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

FWIW lvm can give you snapshots and other features. And mdadm can be used for a raid. All very robust tools.

Yes but BTRFS can this out of the box without extra tools. Both ways have their own advantage, but I would still prefer BTRFS

I'm in BTRFS, and wish I wasn't.

Booting into a failed mdadm RAID1 is normal,

whereas booting into a failed BTRFS RAID1 requires competent manual intervention, and special parameters given to the boot-kernel.

mdadm & lvm, with a fixed version of ZFS would be my preference.

ZFS recently had a bug discovered that was silently corrupting data, and I HOPE a fix has been got in.

Lemme see if I can find something on both of these points..

Never had problems, but I wish you all the best for your ZFS problem 🤗
