RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

How reproducible:


Steps to Reproduce:

Setup
   1. Obtain an USB mass storage device.
   2. Plugin in USB device.
   3. Let OS mount USB device (lets say that USB mass storage corresponds with /dev/sdb1).

Actions:
   1. Open terminal
   2. Runas root

      udisks --detach /dev/sdb1

  
Actual results:

Detach failed: Device is not a drive

Expected results:

The USB device should be unmounted and powered down.

Comment 3 Bill Nottingham 2010-05-13 14:44:12 UTC 
What happens if you do udisks --detach /dev/sdb (specifying no partition?)
Comment 4 David Zeuthen 2010-05-13 17:22:02 UTC 
As Bill says you are using the command incorrectly. If you use /dev/sdb it should work. Btw, you also need to ensure that all partitions etc. are not in use (e.g. not mounted, not claimed by LVM, MD etc.) otherwise the command will fail.
