Bug ID: 496400
Summary: exFAT volume label longer than 10 chars causes error
Classification: Applications
Product: partitionmanager
Version: 24.08.3
Platform: NixOS
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: andr...@stikonas.eu
Reporter: m...@eliasprobst.eu
Target Milestone: ---
SUMMARY
When using a label longer than 10 characters for an exFAT volume,
KPartitionManager fails to apply those changes and the error displayed doesn't
provide any information on why it failed.
STEPS TO REPRODUCE
1. Create an exFAT volume
2. Set the value of "Label" to "LongLongLabel"
3. Apply the changes
OBSERVED RESULT
- KPartitionManager fails to apply the changes.
- The "Details" view of the corresponding job displays:
> Job: Set the file system label on partition ‘/dev/sdb1’ to "LongLongLabel"
> Command: tune.exfat /dev/sdb1 -L LongLongLabel
> Set the file system label on partition ‘/dev/sdb1’ to "LongLongLabel": Error
> Create a new partition (58,94 GiB, exfat) on ‘/dev/sdb’: Error
EXPECTED RESULT
KPartitionManager doesn't allow to set labels on exFAT longer than 10
characters and shows a corresponding validation failure in at least the
following dialogs:
- Right click on volume → Properties
- Right click on unallocated space → New
SOFTWARE/OS VERSIONS
Operating System: NixOS 24.11
KDE Plasma Version: 6.2.3
KDE Frameworks Version: 6.8.0
Qt Version: 6.8.0
Kernel Version: 6.6.60 (64-bit)
Graphics Platform: Wayland
Processors: 4 × Intel® Core™ i5-6200U CPU @ 2.30GHz
Memory: 19.4 GiB of RAM
Graphics Processor: Mesa Intel® HD Graphics 520
ADDITIONAL INFORMATION
When executing "tune.exfat /dev/sdb1 -L LongLongLabel" manually (which is what
the job details show, is also executed by KPartitionManager), it displays a
helpful message:
> exfatprogs version : 1.2.5
> input string is too long
> failed to encode volume label
So another change that probably should be made is, to display the command
output in the "Details" view, since this would have more easily allowed to
figure out what actually went wrong.
