Hello.

I have a problem with one of ploop images. Ploop can't work with an image:
# ploop mount /vz/private/5948/root.hdd/root.hds
Opening delta /vz/private/5948/root.hdd/root.hds
Error in range_build_rmap (balloon_util.c:542): Image corrupted: L2[28555] == 311619 (max=629143552) (2)
Error in check_deltas (check.c:715): /vz/private/5948/root.hdd/root.hds : irrecoverable errors (rw)


On OS Installed a ploop version
# cat /etc/redhat-release
Virtuozzo Linux release 7.7
# rpm -qa | grep -i ploop
ploop-7.0.163-1.vz7.x86_64
ploop-lib-7.0.163-1.vz7.x86_64
python-ploop-7.0.163-1.vz7.x86_64


I replaced baseurl in openvz-os repo
baseurl=http://download.openvz.org/virtuozzo/releases/openvz-7.0.11-235/x86_64/os/

and downgraded ploop and all dependesnses versions to previous release
# yum downgrade libvzctl libvcmmd python-ploop libvzctl ploop-lib ploop

When I did it, ploop mount the image correctly
# ploop mount /vz/private/5948/root.hdd/root.hds
Opening delta /vz/private/5948/root.hdd/root.hds
Opening delta /vz/private/5948/root.hdd/root.hds
Adding delta dev=/dev/ploop36860 img=/vz/private/5948/root.hdd/root.hds (rw)


I checked the image on downgraded ploop version
ploop check --force --repair-sparse /vz/private/5948/root.hdd/root.hds
ploop mount /vz/private/5948/root.hdd/root.hdd
fsck.ext4 -f -y /dev/ploop36860p1
ploop umount /vz/private/5948/root.hdd/root.hdd


These commands reports that image is ok.
When I upgrade downgraded utils to latest version, ploop returns the same mistake again.
# ploop mount /vz/private/5948/root.hdd/root.hds
Opening delta /vz/private/5948/root.hdd/root.hds

Do you know how to fix this mistake with ploop image?
Did somebody get the same mistake after upgrade ploop utils from 7.0.157-1.vz7 to ploop-7.0.163-1?

I did resize image on downgraded ploop version.
ploop resize -s NEWG /vz/private/5948/root.hdd/DiskDescriptor.xml

And latest ploop version works with the image correctly when I did it.

I interesting in is there a way to fix the error without reverting to the previous ploop version.

We encountered the same/similar problem.

We have a container running for long time, and in good status (we use snapshot to backup it content. i.e. vzctl snapshot, snapshot-mount, rsync, snapshot-umount, snapshot-delete)

Now, we need to clone it to another server for better resource.
We stop the container 3xx3.
scp those /vz/private/3xx3 content to another node.
In another node,
cd /vz/private/3xx3
ln -s 5 .ve.layout
prlctl register --preserve-uuid /vz/private/3xx3

Then, it successfully registered the container.

Then, we start it (as usual, OK to start successfully)

Then, in midnight, we run vzctl container snapshot backup as usual.
However, it failed to mount the snapshot
