Hi again,
I really need help on this - sorry to send another request for help.
Does anybody have a clue ? anything that can help me remount my vg without
dataloss if possible ?
Can anybody point me to documentation in saving a vg ? or a newsgroup on
usenet I can try ?

To say it another way - _any_ help would be appreciated !

Thanks in advance

/Klaus Pedersen
