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
How full is your ZFS? ZFS doesn’t handle disk filling and fragmentation well.
Around 70% full with 10% fragmentation
At around 70%, fragmentation issues start becoming apparent with ZFS IIRC. Though they shouldn’t be this apparent.
