https://bugzilla.novell.com/show_bug.cgi?id=306288 Summary: device mapper grabs my USB disk and prevents mounting it Product: openSUSE 10.3 Version: Beta 2 Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: seife@novell.com QAContact: qa@suse.de CC: dkukawka@novell.com Found By: Component Test In my past-Beta2 system, after plugging in my USB drive, it cannot be mounted by the KDE mediamanager and by halmount ("device is busy"). During investigation of this issue i found out, that devicemapper grabs the device and subsequently it can no longer be used. root@strolchi:~# l /dev/mapper/* lrwxrwxrwx 1 root root 16 30.
