I used to use the "raidstart" command to mount an existing array. Since while that command is not in Debian distribution no more, I was looking for a way to do it with mdadm.

In a hurry I ran "mdadm -C" thinking that it was one of the steps for mounting an
existing array. Now I know tahat the thing i need is "mdadm -A" but I can't mount my array no more, because now fsck.ext2 can't find the superblock on the array!

Did I forever ruin my raid array? Is there a way to recover my
reiserfs superblock and the original array data?

Thanks

Here is the solution:

I wrote to Neil Brown, the author of mdadm utility:

He said:
You can probably just re-do it.
Your mistake should not have corrupted any data on the devices, on the
meta-data (super blocks).
So try
mdadm -S /dev/md0 # to stop the array if it is still running
mdadm -C /dev/md0 -l5 -n3 -p ls -c 32 /dev/hde /dev/hdf /dev/hdg
