Not really.

Somehow your PV is defined to be bigger than the disk it is currently on.
Ways this can happen include the /dev/sdc partition table getting changed
incorrectly, deliberately overriding the device size when creating it,
restoring from metadata backups incorrectly or using 'dd' to copy device
metadata.

You need to start by reviewing your /dev/sdc partition table and making
sure all space on there is accounted for in partitions in the way you
expect: How big is sdc? Where and how big are sdc1 and sdc2?  Is there
any space on the disk not included in sdc1/2/3 ?
