Hello,

I have a physical volume with no volume group.

# /sbin/pvscan -n WARNING: only considering physical volumes in no volume group PV /dev/sdg2 lvm2 [148.95 GB] Total: 1 [148.95 GB] / in use: 0 [0 ] / in no VG: 1 [148.95 GB]

Can I just create a volume group -- for example: # vgcreate my_volume_group /dev/sdg2

Yes, this how you create a _new_ volume group using a _unused_ physical volume. If, as you say below, you have data on this device then this is most likely _not_ what you want. Maybe you should look into vgimport/vgscan/etc.

/Peter

and then activate it:

# vgchange -a y my_volume_group

I don't wish to reformat it or otherwise lose data stored on the volume if possible.

Other suggestions?
