A year ago I set up Ubuntu server with 3 ZFS pools on my server, normally I don’t make copies of very large files but today I was making a copy of a ~30GB directory and I saw in rsync that the transfer doesn’t exceed 3mb/s (cp is also very slow).
What is the best file system that “just works”? I’m thinking of migrating everything to ext4
EDIT: I really like the automatic pool recovery feature in ZFS, has saved me from 1 hard drive failure so far
Make sure you don’t have SMR drives, if they are spinning drives. CMR drives are the I ly ones that should be used in a NAS, especially with ZFS. https://vermaden.wordpress.com/2022/05/08/zfs-on-smr-drives/
From the article it looks like zfs is the perfect file system for smr drives as it would try to cache random writes
