[Discuss] Update on Raspberry Pi4 ZFS Problems

[kentborg at borg.org (Kent Borg)]

[Background: Running ZFS on spinning HDs on a Rasperry Pi 4 was giving 
me I/O errors.]


Since I last posted here I tried:

- Exact same file copying torture test, using the exact same drives, 
hooked up to my AMD64 notebook, and they worked great. (Let's hear it 
for having a machine with enough USB-C ports.)

- Exact same torture test, but using the powered USB-C hub, connected to 
my notebook, and it worked.

- Exact same torture test, connected to a Pi 4's slow USB port..and it 
worked.


So what doesn't work is the high speed USB ports on my Pi 4, doing ZFS.

Grrr.


For what I am doing, the slow ports will plenty fast, I need to get this 
thing working. I'm going to try to plow forward.

Thank you all very much for your help in this.
