Segmentation Fault 11 using zdb on High Sierra

Postby Double K » Mon Nov 06, 2017 3:26 pm

Hi Folks, first post, but long time user of ZFS on OS X.

Did a fresh install of High Sierra on a Mac Pro (10.13.1)
Installed Java, XCode, and Homebrew (with smartmontools)
Installed O3X 1.7.0
Can create pools with no problem

However, when I run zdb, I get "Segmentation fault: 11"
Anyone else having this issue?
Any suggestions on how to fix?

PS - zdb works fine on O3X 1.5.2 on Yosemite 10.10.5 on a macmini for me

Just to update this post, I downgraded to Sierra 10.12.6 and installed O3X 1.6.1 and I don't have any issues with running zdb.

If anyone is successfully using zdb on High Sierra with O3X 1.7.0, please reply to this post. I'd like to understand if this is a "local" issue.

The zdb is a known issue with the compile of 1.7.0 - the fix is here: https://github.com/openzfsonosx/zfs/com ... 17cffe10f1
and will be corrected in the proper release, which we wanted out quickly, but the on-disk crypto changes came up first, and we don't want to release something when we know we have to change the on-disk format.
