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
Where are you copying to / from?
Duplicating a folder on the same NAS on the same filesystem? Or copying over the network?
For example, some devices have a really fast file transfer until a buffer files up and then it crawls.
Rsync might not be the correct tool either if you’re duplicating everything to an empty destination…?
Same NAS, same filesystem on an SSD without redundancy
Still the same, or has it solved itself?
If it’s lots of small files, rather than a few large ones? That’ll be the file allocation table and / or journal…
A few large files? Not sure… something’s getting in the way.
