely what is the upside? | 16:16 |
| qman__ | LVM offers more flexibility than direct partitions at the expense of some minute amounts of space and the overhead of an abstraction layer | 16:17 |
| johna | qman__: thanks, I am new to Ubuntu, I was using Centos, my server died PS problem blew everything, so I am setting up a new server. my current needs are postfix/dovecot & webdav. HW config phenom II, 8Gb, 4 x 1Tb hd. 1st problem how to config HDs, then on to SW. Any advice would be welcome, in fact its desperately needed! TIA | 16:23 |
| qman__ | depends entirely on your load, importance of data vs performance, etc... | 16:25 |
| qman__ | quad core phenom? | 16:25 |
| qman__ | postfix+dovecot is easy to do on ubuntu, I haven't done webdav | 16:26 |

| qman__ | if speed and reliability are more important, I'd do raid 10, if capacity and reliability are important, raid 5 | 16:27 |
| qman__ | regardless of what you choose, I'd do mdraid (it's in ubuntu's setup) | 16:27 |
| johna | qman__: quad core = yes. | 16:27 |
| qman__ | then raid 5 should perform well enough provided you have a half decent disk controller | 16:28 |
| qman__ | AMD 8 and 9 series are good enough | 16:28 |
| qman__ | for four disks at least | 16:28 |
| qman__ | but if you want the most speed, 10 is better | 16:29 |
| johna | qman__: I had thought of adding a 5th as a spare, but the pocket book need to rest. | 16:29 |
| qman__ | most important thing is setting up smartctl | 16:30 |
| qman__ | a couple years ago I lost a raid 5 array when three drives died the same day | 16:30 |
| qman__ | had I had smartctl set up properly I would have gotten a few days warning | 16:30 |
| johna | qman__: would /boot - raid 1, swap - raid 0 , /tmp raid 1, /root raid 5/6, /common raid 5/6 (long term data store) as partitions be reasonable, or would I be better to put rrot and common under LVM. | 16:31 |
| qman__ | that's way more complicated than it needs to be | 16:32 |
| qman__ | unless you plan on actually needing lots of swap, here's what I would do | 16:32 |
| qman__ | on each drive, create one partition ~512MB at the beginning | 16:32 |
| johna | qman__: thanks for the warning about smartctl! | 16:32 |
| qman__ | then one partition the rest of the size | 16:32 |
| qman__ | mirror two of them as /boot, use the other two as swap | 16:33 |
| qman__ | then set up a raid 5 or 10 on the other four big partitions at / | 16:33 |
| qman__ | the reason being | 16:34 |
| qman__ | you're only working with the same four disks | 16:34 |
| qman__ | splitting up partitions like that is only really helpful if you have separate hardware to put them on | 16:34 |
| qman__ | if you want to split up / and your /common, that's fine too, but all that other stuff is just not needed | 16:35 |
| qman__ | and raiding swap is not necessary | 16:35 |
| qman__ | because you just create two swaps, and it will use what is available | 16:36 |

| johna | can I boot into a raid 5, on centos /boot had to be on a single drive or a raid 1 | 16:37 |
| qman__ | you can, though depending on hardware it may not work on the first try | 16:37 |
| qman__ | getting grub to play nice can be a pain, but it can do it | 16:37 |
| johna | OK, so for ease of ?setup/ops? /boot on a raid 1, swap across all 4 drives .... | 16:38 |
| qman__ | good plan | 16:39 |
| johna | I would limit swap to 1 x memory | 16:39 |
| qman__ | I really don't bother with swap as a serious consideration, it's just a stop gap if I run out of RAM | 16:39 |
| qman__ | RAM is so cheap now, it's just not worth the hassle | 16:39 |
| qman__ | 16GB DDR3 is $100 | 16:40 |
| qman__ | so, whatever is convenient extra space in your paritioning scheme, that's what I use for swap | 16:40 |
| johna | qman__: with 8* Gb I don't really swap, but it doesn't cost much to setup. | 16:41 |
| johna | qman__: I think I will split / & /common just because if at some future date I need to install a new opsys I can reformat if needed without affecting the data store. | 16:46 |
| johna | qman__: any suggestions as to sizes, I was thinking /root 512Mb raid 1, 2Gb swap/drive, root (/) 160 GB raid 5, /common "the rest" raid 5. | 16:49 |
| johna | qman__; any preference as to raid 5 or 6, raid 6 was not available on Centos so I have no experience with it. | 16:50 |
| johna | or, going back to LVM, would I be better off I be better off setting up /root and swap and putting everthiong else under LVM | 17:01 |
| johna | or doing what i should have done and read back over the post by qman__ stick to the KISS principle!!! | 17:04 |
| johna | qman__: thanks for all the help, I am sure I will be back for more, have a good weekend! | 17:05 |
| qman__ | johna, /root doesn't really need to be separate for any reason | 17:11 |
| qman__ | unless you meant /boot | 17:12 |
| qman__ | raid 6 adds additional parity at a very significant performance expense | 17:12 |
| qman__ | I would suggest against it with four drives, it's only really worth it if you have 6+ and need two-disk failure protection | 17:12 |
| johna | qman__: my mistake I meant /boot, OK, i will stick to raid 5 I might when funds permit add a spare to the raids, I believe that this is can be done. | 17:14 |
| qman__ | yes, it's pretty easy to do | 17:14 |
| qman__ | fdisk the new drive and then a single mdadm command | 17:14 |

| pdtpatrick1 | Is there a problem with ubuntu and bridge networking? | 23:06 |
| pdtpatrick1 | http://pastebin.com/Yz4bJF8e | 23:06 |
| e_t_ | pdtpatrick1: how did you create the bridge? | 23:10 |
| pdtpatrick1 | e_t_, i installed bridge_utils and then manually edited network/interfaces | 23:11 |
| pdtpatrick1 | restarted networking but it craps out | 23:11 |
| pdtpatrick1 | which is funny because ifconfig shows virbr0 up and working just fine. | 23:12 |
| e_t_ | can you pastebin your interfaces file? | 23:13 |
| pdtpatrick1 | http://paste.ubuntu.com/645578/ | 23:13 |
| pdtpatrick1 | yes i know i did the static settings twice.. i was testing something out | 23:14 |
| pdtpatrick1 | crap .. i think it should be bridge_ports instead of bridge_port | 23:15 |
| pdtpatrick1 | yup that was it | 23:16 |
| TheEvilPhoenix | how can i forward incoming traffic on some port and redirect it to a different port for processing on the same machine with iptables? | 23:17 |
| patdk-lap | hmm, I don't make any bridges in /etc/network/interfaces, always do them differently | 23:18 |
| patdk-lap | TheEvilPhoenix, REDIRECT | 23:18 |
| pdtpatrick1 | how do u usually do yours? | 23:18 |

| pdtpatrick1 | why u setting the mac addy.. i almost thought it was a broadcast at first. Curious | 23:25 |
| patdk-lap | cause, I configured those bridges as if they are network switchs, they are not used on the system itself at all | 23:26 |
| patdk-lap | your binding eth0 to yours, I don't | 23:26 |
| pdtpatrick1 | oh i c | 23:26 |
| pdtpatrick1 | thanks for that | 23:26 |
