[ubuntu] LVM2 add addtional disks

[somabc]

I have Ubuntu 9.04 beta on an LVM with the root filesystem /

 

I am trying to add a third disk to the LVM but I cannot see how you resize the filesystem. I have followed the steps on Resizing Ubuntu's root file system with LVM but the last step resizing the filesystem with

resize2fs -f /dev/ulvm/uvlm

gives an error (something to do with dev-mapper and the kernel)

 

The file system is 1.5TB but the Volume group is at 1.9TB (added 500GB drive to the volume group)

Please post the error message

It seems ok if I use the Ubuntu 9.04 LiveCD instead of knoppix, thanks
