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

      I use BTRFS on everything too nowadays. The thing that made me switch everything to BTRFS was filesystem compression.

          I use zstd too, didn’t specifiy a level tho, so it’s just using the default. I only use like ⅔ of the disk space I used before and I don’t feel any difference in performance at all.

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

        I’ve run btrfs for years and never had a issue. They one time my system wouldn’t boot it was due to a bad drive. I just swapped the drive and rebalanced and I was back up and running in less than a half an hour.

        Corruption on power only regularly happened to me on xfs a few years ago. That made me swear to never use that fs ever again. Never seen it on my ext4fs systems which are all I have for years in multiple computers.

            Never had an issue with EXT4.

            Had a problem on a NAS where BTRFS was taking “too long” for systemD to check it, so just didn’t mount it… bit of config tweaking and all is well again.

            I use EXT* and BTRFS where ever I can because I can manipulate it with standard tools (inc gparted).

            I have 1 LVM system which was interesting, but I wouldn’t do it that way in the future (used to add drives on a media PC)

            And as for ZFS … I’d say it’s very similar to BTRFS, but just slightly too complex on Linux with all the licensing issues, etc. so I just can’t be bothered with it.

            As a throw-away comment, I’d say ZFS is used by TrusNAS (not a problem, just sayin’…) and… that’s about it??

            As to the OPs original question, I agree with the others here… something’s not right there, but it’s probably not the filesystem.

            Yes both BTRFS and Ext4 are vulnerable to unplanned powerloss when writes are in flight. Commonly knows as a write hole.

            For BTRFS since it use of Copy of Write, it is more vulnerable. As metadata needs to be updated and more. Ext4 does not have CoW.
