Timeout error during backup of OCP clusters
Problem
“The execution of the sync command has timed out" error appears during a backup event for OCP clusters.
Cause
This scenario is observed when the cluster is heavily used and the backup event is initiated during peak hours.
Solution
You can restart the nodes, this causes the disk to unmount and forces the operating system to write any data in its cache to the disk. After the restart is complete, initiate another backup. If any warnings appear, scrutinize to verify whether there are any dire warnings, otherwise the generated backup is safe to use. The only drawback in this scenario is the downtime impact, that is the time taken to back up the OCP clusters is longer than usual. Therefore, it is recommended that you back up the clusters during non-peak hours.
If the sync errors continue to appear, contact your IT department to check whether there is an issue with the storage infrastructure which might be preventing the sync command from completing on time.
