3.7.61

Added the ability to store filesystem metadata on an SSD pool. This feature, known as "packed metadata", is useful for large filesystems in an HDD pool to speed up metadata operations.
- Contact StorONE Support for assistance enabling this feature.
- This feature is applicable only for new volumes created after the feature is enabled. You cannot migrate the filesystem metadata on an existing volume.
- This feature is not currently supported with replication. Volumes created using this feature cannot be replicated, and the feature cannot be removed after volume creation. This means that if you want to replicate a volume that is using this feature, you will need to disable the feature, create a new volume, and replicate the new volume. You can migrate the data from the old volume to the new volume before or after configuring replication.
Updated the garbage collection (GC) mechanism to reduce the frequency of full (blocking) garbage collections, and improve GC performance.
Improved SCSI timeout handling to return BUSY to initiators instead of aborting tasks, allowing initiators to more quickly retry commands. This improves overall system performance and reliability, and reduces VMWare heartbeat timeouts that generate datastore disconnect/reconnect events.
Improved handling for memory buffers for reads and writes.
Improved resource management to increase memory and CPU utilization efficiency.

Improve API available for HA nodes with one node down.
Set internal sync flag for NAS volume mounts to reduce HA transition time for the NAS server.

Updated internal concurrency and timeout settings to improve object store performance and reliability.
Reduced the time taken to clean up deleted files.

Improved snapshot deletion scheduler to always delete a single snapshot at a time, and to allow parallel snapshot deletions if the volumes reside on different controller nodes. This improves overall system performance and reduces resource contention.

Fixed issues with the support tunnel.
Fixed a rare issue where different configuration changes had the same version ID.
Fixed an issue with vRAID+ volumes (volumes striped across multiple drive pools) that would not load after a restart.
Fixed an issue with modifying the tier size on vRAID+ volumes.
Fixed duplicate dead disks declaration.
Fix volume deletion issue.

Fixed issues with generating support packages
Fixed an issue where the 'Tier Data Degradation Histogram' was not displayed for vRAID+ volumes.
Fixed name validation for floating IP to be case-insensitive.

Fixed an issue preventing deleting host mappings using the web UI.
Fixed an issue where clicking the green '+' icon to add a consistency group during the volume creation wizard opened the wrong modal

Fixed an issue starting replication when the SAN volume is locked
Fixed an issue with replication transitions when a default gateway is defined on the replication floating IP.
Fixed a race condition in HA failover on systems with replicated volumes
Fixed an issue with replicated block storage volumes where adding or modifying hosts (including host mappings) caused the system to lock up

Fixed issue with excessive memory consumption when using the VMware vSphere® Storage APIs – Array Integration (VAAI) plugin for NFS datastores.

Fixed an issue where snapshot retention notifications were sent for volumes without snapshots configured

Behavior Changes

The application volumes list --details output now includes the encryption type for encrypted volumes.
The applications filesystem list now includes the IsPackedMetadata attribute to display whether a filesystem is using the new "packed metadata" feature.
