Description Roman Shtylman 2009-07-21 00:03:30 UTC
When trying to boot into any 2.6.31+ kernel my system hangs with the error:

"device-mapper: table: 252:0: sda too small for target"

The above error just keeps getting echoed out to the screen. This did not happen prior to the .31 kernel(s).

/ is on two disks in raid 0. Each disk is 32GB making a total of 64GB for root. There is 37GB of free space on root so free space is not the issue. 

I use dmraid for my multidisk setup, and up until this kernel line, have never experience such an error in booting.
