Hello,
while using qemu 2.9.1 and doing a backup of a disk:
I have sometimes the following output:
Formatting '/mnt/qemu-249-2017_11_19-04_00_05.qcow2', fmt=qcow2
size=236223201280 encryption=off cluster_size=65536 lazy_refcounts=off
refcount_bits=16
followed by:
kvm: Failed to flush the L2 table cache: Input/output error
kvm: Failed to flush the refcount block cache: Input/output error
If this error happens (Failed to flush) the whole backup is incomplete.
Host kernel is a 4.4 based openSuSE 42.3 kernel.
Is this a known bug?
Greets,
Stefan
