[10:41:13] <jhaluska> Hey T0mW , you around?
[10:41:18] <T0mW> jhaluska: bbl
[10:41:19] <jhaluska> k
[10:41:36] *** unrest has quit IRC
[11:11:26] <T0mW> jhaluska: I am back, and my Z2 dev computer has been repaired!
[11:11:27] *** g1powermac_PB has joined #zipit
[11:11:45] <T0mW> turns out that nothing was wrong with the hardware, the raid10 array would constantly resync on boot and that turned out to be a problem with udev.
[11:12:04] <T0mW> jhaluska: I now have enough parts to build another dev computer. All the stuff I bought trying to figure out what was wrong with this one. :(
[11:12:52] <jhaluska> Figure out what the problem was?
[11:13:26] <T0mW> yup
[11:13:31] <T0mW> ubuntu
[11:13:34] <jhaluska> The problem was the software?
[11:14:04] <T0mW> ubuntu distro came up with this new strategy of managing drives on a system. Redhat, Mandriva and Suse all followed suit at using udev to scan for drives and dynamically building out the /dev diretory entries.
[11:14:31] <T0mW> problem is that mdadm (md kernel driver) needs time to scan for drives to assemble a raid array. Having udev in the equation slows the array assembly down (postpones it) and the raid10 kernel driver is impatient.
[11:14:44] <jhaluska> Man, I don't think I would have figured that out.
[11:14:48] <T0mW> the raid10 driver runs before the md driver is finished finding all the drive components to an array. The result is that the you get an array that is incomplete
[11:14:51] <T0mW> resync
[11:21:09] <T0mW> I tackled it this weekend. After a lot of work, I could see that the problem was not in the kernel but appeared to be in the operating system files someplace.
[11:21:18] <T0mW> I joined the Linux-RAID mailing list and a fellow there knew exactly what was happening.
[11:21:29] <T0mW> so, "mdadm --grow --bitmap=internal /dev/md3" fixed it.
[11:21:50] <T0mW> adding a bitmap to a raid array mirror device (md3) tells the raid driver the status of the array and forces the raid10 driver to delay until complete assembly is done by the md driver.
[11:21:52] <jhaluska> Of course thats after the hardware purchases ruled out hardware
[11:21:53] <T0mW> pita
[11:22:03] <T0mW> jhaluska: I was a wee bit upset that what should have been an innocent update of my system software borked the raid5 array...
[11:22:19] <T0mW> It didn't trash it, but, I am very paranoid when an array undergoes a resync.
[11:22:24] <T0mW> ... on its own.
[11:22:37] <jhaluska> T0mW: Join #digitize
[11:22:50] <T0mW> jhaluska: it was a good thing though, got to retest (recertify) all the components in that computer. Also learned that I really wanted to be using raid10 instead of raid5 for my dev box.

[12:34:00] <steerpike> hey T0mW
[12:34:02] <T0mW> yo!
[12:34:05] <steerpike> i keep mixing up whether it was WEP that didn't work or WPA that didn't work
[12:34:24] <T0mW> heh, I haven't tried either. I'm just getting me dev box put back together after being out of service for 4 months.
[12:34:28] <steerpike> cool :)
[12:34:35] <T0mW> I'm anxious to get back to the Z2 stuff.
[12:34:38] <steerpike> ^_^
[12:34:54] <T0mW> Of course, I have a date wednesday night with a woman for coffee, so, that may change my plans a bit?
[12:38:20] <steerpike> oh, that doesn't sound good for us :S
[12:38:24] <T0mW> heh
[12:39:00] <jhaluska> steerpike: WEP
[12:39:22] <steerpike> jhaluska: so you got it to work with WPA/2?
[12:39:27] <jhaluska> steerpike: Nope, but I haven't tried either.
[12:39:35] <steerpike> how long has it been since you last tried it?
[12:43:34] <jhaluska> WEP?
[12:44:13] <steerpike> on zipit
[12:44:19] <jhaluska> hmm months ago?
[12:48:50] <steerpike> you've done nothing since?
[12:48:53] <jhaluska> Pretty much
[12:48:53] <steerpike> lol
[12:49:00] <jhaluska> I haven't finished rebuilding my laptop.. been busy and lazy

[16:12:06] <switchcat> I just ordered a new laptop
[16:12:21] <jhaluska> What kind?
[16:13:04] <switchcat> uhm compaq
[16:13:05] <switchcat> $278 + tax
[16:13:11] <jhaluska> Thats not bad
[16:13:30] <switchcat> yeah there was a live.com 40% off of hp.com cashback deal.
[16:13:37] <switchcat> so I'm getting $185 or so back from M$/live.com
[16:24:31] <jhaluska> Thats pretty nice

[16:34:59] <steerpike> switchcat: is the sale still available?
[16:43:20] <switchcat> steerpike - nope, black friday only
[16:43:23] <steerpike> oh well.. mail-in rebates suck anyway
[16:43:25] <switchcat> it was really difficult to get into, too... the website is overwhelmed
[16:43:27] <switchcat> and it's not a mail-in rebate
[16:43:28] <steerpike> oh
[16:43:30] <switchcat> it's a live.com cashback deal it's all online
[16:43:30] <steerpike> i see
[16:43:40] <switchcat> you search for the store via live.com search click on the appropriate link, go to the site and buy through that
[16:43:46] <steerpike> cool
[16:44:02] <switchcat> they have all sorts of deals.. like stuff like 25% off ebay purchases (to a maximum of $200, I think)..
[16:44:06] <switchcat> and you can earn up to $2500 a year in live.com cashback I think
[16:44:24] <steerpike> wow
[16:44:29] <steerpike> so it's not just black friday?
[16:44:39] <steerpike> i guess they'll do anything to get people to use their search engine lol
[16:50:45] <switchcat> yeah only the 40% off HP.com purchases was black friday (normally it's 5%)
[16:50:45] <switchcat> each store/website is different in the amounts
[16:50:45] <steerpike> nice
[16:50:49] <switchcat> speaking of which I should really go to lowes and go get some gift cards so I can get 20-30% on my money
[17:12:31] <jhaluska> You can do that?
[17:12:38] <jhaluska> I spend a lot at Lowes
[17:14:13] <g1powermac_PB> mmm, Lowes or Home Depot, or any tool store?
[17:14:26] * g1powermac_PB got a whole welding rig just recently
[17:14:38] <jhaluska> g1powermac_PB: Do you live in NJ?
[17:14:55] <g1powermac_PB> no, but I did for most of my life
[17:20:56] <g1powermac_PB> I left NJ about 5 years ago
[17:22:38] <jhaluska> gtg, catch you guys later.
[17:22:54] *** jhaluska has quit IRC
[17:24:23] <steerpike> hrm.. tigerdirect has a live.com 15% off computer sale
[17:24:30] <steerpike> too bad they suck
[17:31:02] <switchcat> g1powermac_PB - currently Lowes has a 4-day sale ending today. For each $100 worth of gift cards you buy, you can get an additional $20 in gift cards with a mail in rebate. (Thats like getting 20% on your money) in addition to that apparently there was some sort of $10 off coupon that was appearing on each of the register receipts.. so it's more like 30% on your money. And Lowes gift cards have no fees and no expiration dat
[17:31:26] <switchcat> btw, you can get up to $300 in gift cards for this, so you can get $60 back (so, if you get 3 different gift cards, you can ring each up separately for an addition $10 off coupon on each receipt.. making it +30$)
[18:24:43] <g1powermac_PB> hmm, nice
