The system health check may display messages similar to: /cyc_node free space is less than 200 MB. (KB#000198173) Or: Unable to parse passed url (0xE04040020008) The system may display a normal alert like: Root partition usage of node x has exceeded xx% on mount /cyc_node. Note: This alert or issue should not be ignored and must be resolved as soon as possible. If the system health checks detect this condition, PowerStoreOS upgrades may fail, and there is a risk of unexpected reboots. If the partition reaches 100%, SupportAssist may fail, and the node may enter Service Mode. In the following examples, both nodes of an appliance have insufficient space in /cyc_node .

Most causes leading to partition full conditions have been resolved in PowerStoreOS LTS-v4.1.x. After resolving the current condition, update the PowerStore Appliance to PowerStoreOS LTS-v4.1.x or later. Workaround With earlier versions, if both nodes are in normal mode, you may attempt to temporarily disable SupportAssist. Usually, this clears out the SupportAssist files under " /cyc_node. Note: Upon reenabling SupportAssist, the automatic download feature is enabled. If required, this feature can be disabled on the Settings > Upgrades page of the PowerStore UI. Before attempting to disable SupportAssist, verify that the PowerStore is not exposed to PowerStore: Data Collection Fails, and the PowerStore Manager User Interface Reports Abnormal Information . If you suspect that the PowerStore may be experiencing this issue, resolve this first before proceeding to the next steps. Steps to disable SupportAssist from the PowerStore Manager user interface (UI) Settings > Support Connectivity > Connection Type > toggle to Disable and click Apply . Verify that SupportAssist did disable. Once the job appears to have finished, refresh the UI page and see if it shows disabled or enabled. If it shows enabled after a couple of attempts, then disabling SupportAssist from the UI did not work, go to step 5. If it does show disabled after a refresh of the UI page, continue to step 2. Wait at least 15 minutes. Reenable SupportAssist . Note: Even is enabling SupportAssist fails, it should be enough to reset this partition and clear the space. If SupportAssist fails to enable, normal troubleshooting should be carried out. Check /cyc_node partition on both nodes over SSH using the command: df -h If the issue persists, a further self-service action is to install and use the svc_partion_cleanup service script to clean up the root partitions .
