I have lost my /opt (ie I can not fsck it) because it is encapsulated into volume manager. And volume manager is sitting in the /opt, which means that volume manager is unavailable because, it's sitting in a filesystem which needs, to be fixed... And it can not be fixed becuase VM is not running... It's a vicious circle. Please help, I have a full day downtime!! I tried logging in in single user mode (using cdrom), but still I can't get through!!
