Bug ID: 504660
Summary: Dolphin refuses copy due to space, fails to consider
reflink copies
Classification: Applications
Product: dolphin
Version First 25.04.1
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: general
Assignee: dolphin-bugs-n...@kde.org
Reporter: f...@fellr.net
CC: kfm-de...@kde.org
Target Milestone: ---
SUMMARY
When attempting to copy a directory that is larger than the remaining space on
the device, Dolphin refuses the copy operation after examining the directory
with the message "There is not enough space on the disk to write ..."
While *technically* correct, this does not apply to filesystems that support
reflinks, such as XFS in this case.
STEPS TO REPRODUCE
1. Obtain a XFS filesystem. (May also apply to: bcachefs, btrfs, possibly ZFS
and network file systems as well)
2. Create a directory (or file) to occupy more than half of the available
space.
3. Attempt copy it within the same filesystem.
OBSERVED RESULT
Dolphin refuses to copy, shows message: "There is not enough space on the disk
to write ..."
EXPECTED RESULT
Dolphin recognises that a reflink copy can be performed and continues to do so.
Just like the `cp` command would.

ADDITIONAL INFORMATION
This *may* be actually a KIO issue, but I also tested Krusader and it does not
seem to be affected. Therefore I'm filing this as a Dolphin bug.
