About a year ago I switched to ZFS for Proxmox so that I wouldn’t be running technology preview.
Btrfs gave me no issues for years and I even replaced a dying disk with no issues. I use raid 1 for my Proxmox machines. Anyway I moved to ZFS and it has been a less that ideal experience. The separate kernel modules mean that I can’t downgrade the kernel plus the performance on my hardware is abysmal. I get only like 50-100mb/s vs the several hundred I would get with btrfs.
Any reason I shouldn’t go back to btrfs? There seems to be a community fear of btrfs eating data or having unexplainable errors. That is sad to hear as btrfs has had lots of time to mature in the last 8 years. I would never have considered it 5-6 years ago but now it seems like a solid choice.
Anyone else pondering or using btrfs? It seems like a solid choice.
Since most people with decently simple setups don’t have the described problem likely somethings up with your setup.
Yes ifta old and yes it’s complicated but it doesn’t have to be to get a decent performance.
I used to run a mirror for a while with WD USB disks. Didn’t notice any performance problems. Used Ubuntu LTS which has a built-in ZFS module, not DKMS, although I doubt there’s performance problems stemming from DKMS.
I have been trying to get ZFS working well for months. Also I am not the only one having issues as I have seen lots of other posts about similar problems.
I don’t doubt that you have problems with your setup. Given the large number of (simple) zfs setups that are working flawlessly there are a bound to be a large number of issues to be found on the Internet. People that are discontent voice their opinion more often and loudly compared to the people that are satisfied.
