Thank you, now it is OK!! :-) I noticed that not even swap space was working. Then giving a: dmsetup info it reported: Name: sil_aeaddfbjaaeb9 State: ACTIVE Tables present: LIVE Open count: 2 Event number: 0 Major, minor: 254, 7 Number of targets: 1 one per partition. So partitions where there, simply nodes where missing. Thus, a: dmsetup mknodes ... made devices usable again. While, using this: dmraid -ay made some mess, since it created cloned devices like this Name: sil_aeaddfbjaaebb9 notice it is just like the one above, but it has two "b"s before partition number. It seems like if dmraid detects another sets and puts it into /dev/mapper. I've appended this to rcS.d/S04udev (I've just learned that S04 is the 4th script being executed during boot in Debian): dmsetup mknodes and now it works ok with the first names (just one "b" at the end). Also the swap space is there and working!! Now I only wonder if this is too hacky or I can leave things like this. Thank you again, kind regards.
