Intel Wireless pains on a Sony VAIO (mirrorlist snafu part 2)

Posted by jamba on February 15, 2010

As I mentioned in the last post, I re-installed Arch onto my laptop.  This went very well, and quickly–everything really fell into place.  I was going by the beginner’s guide, as detailed previously, but it was not really needed this time.

Where I left off last time, Xorg was installed and I was about to install Gnome.  That went well enough, although I had to re-rank my mirrors and put the most updated first as there was some kind of discrepancy with some that had not been sync’ed in a few days.

I then started having problems with…wireless, of all things.   It would work manually:

ifconfig wlan0 up
iwconfig wlan0 essid x key xxxx 
dhcpcd wlan0

On boot, however it would not work.  Oddly enough, I had done all of the updating and everything to this point on a wired connection…all of a sudden, the wired connection won’t work, either.

Linux RAID disk wipeout:

A common problem with Linux software RAID (aka md) happens when you try to use a disk that was previously part of some other disk array. Symptoms include: wrong volume size, unable to add device to raid, volume UUID mismatch. To fix the problem you need to use mdadm utility on the disk to cleanup:

# mdadm --zero-superblock devicepath

  -Similar to the articles I have referenced before, when I wrote a series of posts about setting up my software RAID1 wich my Arch setup.
