Today we had our DC replace a failing harddrive in our RAID array, this is the first time I have ever had to do this. However I am now trying to resync the array and I am having difficulties understanding how this systems even working right now.
Our current working drives partition table is the following:
Disk /dev/sda: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x56565656 Device Boot Start End Blocks Id System /dev/sda1 1 2089 16777216 fd Linux raid autodetect /dev/sda2 * 2089 121602 959983616 fd Linux raid autodetect
How come the end cylinder of /dev/sda1 and the start cylinder of /dev/sda2 are the same? Because of this I am unable to replicate the partition table on the new drive.
