About the health check

This check warns you if the free disk space for your Confluence home directory falls below the recommended threshold. In clustered Confluence Data Center installations, this is called the local home directory.

What is the recommended threshold?

The recommended threshold is calculated as either a percentage of the overall disk partition where your local home directory lives, or an absolute size, whichever is smaller:

  • 10 GB, or
  • 10% of the overall disk partition.

The formula we use depends on if your hard disk space is less than 100GB or greater than 100GB.

If you have more than 100GB total partition disk space, we warn you if your free disk space falls below 10GB, because it’s lower than the minimum size threshold.

If you have less than 100GB total partition disk space, we warn you if your free disk space falls below the 10% threshold, because it's lower than the minimum size threshold.

So as an example, if you have 20GB total partition disk space, we warn you if your free disk space falls below the 2GB, because it's lower than the minimum size threshold (10%).

結果の確認

アイコン結果What this means
(tick) PassYour free disk space is more than, or equal to, the recommended threshold.You have enough free disk space for Confluence to operate safely.
(tick) PassWe can't verify the free disk space.This usually happens because we can’t find the location of your local home directory, or if the application doesn't have access to the home directory. You can manually perform this check by reviewing your free disk space.
(warning) 警告The free disk space is below the recommended threshold. Your free disk space is running low. If the disk becomes full, Confluence functionality will be affected.

What happens if I ignore the warning?

If the disk partition allocated to your home directory becomes full, Confluence will be unable to write things like log files or scheduled backup files to disk. Users will also see an error when attempting to upload files if the drive where attachments are stored has run out of space.

For clustered Data Center installations, attachments won’t be affected because they are stored in the shared home directory. Learn more about what's stored in the home directory.

ソリューション

1. Review your current disk usage

It’s a good idea to check your current disk usage first, and free up some space if you can. Log files and backups can consume large amounts of space, so it’s worth looking for:

  • Old log backups
  • Old or excessively large log files
  • Old automated XML backups.

Specific directories you may want to check:

ディレクトリ詳細

アプリケーション ログ

<confluence-home>/log/

By default, Confluence keeps 5 log files, which are overwritten as they reach 20 MB. If you’ve manually changed the default settings, these may be consuming more space than necessary. See Working with Confluence Logs for details.

Backup directory

<confluence-home>/backups

Depending on your configuration, backups can also consume a large amount of space. See Configuring Backups for details.


You can also check the OS (Operating System) disk usage.

2. Provision additional disk space

If you're not able to free up enough disk space, you’ll need to provision additional space to the disk partition that stores your local home directory.
