Chapter 3. Checking disk space using IdM Healthcheck
You can monitor the Identity Management server’s free disk space using the Healthcheck tool.
For details, see Healthcheck in IdM.
3.1. Disk space healthcheck test
The Healthcheck tool includes a test for checking available disk space. Insufficient free disk space can cause issues with:
- Logging
- Execution
- Backups
The test checks the following paths:
| Paths checked by the test | Minimal disk space in MB |
|---|---|
|
| 1024 |
|
| 512 |
|
| 1024 |
|
| 512 |
|
| 512 |
|
| 512 |
To list all tests, run the ipa-healthcheck with the --list-sources option:
# ipa-healthcheck --list-sources
You can find the file system space check test under the ipahealthcheck.system.filesystemspace source:
- FileSystemSpaceCheck
This test checks available disk space in the following ways:
- The minimum raw free bytes needed.
- The percentage — the minimum free disk space is hardcoded to 20%.
3.2. Screening disk space using the healthcheck tool
Follow this procedure to run a standalone manual test of available disk space on an Identity Management (IdM) server using the Healthcheck tool.
Since Healthcheck includes many tests, you can narrow the results by:
-
Excluding all successful test:
--failures-only -
Including only space check tests:
--source=ipahealthcheck.system.filesystemspace
Procedure
To run Healthcheck with warnings, errors and critical issues regarding available disk space, enter:
# ipa-healthcheck --source=ipahealthcheck.system.filesystemspace --failures-only
A successful test displays empty brackets:
[]
As an example, a failed test can display:
{
"source": "ipahealthcheck.system.filesystemspace",
"check": "FileSystemSpaceCheck",
"result": "ERROR",
"kw": {
"msg": "/var/lib/dirsrv: free space under threshold: 0 MiB < 1024 MiB",
"store": "/var/lib/dirsrv",
"free_space": 0,
"threshold": 1024
}
}
The failed test informs you that the /var/lib/dirsrv directory has run out of space.
