URGENT, SERVER DOWN! I tried partitioning the second drive and formatting to use as backup, and at some point, it requested reboot to load to kernel the new partition tables... after reboot, the server didn't came up again. also, while trying to partition and format the second drive, it was going extremely slow (I worked 4 hours on it...) and errors poped out... I come to the conclusion, that the second drive of 500GB is useless and damaged, and your failure on past, was because of corrupt hardware, thus, you need to take these steps to proceed: ticket to FDC to: -remove ASAP /DEV/SDB (second, 500 GB sata drive) -edit in safe mode /etc/fstab and comment out with # the last line that is mounting of backup partition... -boot the system and make sure all are ok, and perform for safety a complete scan disk (fs check)... -shutdown the box and install a new replacement secondary drive of 500GB -boot the system, and at this point email me again to format and mount the new drive...
