At 2 and 7:30 am this morning engineers noticed a host in our CLOUD Cluster experiencing vSAN stability issues.
Host ESX 11 stalled and was unresponsive, VMware HA did not kick in and a manual power cycle was required forcing the host to release VM's so they could be (vMotioned) moved to other available hosts.
The host has been placed in maintenance mode awaiting VMware review.
A postmortem will be supplied once logs are collected and reviewed by VMware to identify the root cause of the issue.
