CLUSTER_CSV_CLUSSVC_DISCONNECT_WATCHDOG
Cluster CSV disconnect watchdog for CLUSTER_CSV_CLUSSVC_DISCONNECT_WATCHDOG
CLUSTER_CSV_CLUSSVC_DISCONNECT_WATCHDOG is bug check code 0x00000170.
Microsoft documents this bug check as a cluster disconnect watchdog: the cluster disconnect path is not making forward progress. It is a failover-clustering progress failure rather than a generic storage timeout.
How to read it in a dump
- Parameter meanings are described by the Microsoft bug check page for the specific Windows build.
- The dump should be correlated with cluster service state, CSV ownership, node communication, and disconnect path workers.
- This is a watchdog condition; the system stopped because progress did not happen in time.
What to check
- Collect cluster logs and compare with the dump timestamp.
- Check cluster network, storage fabric, CSV ownership transitions, and filter-driver stalls.
- Analyze blocked cluster service threads in the dump.
