[Linux-HA] haresources/Filesystem - mounting file via loopback

[Lukas Lisa]

hi;
i would like to mount a file via loopback but I can't to find right 
syntax for haresources.

i tried

node1 147.231.4.133 
Filesystem::/mnt/mail/ext3acl.img::/mnt/samba/::ext3::loop=/dev/loop0,acl

but it doesn't works because Filesystem:: expects regular device as 
first argument.

probably i will need some script to set loopX and then to use Filesystem::

can anyone help me to write this script or solve this problem another way?
thanks a lot
Lukas
