OpenZFS on OS X

The Modify/Change time stamp is incorrect after upgrade to OpenZFS on OS X 2.0 on macOS Big Sur 11.2.2. It works fine on regular APFS volume. This only happens on ZFS volume. "touch" command can update Modify time stamp. Could you share with me your suggestion?

Tests: Create time.txt using vi on both ZFS volume and APFS volume.

Time Zone: GMT+8

on ZFS volume

Code: Select all

# stat -x time.txt
  File: "time.txt"
  Size: 0            FileType: Regular File
  Mode: (0644/-rw-r--r--)         Uid: (    0/    root)  Gid: (   20/   staff)

It works fine for me with OpenZFS on OS X 2.0 on macOS Big Sur 11.2.1 (and it's hard to believe that 11.2.2 would make a difference). I never upgraded from an earlier version of ZFS, if that'd make a difference.

Might be related to the date problem mentioned in the project page. I'll research when I find time

Thank you.

Please feel free to let me know if any additional tests or information is needed.

OK, I am hoping the date/time thing has been resolved with today's build.

Thank you so much. The pi date (2021.03.14) version of 2.0 fixed this time stamp problem.
