OS crash on cat/mv/cp of a file in zfs

[bornav]

Does anyone have ideas on how i could debug what crashes the os when i touch a specific file in encrypted zfs share

what works mv in the same directory(rename)
what does not:
- mv different dir
- cp
- cat

what happens when try it,
instant reboot, nothing is logged in journalctl in the last moments of the OS

 

[bornav]

additional notes, running scrub on the share completes normally, no issues
drive have no errors, manually running smart, everything normal

What version of TrueNAS SCALE?

What is your hardware?

Does this occur over SMB?

More context and information would be welcomed.

 

[bornav]

running 23.10.1
custom hardware, cpu: 5950x drives are nvme 4 of them in raid z, 16Gb ram
tried it with smb, nfs, the example above is directly over shell over ssh

also was running virtualized under proxmox, manualy booted to the root drive directly, same situation

tried it with smb, nfs, the example above is directly over shell over ssh

So copying a file over SMB crashes the entire server?

 

[bornav]

yes, over smb cant get to copy, crashes on rightclick, so even reading the file nukes the system

 

[bornav]

my guess is it is not directly truenas related, but ether kernel, or zfs, but have no clue how would i debug it, since there are no logs(at least i cant find them)

 

[winnielinnie]

Did you manually change the permissions on the top-level root dataset by any chance?

Otherwise, this would need to be submitted as a bug with a debug attached to the ticket. (Since the underlying issue could be something lower-level.)

 

[bornav]

If i did, don't remember. But should be default

 

[winnielinnie]

I'd file a bug report then.

Under no circumstance should your server crash simply because you're copying files over SMB (let alone just right-clicking a file!)

 

[bornav]

Yes that makes sense

Thank's for the help
