Read the description of this:

man resize2fs

Note especially this paragraph:

The resize2fs program does not manipulate the size of partitions. If you wish to enlarge a filesystem, you must make sure you can expand the size
of the underlying partition first. This can be done using fdisk(8) by deleting the partition and recreating it with a larger size or using lvex‐
tend(8), if you're using the logical volume manager lvm(8). When recreating the partition, make sure you create it with the same starting disk
cylinder as before! Otherwise, the resize operation will certainly not work, and you may lose your entire filesystem. After running fdisk(8), run
resize2fs to resize the ext2 filesystem to use all of the space in the newly enlarged partition

And make a backup before!
