qm start 100 gives: qcow2: Image is corrupt; cannot be opened read/write

kvm: -drive file=/var/lib/vz/images/100/vm-100-disk-1.qcow2,if=none,id=drive-scsi0,format=qcow2,cache=none,aio=native,detect-zeroes=on: qcow2: Image is corrupt; cannot be opened read/write

One of the follwoing can be the reason:

- Error inside qcow2 file - check it by "qemu-img" (see respective man-page for further information as well as https://lists.gnu.org/archive/html/qemu-discuss/2014-10/msg00023.html)

- Error in filesystem where qcow2 file is stored (repair filesystem first by fsck.ext4 etc.)

is there any way to fix this ?

Depends on the damage, try the above! But there is no guarantee for success-
