Could the /dev/dasdb2 filesystem have been an LVM "volume group"?
/dev/mapper/VolGroup00-LogVol00 would be the type of things you might see
for LVM volumes.
My system shows the following in df (truncated because I love loop-back
mounts...)
rockhopper:~ # df
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/mapper/system-rockhopper
8589044 7863536 725508 92% /
tmpfs 405156 4 405152 1% /dev/shm
/dev/dasda1 86380 14756 67168 19% /boot
/dev/mapper/vg_iso-lv_media
27355500 25573528 1504100 95% /iso
/dev/mapper/vg_local-lv_ibmitm
6713132 220156 6492976 4% /opt/IBM/ITM
/dev/dasda1 is my /boot, and everything else are LVM volumes.
Try the command "pvdisplay /dev/dasdb2" to see if it is a physical volume
that was part of a volume group. If it was, then possibly try "vgscan" to
see if it finds /dev/dasdb2 as part of a volume group. The big problem might
come if the volume group has the same name as the one on the system you've
attached it to....
