SUMMARY
Hello! The KDE Plasma System Monitor application does not have any support for
ZFS. I would like to request implementation of support.
There are two issues as a result of no ZFS support.
First, System Monitor cannot and does not report the total storage used in the
system. In the attached screenshot, note the "Disks" widget does not report
anything but the total size of the disk. Other components of KDE like ex. the
file manager are able to accurately report the amount of space remaining,
however, so this seems like just an issue with System Monitor not handing ZFS.
(while a total amount of remaining storage would be good enough, it *would* be
cool if System Monitor could produce `zpool list` / `zfs list` inspired
output...)
Second, System Monitor is unaware of ZFS's usage of available RAM for caching.
I'm not sure of the details here, but I think that there is likely some more
accurate reporting that could be done were it ZFS-aware? I suppose if ZFS ram
caching is reported as "Cache Memory" then it's fine, but I haven't verified
that it is.
STEPS TO REPRODUCE
1. Install KDE on an operating system with a ZFS root.
2. Open System Monitor.
SOFTWARE/OS VERSIONS
Linux: Arch Linux 6.12.51-1-lts
KDE Plasma Version: 6.4.5
KDE Frameworks Version: 6.18.0
Qt Version: 6.9.2
ADDITIONAL INFORMATION
Searching the tracker, there are several related bugs.
- #433804 (zfs support in ksysguard / system monitor widgets)
- #420018 (Hard Disk Space Widget/Plasmoid cannot show ZFS datasets)
- #504733 (Disk usage broken on striped ZFS root)
This is pretty much a duplicate of #433804. It's filed under an unmaintained
component however, so I'm opening a new one here (and suggest #433804 should be
closed).
