Re: Resizing underlying LVM partition after cloning to bigger disk

I did consider that as an easier option.

Based on what is said here: http://tldp.org/HOWTO/LVM-HOWTO/multpartitions.html if I don't have striped logical volumes and there's only one physical drive, can I expect any performance issues?

Why don't you just make a new partition and add it to the VG, then expand the LV. Isn't that the point of LVM?

You are getting to a size where msdos partition tables are risky.
Don't they crap out at 2TB?
