Boot with any Linux Live disk which support cryptsetup.

Then map the encrypted volume (e.g. hdc1):
# cryptsetup luksOpen /dev/hdc1 unencryptednode

Then 'fsck' the disk:
# fsck /dev/mapper/unencryptednode

That is it.

btw. strange you know the password for the encryption, but not for root?

Best,
