Bug ID: 469283
Summary: cannot copy files to smb when accessing a DFS share
Classification: Frameworks and Libraries
Product: kio-extras
Version: 23.04.0
Platform: Gentoo Packages
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Samba
Assignee: plasma-b...@kde.org
Reporter: k...@kaishome.de

Target Milestone: ---
SUMMARY
When accessing a Windows DFS share through kio, dolphin complains about not
enough space in the destination copying data to the share. Running "df" on the
kio mount confirms that there are 0 bytes reported free, and the reported file
system size is also 0 bytes. From cmdline, files can still be created or
copied.
Accessing the same share directly from the DFS member reports correct sizes and
allows dolphin to copy files to the share.
Mounting DFS directly via CIFS kernel support reports the correct values.
SMB shares:
\\domain.local\DFS\Storage -> 0 bytes free and 0 bytes size
\\member1.domain.local\Storage -> sizes reported correctly
\\member2.domain.local\Storage -> also reported correctly
STEPS TO REPRODUCE
1. Setup a DFS share with two member servers and DFSR sync
2. Access share via DFS share via kio to check for free space
3. Access share directly on member server via kio to check for free space
OBSERVED RESULT
kio-smb reports 0 bytes free and 0 bytes file system size, preventing kio
clients from writing data due to out of space condition (actually, it may
complain about insufficient permissions sometimes but that's not true, it's
still "out of space").
EXPECTED RESULT
kio-smb should report file system stats correctly for DFS shares.
