Do you see any error messages on console ?

This looks like the SD card is read-only. Some cards do that when
weared out, but I would expect they report at least a write error.

The filesystem ignores write errors. Before umount, you still see
the buffered data, but after remount the data is gone as it has
never been written successfully.
