i had 2 partitions with following layout
Disk /dev/xvda: 376.4 GB, 376354897920 bytes 255 heads, 63 sectors/track, 45755 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: 0x000da515 Device Boot Start End Blocks Id System /dev/xvda1 * 1 64 512000 83 Linux Partition 1 does not end on cylinder boundary. /dev/xvda2 64 2613 20468736 8e Linux LVM /dev/xvda3 2613 7835 41948160 8e Linux LVM
I accidentally gave 350GB of space to this disk, but i wanted it to be 100GB, now i can make another 100GB volume from SAN, and want its data to be moved to that disk with 100GB size.
I have already tried to use gparted, parted, but none worked for me. even DD is not working in this scenario. may be clonezille would be helpful?
