1706984 – "Unknown feature in status:" messages in lvs output

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 Corey Marthaler 2019-05-06 14:35:05 UTC

Description of problem:
I'm not sure what volume type and attribute is exactly causing this yet, but it appears to be thin/thinpool volumes. I've seen this many times in initial rhel7.7 test output.

Comment 3 Evans 2019-05-24 11:05:30 UTC

I am having this issue as well on ArchLinux. I am new to LVM2, so I don't quite understand what causes this to happen.

I'm not sure which one causes the issues, but I have a few in mind:
1. I just updated my kernel (just today), running lvs -a gives the error
2. I have several unclean shutdown

I cannot confirm whethere this issue is present before any of those two.

I then try running

vg/cache_data
vg/root

Comment 4 Zdenek Kabelac 2019-05-24 11:26:49 UTC

kernel started to report new 'keyword' in status - and lvm2 has not yet learned about it.

There will be soon some upstream patch for this new kernel enhancement.

Other then that - you can continue to use lvm2 normally - just command will print this 'unknown' warning.

Comment 5 Marian Csontos 2019-06-20 18:04:39 UTC

Do we want this fixed in 7.7?

Comment 8 Corey Marthaler 2019-10-15 20:16:03 UTC

This appears fixed in the latest 7.8 rpms.
