[CentOS] possible LVM corruption?

While updating a hypervisor, I'm getting the following errors printed to 
the terminal during rpm upgrade scripts.  The first line is printed 15 
times, and GRUB prints a similar error at boot.  "vgck" doesn't seem to 
find any problems.  Does anyone have suggestions for diagnosing the issue?


error: ../grub-core/disk/diskfilter.c:524:unknown node 
'vm_ipa-data_rimage_0'.
grub2-probe: error: ../grub-core/kern/disk.c:236:disk 
`lvmid/uhx5FA-RmdV-cPYP-ELEA-pUrn-FfHl-M2RBEV/JQKCwn-RhKX-ek4u-VJxX-ja9j-rtAD-fVUBGc' 
not found.
