sudo fdisk -l
Disk /dev/vda: 42.9 GB, 42949672960 bytes, 83886080 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x635e6c7d
Device Boot Start End Blocks Id System
/dev/vda1 2048 83886079 41942016 83 Linux
Disk /dev/vdb: 107.4 GB, 107374182400 bytes, 209715200 sectors
