Secure erase of disc drives

On a regular basis I need to resize these virtual discs, but not that often that I can do this from memory. This is a short procedure to do this: ls -l /dev/vgX/lvX # note down the major/minor numbers for later lvextend -L +50G /dev/vgX/lvX # adding 50GB to this volume ...

Encrypting FileSystem in Void Linux
The point of this recipe is to create a encrypted file sytem so that when the disc is disposed, it does not need to be securely erased. This is particularly important for SSD devices since because of block remapping (for wear levelling) data can't be overwritten consistently. The idea is that the boot/root filesystem containing the encryption ...
