Chapter 4. Monitoring Acronis Storage Clusters
4.5 Monitoring Physical Disks
The S.M.A.R.T. status of physical disks is monitored by the smartctl tool installed along with Acronis. The tool is
run every 10 minutes as a cron job also added during Acronis installation. The smartctl tool polls all physical disks
attached to Hardware Nodes in the cluster, including caching and journaling SSDs, and reports the results to
the MDS server.
Note: For the tool to work, enable the S.M.A.R.T. functionality in Node’s BIOS.
You can view disk poll results for the last 10 minutes in the output of the vstorage top command. For example:
