I just set up 2 data HD on RAID 1 in Ubuntu 12.04 (soft-raid), they are ext4. However I can't figure out how to remove permissions on these drives to read and write. I tried using
sudo chmod ugo+wx /
However it didn't work. Also tried: sudo chmod -R 777 * However, there are no files, and the permission needs to be set at the drive level, not files and directories.
Finally, I tried downloading pysdm
But does not seem to work because drives are set in RAID.
Any suggestions?
