I want to purge storage data from SAN which accumulates to 10 TB. The storage is mounted as mount-points on a system for which it is visible I was recommended by a friend to use winscp But I don't think the tool is efficient to such an extent. I appreciate if I can be recommended a tool or command line which can help me perform this job. Thanks

  • Purge as in rm -rf /*? Or securely erasing everything? – Daniel B Feb 27 '14 at 15:46

Login with ssh, unmount the disk, reformat it.

  • If you are on Windows use Putty to ssh in NAS.
  • Once logged in, you'll have to find the drive with mount command.
  • Unmount the drive with unmount command
  • Format the drive with mkfs
  • Mount it back using mount again

man command_name would show a command reference

  • With what tool or tools would one do this? – Kevin Panko Feb 27 '14 at 14:56
  • Depends on the filesystem. For everything ext, that would be e2fsprogs. reiserfs tools are provided by reiserfsprogs. Generally, these will already be installed. Short version: umount /dev/sdx1 && mkfs.ext4 /dev/sdx1 && mount /dev/sdx1 – Daniel B Feb 27 '14 at 15:49
