I'm really new to Linux, the question makes me struggle for half a day may be super easy, But I just can't fix it so far. Anyway, here is the problem:
I'm using a cloud-based Linux server:
Linux seller-huge.novalocal 3.10.0-862.11.6.el7.x86_64 #1 SMP Tue Aug 14 21:49:04 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux.

I use this to do data scraping, it worked well it the past, but all my python3 scripts break down today with the following error:

Traceback (most recent call last):
 File "feedback_1.py", line 82, in main
 scrape_wr.writerow(result_scrape)
OSError: [Errno 28] No space left on device

During handling of the above exception, another exception occurred:

OSError: [Errno 28] No space left on device

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
 File "feedback_1.py", line 85, in <module>
 main(0, 200000, 0)

I thought this should be caused by unavailable disk space, So I searched online and figured how to mount new volumes to my instance:

[gaojia@seller-huge feedback_scrape]$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/vda1 20G 20G 20K 100% /
devtmpfs 32G 0 32G 0% /dev
tmpfs 32G 0 32G 0% /dev/shm
tmpfs 32G 33M 32G 1% /run
tmpfs 32G 0 32G 0% /sys/fs/cgroup
tmpfs 6.3G 0 6.3G 0% /run/user/1000
/dev/vdc 197G 61M 187G 1% /myspace3
/dev/vdb 50G 53M 47G 1% /myspace2

vdc and vdb are newly added volumes, judging on the result of df-h, I think they are mounted correctly, but how could I use them then? I mean how could I put data into these volumes?

By saying "put data into these volumes" I am guessing you just want your script to write data to these newly added disks. In that case, you'd need to edit your script to point the destination directory to the mount points to which these disks are mounted on. From the output of 'df -h', /dev/vdc is mounted on /myspace3 and /dev/vdb is mounted on /myspace2.

/myspace2,3 are just like any other directory on your linux filesystem.

$ cp something.txt /myspace3

will copy 'something.txt' file in '/myspace3' directory; and

cp something1.txt /myspace2

will copy 'something1.txt' in /myspace2 directory.

You can write data to those volumes at /myspace2 and /myspace3 as normal.

The issue is that /dev/vda, which is mounted at / and contains the operating system itself, is completely full.

You need to clear space off of / first or else you're going to have a ton of problems which includes updates and installing and running software which will need to write to it.
