So I've been reading and studying for a few weeks, run xubuntu off a usb, getting ready for my 1st linux install - bootable raid1.
I have read about setting up partitions for /swap, /user, /opt etc.
I understand the benefit of LVM is scaleable Logical Volumes and can add and remove LV's.
reading this guide:
Looking at first diagram or the diagram at Wikipedia:
The Logical Volume Group spans the entire HDD and LVs (can we call those virtual partitions?) are contained in the Vol Group.
If I create an LV to mount /swap,
and an LV to mount /opt
and an LV to mount /user etc
What does partitioning my physical 500GB HDD gain me (for a bootable RAID1) before I install the LVM and Vol Group on top of the HDD?
Doesn't the OS only see the LV's in the Logical Group?
Wish I could cut and paste a template for bootable RAID1 hdd LVM/partition setup from someplace...
