kpartx verbose info: what does it mean?

Solution 1:

  • loop0p1: device mapper name
  • (252:2): major:minor of the device
  • 0: starting block of the map (I've never seen anything else than 0)
  • 131072: size of the device in blocks
  • /dev/loop0: parent device
  • 2048: starting block (block 0 of loop0p1 is block 2048 of loop0)
