OpenZFS on OS X

Obviously, it's not advisable to actually run a ZFS storage pool on an OS whose first developer seed came out 3 days ago. Still, I wanted to see if OpenZFS would even load, and it doesn't; what it does is this:

Code: Select all

Error Domain=KMErrorDomain Code=31 "Error occurred while building a collection:

    2: Could not use 'org.openzfsonosx.zfs' because: Failed to bind '_sprintf' in 'org.openzfsonosx.zfs' (at offset 0x558 in __DATA_CONST, __auth_got) as could not find a kext which exports this symbol

So, this is just a public service announcement to say, don't even try on Sequoia yet, because the kernel extension doesn't load. But it'd be interesting to see what happened if it could find something to replace the _sprintf function.

Clang has already been complaining for some time whenever it sees sprintf being used. You probably need to switch to snprintf.

The changelog for the most recent release (https://openzfsonosx.org/wiki/Changelog#OpenZFS_on_OS_X_2.2.2_2023-12-05) mentions "don't use sprintf".

I'm assuming you did the test with the latest version, so probably not all uses of that function have been removed.

Turns out I was not looking at the right place, the News & Announcements part of the forum has actually offered a release candidate for a new version for quite a while: zfs-macOS-2.2.3rc5.

Tested quickly on Beta 5, and I could import & export my pool on an external SSD, as well as read/write data on it.

Is there an intel vs arm build for Sequoia for testing?

just reporting that 2.2.3rc5 works for me on the release version of Sequoia (15.0). i did the OpenZFS update in Sonoma then upgraded to Sequoia.

Hello,
is it possible to have 2.2.3rc5 for intel platform?

There's a Catalina build for x64 of 2.2.3rc5 which should work on all newer platforms.

Installed the current Catalina build (Intel) from June, with Sequoia fixes, but had to do the following:
- the installer (over the previous build) failed
- /var/log indicated that it could not unload the kext already present
- rebooted at this point and placed it on the desktop
- installed successfuly

Hope this helps.

i have openbsd trauma that demands i use `vsnprintf` is that no longer a thing

trying an update now thanks for notes @xenophon
