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.
Yeah maybe my machines are cursed
That is totally possible. I spent a month changing boards and CPUs to fix a curse on my main, unrelated to storage. In case you’re curious.
@avidamoeba @possiblylinux127 Does your ZFS not print on Tuesdays? https://bugs.launchpad.net/ubuntu/+source/cupsys/+bug/255161/
I feel like this one flew right over my head. 🥹
I doubt that. Some options:
The list is endless. Maybe BTRFS is more tolerant of the problems you’re facing, but that doesn’t mean the problems are specific to ZFS. I recommend doing a bit of testing to see if everything looks fine on the HW side of things (memtest, smart tests, etc).
I set the Arc cache to 4GB and it is working better now
