Hello to all, from few days ago i have encountered a problem with one of mine kvm machine, i cant start the machine beacause the disk-1.qcow2 is corrupt.

If i run qemu-img check -r, all the free ram of the node (40 GB) will be consumed in just 3 seconds and affect all the virtual machine from the node.

The output of qm start 108:

Code: 
kvm: -drive file=/var/lib/vz/images/108/vm-108-disk-1.qcow2,if=none,id=drive-sata0,format=qcow2,aio=native,cache=none,detect-zeroes=on: could not open disk image /var/lib/vz/images/108/vm-108-disk-1.qcow2: qcow2: Image is corrupt; cannot be opened read/write

#free -m ?

#ps -aux|grep qemu-img ?


Do you have tried to use "qemu-img check -r leaks" ? It's only scanning metadatas

free -m output
Code: 
             total       used       free     shared    buffers     cached
Mem:         64413      25847      38566          0         62       1701

Swap:        10239       8746       1493
Correct command it is: ps aux | grep qemu-img vm-108-disk-1.qcow2
Output:
Code: 
Nothing to output

qemu-img check -r leaks
The same problem , after i run this check, ram memory it's growing up from 25 GB used, to 60 GB used in just 10-15 seconds.
