## Summary - Adds cross-platform disk space check policies (macOS, Windows, Linux) scoped to the workstations team - Each policy calculates the percentage of available disk space relative to total disk space and **fails when available disk space is 10% or less** - macOS/Linux policies query the `mounts` table for the root partition (`/`); Windows policy queries the `logical_drives` table for NTFS drives - Resolution contact channel is `#help-it` ### New files - `it-and-security/lib/macos/policies/disk-space-check.yml` - `it-and-security/lib/windows/policies/disk-space-check.yml` - `it-and-security/lib/linux/policies/disk-space-check.yml` ### Modified files - `it-and-security/teams/workstations.yml` — registers the three new policies ### How it works | Platform | Query logic | |---|---| | macOS | `SELECT 1 FROM mounts WHERE path = '/' AND CAST(blocks_available AS REAL) / blocks > 0.10` | | Linux | `SELECT 1 FROM mounts WHERE path = '/' AND CAST(blocks_available AS REAL) / blocks > 0.10` | | Windows | `SELECT 1 WHERE (SELECT CAST(SUM(free_space) AS REAL) / SUM(size) FROM logical_drives WHERE file_system = 'NTFS') > 0.10` | - **Pass (returns rows):** available disk space is more than 10% - **Fail (returns no rows):** available disk space is 10% or less ### Why >10% free disk space matters Each policy description now includes context on why maintaining sufficient free disk space is important: - **System stability:** Low disk space can cause system instability, slowdowns, and crashes - **OS requirements:** Operating systems need free space for virtual memory/swap, temporary files, and system updates - **Application reliability:** Applications may fail to save data or function properly when disk space is critically low - **Data protection:** Keeping sufficient free space ensures reliable performance and prevents data loss Built for [Allen Houchins](https://fleetdm.slack.com/archives/D0AFASNBZMW/p1772934328893319?thread_ts=1772933835.386689&cid=D0AFASNBZMW) by [Kilo for Slack](https://kilo.ai/features/slack-integration) --------- Co-authored-by: kiloconnect[bot] <240665456+kiloconnect[bot]@users.noreply.github.com>

- name: Linux - Sufficient disk space available

query: SELECT 1 FROM mounts WHERE path = '/' AND CAST(blocks_available AS REAL) / blocks > 0.10;

critical: false
|

description: >-
|
|
This policy checks if more than 10% of disk space is available on the root partition. Devices with 10% or less available disk space will fail this policy.
|
|
Having more than 10% of disk space available is important because low disk space can cause system instability, slowdowns, and crashes.
|
|
Operating systems need free space for virtual memory/swap, temporary files, and system updates.
|
|
Applications may fail to save data or function properly when disk space is critically low.
|
|
Keeping sufficient free space ensures reliable performance and prevents data loss.
|
|
resolution: |-
|
|
Free up disk space by removing unnecessary files, clearing package caches, or uninstalling unused applications.
