  • In all seriousness, digging tunnels is a military tactic that gets some use sometimes. The Russians have done it in the southern part of Avdiivka. I haven’t heard of a case where militaries used an actual tunnel boring machine, though.

    Tunnel boring machines are not just extremely expensive, they’re also extremely bulky and highly visible when on top of the ground. If you ship one to where you want to start your tunnel, there is a high risk that enemy intel will spot it, ruining the surprise.

    The actual digging is extremely slow, meaning there is no way of knowing whether the tunnel will even still have some tactical use when you’re done.

    Once you emerge on the other side, it won’t be long until the enemy notices your exit and does something about it, like bombarding it, stationing troops there or sending something of their own back through the tunnel. That means even if you succeed, you only have a very short window to do something with your tactical advantage, and said something will very likely be a suicide mission.

    Tunneling through the loose mud of Ukraine would not be easy. You can do it if you send a work crew after the machine to immediately build strong walls behind it, but that would be even slower and more expensive.

    All in all, it would just be more useful to use either much smaller and shorter tunnels that don’t use tunnel boring machines or utilize some form of artillery or drones to achieve the desired effect behind enemy lines.




  • Several years ago now. On at least two of those tries, after maybe a month or some of daily driving, suddenly the fs goes totally unresponsive and because it’s the entire system, could only reboot. FS is corrupted and won’t recover. There is no fsck. There is no recovery. Total data loss.

    Could you narrow it down to just how long ago? BTRFS took a very long time to stabilise, so that could possibly make a difference here. Also, do you remember if you were using any special features, especially RAID, and if RAID, which level?


  • Out of interest, since I’ve not used the “recommended partion setup” for any install for a while now, is ext4 still the default on most distros?

    I recently installed Nobara Linux on an additional drive, because after 20 years, I wanted to give Linux gaming another shot (works a lot better than I had hopes for, btw), and it defaulted to btrfs. I’ll assume so does Fedora, because I cannot imagine Nobara changed that part over the Fedora base for gaming purposes.



  • Dunno about ideal, but it should work.

    It does have quite a bit of overhead, meaning it’s not the fastest out there, but as long as it’s fast enough to serve the media you need, that shouldn’t matter.

    Also, you need to either mount it manually on the command line whenever you need it or be comfortable with leaving your SSH private key in your media server unencrypted. Since you are already concerned with needing to encrypt file share access even in the local network, the latter might not be a good option to you.

    The good part about it is, as long as you can ssh from your media server to your NAS, this should just work with no additional setup needed.
