Recover files on RAID5 with Extundelete?
So I've done a lot of reading and know this is my fault! However I still think there is a chance I can recover some files, so just wanted to ask here as a last resort. I have a 4 disk (4TB x 4) s...

extundelete won't work because the NAS uses btrfs for the data volume (not ext).
The RAID array for the data volume is /dev/md127
Ok thanks for this, are there any other options? I am currently looking at running photorec directly on that /dev/md127 device, but no option to look at a specific folder so its going to take some time!

Also StephenB is it possible to safely unmount /dev/md127 so i can try and run btrfs on it?
Yes. One option is to reboot the NAS in tech support mode.
After that you log in with telnet, using root as the username and infr8ntdebug as the password.
After you are logged in, you'd enter
# rnutil chroot
which will both start RAID and chroot. But it will not mount the data volume.
Is it possible to do this via SSH, as obviously I'll need SSH access to run the btrfs restore utility.
I found a port about creating a ~/.tech-support file and rebooting, is that going to acheive the same purpose?
