1 Hi,
2
3
4 I've created a raid-5 (md0) with 3 hdds and chunk size=512KB.
5
6 On top of it, using the default options, I've created a lvm2 physical
7 disk with one volume group. "vgdisplay" shows PE=4MB.
8
9 Now I have several logical volumes in this group which have to be
10 formatted with ext3.
11
12 Here comes my question.
13 How do "stride" and "stripe-width" options of mke2fs relate to
14 "chunk-size" of mdadm and PE of LVM2? What values should I use and why?
