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 2023-01-24 20:20:27 UTC 
Description of problem:
This scenario is a regression check failure for bug 1320735. 
Basically, rename the volumes while mounted, and attempt to resize the initially named first volume and see what happens. Per bug 1320735, it should be determined that LVM is attempting to resize a mounted filesystem that is using a device that is referencing a new device now, and that the filesystem needs to be unmounted in order to continue with a resize attempt. The new/current 9.2 behavior is that LVM does the resize of the LV, but then trips up on the fsadm resize.

Comment 1 Corey Marthaler 2023-01-24 20:39:11 UTC 
The same scenario, but with a reduce, prompts that the filesystem needs to be unmounted and then does just that.

Comment 4 David Teigland 2023-02-13 21:36:18 UTC 
I'm not able to reproduce this when I build the lvm2.git rhel-9.2.0, so I wonder if there's a problem with the build, or if there's some difference in the config settings I'm using?

Comment 5 David Teigland 2023-02-13 22:27:22 UTC 
I get the same failure when using the rhel build, so rhel is probably using some build options that I'm not using that trigger the problem.

The segfault is appearing at a buggy strncpy which is already fixed on main with commit:

cf0dc9a13cf3 filesystem: use PATH_MAX for linux paths

I'm guessing that fixes the problem, but unless I can reproduce the problem with some new build options I won't be able to verify it.
Comment 7 Corey Marthaler 2023-02-15 20:04:44 UTC 
The scratch build fixes this new issue.
