OK so com.apple.decmpfs should not be allowed, that's a miss and I'll have to fix it.

com.apple.ResourceFork is curious, could you print its hex value? I wonder if it is all
zero and should have been removed.

my mac (Mac mini M2, macOS Ventura 13.4) still panics while ejecting any other external USB disk

Do you per chance get a "Your mac restarted due to a problem, send report to apple?" when you boot up? if you do,
can I have the "stack" + "kext present in the stack openzfs load-address" line... ?

I‘m out for a short holiday trip until sunday, so I can't send you the info you asked for, before next week. What I can say for now is, that there has been no „problem report window“ after restart. But I have deactivated tailspin, so this might be the reason…. I will reactivate it when I‘m back and see, if I can get the crash report for you

So long….

Hello, back again...

Do you per chance get a "Your mac restarted due to a problem, send report to apple?" when you boot up? if you do,
can I have the "stack" + "kext present in the stack openzfs load-address" line... ?

Now I got the panic report, but there's no "stack" and no "openzfs load-adress" line... but I did not set nvram boot-args="keepsyms=1" anymore, due to a warning, that manipulating nvram parameters on Apple Silicon Macs could cause severe problems which lead to a complete re-installation of the system... Can I safely set this parameter???

The panicked task is PID 0 "kernel_task" on core 3, so not really informative...

Code: Select all
„xattr -l file.name“

The xattr "com.apple.decmpfs" is only present on some rare files (one is a screenshot, laying on my desktop).
Code: Select all
xattr -x -p com.apple.decmpfs file.name
says: No such xattr: com.apple.decmpfs. The same happens with com.apple.ResourceFork.

I checked some other files on my internal disk and the corresponding backup on my ZFS pool but couldn't find any good reason, why those files are copied over and over again by Carbon Copy Cloner. They seem to be absolutely identical! Even the nanosecond-timestamp is the same (stat -f %Fm file.name)! That's really strange...

but I did not set nvram boot-args="keepsyms=1" anymore, due to a warning, that manipulating nvram parameters on Apple Silicon Macs could cause severe problems which lead to a complete re-installation of the system...

This warning I found here: https://www.macworld.com/article/340211 ... 1-mac.html
(section "No SMC to reset, no NVRAM to zap (mostly)")

...and here: https://eclecticlight.co/2020/11/28/sta ... r-m1-macs/
(section "Verbose mode" and "Reset SMC/NVRAM")

In these two articles:
https://eclecticlight.co/2021/01/21/sys ... n-m1-macs/
https://eclecticlight.co/2022/01/22/exp ... ram-nvram/

they say, that
boot-args – any arguments to be supplied to the boot command, such as -v to engage Verbose mode when next booted (supplied as a string). Recent reports suggest that this no longer works, and changes should be avoided.

So, does anybody know how to get a more detailed panic report? Maybe "log show …" is the key, but I don't know which arguments I should pass to it...

does anybody know how to get more useful crash reports for OpenZFS on OS X on Apple Silicon Macs? nvram boot-args="keepsyms=1" doesn't work anymore, I guess (see my previous post) and I'm not courageous enough to test it on my working machine...

Here is the latest (not so useful?) panic report (created back in macOS Ventura 13.4). The machine crashes every time I eject another (USB) drive from Finder or commandline while the ZFS pool is online (imported/mounted). Beside a "normal" unencrypted mirrored pool, I have an encrypted dataset, if this is something worth knowing...:

Yeah it is quite difficult. If you get the line:

"Kernel Extensions in backtrace"
and it happens to have ZFS in it, you have the load address and can to the atos lookup with math. (More detail on the wiki).

Generally, I now look in /Library/Logs/DiagnosticLogs/ for *.panic file, as they can sometimes have resolved symbols.

Code: Select all
cat /Library/Logs/DiagnosticReports/Kernel_2020-07-27-133737_shinken.panic | grep macOSProcessedStackshotData | python -c 'import json,sys;print(json.load(sys.stdin)["macOSPanicString"])'

I have a new panic-report from version "OpenZFSonOsX-2.2.99-macOS-13-arm64"...
Again, the panic happened, when I ejected an external APFS-disk from finder.
OS version is macOS Ventura 13.5.2 (22G91), Macmini M2 Pro (2023), 32 GB ram.

Inside the report-window is a line "Kernel Extensions in backtrace:"

Code: Select all
Kernel Extensions in backtrace:
            dependency: com.apple.driver.AppleEffaceableStorage(1.0)[13E65512-32C3-3CF7-9C4A-2ECE150C6F91]@0xfffffe002ebff850->0xfffffe002ec048a7

ZFS is mentioned a little further down under "loaded kexts": org.openzfsonosx.zfs 2.2.99
Nothing more! A load adress is not given.

If you like, I can send you the whole report (by e-mail?)

The problem, that nearly every file is updated over and over again still persists. Now I use Carbon Copy Cloner to create backups. To APFS-volumes only changed or new files are updated, as expected. Do you have any idea what I'm doing wrong?

Here are my zfs tunings:
Code: Select all
kstat.zfs.darwin.tunable.zfs_arc.max: 0 -> 4294967296
kstat.zfs.darwin.tunable.zfs.xattr_compat: 0 -> 1
kstat.zfs.darwin.tunable.icp_aes_impl: cycle [fastest] generic aesv8  -> cycle fastest generic [aesv8]
kstat.zfs.darwin.tunable.force_formd_normalized: 0 -> 1
kstat.zfs.darwin.tunable.zfs.sha256_impl: cycle [fastest] generic armv7 neon armv8-ce  -> cycle fastest generic armv7 neon [armv8-ce]
kstat.zfs.darwin.tunable.zfs.sha512_impl: cycle [fastest] generic armv7 armv8-ce  -> cycle fastest generic armv7 [armv8-ce]

Thanks for your help!
