Logical Volume Manager (LVM) does not activate a
free physical volume when one of the NVMe devices is
surprise removed
Description: When one of the members of a RAID 1 LVM array is surprise removed, the LVM does not replace the
removed device with a free physical volume (PV) that is available in the volume group.
Applies to:
SUSE Linux Enterprise Server 15 Service Pack 2
Cause: The issue is related to the handling of failover logic in the LVM.
Workaround: The command lvconvert --repair can be used to add the free PV to the RAID 1 LVM array.
Solution: The issue is resolved in the Maintanance Update lvm2 version lvm2-2.03.05-8.6.1. For more information,
see SUSE Linux Enterprise Server Knowledge Base article 19717.
