Hi Everyone,

One of my customer experienced having Storage Lost Sync during intensive usage of CPU (95%), they are executing SQL Queries on MySQL Database. While executing the Queries on Node 1 of Cluster 1 and the Storage Lost Sync appeared, then all VMs on Node 2 are unresponsive...

Hi DeclanOR,

Sorry but currently we don't have any access on the nodes, it was only the customer adminisstrator who explained it to me. According to him, when the CPU Usage reaches 95% of the utlization the Lost Sync error prompts, and VM's on other cluster starts to be frozen. What are other reasons why it happens?
