Mac tips
dscacheutil -flushcache
LVM
Initialize the device
pvcreate create a volume, fdisk type 8e
pvcreate /dev/hdb1 can use entire disk if you want
vgcreate my_volume_group /dev/hda1 /dev/hdb1 - put as many disks/partions etc into the group
After rebooting the system or running vgchange -an, you will not be able to access your VGs and LVs. except most systems do this automatically
To reactivate the volume group, run: Only needed to activate on the fly
vgchange -a y my_volume_group
to remove groups Deactivate the volume group: vgchange -a n my_volume_group, then you can remove the volume group: vgremove my_volume_group
