11:01.27ChoHagFucking open source fucking 'support'.
11:01.40ChoHagNot even 3 complete questions before "What are you trying to do?"
11:01.51ChoHagaka "You're doing it wrong."
11:49.58morsingOpenSource just doesn't work. When will people learn
12:06.51wethrinYes, Postfix is such a terrible mailserver. And Apache such a terrible web server. etc. etc. :)
12:19.24morsingIndeed
12:58.55*** join/#gllug dick_turpin (~peter@host217-34-163-30.in-addr.btopenworld.com)
13:18.25ChoHagSo apparently sudo has the shittest command string parsing routine known to man.
13:23.00dick_turpinmorsing: Why is electricity lethal to carbon based lifeforms?
13:24.15morsingdick_turpin: Because it uses electricity to control muscles and as signalling within the brain
13:26.07dick_turpinmorsing: So what you're saying is if you had all your muscles removed you can survive shoving a screwdriver in the plug socket?
13:26.44morsingSomething like that
13:28.04dick_turpinmorsing: Please try it and send photos
13:28.32morsingWeirdo
13:28.46morsingdick_turpin: Someone already trying it in the Tate
13:29.15dick_turpinI don't use sugar?
13:33.59ChoHagwtf! I don't think centos understand what 'minimal' means.
13:35.24ChoHagThe minimal distribution includes support for bridged networks, lvm, firewall, ssh, email and software raid.
13:35.34ChoHagAnd that's just what's considered 'Most Important'.
13:36.07ChoHagAt least I assume so. Their documentation is quite minimal. There's just a list of packages under the title 'Most Important Packages and Applications'.
13:37.00morsing? I don't understand, are you complaining they have too much or too little included in minimal?

17:22.06toxboiIs there any disadvantage of mounting NFS using intr option?
17:22.24toxboiOne of the server is strangely behaving where NFS becomes unavailable (probably a NIC issue) and we need to hard reboot the server.
17:23.42toxboiI'm trying to diagnose it but can't do much as the system becomes unstable (yes unfortunately many things are dependent of NFS).
17:52.12*** join/#gllug Armand (~martin@87-194-165-154.bethere.co.uk)
17:59.38morsingtoxboi: Which kernel? I believe intr is no longer supported, how ever, it is definitely the way to go, and no, there are no disadvantages
17:59.52morsingtoxboi: The Linux crowd are just morons...
20:25.56*** join/#gllug chrisp (~wibble@host-92-26-195-66.as13285.net)
20:36.18toxboimorsing: It is 2.6.32-28-server #55-Ubuntu x86_64
20:37.43toxboiI suppose intr is supported until 2.6.25 but maybe Ubuntu backported it. I will looking into tomorrow.
20:38.28toxbois/looking into/look in to it
21:21.30ChoHagShould I abandon discs and go with SSDs throughout?
21:21.54ChoHagAt home, where I can afford to make my computer an extension of my  ego.
21:23.21wethrinIf you want fast access at a price, yes
21:23.34wethrinMy laptop's SSD, and it's made it usable
21:25.08ChoHagOh I know. I have an SSD in the laptop.
21:25.31ChoHagHad. I need to shuffle drives around.
21:25.51wethrinYou should make yourself an HFS
21:25.56ChoHagBut one disc in this machine has failed so I'm going to replace it along with the rest of the aging array.
21:26.22ChoHagThe so-called-nas is already scheduled for replacement ASATAF.
21:26.48wethrinAs Soon As something?
21:26.52ChoHagthere are funds
21:27.08wethrinAha
21:27.32ChoHagSpecifically, funds for playing.
21:27.53ChoHagAlso I kind of made myself complete my automation system before I bought it so that I could use it to build it.
21:28.03ChoHagAnd that's still not done.
21:28.06wethrinSo grab a handful of 2TB drives, RAID them up. Get a couple of SSDs, RAID-1 them together, stick them as an HFS front
21:28.18wethrinLet your filesystem contain awesomeness
21:28.24ChoHagRight, yes, which particular HFS are you referring to?
21:29.14ChoHagWhat does HFS mean?
21:29.52wethrinHierarchical File Store
21:30.10wethrinas oppose to the Mac's filesystem
21:30.45ChoHagYeah I didn't think you meant that.
21:30.55wethrinno, that'd be a bit pointless
21:31.03ChoHagThe only other thing google suggested was http file system, which didn't seem as profound as you seemed to be implying.
21:31.07ChoHagAlso seems icky.
21:31.29ChoHagAnyway I'm not doing that. I'm just fixing the desktop.
21:32.43ChoHagWhat sort of characteristics would a mixed disc/ssd array have>
21:33.02ChoHagThe naively hoped-for fast-read and slow-but-cached-write?
21:37.06wethrinAssuming read is appropriately cached
21:37.20wethrinIt depends how clever your HFS algorithms are
21:37.33wethrinWhether it copies data vaguely intelligently onto the fast disks in the background
21:38.15wethrinOkay, it looks like HSM is the more correct term
21:38.22wethrinHierarchical Storage Management
21:39.53wethrinhttp://ohsm.sourceforge.net/
21:39.54ChoHagWhere can you actually get decent hard drives these days?
21:40.54wethrinYou don't. You just get more of them.
21:40.59wethrinWell, define decent
21:41.06ChoHagHah!
21:41.44wethrinI think I've got some Hitachi Deskstars in my fileserver
21:41.49wethrinNot sure what I put into work's fileserver
21:41.55wethrinPossibly Seagates
21:42.50wethrinYes, Seagates
21:42.59wethrinThey are all currently working
21:45.34wethrinSo at home, I've got 5 drives in RAIDZ2
21:45.42wethrinAt work, it's a ZFS mirror
21:46.09ChoHagzfs will be on the not-a-nas.
21:46.33ChoHagThis will not I think. In this incarnation I tried out zfs for the bulk of the disc but it didn't work out well.
21:46.37ChoHagAlso pointless.
21:52.17wethrinZFS contains awesome
22:10.15ChoHagYes but this box doesn't have enough discs and I don't want/see the point in fucking about to get / on zfs.
22:10.29ChoHag(If it's built into the OS properly, fine)
