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 Jiří Mencák 2020-07-08 09:51:17 UTC
Description of problem:
While verifying tuned daemon functionality on a two systems I've noticed the [disk] plugin is not able to adjust tuning for some block devices.  In my case these were a DVD-ROM and an NVMe drive.

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

How reproducible:
Always

Actual results:
Unability to use the [disk] plugin to set properties such as IO disk elevator on devices such as NVMe drives.

Expected results:
Review the [disk] plugin and have the ability to use it to set the tuning where it makes sense.

Comment 3 Jaroslav Škarvada 2021-11-02 15:43:37 UTC
I think it's bug. I think it should process nvme by default and probably with the regex in place it shouldn't do any additional filtering.
