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:
Specifying partition device by name causes lookup failure, even though
udevadm info reports on the device using export-db
Version-Release number of selected component (if applicable):
[root@megadeth pydevDAG]# udevadm --version
219
How reproducible:
Always.
Steps to Reproduce:
1.
[mulhern-journal@megadeth pydevDAG]$ udevadm info --export-db | grep sde1
P: /devices/pci0000:00/0000:00:01.0/0000:09:00.0/host0/port-0:0/expander-0:0/port-0:0:3/end_device-0:0:3/target0:0:2/0:0:2:0/block/sde/sde1
N: sde1
E: DEVNAME=/dev/sde1
E: DEVPATH=/devices/pci0000:00/0000:00:01.0/0000:09:00.0/host0/port-0:0/expander-0:0/port-0:0:3/end_device-0:0:3/target0:0:2/0:0:2:0/block/sde/sde1
sde1 in database, clearly.
2.
[mulhern-journal@megadeth pydevDAG]$ udevadm info /dev/sde1
Unknown device, --name=, --path=, or absolute path in /dev/ or /sys expected.
[mulhern-journal@megadeth pydevDAG]$ udevadm info -name=sde1
device node not found
3.
[mulhern-journal@megadeth pydevDAG]$ ls /dev/sde1
/dev/sde1
udevadm info /sys/devices/pci0000:00/0000:00:01.0/0000:09:00.0/host0/port-0:0/expander-0:0/port-0:0:3/end_device-0:0:3/target0:0:2/0:0:2:0/block/sde/sde1
works
Actual results:
Partition device not found when specified by name or device node although available in database.
Expected results:
All ways of specifying the device should work.
Additional info:
This may have to do with the fact that the partition device seems somewhat to be a character device: see bz#1319853.
Comment #2: It became a character device when I rebooted, without any action on my part. The reason is still unknown: bz#1319819.
