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
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)


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?
