Then I said to myself (I will mount the drive and delete files on it then add it back to see how well the regeneration works. After I deleted most of the files on the disk, I did a "umount /mountpartition" (without the quotes) and the server locked up. I hard booted the server and it came back to a grub prompt. Can you tell me why and possible how to fix it? mB.
