Is there a way to mount a dd based file as a disk for cstore pool
You havent created a partition table on the virtual disk.
Do the DD as above, then run the output of that through gparted or fdisk and creat a partition table
then do an losteup losetup -f diskImage4
then read the partitions partx -a /dev/loop0
(or whatever the loop device is created as
Then do a lsblk
loop0 and loop0p1 should be visible
