centos 6 failed to create entries under /dev for newly created loopback devices. Any one know why? and how to fix/workaround it? The steps to duplicate is pretty simple dd if=/dev/zero of=/tmp/deleteme bs=1M count=100 losetup /dev/loop0 /tmp/deleteme fdisk /dev/loop0 ## created partitions 1, 2, etc. fdisk -l /dev/loop0 ## confirmed that the partitions do exist mkfs.ext3 /dev/loop0p1 ## failed here, the error prompt says that the /dev/loop0p1 doesn't exist! ls /dev/loop0p* ## no entries Please shed a light here, I'm running centos 6.4 Thanks.
