Red Hat Bugzilla – Bug 978431
ksysguardd won't allow hierarchically automounted filesystems to expire
Last modified: 2014-02-05 16:58:33 EST
Description of problem:
I am using bubblemon to monitor cpu usage. Also using autofs to mount/umount filesystems automatically.
Some autofs configurations cause automount to fail umounting filesystems, mainly hierachical ( nested ) filesystems. For instance, this entry in auto.misc:
stor -rw,soft,intr,nodev,nosuid stor:/archive
mounts stor:/archive at /misc/stor, and unmounts correctly when expired, but this other one:
stor -rw,soft,intr,nodev,nosuid /archive stor:/archive
mounts stor:/archive at /misc/stor/archive but never unmounts when expired, and automount reports the following:
automount: 1 remaining in /misc
This is my configuration for autofs:
# cat /etc/sysconfig/autofs | grep -v "#"
The sampling rate (SR) for bubblemon is 1000 ms, and:
# cat /etc/ksysguarddrc | grep Sensors | grep -v "#"
If SR is set > TIMEOUT or DiskStat is removed from Sensors in ksysguarddrc everything works fine. But if it works for the first automount configuration form defaults it should work for the second automount configuration.
Version-Release number of selected component (if applicable):
# rpm -qa | grep ksysguard | sort
Steps to Reproduce:
1. Load bubblemon into systray and configure a hierarchical mount in autofs
2. Trigger mount of filesystem
3. Watch filesystem fail to expire
Filesystem with a hierachical configuration never expires
It should expire and umount
Can you please report this issue directly to the upstream KDE developers at https://bugs.kde.org/ ? They are more likely to be able to do something about this than we are.
This message is a reminder that Fedora 18 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 18. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '18'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 18's end of life.
Thank you for reporting this issue and we are sorry that we may not be
able to fix it before Fedora 18 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged change the 'version' to a later Fedora
version prior to Fedora 18's end of life.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 18 changed to end-of-life (EOL) status on 2014-01-14. Fedora 18 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
Thank you for reporting this bug and we are sorry it could not be fixed.
