Permissions errors only when deleting files/folders

[furistar]

System

Windows 11 25H2
OpenZFS on Windows 2.4.1rc10

Describe the problem you're observing

All file/folder deletion requires administrator privileges regardless of ownership or NTFS permissions

Describe how to reproduce the problem

• Create pool following documentation in wiki
• Create file/folder on pool
• Attempt to delete
• Windows will inform you, "You need administrator permission to perform this action."
• Remove-Item commands will return "Access denied."

All ACL settings are at their default settings: aclmode=discard, acltype=nfsv4, aclmode=restricted
The issue persists with ACL as follows: aclmode=discard, acltype=off, aclmode=discard

This issue does not occur whatsoever on 2.3.1rc14 - I can create and delete files with no permissions issues on this version.

defaults for a "Windows alike" behaviour should be

zfs get acltype,aclmode,aclinherit winpool/2
NAME       PROPERTY    VALUE          SOURCE
winpool/2  acltype     nfsv4          default
winpool/2  aclmode     passthrough    inherited from winpool
winpool/2  aclinherit  passthrough    inherited from winpool

but even then I must confirm administrator and
when I copy a file from ntfs to zfs, I get "file does not exists)

file already exist, replace?

Hello @furistar, I have the same problem: #470 (comment)

As described there I can delete files if they are in subdirectories. But this only applies to a newly created pool. For my existing pool all files need admin rights for deletion - even in subdirectories.

In my case, with version 2.4.1rc10, I am unable to delete files/folders without admin privileges regardless of directory depth. The pool was created on the latest version, 2.4.1rc10.

Thank you @lundman

I just tested 2.4.1 RC 11b and the deletion of file/folders now works as expected.

If I delete a file in File Explorer by putting it in the Recycle Bin first then delete it there, it seems to work, but if I export then import the pool again, the file in the Recycle Bin goes back. Also, if I delete a file directly by using the del command in Command Prompt, it seems to work, but the file goes back without security permissions, making it not deleteable or accessible until I export and import the pool again, which fixes the security permissions. Is this the case for you too?

Well, you're right. I spoke too soon. After a remount or reboot the deleted items are back in the recycle bin.

I also can reproduce this behavior.
