Today Adan celebrated his 9th birthday. We hung out this morning building his new Clone Wars LEGO set, then had Sonic for lunch. In the late afternoon we had a chance to go roller skating (my first time on roller skates), then had dinner @ Carrabbas. It was definitely a good day (at least for me)

Fedora 13 *installed*
I finally got Fedora 13 installed after having some issues with my software RAID partition last night.
I have 3 250GB drives. Two of them were software raided in RAID 1 configuration holding /home. The third is where the OS lives. I ignored the error message anaconda presented me since I could still use /dev/sda which is where I wanted to install anyway.
I choose to Fresh Install from the menu, then Basic Storage Devices. I proceeded to choose the only hard drive that showed up, and said I’d create my own custom partition layout. This part probably wasn’t necessary but I wanted to make sure the partitions that existed were the ones on /dev/sda
Once the installation was done, I switched to runlevel 3 and logged in as root. This is what I did to recover my software RAID partitions to mount them as /home.
# mdadm --assemble --scan
# cat /prod/mdstat
Personalities : [raid1]
md0 : active raid1 sdc1[1] sdb1[0]
244195904 blocks [2/2] [UU]
unused devices:
# mdadm --examine --scan >> /etc/mdadm.conf
# tail -n 1 /etc/mdadm.conf
ARRAY /dev/md0 UUID=93ea08fa:1a7ae881:f59ceb98:8b2b169f
So far so good. But df -h didn’t show my LVM partition from the RAID device.
lvscan showed it as inactive:
# lvscan ACTIVE '/dev/vg0/lvswap' [3.00 GiB] inherit ACTIVE '/dev/vg0/lvroot' [214.69 GiB] inherit inactive '/dev/vg1/lvhome' [232.88 GiB] inherit
Ok simple need to change that.
# vgchange -ay 2 logical volume(s) in volume group "vg0" now active 1 logical volume(s) in volume group "vg1" now active # lvscan ACTIVE '/dev/vg0/lvswap' [3.00 GiB] inherit ACTIVE '/dev/vg0/lvroot' [214.69 GiB] inherit ACTIVE '/dev/vg1/lvhome' [232.88 GiB] inherit # ls /dev/mapper/ control vg0-lvroot vg0-lvswap vg1-lvhome
Last thing to do is get /etc/fstab updated:
/dev/mapper/vg1-lvhome /home ext4 defaults 1 1
And for good measure, blow away the old user home dir from the install, and mount
the homedir:
# rm -rf /home/jmrodri
# mount /home
# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/vg0-lvroot
212G 5.8G 195G 3% /
tmpfs 1005M 0 1005M 0% /dev/shm
/dev/sda2 190M 50M 131M 28% /boot
/dev/mapper/vg1-lvhome
230G 91G 128G 42% /home
Sweet back in business. Let’s reboot and make sure everything’s good.
Everything was good upon reboot except when logging in as jmrodri it couldn’t find my homedir. I checked the permissions and they were fine. What could it be? ponder. run series of commands. google. ponder some more. google. SELinux! The new /home had the wrong SELinux context.
# restorecon -R /home
There now we’re good.
Fedora 13 install a no go
Tonight I tried to install Fedora 13 over my old Fedora 11. The plan was to use /dev/sda1 as / and keep /home on my software raid RAID1 partition (/dev/sdb1 and /dev/sdc1). But during the install I got an error message:
Warning Disks sdb, sdc contain BIOS RAID metadata, but are not part of any recognized BIOS RAID sets. Ignorning disks sdb, sdc.
So I went through all of the CTRL-ALT-F{1-6} to gather information.
CTRL-ALT-F1

Anyone have any thoughts? This setup works fine in Fedora 11. How can I get past this error so I can mount /home on my software raid partitions.
Panovit is dead
In an attempt to get Pandora on my TiVo I started a project called panovit. With limited time I wasn’t able to get very far with it, but I did learn some cool things about gstreamer and the TiVo HME SDK. Today TiVo released Pandora for TiVo so I can now retire panovit.
