OpenZFS on OS X

OK that was entirely my bad, here's the PKG you really want.

strings -a /Library/Extensions/zfs.kext/Contents/MacOS/zfs|grep -i macos
zfs-macOS-2.1.99-103-g6dfb6ddcc9-dirty

We could blame Apple for forcing you to have to notarise.

I swapped the switches -L and -l around, and ironically, I invented them for my script in the first place,
so I really should know better

Hmm this might no longer have the debug printfs, so lets hope I actually got it right this time.

Success!

Code: Select all

Would you be able to do a Monterey build at some point or would you want and do a 2.1.1 release with this in?

Thanks.

I could spit out a Monterey build, but I think this Catalina build should work fine?
I do want to release a 2.1.1 - need to check what else needs to be fixed for it though.

Yes, it's installed correctly on a Monterey VM.

Is there anything interesting in ZOL 2.1.1 or 2.1.2 that would be worth pulling in?

That PKG should also have your arcstat - you can check it looks ok

Yes thanks, arcstat/arc_summary working now.

RE: avx (from GitHub), Doesn't look like it's there. Wasn't there an issue with getting the AVX assembler stuff to work on 1.9.4 and it wasn't enabled?

1.9.4 never had AVX - openzfs added it after. I think it is not brought in as it needs to be checked over, make sure it doesn't trash the wrong Registers, since the
volatile registers are different between Linux and macOS.

Similarly, arm64 assembler also needs to be over.

The encryption read/write performance is really poor on my m1 Mac. I'm eager to get this problem fixed. (The read speed is about 15 MB/s). When will the new patches been released?
Thanks!
