LVM2 volume group in partial mode with physical volumes marked missing even though they are available in RHEL

Issue

• Couldn't find device with uuid aaaaaa-aaaa-aaaa-aaaa-aaaa-aaaa-aaaaaa and There are 1 physical volumes missing messages in LVM commands even when the PV for the mentioned UUID is seen available.

• Attempting to modify a volume group or logical volume fails due to missing devices that are not actually missing:

  # lvextend -l+100%PVS /dev/myvg/lv02 /dev/mapper/mpath80
    WARNING: Inconsistent metadata found for VG myvg - updating to use version 89
    Missing device /dev/mapper/mpath73 reappeared, updating metadata for VG myvg to version 89.
    Device still marked missing because of alocated data on it, remove volumes and consider vgreduce --removemissing.
  

• Any attempt to change a VG or LV claims PVs are missing:

    Cannot change VG myvg while PVs are missing.
    Consider vgreduce --removemissing.
  

• LVM physical volumes are marked with the missing (m) flag in pvs output even though they are healthy and available:

  # pvs
    PV          VG            Fmt  Attr PSize    PFree   DevSize
    /dev/dev_a  vg_name       lvm2 a--  1019.75g  30.88g 1019.75g
    /dev/dev_b  vg_name       lvm2 a-m   299.92g 189.92g  299.92g <===
  

• Volume group is marked as 'partial' and causes lvm commands to fail:

    VG      #PV #LV #SN Attr   VSize VFree  
    myvg     42  10   0 wz-pn- 2.31T 777.11G
