Most likely it come up in a "something is broken, bplease try to fix it
manualy" state

The mount command takes it's information from /etc/mtap and not from
/proc, so most likely the console message was something like "unable to
run fsck on /dev/bla" please enter root password and try to fix it,
system will reboot after you left the shell.

possible there are backups in /etc/lvmtab.d, but maybe not.

It would realy help, what the system told you when it booted.

A "simple" fix might be to reboot and pray :-/, but this might fu**up
everything.

Unfortunately I've not enough informations to help you further :-(, and
I don't know how stable yast2 is so I can only guess what you might be
able to do to fix anything, but my guesses might be way off.

Cu,
