With some help I found a simpler method to reproduce this: . set multipath.conf no_path_retry fail (in my case it needed to go in overrides section) . create mpath dev over single scsi dev . create PV on the mpath dev . echo offline into sysfs state for scsi dev . lvm fails to read the mpath dev in a way that reproduces the bug Marking Verified:Tested in the latest rpms. kernel-5.14.0-58.el9 BUILT: Thu Feb 10 11:18:21 AM CST 2022 lvm2-2.03.14-4.el9 BUILT: Wed Feb 16 06:01:21 AM CST 2022 lvm2-libs-2.03.14-4.el9 BUILT: Wed Feb 16 06:01:21 AM CST 2022 lvm2-dbusd-2.03.14-4.el9 BUILT: Wed Feb 16 07:23:08 AM CST 2022 SCENARIO - pvs_scanning_of_offline_mpath_device: Test that LVM is able to scan PVs using offline mpath devices and not alter their PVIDs (bug 2052355) WARNING: This scenario will end up repartitioning your device! adding entry to the devices file for /dev/sdc1 removing entry from the devices file for /dev/sdc1 multipath /dev/sdc adding entry to the devices file for /dev/mapper/mpatha1 creating PV on hayes-02 using device /dev/mapper/mpatha1 pvcreate --yes -ff /dev/mapper/mpatha1 Physical volume "/dev/mapper/mpatha1" successfully created.
