AWS EC2 : Disk Full

[dupdroid]

Good day,

I have run out of disk space.

Is there a way I can free up space via terminal to get my redash up again without having to expand the disk size?

Note: I changed all my query_ to cached_query_ for performance and I think this caused the disk space increase. Using
redash/redash:10.0.0.b50363

Thanx
