[Bug 413059] New: cryptsetup loops on /dev/.udev/uevent_seqnum on shutdown
https://bugzilla.novell.com/show_bug.cgi?id=413059 Summary: cryptsetup loops on /dev/.udev/uevent_seqnum on shutdown Product: openSUSE 11.1 Version: Factory Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem AssignedTo: ro@novell.com ReportedBy: jblunck@novell.com QAContact: qa@suse.de CC: fehr@novell.com, kasievers@novell.com Found By: --- During shutdown, cryptsetup remove $name is called to remove the encrypted lvm device. This is waiting for udev to process the event which loops on /dev/.udev/uevent_seqnum to find out if udev has dealed with the event yet. Since udevd gets killed before the /etc/init.d/boot.d/K* scripts are run, this loops forever. A possible solution would be to call the /etc/init.d/boot.d/K* scripts before sending SIGTERM to all running processes. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

This is fixed ...
Nice. Thanks!
nevertheless the job of udevd is more a job of a real kernel thread as IMHO this is a system relevant challenge. This would avoid the problem of killing a user space job ... an other option would be a `plugin' for /sbin/init.
Sounds right, yes. Unrelated to the killing of udevd, I've added the "unlink /dev/.udev/uevent_seqnum" patch, it sounds fine to clean that up on exit. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
