Life + Geek, intermixed [Jul. 21st, 2003|01:47 am]
Brad Fitzpatrick

Left Seattle Friday afternoon.

Do not buy Adaptec RAID controllers!! (aacraid) Biggest pieces of shit ever. We bought 5 servers with them and they're failing one after the next. We replaced a few after they ate themselves, but now we're proactively replacing them, switching to Intel's RAID controller (gdth). Too bad Mylex (dac960) doesn't still exist... *sigh*

Spent the weekend with Dina, doing misc fun stuff. Also hung out with Nick. Saw the movie "Swimming Pool".

Went on a bike ride today with Whitaker.

Mail::Audit is cool, but MIME::Entity's as_string method (on which Mail::Audit is built) seems to eat a shitload of headers. Not good. Need to investigate more before I can switch away from procmail.

So behind.

My home computers suck. I'm always buying servers (for LJ) but my home computers have been neglected. I'm not sure about the whole root NFS thing anymore. I love the silence of not having disks, but if I do it again, I'll definitely need gigabit. I'm getting weird NFS timeout errors lately and my desktop locks up for a second or two. I hate NFS. Maybe I'll do boot/root filesystem on compact flash, enough to setup a network block device connection (over gigabit) and mount normal filesystems over the nbd in the distant closet (where I can't hear the disks). I don't need the filesystem accessible by multiple clients at once, so I lose nothing by doing nbd instead of NFS.

Getting excited about new Linux 2.6 features. Both desktop and server stuff look very fun.

RAID and root NFS

I'm a bit concerned that you're having problems with the Adaptec RAID cards -- I've got various clients with various Adaptec RAID cards. Fortunately most of them seem to be DPT_I2O style cards (ie, SmartRaid V) which so far I've found to be okay. What are you seeing as problems with your RAID cards?

A random thought with regard to NFS root (which I used for a few years prior to buying a very quiet running laptop and using that instead): given the cost of RAM these days, and the relatively small amount of stuff required for a basic workstation (eg, 200MB of stuff for a basic workstation, and that much RAM costs hardly anything), it occurs to me that it might be practical to just netboot an image that creates a large ram disk, sucks everything across into the ram disk, and then runs from ram. With, say, 1GB of RAM in the workstation (say 1/3rd to 1/2 for the ram disk), and most things done on remote machines, it might work pretty well.

Compact flash boot works well for things which can't be netbooted but you really want to boot into a ramdisk and run just from ram to avoid wear on the compact flash. (The claimed 1,000,000 write cycles might seem like a lot, but if some areas get several thousand writes a day, it won't last that long, especially if they're off by, eg, a factor of two in their estimates.)

RAID and root NFS

so far its been both the 2120s and 2200s, using the aacraid driver.

nothing really

I have to say that it amuses me that I do an interest search for "fire" and you popped up in there.

Meh, randomness... I sleep now and leave to baffled (or myself baffled...can't tell which).

I loved the DAC960 Mylex controllers. Never had a problem with them. Bought a few off of Ebay a few months ago. Had good luck with the Acceleraid versions too.

Intel raid is good. I've been using them on all my servers and they are rock solid. Only have some minor problem when running them on windows 2003 (I solve it after 2-3 hours, but I doubt you will be using any win2k3) but other than that, it's a good piece of hardware.

Aww buttfuck.

All my machines have dpt_i2o cards.. I sure do hope we're not talking about the same ones here.. I wouldnt even know how to change them, since it appears to be onboard. I guess shove a PCI card in there and let it rip?

The blonde chick in "Swimming Pool" is hot, likes being naked and does it with who ever is around. I would just always be around. She is my type of woman. Only thing she seems not to take rejection well.

swimming pool!!

Was that a good movie? I have been contemplating seeing it but the review said its a "psychological-sexual thriller" which for me is not a July-type movie
