lvm: PE size, number of stripes and stripe size considerations
I intend to set up my future Slackware-13.0 installation with LVM. I have already read the available How-To, but there are are still three parameters that I feel uncertain how to set. These are the size of the physical extents (PE), the number of stripes and the stripe size. The documents I have come upon so far only seem to tell how to set these parameters to certain values, but not WHY these particular values are selected. Are there any rules/reasons to follow with regard to the choice of the these parameters?
Thank you very much for your attention.
