As subject, I tried to change block device from qcow2 to raw format,
but it didn't make effect:
# lsblk /dev/sdc
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
sdc 8:32 1 14.6G 0 disk
# qemu-img info /dev/sdc
image: /dev/sdc
file format: qcow2
virtual size: 15G (15614803968 bytes)
disk size: 0
cluster_size: 65536
Format specific information:
compat: 1.1
lazy refcounts: false
refcount bits: 16
corrupt: false
# qemu-img create /dev/sdc -f raw 15614803968
Formatting '/dev/sdc', fmt=raw size=15614803968
# qemu-img info /dev/sdc
image: /dev/sdc
file format: qcow2
virtual size: 15G (15614803968 bytes)
disk size: 0
cluster_size: 65536
Format specific information:
compat: 1.1
lazy refcounts: false
refcount bits: 16
corrupt: false
As above, the format of block device was not changed.
Is it a bug or designed as this?
Thanks
