This morning I decided to run some tests on bcachefs, which I hadn't tried out until today. Of course, I wouldn't trust it yet with important data. However, a couple of things impressed me: the background compression and the ability to use devices as cache. There's also the option to mix devices of different sizes, and reads will always be performed from the fastest device. If ZFS had these features, it would be wonderful.
People are standing in the back & sitting on the floor to see the wonderful Tomas Vondra #PostgreSQL talk at #pgconfeu about “Postgres vs. Linux filesystems” and not only is Tomas expert in his field and a good speaker, he is also an organizer of this event! #Postgres#Linux#filesystems#conference
So after reading up on #filesystems, I've attempted to put #UDF on my microSD. Whilst it is best known as the filesystem on CDs/DVDs, you can put it on USB storage devices as well. It does have some caveats when you do (you have to jump through some hoops to have the best compatibility¹).
I've tried to do it manually, but this¹ script did the job (it wasn't verbose about it); next step /etc/fstab
This allows extra cursed shit like a an encrypted & RAID-5 running NTFS - Tho that won't be useable by anything but Linix and I disrecommend it almost as hard as mixing hardware RAID controllers and/or dmraid with ZFS.
