Ext4 (for my laptop and stuff) and ZFS (as mirrors or raidz2 for my proxmox host and data).
ZFS. I want snapshots, volumes, encryption etc. btrfs fucked me over too often. Also I prefer the semantics of the zfs and zpool utils and the way mount points are handled. Thanks to ZFSBootMenu I can even have /boot as a zfs volume and have it therefore incluced in my snapshots. And did I mention that all of that is encrypted? Anyway. Love it.
ZFS raidz1 or raidz2 on NetBSD for mass storage on rotating disks, journaled FFS on RAID1 on SSD for system disks, as NetBSD cannot really boot from zfs (yet).
ZFS because it has superior safeguards against corruption, and flexible partitioning; FFS because it is what works.
@Hopfgeist @sam I prefer RAID10 on rust.
What are the advantages of raid10 over zfs raidz2? It requires more disk space per usable space as soon as you have more than 4 disks, it doesn’t have zfs’s automatic checksum-based error correction, and is less resilient, in general, against multiple disk failures. In the worst case, two lost disks can mean the loss of the whole pack, whereas raidz2 can tolerate the loss of any 2 disks. Plus, with raid you still need an additional volume manager and filesystem.
