[Qemu-discuss] deleted inodes in qemu-nbd snapshot |

Hi,
I'm taking snapshots of a disk image with qemu-nbd, but I regularly have files with deleted inodes in the snapshot. Here's what I do exactly:
virsh shutdown $domain
while virsh list | grep $domain > /dev/null; do
sleep 2
done
echo 'Domain stopped'
# Sleep to see if it avoids deleted inodes in the snapshot
sleep 5
disk_file=$(virsh domblklist $domain | grep vda | awk '{print $2}')
echo disk file = $disk_file
qemu-nbd --snapshot --read-only --connect /dev/nbd${nbd_num} --nocache $disk_file
# Sleep to see if it avoids deleted inodes in the snapshot
sleep 5
# Now that we have the snapshot, start the kvm
virsh start $domain
Can it somehow be due to changes done on the disk by the running domain? (the error often happens with pid files)
In the hope someone can help me further debug this
Thanks
Raph
