photorec on raid volume

I have a nv+ that I'm trying to recover some deleted files on, it's a raid 5 with 4 1T disks, the volume is 2.7T with about 100G of used space (it was only online for about a week). I unmounted the raid volume as soon as it happened, and as far as I know no additional writing has been done to the volume. I downloaded the qemu sparc image, and updated the e2fsprogs to 1.4.2, then compiled a static build of the latest testdisk release, getting static sparc binaries of testdisk and photorec that run on the nv+ (I can share them if anyone is interested). I've pointed photorec at /dev/mapper/c-c. I've also tried looking at /dev/md2 and testdisk/photorec don't see the the ext3 partition. photorec has completed pass 0 of the 2.7T volume, with no sign of finding the filesystem from what I can tell, now it's in the middle of pass 1 with no results. Am I totally off base with this?

I'm sort of confused by:
/dev/md2
/dev/c/c
/dev/mapper/c-c

I have a loose understanding that the raid is /dev/md2, there's volume group c, and and lv /dev/c/c... just trying to figure out where to point photorec to do it's thing before giving up.

Thanks.

Re: photorec on raid volume

Any luck with this? I have the same problem, a lot of data lost and I can not figure out the device to recover the data from.
I have scanned the /dev/c/c device with the tool photorec without any luck.
Could anyone please help me on this?

Thanks,
