Sometimes a single slow HDD can cripple the performance of your entire system. You can spot one like this:

@demofox however, I appreciate the powerful chaotic energy of the phrase "fifty dollar three-dee printer"

@demofox sure thing :) 3D printing is a bottomless dive of fascinating interconnected technical problems that can burn your house down. At the zenith of my 3D printing hobby I had four printers (two frankenprinters and two industrial prototypes) and a salary from a 3D printer manufacturer. Then, for reasons, I burned out on that particular special interest and went off to live a simple life as a game developer.

@hackacad @dexter Hi Sven! Sure: initially I started managing the BSD Cafe's Mastodon media storage using Minio inside a FreeBSD jail on a server with traditional disks. When the media grew to around 200 GB (and it's a lot of small files), I realized that the performance wasn't great, so I decided to try both Garage and SeaweedFS. I set up two identical jails on the same host, one with Garage and the other with SeaweedFS, then I started copying the existing media using rclone, from one jail to the other, starting with Garage. Initially, everything was fine, but I realized that at around 60 GB, Garage started to fully utilize the machine's 6 cores and slow down noticeably. I left it running all night anyway, but in the morning it had copied just over another 10 GB. I stopped the process. I performed the same operation on SeaweedFS and the copy went smoothly and without issues until the end, at full performance. The approach of creating volumes and small external index files with offsets is decidedly suitable for this type of use. I tried some more times - same result. It has been up and running for a few months now without any problems. Furthermore, its modular structure allows you to replicate everything (for disaster recovery, backup, etc.) in "almost" real-time: you can connect a filer from one SeaweedFS setup to another (completely separate) and it will begin to replicate everything that is present and stay in sync. For this reason, I decided to continue using it and have implemented the same setup for the illumos Cafe as well.

@bbacc : è in casa con l'influenza e chiede consigli al fediverso su un film comico recente da guardare per passare il tempo
il fediverso: le elenca una serie sterminata di titoli ugandesi con sottotitoli in shwaili degli anni 60.
