reiserfs woes with 2.6 kernel. move to reiser4?
so i've been trying to get this storage server up and running so i can decommission the old kind of scary setup we have now and use it for something not so mission critical. after starting over at least 6 times with a new LVM configuration and mkfs i've still been running into wacky kernel panics at random times and haven't been able to mirror the whole 2.7 terabytes of data yet. as of recent, my filesystem seems to have corrupted itself to the point where i cannot mount it in read/write for very long. while trying to continue my mirror operation, i noticed "read only file system" errors from rsync. when i checked /var/log/messages i saw these:


Jun 23 12:56:20 gpclstorage kernel: REISERFS (device dm-3): Remounting filesystem read-only
Jun 23 13:36:07 gpclstorage kernel: REISERFS (device dm-3): Remounting filesystem read-only


some more research indicated that i may have created too large a filesystem for reiser3 to handle but some people were working with 20+ terabyte volumes with no problem, it seemed. the fact that it works fine for a while and then breaks horrendously is not reassuring.nerd stuff )

centos 5.3 and the dell PowerVault MD3000 storage unit
to get this working correctly i had to:

- install DELL's storage management software from the PowerVault MD3000 Resource CD.

- configure/initialize a volume using the storage manager

- install the linux tools by running install.sh in the /linux folder on the resource CD.

- make sure that multipathd is running in the current runlevel

- edit multipath.conf adding these lines at the end:


devices {
device {
vendor DELL*
product MD3000*
path_grouping_policy failover
getuid_callout "/sbin/scsi_id -g -u -s /block/%n"
features "1 queue_if_no_path"
# path_checker readsector0
path_checker rdac
prio_callout "/sbin/mpath_prio_tpc /dev/%n"
hardware_handler "1 rdac"
failback immediate
}
}
# now blacklist the 20M recovery partition or whatever-the-heck-it-is.
blacklist {
device {
vendor DELL.*
product Universal.*
}
device {
vendor Dell.*
product Virtual.*
}
#devnode "^sd[a-b]"
}


- edit /etc/lvm/lvm.conf modifying this section:


# By default we accept every block device:
#filter = [ "a/.*/" ]
filter = [ "r|/dev/sde|" ]


i commented out the filter = [ "a/.*/" ] line and added the next filter line.
this hides the 20M sde partition from lvm's pvscan. this may or may not be the same for your install.

- i next had to configure LVM (after rebooting and making sure everything was ok, i'm sure)


# pvcreate /dev/dm-2
# vgcreate storage /dev/dm-2
# lvcreate -l 3098406 storage


i was then able to install reiser4 and mkfs.reiser4 on that partition.

XFS might be a better option for those who do not want to deal with kernel patching and recompilation.

after 2.6.30 kernel rebuild "cannot access the hardware clock"
what ended up being the problem was that i was updating from a 2.6.18 kernel which was using /dev/rtc for the real time clock device. 2.6.30 is using /dev/rtc0

i fixed this problem with:

mv /dev/rtc /dev/rtc-backup ; ln -s /dev/rtc0 /dev/rtc

making a symlink to the real device allows the hwclock command to access the clock now.

shredded hub? iron city bikes commercial.
on my way to work friday, i did a pedal kick and pulled the front wheel up a little bit to hear a big *KER-CHUNK* noise and then instantly a new, less happy sounding clicking noise that wasn't there before began to come out of my hub.

i dropped the wheel off at the shop today. hopefully after work i'll get to watch bob open up the hub and check it out. i sure hope it's something easy, but i'm not betting on it.

i totally came up with an idea for a commercial idea for iron city bikes a while ago. it involves me and bob as "jay and silent bob" and a boombox in front of the shop. of course bob will be silent and have a trenchcoat and cigarette and i will be dancing around like a dufus and interacting with passersby. i just have to convince jeffG or someone else with a decent camera to tape the footage i'd need.

(i'll have to make an "I ASSURE YOU, WE'RE OPEN" sign for the door)

my thoughts on ubuntu
what a pile of crap. what was wrong with debian that this garbage even exists for?

so... the 8.10 installer? junk. i tried the regular cd, the alternate-install, and, finally, a netboot install. the netboot install failed several times, but i think i figured out the problem by hitting alt-f4 to see that dhclient was unable to write the lease file. alt-f2 to open a new console and creating "/var/state" and "/var/state/dhcp" and then running dhclient seemed to speed things up. this is of course a bug that i won't be signing up for yet another discussion board (YADB) and reporting. i could care less if ubuntu dies in the water. i just want to get this application running so i can modify it.

i really despise it when people develop useful projects on such shitty platforms. ubuntu is not a good development environment! try using something based off of RHEL (centos, fedora, redhat). try using an OS that isn't developed for clueless noobs to throw on laptops. when the user base of an open source project (os, application, whatever...) is clueless noobs, not many useful contributions from the user base are going to come in besides useless fancy graphics and desktop skins that use more memory than most older laptops can even handle. hell, the *installer* has a 256M minimum memory requirement. i have installed netbsd on machines with 32M of ram. the minimum requirement for netbsd-i386 is 4MB. now there's a REAL os.

it shouldn't take a person with a decade of linux experience 2 weeks to get an OS running after trying the typical methods.

end rant.

centos 4.4 -> centos 5.2 yum update [DON'T DO IT!] (ala: Kurtis Blow)
by some small non-miracle, i was able to get a centos 4.4 box to update to 5.2 using yum and the instructions here.

i had to uninstall a few extra packages using the --dbonly flag, but eventually all of the dependencies were satisfied.

i only had two problems after the update. i am now down to one.

the first problem i noticed is that my fvwm window manager no longer had any text or colors other than black. a google search seemed to point at the rgb.txt file not being found, which is totally what was happening. i edited xorg.conf to set RgbPath to the correct location and all is well with my window manager, which is good, because i can only stand using fvwm. every other window manager either has a thousand limitations that prevent me from finding it user-friendly, even with modifications... OR it is so minimal that there are no options for modifying it.

now my only problem is that dns is not working. my home network's dhcp server should be sending the DNS server config to this client, but it's not getting set. i'm about to investigate that more closely.

Dirty Dozen
i entered danny chew's dirty dozen bike race last saturday just to get a feel for it, and despite having to bow out after 4 hills due to my cold and managing to reverse my healing process for a couple days, i had fun.

i rode in the car with [info]smkurp, lomax, and sarah to a few of the hills to watch the riders until 10th street in the southside, where i bailed out and biked home (after a short stop to see bob @ iron city bikes).

my plan for next year is to put pursuit bars on my trek 7200 with sti shifter/brake levers and a set of "problem solvers" so that the brake levers work with my v-brakes. i'll also need a new rear derailleur before then. mine was shot and was causing some problems when trying to shift while going up huge hills.

i ran a setup with "old school" friction shifters on the ends of my bar ends which worked pretty well, considering my wobbly derailleur.

i'll be ready for next year. I finally kinda know the route. <- Google Earth File.

kenwood amplifier: F!><()R3D
sometime this past summer, my stereo power amplifier got drenched with water while powered on, which fried one of the channels and blew a fuse. some pics in this post.

i tracked down the user manual and a source for matched transistors and had the things laying around for months next to the 'exploded view amplifier' on the sweet trashpicked ikea coffee table in my living room.

tonight, after some initial sleuthing to determine what-went-where (gotta love walking away from something disassembled for months at a time) i got the transistors mounted onto the heatsinks with hopefully enough thermal grease to keep things from melting down, and all of the screws back in where they went.

i'm currently listening to the tv through the amp and it seems to be working fine. i didn't bother to check the bias current setting for the channel i replaced, figuring that if the transistors were matched it shouldn't need adjusted.

i had originally thought i would replace both channels, but i'm going to defer to the "if it ain't broke" rule.

it's amazing how much more clarity this amp has than the trashpicked jvc amp i was using. i think might be the extra-fast switching on the sanken 2sa1216/2sc2922 combo.

since some people gotta be doubters and i was bored...
some people have been disputing my youtube video of me going 39.6mph in 40x16 gearing on a fixed gear. i don't like to make false claims, and when someone calls me on it, i am a humble enough person to doubt myself.

i was bored, so i thought i'd double check the facts.

ancestry... hmmm.... am i descended from a "terrist?"
the other night i was up late and put some serious effort into digging into my lineage a bit. i traced my late grandfather's (and mother's) lineage back to the ancestor who came here from scotland.

i'm probably not the only native pennsylvanian in the same boat, due to our state being the floor underneath the "melting pot" that is NYC (and boston, to a degree only for the UK).

it turns out that he and his brother were on the losing side of the revolutionary war.

it's a longish story )
