Using "g.region -d" should be sufficient.

When reporting problems to the list, it helps if you can perform tests
This will disable the use of translated messages.
In this case, the above is probably this:
G_warning(_("map [%s] - unable to write row %d"), fcb->name, row);
from write_error() in lib/gis/put_row.c.
This error normally arises from exceeding some limit, either:
1. The 2GiB limit on a file, if GRASS was compiled without large file
2. Exceeding your account's disk quota.
3. Running out of space on the partition (note that Linux normally
reserves 5% of the disk space for root).
If either 2 or 3 occurred, that could explain the corruption with the
WIND file: the program tries to modify it but there is no space
available to write the updated WIND file.
Unfortunately, it isn't straightforward to handle this situation
gracefully. You just have to ensure that you don't run out of disk
