Kernel Panic Issues after installing 2.0.0 RC5 on Big Sur

[Jimbo]

Ok, so version #6 installed fine on Parallels VM (w/Xeon) - no panics and no panics on boot.

The good:

• Created Data Sets and loaded data.
• Created ZVOL formated HFS+ and loaded data.

Oddness with volume icons on the desktop:

• Dataset volume was "default" disk icon, changed to "shared folder" icon when permissions of the dataset were changed
• ZVol formatted as HFS+ had *no* icon at all
• Another ZVol formatted as APFS+ had *no* icon at all
• Icons can be changed - change seems to stick

Export/Import:

• Export pool:
  
  • Did not unmount ZVOLs (change in behaviour?) - export succeeds after manually unmounted the ZVOLs
  • Generated OS warning about root Dataset not being unmounted cleanly.
• Import pool
  
  • Manually (once) all good, but only once. Subsequent behaviour from the command line is like "on boot" below. Edit: this is inconsistent - I have had successful "import -a" but not consistently.
  • On boot - not all ZVOLs mounted (appear as unformatted - as articulated here

Then a panic while doing lots of deletes:

Code: Select all

Edit 2: Panic is repeatable (identical trace) - deleting a copy of XCode placed in the Trash.

[Jimbo]

Following on from the post above, the panic also happens when destroying a ZVOL or Dataset:

Cheers, that is interesting. Looks like I should check zfs_zrele_async and make sure it is correct. There appears to be a zvol race still but not quite as bad as before.

[Jimbo]

Ok, #7 build on Parallels VM (w/Xeon)...

• Install and reboot - ok.
• Import pre-existing pool - ok.
• Create Dataset and ZVOLs - ok.
• Loaded data - ok.
• Export pool - as before (did not unmount ZVOLs - export succeeds after manually unmounted the ZVOLs, fenerated OS warning about root Dataset not being unmounted cleanly).
• Import pool - as before (inconsistent discovery/mounting ZVOLs).
• Delete data - didn't immediately panic, but got ~138000 files into XCode and then Finder(?) started losing the plot and each application or shell I started interacted with would beachball-of-doom to the point the VM became unresponsive.

Any thoughts on how I could gather any useful info on that?

Cheers!
James

[lundman]

Since you mentioned Catalina behaves the same, I will run some local tests here - it is much easier to work/debug on Catalina.

If you do get hangs, and beachballs, the thing to run is "sudo spindump". Will show the stacks and what they are doing. Alternatively,
explain what you did so I can try replicate. I will try putting xcode in trash and empty.

[Jimbo]

Thanks @lundman. I'll try sudo spindump if I can, however, the VM was so unresponsive that I couldn't even SSH into it - it was still "alive" though.

Ok... while typing this I was running another delete.

Things ran along for ~144000 files in XCode then I noticed the CPU drop right off... stayed there for a while then spiked backup. When I run 'sudo spindump" I was promptly told:

Code: Select all

zsh- too many open files in system

...

Once I've recovered the VM, I'll try copying and deleting XCode on a non-ZFS volume.

Cheers!
James

[lundman]

Too many files? Hmmmmm, that does sound connected to reclaim - I'll give it a whirl

[Jimbo]

Mmm... so a copy of XCode on the boot disk and a copy of XCode on an external ExFAT drive all deleted ok.

Imported my test pool and recommenced emptying the trash and got ~110000 files in and "too many open files" and things went pear-shaped.

Cheers!
James

I'm still getting the same kernel panic in build 7.
I've searched for instructions on how to enable keep symbols on Big Sur but so far haven't found something that didn't just give me security errors, I saw mention of using a recovery partition boot which I've never done - but when I google the steps for that people say its no longer in Big Sur.

So... unless someone can give me step by step instructions, this is all you are going to get.

1. Turn you machine off.
2. Turn your machine on and immediately hold Command-r on the keyboard. Let go when you see the progress bar.
3. This should boot into Recovery Mode.
4. Pick your user, click next and enter your password.
5. Select the Utilities menu and open a terminal, then:
   

   Code: Select all

   nvram boot-args=“keepsyms=1 debug=0x146”

6. Exit terminal.
7. Choose Restart from Apple menu.
8. Done.
