hmm..luckily we have folder webapps in otehr location and change the permission own+group to zimbra and change it 775 permission... and ...and... its work...backup always be our saviour.
but still wonder what's gone wrong.. bcause some of admin features like HSM, licence mgt, mailbox quota mgt cannot revive even though with redeployed those admin zimlets..
my pain gone already and i can sleep tonight...
