The SAN controller is a DS4700 formerly known as FASTt. We have a LUN with 200 GB of size. The LUN ist partioned: fdisk -l /dev/sda Disk /dev/sda: 214.7 GB, 214748364800 bytes 255 heads, 63 sectors/track, 26108 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 125 1004031 83 Linux /dev/sda2 126 26108 208708447+ 5 Extended /dev/sda5 126 188 506016 83 Linux /dev/sda6 189 1185 8008371 83 Linux /dev/sda7 1186 1435 2008093+ 83 Linux /dev/sda8 1436 1560 1004031 83 Linux /dev/sda9 1561 1810 2008093+ 83 Linux /dev/sda10 1811 2060 2008093+ 83 Linux /dev/sda11 2061 4053 16008741 83 Linux /dev/sda12 4054 24960 167935446 8e Linux LVM /dev/sda13 24961 26108 9221278+ 82 Linux swap Now i had to increase the size of partition of sda12 which is a LVM. I am not sure which is the right way. Within the storage managment software i can increase the size of the LUN. After rebooting the machine the additional space is appended at the end of partitions and it is marked as free. How can i now increase the LVM partition. Which tool/programm i do need for this task?
