I haven't done much with LVM in years - my manager doesn't care for it, we
use a fair bit of RAID, but...

This looks like a clue to me - I wonder if sdg is failing, or has failed.

Do you have a current snapshot? I *think* you're going to have to quiesce

lshw or smartctl to find the s/n of each, before you pull the drive.

Hope that helps.
