Note: This bug is displayed in read-only format because
the product is no longer active in Red Hat Bugzilla.
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.

Looks like there were some changes between RHEL7 and 8 in the way partition is traced.
Dwight, could describe your reproducer in more details as Eric mentioned? I wasn't able to get the trace you provided with just a lvm partition on top of two partitions.
We're going to need some help from the reporter if we wish to continue to pursue this one.

I see this in customer blktrace data submitted. I don't have a reproducer (my laptop with a single nvme ain't going to cut it).
remap events are expected to look like the following: dm-1 -> sdb1 -> sdb
8,17 7 1 0.000000000 73033 A WM 33939951648 + 32 <- (253,1) 33939949600
8,16 7 1 0.000000000 73033 A WM 34939951648 + 32 <- (8,17) 33939951648
but in customer blktrace data often has: dm-1 -> sdb, sdb1->sdb
8,16 7 1 0.000000000 73033 A WM 33939951648 + 32 <- (253,1) 33939949600 << this should have target of 8,17 not 8,16
8,16 7 1 0.000000000 73033 A WM 34939951648 + 32 <- (8,17) 33939951648 << which means matching above needs tricks.
