Does it mean that doing rerun on current md_0_1.trr file is impossible, unless it is transfered to a cluster or a more powerful system?

It seems like your file system cannot handle files over 2gb even for splitting, which is not surprising, because the limitation is based on the use of a 32-bit integer. You should get access to a better file system, where maybe your file can be read.
