Symptoms

In rare cases, rootFS may start filling up due to numerous logs being created on an impacted node.

Cause

Log rotation for internal Fabric logs that are small in size may not work as expected, causing these logs to accumulate on the node.

Resolution

  • ECS Engineering has implemented a fix to address these potential log rotation issues
    • FABRIC-9928/FABRIC-10023: Fix potential uncontrollable growth of fabric agent logs, which avoids data unavailability caused by rootFS running full.
  • It is recommended to upgrade to a code version which includes these log rotation fixes:
    • For ECS 3.8.0.x:
      • ECS 3.8.0.3 General Availability (GA) and above for the rest of the 3.8.0.x family.
      • ECS 3.8.0.2 General Patch 2 (GP2) and newer GPs.
    • For ECS 3.7.0.x:
      • ECS 3.7.0.6 General Patch 1 (GP1) and above for the rest of the 3.7.0.x family
