Strange isos- inside /dev/mapper files


Hi folks,

I just installed wheezy on my gaming hardware to see what new stuffs coming up. During the installation while partitioning the system I saw some akward files under /dev/mapper but did not really care about it. (Should tell you that the installation is on a fake-raid through an nvidia mobo sata raid controller. dmraid=true at the boot prompt activates /dev/mapper).
But now as the system is up an running those files are still there. And I can't find anything about this. Maybe someone has any clue where I can look further.

Here's the listing of /dev/mapper. dm-7 to dm-9 are those that I have no clue about.
Code:
root@mainframe:/dev/mapper# ls -lha
total 0
drwxr-xr-x  2 root root      320 Nov  6 12:31 .
drwxr-xr-x 16 root root     3.6K Nov  6 14:12 ..
crw------T  1 root root  10, 236 Nov  6 12:31 control
lrwxrwxrwx  1 root root        7 Nov  6 12:31 isos-iso--apache -> ../dm-8
lrwxrwxrwx  1 root root        7 Nov  6 12:31 isos-iso--debian -> ../dm-9
lrwxrwxrwx  1 root root        7 Nov  6 12:31 isos-iso--endian -> ../dm-7
lrwxrwxrwx  1 root root        7 Nov  6 12:30 nix-debian--root -> ../dm-2
lrwxrwxrwx  1 root root        8 Nov  6 12:31 nix-debian--usr -> ../dm-10
lrwxrwxrwx  1 root root        8 Nov  6 12:31 nix-debian--var -> ../dm-11
lrwxrwxrwx  1 root root        8 Nov  6 12:31 nix-home -> ../dm-12
lrwxrwxrwx  1 root root        7 Nov  6 12:31 nix-swap -> ../dm-6
brw-rw----  1 root disk 254,   0 Nov  6 12:30 pdc_djjieidcae
brw-rw----  1 root disk 254,   1 Nov  6 12:30 pdc_djjieidcae1
brw-rw----  1 root disk 254,   3 Nov  6 12:30 pdc_djjieidcae2
brw-rw----  1 root disk 254,   4 Nov  6 12:30 pdc_djjieidcae5
brw-rw----  1 root disk 254,   5 Nov  6 12:30 pdc_djjieidcae6
And the extract of ../dm-*
Code:
root@mainframe:/dev/mapper# ls ../dm-* -lha
brw-rw---T 1 root disk 254,  0 Nov  6 12:31 ../dm-0
brw-rw---T 1 root disk 254,  1 Nov  6 12:31 ../dm-1
brw-rw---T 1 root disk 254, 10 Nov  6 12:31 ../dm-10
brw-rw---T 1 root disk 254, 11 Nov  6 12:31 ../dm-11
brw-rw---T 1 root disk 254, 12 Nov  6 12:31 ../dm-12
brw-rw---T 1 root disk 254,  2 Nov  6 12:31 ../dm-2
brw-rw---T 1 root disk 254,  3 Nov  6 12:31 ../dm-3
brw-rw---T 1 root disk 254,  4 Nov  6 12:31 ../dm-4
brw-rw---T 1 root disk 254,  5 Nov  6 12:31 ../dm-5
brw-rw---T 1 root disk 254,  6 Nov  6 12:31 ../dm-6
brw-rw---T 1 root disk 254,  7 Nov  6 12:31 ../dm-7
brw-rw---T 1 root disk 254,  8 Nov  6 12:31 ../dm-8
brw-rw---T 1 root disk 254,  9 Nov  6 12:31 ../dm-9
Thanks in advance for any input.
