Hi.
I've added a new (faster) disk to a VG and now want to move a thinly
provisioned LV to the new PV. When I try it doesn't find any data to
move though:
# pvmove -n /dev/rootvol_tmp/var /dev/sda7 /dev/sdc
No data to move for rootvol_tmp.
both disks are in the VG though:
Hi
lvm2 cannot move 'individual' thin volume as this volume is 'just virtual' and
uses chunks from the thin-pool.
So if you want use thinLV from a new faster storage - then whole thin-pool
must be moved to the faster storage.
And when you will be doing this - move the also _tmeta volume.
(See 'lvs -a' output for volumes you can move)
