The most likely reasons are:

1. Your version of GRASS was built without LFS (large file support),
and the cell/fcell file reached the 2GiB limit.

2. The disk is full or you exceeded your quota.

If you're building GRASS yourself, be sure to use the
--enable-largefile option when running configure.
