How do you mean? There is one disabled optimization for a heavy ZFS usage in the code of my kext, but it haven't been tested yet. If you're interesting, i may give you a build where it's enabled.
Hi, thanks for the reply. As I am still at the experimental stage, I'd be happy to help try anything out, no risk to my "production" deployment ;-)
To be clearer tho on my experience, I am currently using the RR2720 with whatever native drivers there are in Mavericks. I had a look through the default kexts, but couldn't see which one it was using. I know that strictly speaking it's not supported, but the eSATA version is, and they are basically the same card afaik.
But the card seems to only work under Winbloze, and fails under OSX or Linux even without ZFS. I kick off a large copy from two disks on the controller, and it inevitably fails one of the disks, even though they otherwise seem ok. They can be brought back online etc, no issues.
I thought it might have been something in the firmware, as you used to be able to flash the v1.0 of these cards to a non-raid (HBA mode?), but that can't be done with the v2.0 that I got, and as it works in Windoze, it can't be physical incompatibility.
I did spot a read / write timeout parameter in the AppleLSI kexts, appears to be 30s. I thought if there was something similar in the RR kexts, and ERC/TLER on the drive was less than this, that the drive could fail out before the driver did, causing the issue?
I haven't seen anything special to the Mavericks support too.
Maybe worth to ask here? http://www.insanelym...sx86-solutions/
Had a look there, looks like the IBM BR10i might be worth a punt, thanks for the pointer.
