9.10.3. Configuring Disk Quotas
User quotas enforce disk quotas per gear because each gear corresponds to a system user. The quota values are set in the
/etc/openshift/resource_limits.conf file. Modify these values to suit your requirements.
| Option | Description |
|---|---|
quota_files | The number of files the gear is allowed to own. |
quota_blocks | The amount of space the gear is allowed to consume in blocks (1 block = 1024 bytes). |
Important
The minimum allowed value for the
quota_blocks parameter is 1 GB.
Enable enforcement of disk quotas at the file system level.
Procedure 9.7. To Enable Disk Quotas:
- Consult the
/etc/fstabfile to determine which device is mounted as/var/lib/openshift. In a simple setup, it is the root partition, but in a production system, it is more likely a RAID or NAS mount at/var/lib/openshift. The following steps in this procedure use the root partition as the example mount point. Adjust these to suit your system requirements. - Add a
usrquotaoption for that mount point entry in the/etc/fstabfile.Example 9.7. Example Entry in the
/etc/fstabfileUUID=4f182963-5e00-4bfc-85ed-9f14149cbc79 / ext4 defaults,usrquota 1 1
- Reboot the node host or remount the mount point:
#
mount -o remount / - Generate user quota information for the mount point:
#
quotacheck -cmug / - Fix the SELinux permissions on the
aquota.userfile located in the top directory of the mount point:#
restorecon /aquota.user - Re-enable quotas on the mount point:
#
quotaon /
Verifying the Disk Quota Configuration
Create an application and then run the following command to verify that your disk quota is correct:
# repquota -a | grep gear-uuid
