cablespaghetti.dev is a Fediverse instance that uses the ActivityPub protocol. In other words, users at this host can communicate with people that use software like Mastodon, Pleroma, Friendica, etc. all around the world.
This server runs the snac software and there is no automatic sign-up process.
Lesson in #Kubernetes today - if you've got a bunch of users with some common very large container images, the default overlay might eat up your rootfs on your worker nodes, but #btrfs can be a significantly more quicker and efficient alternative.
TIL that #btrfs will happily run into a "no space left on device" wall with no possibility to write metadata anymore (which is needed for balancing and thus getting out of this situation) 🤦
(btrfs haters and #zfs enthusiasts incoming in 3... 2... 1...)
UPDATE: Solution is to `btrfs device add /dev/anEmptyDevice /<btrfsMountpoint>`, then run something like `btrfs balance start -dusage=5 /<btrfsMountpoint>`
I tried tuning various parameters but after some reading came to the conclusion that lots of small files with very little RAM is about the worst case scenario for XFS.
