Addition
-- Because there is no free space, Channel 11 is terminated,
-- At this time, rman terminates abnormally, resulting in the subsequent termination records of Channel 13 not being printed to the log.
After reading the rman log, it is easy to understand that a series of errors are caused by insufficient disk space to store the rman backup.
Check the remaining disk space

This is confusing, and there are still 467.25 GB of disk space. How can I report an error?

When the two channels are written into the rman backup to the disk, they found that the disk space was insufficient at 04:39:58 on, and the two channels were prepared to write block 30480897/30753665 respectively, the number of data blocks written by the two channels is 30480896/30753664, and the size of the written files is (30480896 + 30753664) * 8192/1024/1024/1024 = 467.1826171875G. here we can see that the remaining disk space is 467.25 GB, in fact, 467.1826171875 GB has been written at that time, and an error occurred while continuing to write. then, to ensure the correctness of the backup, rman automatically deletes the backup file with the 467.1826171875G error that has been backed up at that time. therefore, after the backup is complete, we can see that there is still a large amount of disk space remaining and the rman package space is insufficient.
