    I didn’t come up with this idea myself, this is straight from OpenBSD disk setup guide (which I personally trust as a good source of info) :

    Encrypting External Disks

    This section explains how to set up a cryptographic softraid volume for an external USB drive. An outline of the steps is as follows:

    • Overwrite the drive’s contents with random data

    […]

    # dd if=/dev/urandom of=/dev/rsd3c bs=1m
    


  • Well as I see it, it will just do a lot of write operations to your disk, which might eventually damage it if you do it a lot (just like any write operation done on a disk). However, this specific command isn’t bad per se, and is even technically a good thing to do for preparing to full disk encryption.












  • My main issue with NFS is that it’s been unreliable in my case (multiple servers connected over wireguard, over internet). Which cause locks and latency for the applications that read/write to it (Matrix server, distributed repository, …).

    Of course if you can afford connecting the NFS server directly to the servers, that’s perfect but I’m more on the worst case scenario ^^
