Oh, you want to do it nondestructively. Sotty, missed that.
There is. But you need to calculate the position of the
metadata block right and give the correct offset to dd_rescue.
Better avoid that, since it is likely to go wrong on the first
attempt.
You can mount the disks individually by first breaking
the RAID set. Depending on the version of the RAID tools
you have, ''raidstop'' or ''mdadm'' with some option is
what you are looking for. As soon as the raid is stopped,
you can use an ordinary mount to mount the individual
disks or paritions. The next autodetect will assemble the
RAID though.
Another thing that may prevent autodetection is setting the
partition type back from "fb" (raid autodetect) to "82"
(or was it "83"? Don't remember, but is marks an ordinary
Linux parition). This only prevents auto-start/assembly by
the kernel, not by some additonal scripts your partition
may have.
