[vserver] cannot find vserver-setup

i have a running vserver that works perfectly but today i cannot enter it. i can enter
others but not this one meaning i also cannot shut it down manually. i get the following
error:

enterprise vservers # vserver cacti enter
Can not find a vserver-setup at '/etc/vservers/cacti/'.

Possible solutions:
* fix the spelling of the 'cacti' vserver name
* read 'vserver cacti build --help' about ways to create a new vserver
* see 'vserver --help' for the syntax of this command

i compared the contents of that dir with others and it looks the same.

any clues where to look?

there was a host crash that was hardware related but it is back up and everything works. i
had to rename some dirs in a vserver and copy their contents into the new dir because i
kept getting an apache message 'not a valid directory' however that is fixed. i thought
this problem may be similar but renaming and copying contents did not help.
