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.

Description John Pittman 2018-12-27 19:33:48 UTC
Description of problem:

When using 'udisksadm dump', if the user reaches the bottom of the output, they can not scroll back up.  The only way to move forward is ctrl-c or kill the pid.

Version-Release number of selected component (if applicable):

libudisks2-2.8.0-2.el8.x86_64
udisks2-2.8.0-2.el8.x86_64

Steps to Reproduce:
- Run command 'udisksctl dump'
- Page down to the bottom of the output
- Attempt to page back up


Actual results:

The user can not page back up once the bottom of the output is reached; only ctrl-c out.  If the bottom is not reached, the user can scroll back up.

Expected results:

User should be able to scroll as needed.  It seems results would be better if output scrolling functioned like 'less' command.

Confirming, reproducible on different systems.

Comment 3 xhe@redhat.com 2019-01-04 06:15:47 UTC
Hi Tomas,

Do you know there are any automation ways to check this issue? I don't know how to check the scroll of screen with code.

Hmm, you may set the PAGER env. var. to something else than `less` and observe that udisksctl left the stdout open. I'm not aware of any nice and easy solution right away. Perhaps a simple python script acting like a page could do the trick (just an idea).
