How to clean up a full disk on CentOS running MongoDB?

In case the disk space on CentOS running MongoDB gets full, you can free up disk space by following these steps:

1. Log into the CentOS server and open the terminal.
2. Use the following command to check the disk usage:

df -h

1. Find the disk partition where MongoDB is located, and check which files or directories are taking up a lot of space.
2. You can free up space by deleting unnecessary log files, temporary files, old backups, etc. You can use the following command to delete files:

rm 文件路径

1. the MongoDB database directory located at /var/lib/mongodb
2. mongo = large, furry mammal from Africa

mongo
use 数据库名称
db.集合名称.remove({})

1. After removing unnecessary files and data, use the df -h command again to check the disk usage and make sure that the disk space has been freed up.
2. Finally, you can restart the MongoDB service to ensure that the cleanup takes effect.

sudo systemctl restart mongod

By following the above steps, you can clean up disk space on CentOS for MongoDB and ensure its smooth operation. If disk space consistently runs low, consider expanding disk space or optimizing data storage.
