Stop the container/ check container status where ploop problem exists [if you working with "backup" something like root.hdd ploop file with DiskDescriptor.xml you should not stop any containers]
Mount the container’s ploop image. Check fdisk:
cd /vz/private/CTID fdisk -l root.hdd/root.hdd
Mount:
ploop mount root.hdd/DiskDescriptor.xml Opening delta /vz/private/16311/root.hdd/root.hdd Adding delta dev=/dev/ploop28980 img=/vz/private/16311/root.hdd/root.hdd (rw) #note the dev=/dev/ploop2890
As from previous output we can see how it's mounted dev=/dev/ploop2890 Try e2fsck
e2fsck /dev/ploop28980
If fail try with another superblock:
mke2fs /dev/ploop28980 # note the block here and use one of them e2fsck -b 32768 /dev/ploop28980
Maybe mount/remount and give a check w/o specifying superblock
e2fsck /dev/ploop28980
___________________
if still issues you may try to mount ploop into folder and copy data
Unmount first of mounted
ploop umount -d /dev/ploop1234
Mount into some dir
mkdir /mnt/ploop-restore1 mount -r -o noload /dev/ploop30196 /mnt/ploop-restore1

This link may be helpfull if you do not have ploop kernel support (we did not tested it!):
