  • Simplest put, a fedora immutable usually keeps two images, the one you’ll boot into next reboot, and the one you’re running. If a rpm-ostree update hasn’t been run it’ll be the one you’re running and the last one. My bazzite (heavier than silverblue I guess) images are ~ 14Gb, you need room for three (the two you’re using and room for downloading the next) plus 3% of your hard drive because fedora says so, so 3*14 = 42 + .03 * 240 = 42 + 7.2 = 49.2 =~ 50Gb.

    Wait a sec, when I actually do a

    sudo du -sh /sysroot/ostree/deploy/fedora/deploy/*

    I get 14Gb for my previous one and 2.1Gb for my current one, so there’s some diff black magic fuckery (ostree chunking) going on, which makes sense because it’s not taking that long to download. So 50Gb would be super safe, you might get away with 25 depending on how different the two images are (i.e. how much has been updated), but updating to the next major fedora version (e.g. 42->43) would be iffy.

    Upshot is, it shouldn’t have filled to 90-something in the first place (maybe before ostree chunking, but even then), but if you end up with a lot of entries in your GRUB they’re all taking a notable chunk of space and you’ll need to purge some.


  • Valid. In fact the (thunderbolt) power port will self-destruct over a year or two without a firmware update (overheats), Lenovo used to replace 'em for free, not sure what the situation is now. I was lucky and got mine new in box (but at the second hand price) after the bios update was available, but it’s something you should look out for when buying second hand. FWIW there’s also a power port in the dock connector.

    First up… backups…

    You’ve got all your data on a single 8TB external drive?

    This. RAID IS NOT A BACKUP !!! Sorry for shouting, but it’s that important. It’s a main storage tolerant of disk failure, you still need backups or you’re one bad ‘rm -rf’ away from losing data.

    First get that second 8Tb, or better yet a 16+Tb (see serverpartdeals.com or your local equivalent for good prices on manufacturer recertified drives) so you have room to grow. Now copy that 8Tb onto it and disconnect it from your computer. Congratulations, you have a cold backup and are pretty well protected from data loss, much better than a RAID.

    You can now think about a NAS with confidence, but preferably before that get another drive copy your data again and take it to a friend / relative / safety deposit box (even bury it in the back yard in something waterproof). Now you have a 3-2-1 backup strategy and you’re pretty damn well insulated against data loss.

    TLDR: Backup first, NAS later.
