identifying a unique minor number for volume group
Hi guys,
I am creating a new volume group and have not done so for ages. I am at the mknod stage however can someone tell me how to check what minor numbers have already been used. The reason for my query is our volume groups are not simply numbered, they are actually given names i.e. vgABCData
We already have 14 volume groups so I would assume minor numbers 0 - 13 have been used. But obviously I want to be sure before I do anything.

Check al the group files
ls -l /dev/vg*/group
Now you can see al the minor numbers that are in use.
ls -l /dev/vg*/group

I tried that already but for some reason it did not work.
But the following did work:
ll vg* | grep group
