As stated in my comments here (but it seems no one is reading this blog post comments anymore ...) : https://blog.kobol.io/2020/10/27/helios64-software-issue/
- With 5.8.17 i have kernel panics.
- With 5.8.14 i have freeze.
So what to do in order to have a stable situation ?!
It seems to be "under load" (one freeze during RAID array being built, and several ones (with .14 or .17 kernels) while files were being copied thro
@jbergler I recently noticed the armbian-hardware-optimization script for Helios64 changes the IO scheduler to `bfq` for spinning disks, however, for ZFS we should be using `none` because it has it's own scheduler. Normally ZFS would change the scheduler itself, but that would only happen if you're using raw disks (not partitions) and if you import the zpool _after_ the hardware optimization script has run.
You can try changing it (e.g. `echo none >/sys/block/sda/queue/scheduler`)
