VCSA - Corrupted volume and cannot run FSCK

Hello,

My VCSA 6.0 box is telling me it cannot boot and I need to run FSCK on the volume.  Normally this is no problem but when I boot into maintenance mode (entering the root password) it takes me to the VMWARE shell with the file system in read only .  So I type

shell

and it tells me its disabled

I type shell.set --enabled True

and it tells me unknown command.

Please advise.
