** I note that the file system on /dev/sdc2 is 'Linux' and not 'Linux LVM'. This is what I got, eventhough I created it with parted /dev/sdc mkpart ...
There's your problem I think. In my first post, I *guessed* that type needed to be 86. I'm sure 83 is NG - that's a standard Linux part. With fdisk and it's variations, there is a command to change partition type. Do that and select the one that shows LVM 986 I think). Write and (possibly) reboot or sfdisk -R /dev/sdc (which re-reads the partition info. If it shows *LVM* as the type, do you pvcreate, vgcreate, etc. and I bet you are OK.
Had to wait until I came back to work and could reboot the machine. Using William's instructions, modulus using 8e as Matt Hyclak pointed out, seems to solve the problem. Everything seems to work fine: lvcreation, writing files, etc.
The only odd thing is in regard to the output of sfdisk. Note the warning when 'sfdisk -l' is invoked without a device argument. According to the man page this is a legitimate call that should produce output similar in nature to 'fdisk -l' (which works as expected).
<man> The second type of invocation: sfdisk -l [options] device will list the partitions on this device. If the device argument is omitted, the partitions on all hard disks are listed. % sfdisk -l /dev/hdc </man>
Since programmers are notorious for putting off the documentation, it is very common to have man pages not completely in sync with a program.
