# Resolved Issues in 5.3.2-SP4

## Networking

- ORION-268912: Resolved an issue where an attempt to modify EBox NTP settings by running a cluster networking reconfiguration task encountered multiple CNode container restarts with the `assertion failed: ((!is_raided_layout_safe() || _rio_control->is_dnode_group_deactivate_allowed(dynamic_cast<DNode *>(node_arg)))) can't deactivate dnode=<...>: can reach DU` error.
- ORION-234305: Improved the routines responsible for representation of cluster's NICs in the VMS to prevent false-positive OBJECT_DELETED and OBJECT_CREATED alerts for the NICs.
- ORION-225205: Resolved an issue with NIC status alarm generation that could cause false cable disconnection alarms.
- ORION-217068: Resolved an issue where following a link state change from UP to DOWN, no notification email arrived although the event was reported by the VMS.

## Encryption of Data at Rest

- ORION-268265: Improved handling of an EKM flow that involved a deleted EKM master key to avoid potential CNode container restarts.

## NFS

- ORION-262208, ORION-256109: Enhanced handling of client atime when processing NFS3 SETATTR requests against WORM-enabled views to prevent the client from getting errors in scenarios where the client atime is sent shortly after file creation.
- ORION-261965: Made updates to tenant resolution routines to resolve an issue where NFS clients encountered intermittent `RPC Error Program Unavailable` errors for NFS mount requests.

## SMB

- ORION-264823: Resolved an issue that could cause CNode containers to restart with the `(next(index) == INVALID_INDEX)` error during SMB request processing.

## S3

- ORION-260816: ORION-260816: Updated handling of VAST S3 rename operations so that the cluster rejects a request to rename a directory if the target directory already exists.

## Protocol Auditing

- ORION-239532: Resolved an issue where an `Invalid UTF8 sequence` error occurred when trying to query the VAST audit log.

## VAST Catalog

- ORION-254370: Made updates related to how deletions are handled in VAST Catalog to resolve an issue that could cause an ESTORE BIG_CATALOG deny list alert on the cluster.

## Replication

- ORION-269010: Resolved an issue that could cause synchronous replication to get stuck in the *Becoming Synchronous Replication* state.
- ORION-267043: Fine-tuned internal communications related to asynchronous replication to prevent a flow that could cause `Connection to Remote Peer <...> is not healthy: Communication Error` alerts on the source replication peer.
- ORION-265913: Improved handling of replicated identity policies in NDUs to prevent a flow where existing policies could be discarded due to reaching the maximum allowed number of policies per identity during an upgrade.
- ORION-225188: Eliminated a replication-related flow that could cause VMS to restart due to an out-of-memory condition.

## VMS

- ORION-269081: Resolved an issue that could cause an `Exceeding the max number of host-based rules for nfs. Limit per protocol is 2048` error while the actual number of the rules being less than the cluster limit.
- ORION-268925: Made updates to ensure that VAST Prometheus Exporter exports PSU metrics values for SuperMicro Gen5 CBoxes.
- ORION-264000: Made updates to ensure that the LED on/off capability in VMS switches the LEDs on or off as expected, with the Led Status column in VAST Web UI showing a correct status for the LEDs.

## VAST Web UI

- ORION-272484: Adjusted the way VAST Web UI displays VLAN information for cluster nodes so that:

  - The VLAN ID column in the Infrastructure -> CNodes page shows a correct management VLAN ID for each CNode.
  - The Infrastructure -> DNodes page does not include a VLAN ID column.

## Platform & Control

- ORION-260678: Resolved an issue that could cause incorrect CBox serial assignment on a newly added CNode following a CNode replacement procedure.
- ORION-259500: Resolved an issue that could cause a CNode container to restart with the `((gen_guard) != (nullptr)) (0 != nullptr) attempted to add to the references cache without a generation guard` error.
- ORION-256997: Resolved an issue that could cause CNode containers to restart due to `Fiber=<...> group=_MIGRATE had a suspension timeout` errors.
- ORION-236751: Resolved an issue that could cause a CNode container to restart with the `((_memory_client_counter) > (0)) (0 > 0)` error when processing NFSv4.1 workload.
