Looks like some other filesystems were not cleanly unmounted. Could it 
be related ?

It depends what you mean by "usable".
If you just want to complete the init process, then comment out the 
/home line in /etc/fstab.

The first things you want to do is to check that /dev/md* exist and are 
active, and check the keyboard layout by typing the passphrases in 
cleartext.

Then you are a fool. Encryption means "I prefer losing the data than 
having it disclosed". I guess you didn't make a backup of the master key 
or the LUKS header with cryptsetup ?
