Ive found some notes online which indicate that extension of stiped logical volumes can be achieved by adding additional striped columns.

However, what Im really after is the ability to increase the existing stripe width online. I dont really want to go down the backup, recreate new lv and restore method.

I beleive this can be done on VxVM.

Can anyone confirm if this is possible, and if not wether there are plans to add this functionality ?

Cheers in advance

I'm not sure if I totally understand what you're trying to do. Do you have a striped vg, say across 4 disks and you want to add a 5th disk and then stipe evenly accross them? If so, we've had good luck using the reorgvg command. This command reallocates the PPs within the vg so that they are evenly spread across the 5 disks. Take a look at reorgvg and see if it meets your needs.

Hi, i think that your talking about "poor man striping", which is applicable for use with 'reorgvg', rather than a striped logical volume.

But yes, im trying to see if i can increase a stripe width, by adding additional physical volumes. The additional stripe columns does allow me to extend the striped logical volume, but it needs to be extended across another set of disks. eg striped LV sits on 3 disks. To extend the width, i need to provide a further 3 disks to introduce a 2nd stripe column, and extend the LV onto that.

I really just want to be able to reorg the striped logical volume, if I add an additional single PV.
