why is the resizing failing
 

Do you know why this will not resize from 2.7TB to 10TB I just added to sdb.?

This didn't work either.

[root@nmt01 ~]# lvextend -r -L +10G /dev/mapper/centos-opt_zl_nwi_var

You have mail in /var/spool/mail/root

The resize2fs is for ext3 and ext4 filesystems only.
Check your file system type

its a xfs filesystem.

so I thought lvextend would work. but its telling me I don't have insufficient free space. it shows the new space when I do a lvs - shows 12.65t

[root@nmt01 ~]# lvs

opt_zl centos -wi-ao---- 800.00g

root centos -wi-ao---- 450.00g
swap centos -wi-ao---- 128.00g

For XFS, try xfs_growfs instead of resize2fs

wow this is crazy... shows xfs is not mounted but it shows it here.

[root@nmt01 ~]# xfs_growfs /dev/centos-opt_zl_nwi_var

shows xfs.

Please try xfs_growfs on the mount point, so

[root@nmt01 ~]# xfs_growfs /dev/mapper/centos-opt_zl_nwi_va
xfs_growfs: /dev/mapper/centos-opt_zl_nwi_va is not a mounted XFS filesystem
