Looking at the disk access it appears that I have no stripe. All data access seems to be on the first drive. How do I re-configure the volume group to stripe accross the two physical drives? ^ permalink raw reply [flat|nested] 3+ messages in thread

I think you've to recreate the Logical Volume(s) using the stripes option (-i) http://linux.die.net/man/8/lvcreate -- Giovanni. ^ permalink raw reply [flat|nested] 3+ messages in thread

I assumed that the default was for LVM to stripe and by adding bot disks to the volume group before migrating it of the physical extent I would be OK. I migrations can loose stripe then surely that is an issue? The Volume was created as part of a xen server virtual machine install so I have limited control over initial LV creation parameters.
