[linux-lvm] Forcing the lvconvert copy to be on a different physical disk



Hi all,

in my company they want to use LVM to handle a transition period while moving VM guests from local datastore to a NAS (via iSCSI)

An example with numbers is worth thousands of words.
The idea is to have one leg locally and one leg on the NAS, then we'll remove the local leg and tha machine will run with the leg on the NAS.

So there are two MBR-partitioned vdisks, 10G each, and with one big LVM partition (0x8e)

I have created one VG spanning both disks and one LV hosted on the local disk.

How to tell lvconvert that the mirror, of the LV I want, must entirely be hosted on the second disk?

Thanks,

Alex
