Why does it say no space available when a lot are avaliable?

I am in my own directory:

/usr/home/cong/data

And in this directory, I am executing a rsync command to copy a 24G file from a remote machine to my home directory on this machine. On the half way of copying, it reports:

rsync: write failed on "/usr/home/cong/data/content_8_days.txt": No space left on device (28)
rsync error: error in file IO (code 11) at receiver.c(393) [receiver=3.1.2]

Is that because my directory is under /usr, which only has 15G avaiable? In such a case, how to make use of other spaces under, i.e. /data1, /data2?

yes

In such a case, how to make use of other spaces under, i.e. /data1, /data2?

Copy the file to one of them.

e.g:

/dev/sda2 30G 13G 15G 47% /usr
