No. You must delete one of the 2 and extend the remaining one. If you don't have enough space to save all the data in the LV that you want to delete, you can manually shrink the filesystem on it, shrink the LV, extend the other LV, extend the filesystem and move data. Then restart shrinking and extending until all the data is moved. -- Flavio Visentin A computer is like an air conditioner, it stops working when you open Windows
