Should it look for /dev/ploop51635p1 instead of /dev/ploop51635 ?

Further investigation show:

[root@node01 ~]# ploop-balloon discard -d /dev/ploop45088 --stat
Unable to find mount point for /dev/ploop45088
Usage: ploop-balloon discard {-d DEVICE | -m MOUNT_POINT | DiskDescriptor.xml}
{ [--automount] [--to-free SIZE] [--min-block MIN_SIZE]
[--defrag] | [--stat] }
DEVICE := ploop device, e.g. /dev/ploop0
MOUNT_POINT := path where fs living on ploop device mounted to
SIZE := NUMBER[KMGT] (maximum space to free)
MIN_SIZE := NUMBER[KMGT] (minimum size of a linear slice to be freed)
Action: discard unused blocks from the image.

[root@node01 ~]# ploop-balloon discard -d /dev/ploop45088 -m /vz/root/1712/var/log --stat
Balloon size: 0MB
Data size: 2716MB
Ploop size: 10240MB
Image size: 4242MB

I wonder how it looks for mount? I can't see any in /proc/mounts

Also what is the best way to check available space inside without logging in if I can't see mounts?

vzctl mount <veid>
seems mounting all drives including additional ploops and then ploops into container primary mount point. However there is no way see those mount till you start a container.

I can resize root filesystem, but not additional drives:
[root@node01 ~]# ploop resize -s 10G /vz/private/1712/root.hdd/DiskDescriptor.xml
dumpe2fs 1.42.9 (28-Dec-2013)
Changing balloon size old_size=5203034112 new_size=0
Successfully truncated balloon from 5203034112 to 0 bytes
[root@node01 ~]# ploop resize -s 10G /vz/private/1712/var.hdd/DiskDescriptor.xml
Error in ploop_mount_fs (ploop.c:1476): Can't stat balloon file /vz/private/1712/var.hdd/root.hds.mnt/.balloon-c3a5ae3d-ce7f -43c4-a1ea-c61e2b4504e8: No such file or directory
Error in ploop_mount_fs (ploop.c:1497): Can't mount file system (dev=/dev/ploop41532p1 target=/vz/private/1712/var.hdd/root.hds.mnt fstype=ext4 flags=0 data=): No such file or directory

I think I need to write bug report....
