Guys - I am not sure what happened here but I think I have a problem with RAID (software) on my home machine. I am using it fine now however during boot up, I see something scroll by in red however it is un-readable at 100 mph so I decided to check out some md stats on the box to see if something happened to a disk or RAID array I setup and I can't understand what I am looking at so perhaps you guys can help.
To make things as clear as possible, I have 2 identical drives on the machine both via S-ATA. The drives are 2x Western Digital 160GB disks and I am pretty sure they are both good but I am not sure.
Here is what I see:
Code:
tunafish:/home/cwilliams/Desktop# mdadm --detail /dev/md0
/dev/md0:
Version : 00.90.03

As you can see there is a section that should match up below as /dev/sdb3 however it shows remove...
Then there is my 2nd RAID
Code:
tunafish:/home/cwilliams/Desktop# mdadm --detail /dev/md1
/dev/md1:

Is one of my disks bad? What should I do? Should I place an identical spare in place of /dev/sdb and see if it starts to rebuild?
Both drives feel warm to touch as they are both getting power and I visible in the BIOS so I know it sees the drives but perhaps it has failed sectors on the disk, I don't know...
Code:
tunafish:/home/cwilliams/Desktop# cat /proc/mdstat
Personalities : [raid1]
md1 : active raid1 sda4[0]
135275264 blocks [2/1] [U_]
md0 : active raid1 sda3[0]
19534976 blocks [2/1] [U_]
unused devices: <none>
Suggestions or comments from data above?
