Hi, I have an lvol that someone setup that spans over two disks. What they were supposed to do is set it up on one disk and then mirror the lvol to the other disk. Is there a way to move the extents on the mirrored disk to the root disk?
So all extents on c2t0d0s2 be moved to c2t1d0s2 while all filesystems and applications are online? Like with no service interruption?
This is an HP-UX 11.23 server
lvdisplay -v /dev/vg00/lvol16

Re: move extents
Related to http://h30499.www3.hp.com/t5/LVM-and-VxVM/Distribution-of-Logical-Volume/m-p/6024055 ???
Remove the mirror and set up again.
Make sure the second disk is bootable!
Hope this helps!
Regards
Torsten.

Re: move extents
There is no mirror...as you can see from my snippett above, all data is spread over two disks and I want it on one disk and then mirrored to the other.

Re: move extents
Thank you Patrick, yes I found the pvmove command and that is what I will use.
