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 of problem:
udisksd: Error creating watch for file /sys/devices/virtual/block/md126/md/sync_action: No such file or directory (g-file-error-quark, 4)
udisksd: Error creating watch for file /sys/devices/virtual/block/md126/md/degraded: No such file or directory (g-file-error-quark, 4)
udisksd: Error creating watch for file /sys/devices/virtual/block/md127/md/sync_action: No such file or directory (g-file-error-quark, 4)
udisksd: Error creating watch for file /sys/devices/virtual/block/md127/md/degraded: No such file or directory (g-file-error-quark, 4)
seen during boot.
Version-Release number of selected component (if applicable):
udisks2-2.1.2-6.el7.x86_64
How reproducible:
Steps to Reproduce:
1.
2.
3.
Actual results:
Expected results:
Raid 0 doesn't provide any redundancy, so the kernel won't expose the corresponding redundancy sysfs attributes like sync_action and degraded. So udisks should not try to add watch for these files.
Additional info:
These errors are seen on raid1 too.

Customer followed the below steps to build RSTe RAID1:
1. Select SATA controller to be RAID mode
2. "Save and reboot" for new setting
3. Boot into BIOS setup again
4. Enter Advanced/Intel RSTe SAT controller
5. Select two SSD and build RAID1
6. "Save and reboot" for new setting
7. Install RHEL 7.2 OS

After a talk with vtrefny I am able to reproduce the bug using SW RAID 0 with udisks2-2.1.2-6.el7.x86_64.rpm, but I am not able to reproduce the bug using SW RAID 1.
See my reproducer in TCMS.
The problem (error messages) does not occur with udisks2-2.7.3-3.el7.x86_64, so I could confirm the bug is fixed.
Can customer verify the fix on the hardware RAID?
