[brian_31]

this is the error i get when i extend thru SAM

The command used to extend logical volumes, /sbin/lvextend, has
failed. The stderr output from the command is shown below. The
logical volume has not been extended.

vgcfgbackup: /etc/lvmtab is out of date with the running
kernel:Kernel indicates 12 disks for "/dev/data1"; /etc/lvmtab has
11 disks.
Cannot proceed with backup.

check that you didn't miss disks.

vgdisplay -v /dev/data1

mv /etc/lvmtab /tmp/lvmtab.old

vgscan -av

and see if it can rebuild lvmtab.

It looks like you need to take of ghost disk for data1 volume group using lvreduce -m 0 -k /dev/data1/lvol ...

Hello brian
check vgdisplay -v should show new disk.if its ok check pvdisplay -v of that specific disk ,it should not show any extent as stale.
