[Linux-cluster] pvmove with CLVM messages

[Johnson, Eric]

Hi Gary,

Once the new SAN LUNs were presented to us, I just marked them as
physical volumes, extended the VG, then pvmove'd the old PVs to the new
ones. We had 3 existing LUNs that were moving to 1 larger LUN on the new
SAN.

pvcreate /dev/mapper/mpath4
vgextend datavg /dev/mapper/mpath4
pvmove -b /dev/mapper/mpath1 /dev/mapper/mpath4
pvmove -i 2  (to watch the progress)
pvmove -b /dev/mapper/mpath2 /dev/mapper/mpath4
pvmove -i 2  (to watch the progress)
pvmove -b /dev/mapper/mpath3 /dev/mapper/mpath4
pvmove -i 2  (to watch the progress)
lvdisplay -m /dev/datavg/* | grep "Physical volume"  (only mpath4 shows)
vgreduce datavg /dev/mapper/mpath1 /dev/mapper/mpath2 /dev/mapper/mpath3
pvremove /dev/mapper/mpath1 /dev/mapper/mpath2 /dev/mapper/mpath3

The only difference with the clustered systems was that the cmirror
package needed to be installed and the clogd daemon running.

Eric
