Correct. If there's just accesses to extents mapped onto hdb (i.e. from the filesystem), hdc will never spin up (unless somthing outside LVM triggers it ;-) > But if, it is a good explanation as my volume still has plenty of space > so hdc would not be accessed until hdb is full. See "pvdisplay -v /dev/hd[bc]" or "lvdisplay -v YourLV" for your logical volume(s) to see what is mapped onto what. > -- > Cheers, > > Michael > > _______________________________________________ > linux-lvm mailing list > linux-lvm@sistina.com > http://lists.sistina.com/mailman/listinfo/linux-lvm > read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/ -- Regards, Heinz -- The LVM Guy -- *** Software bugs are stupid.
