Disk Notifications for JSA Appliances

 

Asset Persistence Queue Disk Full

38750113 - Asset Persistence Queue Disk Full.

Explanation

The system detected the spillover disk space that is assigned to the asset persistence queue is full. Asset persistence updates are blocked until disk space is available. Information is not dropped.

User Response

Reduce the size of your scan. A reduction in the size of your scan can prevent the asset persistence queues from overflowing.

Asset Update Resolver Queue Disk Full

38750115 - Asset Update Resolver Queue Disk Full.

Explanation

The system detected that the spillover disk space that is assigned to the asset resolver queue is full.

The system continually writes the data to disk to prevent any data loss. However, if the system has no disk space, it drops scan data. The system cannot handle incoming asset scan data until disk space is available.

User Response

Review the following options:

  • Ensure that your system has free disk space. The notification can accompany SAR Sentinel notifications to notify you of potential disk space issues.

  • Reduce the size of your scans.

  • Decrease the scan frequency.

Disk Failure

38750110 - Disk Failure: Hardware Monitoring has determined that a disk is in failed state.

Explanation

On-board system tools detected that a disk failed. The notification message provides information about the failed disk and the slot or bay location of the failure.

User Response

If the notification persists, contact Juniper Customer Support or replace the parts.

Disk Full for the Asset Change Queue

38750117 - Asset Change Listener Queue Disk Full.

Explanation

The asset profile manager includes a process, change listener, that calculates statistics to update the CVSS score of an asset. The system writes the data to disk, which prevents data loss of pending asset statistics. However, if the disk space is full, the system drops scan data.

The system cannot process incoming asset scan data until disk space is available.

User Response

Select one of the following options:

  • Ensure that your system has sufficient free disk space.

  • Reduce the size of your scans.

  • Decrease the scan frequency.

Disk Replication Falling Behind

38750103 - DRBD Sentinel: Disk replication is falling behind. See log for details.

Explanation

If the replication queue fills on the primary appliance, system load on the primary might increases. Replication issues are commonly caused by performance issues on the primary system, or storage issues on the secondary system, or bandwidth problems between the appliances.

User Response

Select one of the following options:

  • Review bandwidth activity by loading a saved search MGMT: Bandwidth Manager from the Log Activity tab. This search displays bandwidth usage between the console and hosts.

  • If SAR sentinel notifications are recurring on the primary appliance, distributed replicated block device (DRBD) queues might be full on the primary system.

  • Use SSH and the cat /proc/drbd command to monitor the DRBD status of the primary or secondary hosts.

Disk Storage Available

38750093 - One or more storage partitions that were previously inaccessible are now accessible.

Explanation

The disk sentry detected that the storage partition is available after the notification from Disk storage unavailable appeared. Disk unavailability was resolved.

User Response

No action is required.

Disk Storage Unavailable

38750092 - Disk Sentry has detected that one or more storage partitions are not accessible.

Explanation

The disk sentry did not receive a response within 30 seconds. A storage partition issue might exist, or the system might be under heavy load and not able to respond within the 30-second threshold.

User Response

Select one of the following options:

  • Verify the status of your /store partition by using the touch command.

If the system responds to the touch command, the unavailability of the disk storage is likely due to system load.

  • Determine whether the notification corresponds to dropped events.

JSA drops events when it cannot write events to disk. Investigate the status of storage partitions.

Disk Usage Exceeded Max Threshold

38750038 - Disk Sentry: Disk Usage Exceeded Max Threshold.

Explanation

At least one disk on your system is 95% full.

To prevent data corruption, some processes are shut down. Event collection is suspended until the disk usage falls below 92%.

User Response

Identify which partition is full, such as the / and /store file systems. Free disk space by deleting files that are not required. For example, remove debug output and patch files from the / file system. If the /store file system is at 95% capacity, look to the subdirectories to determine whether you can move the files to a temporary location or you can delete any files.

Note

If the files are deleted, you cannot search these events.

You can also manually delete older data in the /store/ariel/ directories. The system automatically restarts processes after you free enough disk space to fall below a threshold of 92% capacity.

Disk Usage Exceeded Warning Threshold

38750076 - Disk Sentry: Disk Usage Exceeded warning Threshold.

Explanation

The disk sentry detected that the disk usage on your system is greater than 90%.

When the disk space on your system reaches 95% full, the system disables processes to prevent data corruption.

User Response

You must free some disk space by deleting files or by changing your data retention policies. The system can automatically restart processes after the disk space usage falls below a threshold of 92% capacity.

Disk Usage Returned to Normal

38750077 - Disk Sentry: System Disk Usage Back To Normal Levels.

Explanation

The disk sentry detected that the disk usage is below 90% of the overall capacity.

User Response

No action is required.

Insufficient Disk Space to Export Data

38750096 - Insufficient disk space to complete data export request.

Explanation

If the export directory does not contain enough space, the export of event, flow, and offense data is canceled.

User Response

Select one of the following options:

  • Free some disk space in the /store/exports directory.

  • Configure the Export Directory property in the System Settings window to use to a partition that has sufficient disk space.

  • Configure an offboard storage device.

Predictive Disk Failure

38750111 - Predictive Disk Failure: Hardware Monitoring has determined that a disk is in predictive failed state.

Explanation

The system monitors the status of the hardware on an hourly basis to determine when hardware support is required on the appliance.

The on-board system tools detected that a disk is approaching failure or end of life. The slot or bay location of the failure is identified.

User Response

Schedule maintenance for the disk that is in a predictive failed state.

Process Monitor Must Lower Disk Usage

38750045 - Process Monitor: Disk usage must be lowered.

Explanation

The process monitor is unable to start processes because of a lack of system resources. The storage partition on the system is likely 95% full or greater.

User Response

Free some disk space by manually deleting files or by changing your event or flow data retention policies. The system automatically restarts system processes when the used disk space falls below a threshold of 92% capacity.
