Hello,
This weekend I upgraded my Monterey machine from 2.1.0 to 2.1.6. I also upgraded my pool, and changed the checksum from `sha512` to `blake3`. In hindsight this was too many changes at once, but I've had such good luck with OpenZFS on OS X over the past decade that I proceeded without fear.
However, since this upgrade several things happened within 48 hours:
1. ZFS now thinks one of my drives is busted and marks it as `REMOVED` from its mirror.
2. When trying to copy files from a filesystem in the pool (even when imported with `readonly=true`), the kernel panics after just a few minutes of `rsync`.
I can't find any logs on my system relating to these crashes, but most were about "corrupted heap" and one was about "NMI timeout" or something along those lines.
So I have a few questions:
a. Can I somehow undo the upgrade of my pool and revert back to 2.1.0? It was rock stable.
b. Is there any debug version of 2.1.6 I can run to provide better feedback in order to help track this problem down?
Thanks,
John
