The cluster continuously monitors the connectivity quality of the storage network between hosts. When a host's packet loss rate or latency is significantly higher than that of others, the host is automatically quarantined to avoid impact on services.
The host { .labels.hostname } has a fail slow and is being automatically quarantined.
The host { .labels.hostname } has a fail slow.
The affected host may have high latency or packet loss, or may be unable to send or receive traffic, which can impact the performance of virtual machines running on the node.
The host's storage network may enter a fail-slow state due to the following reasons, resulting in degraded communication quality with other nodes.
NIC or driver failure
Optical module failure
Failure or congestion on the upstream link connected to the NIC
Refer to the troubleshooting steps for the network packet loss or high latency alerts. The alert will disappear automatically after the network issue is resolved.
