      What filesystem do you have? Could it be XFS?

        If XFS the command syntax is...

        xfs_growfs /mount/point -D size

          It's XenServer, we are expecting EXT4 here, right?

              Is this improper syntax?

                Try +3.91.

                Also, why not have the data on its own volume? It's more flexible that way.

                  If the +doesn't work you will have to add it to the existing size. So if its 5TB it would be 8.91

                    Just appears that the size is too small.

                      @scottalanmiller That confuses me because each is 1.9T

                        Why? Your total from your LVS command looks like 3.89TB but you are trying to expand to 3.91TB.

                          @scottalanmiller LVS is 3.89T

                            I edited while you were typing. I read the wrong field. But it is still too small. The FS must be smaller than the container holding it.

                              How much smaller? even 3.86 kicks back the same error

                                Try something like 3.4TB. Remember FS overhead.

                                    Does the + reflect the entire size or just the amount of growth?

                                      -D goes to total. Do the command instead with the -d option and no number...

                                      xfs_growfs /dev/mapper/centos-root -d

                                          Well, the capital D made us have to know the size. The lower case d calculated it for us. The upper case one would have been fine had the number we gave been the right one. But that's just a pain.

                                            I'm unsure why it was considered wrong. I tried a much much smaller size and it didnt work either
