When running "pvs" on the broken system, no RAID volumes were listed, only component devices.... After updating, look at the output of "pvs" if you use LVM on software RAID.

What exactly did `pvs' show and instead of what?

It should print:

# pvs   PV         VG          Fmt  Attr PSize   PFree   /dev/md127 VolGroup    lvm2 a--   <2.73t <768.41g   /dev/md2   BackupGroup lvm2 a--   <2.73t       0   /dev/sdd1  VolGroup    lvm2 a--  <55.88g       0

and IIRC, it printed:

# pvs   PV         VG          Fmt  Attr PSize   PFree   /dev/sda3 VolGroup    lvm2 a--   <2.73t <768.41g   /dev/sdc1   BackupGroup lvm2 a--   <2.73t       0
