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:
python-lvm calls generate message lvmetad[861]: WARNING: Ignoring unsupported value for cmd.
Version-Release number of selected component (if applicable):
kernel-3.10.0-1062.7.1.el7.x86_64
lvm2-2.02.185-2.el7_7.2.x86_64
lvm2-libs-2.02.185-2.el7_7.2.x86_64
lvm2-python-libs-2.02.185-2.el7_7.2.x86_64
How reproducible:
every time
Steps to Reproduce:
#!/usr/bin/python
import lvm
print(lvm.listVgNames())
Actual results:
Dec 12 09:07:27 localhost.localdomain lvmetad[861]: WARNING: Ignoring unsupported value for cmd.
Dec 12 09:07:27 localhost.localdomain lvmetad[861]: WARNING: Ignoring unsupported value for cmd.
Expected results:
No warning, or suppressed warning
Deems issue is access as root is needed
[loberman@rhel7lobe Downloads]$ ./lv_test.py
/run/lvm/lvmetad.socket: access failed: Permission denied
WARNING: Failed to connect to lvmetad. Falling back to device scanning.
()
[loberman@rhel7lobe Downloads]$ sudo ./lv_test.py
('rhelnew',)
cmd is not set by python library. This is harmless, as lvmetad is using this only in debug strings. Also there is pid field to identify process more precisely, but for humans the actual command would be more helpful. Definitely not worth a blocker.
