You should check the above filesystem errors and try to fix them. I would
review the mentioned file "/var/log/fsck/checkfs".

Some thoughts...
It seems you are using a fakeraid or logical volumes setup (/dev/
mapper/...). Can you explain how are the disks configured? How many disks
in use, are they attached to a hard/soft raid controller or inside a
volume? :-?
How did you create the partitions, from Solaris or from Debian installer?

That dm* stands for "device mapper", a framework for block devices. I
dunno about that "format" utility for Solaris but "cfdisk" could be
useful in this case ("man cfdisk" for details).
