"Cause of error"

Rman error message when generating backup set files encountered problems, file I/O errors, so it is suspected that the backup is full of space, so look at the backup path space, found that there is not enough space to create a backup set file.

"Workaround"

Delete the unused/outdated backup set, free up space, and then execute the backup command again.
