Aria Operations 8.x
/storage/log partition is at 100%. When this log partition is full, services cannot write log to the partition, causing these services to stop running.
SSH as root into the Aria Operations node.
Perform the following command to safely cleanup the log from the log partition: find /storage/log/ -mount -type f -mtime +1 -exec echo {} \; -exec truncate -cs 0 {} \; 2>&1 | tee /tmp/files_truncated.txt
Once the storage issue has been resolved via the cleaning of the log partition, proceed to take cluster offline.
Login to the Aria Operations admin UI. Click on "Take Cluster Offline".
Once cluster is Offline, click on "Take Cluster Online" to bring cluster back Online.
