How to check VPS capacity is full

To check if your VPS (Virtual Private Server) capacity is full, you can follow these steps:

Step 1: SSH into the VPS

Use an SSH client to connect to your VPS. You’ll need the IP address or domain name of the server and appropriate credentials (username and password or SSH key) to log in.

ssh username@your_server_ip

Step 2: Check Disk Space

Once you’re logged into the VPS, you can use the df command to check the disk space usage. This command displays information about the available and used disk space on your server.

df -h

The -h flag stands for “human-readable,” which formats the output in a more readable format with sizes in KB, MB, GB, etc.

Step 3: Identify Full Partitions

The df command will display a list of partitions along with their usage details. Look for partitions that have a high percentage of use. This could indicate that those partitions are getting full.

Step 4: Check Individual Directory Sizes

Sometimes, a specific directory might be using up a significant portion of the disk space. You can use the du (disk usage) command to check the size of individual directories.

For example, to check the size of the current directory:

du -sh *

This will list the sizes of all the directories and files in the current directory.

Step 5: Clean Up Unnecessary Files

If you identify that your VPS is running out of disk space, you’ll need to clean up unnecessary files. You can start by deleting old log files, temporary files, and other unused data. Be cautious not to delete important system files.

Step 6: Check for Large Log Files

Log files can sometimes grow unexpectedly and consume a lot of disk space. You can check the size of log files in the /var/log/ directory:

sudo du -sh /var/log/*

If you find large log files, you might consider truncating or deleting them if they are not needed.

Step 7: Investigate Running Processes

Large files might be held open by running processes, preventing the space from being reclaimed. You can use the lsof command to identify which processes are holding onto deleted files:

sudo lsof | grep deleted

This will list the processes and the files they are holding.

Step 8: Consider Increasing Disk Space

If your VPS is consistently running out of disk space, it might be a good idea to consider increasing the allocated disk space for your VPS. This can usually be done through your hosting provider’s control panel.

Remember, always be careful when deleting files and make sure you understand what you’re deleting. Deleting important system files or data can lead to server instability or data loss. It’s a good practice to take regular backups before performing any major changes.
