assumed that you ahve set up quota hashes properly,
assigned a quota hash to the vserver context and
activated quota with the quota tools (not required
for per context disk limits) then thequota hashes
write to the quota files on the partition (in the
vserver root path), and are read by the quota system
on quota start ...

disk limits do not use the quota hashes themselves
but they make use of the structures and require
them to be assigned ... saving the 'current' value
on vserver stop and restoring it on vserver start
should be sufficient ...

disk space is 'gained' for files/inodes belonging
to the context (xid of the files) freeing them, you
will not gain space for files in the host context
when they are removed from within a vserver ...

(use lsxid/chxid to manage the xids)
