Release Notes

Ceph Scale-out Block and Object

  • Updated Ceph Packages available:
- 10.2.7 Jewel for Trusty based installs 
- 0.94.10 Hammer for Precise based installs
  • Fixed Ceph Scale-out Block startup discovery on grid nodes that are still part of a ceph cluster, when one of the ceph nodes in the grid is removed from the grid.
  • Fixed: Added validation to correct an issue where a Grid Node Object and associated child objects were unexpectedly removed from the Grid Master if the QuantaStor Grid Node came onto the network with a new Storage System ID but using the same IP. This corrects a scenario where a system reinstalled in place due to a Hardware issue could cause an unexpected grid or configuration change.


Cloud Containers

  • New IBM Softlayer S3 Endpoints added to the default Cloud Providers configuration.
  • Fixed an issue where changes to the /etc/qs_cloud_providers.conf on the master node was not propagating to secondary nodes.
  • Fixed an issue where the entry fields for Tag and End-Point in the Cloud Containers> Add Provider Location Dialog and CLI were swapped.
  • Fixed a missing python-six dependency issue with the aws CLI tool.


High Availability

  • Improved pool failover times when network interface connectivity between nodes is lost.
  • Fixed an issue where high-availability virtual network interfaces could try and start on a system that did not currently have the QuantaStor service running.
  • Fixed issue where deleting high-availability virtual network interface could cause temporary outages on other high-availability virtual network interfaces.
  • Fixed an issue where deleting a high-availability virtual network interface could cause an unnecessary failover to occur.
  • Fixed an issue where failover would fail due to not finding the disks correctly on the secondary node.
  • Fixed an issue with nginx web service starting during qstormanager package install.
  • Fixed: HA Storage Pool Failover is now kernel panic aware to trigger a failover to the secondary node.
  • Fixed: Deleting a HA VIF from the Network port list in the Storage System View now correctly cleans up the High Availability Failover Group HA VIF object.
  • Fixed: A Site Cluster can now be deleted using the force flag if a Cluster node is Permanently offline and will not be returning.


Disk Management

  • Added a Multipath Configuration Dialog to the Physical Disk section of the Web Manager, this allows for administrators to scan for SAS, FC, iSCSI and other multipath/multiport capable devices and add their white-listing rules to the multipath configuration. This functionality is also available via the new qs CLI 'disk-multipath-config-list, disk-multipath-config-scan, disk-multipath-config-add and disk-multipath-config-remove' commands.
  • Fixed an issue where the /dev/disk/by-id/ata-* devices would be removed under the device mapper path after a Storage Pool is deleted by a user. Previously, a udevadm-trigger command would be required to bring the ata-* device back.
  • Fixed an issue with physical disk scan on multipath configurations that could cause the mutlipath devices to not appear in the QuantaStor WebUi and CLI once the scan completes.
  • Fixed: the qs disk-scan command now has a force flag

Storage Pool

  • Fixed an issue where old disk encryption keys would not be cleaned up after a storage pool is deleted.
  • Added earlier validation checks for Storage Pool Grow Operations for Encrypted Storage Pool configurations to ensure that the disks to be added are not encrypted before the RAID set size and resultant configuration is confirmed to be valid.
  • Fixed an issue during storage pool create where user specified RAID set sizes would not be used.
  • Fixed a few scenarios where creating a Storage Pool with XFS, Software RAID and Encryption could fail.
  • Fixed an issue where a failed disk device was not automatically removed from a ZFS Storage Pool in Multipath configured environments.
  • Fixed an issue that could occur when adding hot spares to ZFS Storage Pools in Multipath configured environments.
  • Fixed an issue where a failed disk device was not automatically removed from a ZFS Storage Pool in Multipath configured environments.

Remote Replication and Snapshots

  • Added a Remote Replication Report tab to the Remote Replication Schedules section of the Web Manager that shows the results of past replication tasks. Statistics in the report include: completion status, average throughput, the start and end time of the replication and many more. This is also available via the qs CLI with the 'qs replica-report-summary-list' and 'qs replica-report-entry-list' commands.
  • Added new snapshot retention options to the Create Remote Replication Schedule Dialog to allow for Daily, Weekly, Monthly and Quarterly Snapshots for Historical Storage Volume and Network Share snapshots.
  • Added new snapshot tags for Daily, Weekly, Monthly and Quarterly Snapshots that correspond with the retention policy picked for a particular Storage Volume or Network Share snapshot.
  • Added Compression support to Storage System Links, this allows for improved performance over slow WAN links.
  • Added: Remote Replication bandwidth throttling has been moved to the Storage System Link object. The qs link-create and link-modify commands and Web Manager Create Storage System Link and Modify Storage System Link Dialogs now allow for setting the bandwidth throttling.
  • Added the ability to turn on Unencrypted support for Remote Replication Storage System Links. This uses mBuffer to provide a high performance unencrypted channel for Remote Replication between QuantaStor nodes.
  • Added the ability to configure the Bandwidth Limiter in the Create and Modify Storage System Link Dialogs.
  • Added more information to indicate replication schedule health/state and cause of failures due to any miss-configuration or networking communication error.
  • Added: Snapshot Schedules can now be created for snapshots (allows Snapshot of Snapshot Scheduling)
  • Fixed an issue where remote replication could fail for manually initated replications.
  • Fixed: Max Replicas in Replication Schedules are now referred to more correctly as Max Delta Points, this clarifies more precisely how many Intermittent and hourly scheduled replica snapshot points are retained between a source and target replication association.
  • Fixed: The Remote Replication Offset interval for Hourly/Daily Replication in the Schedule Interval tab of the Create and Modify Replication Schedule dialogs now defaults to 0 minutes and can go to a max of 59.
  • Fixed: ZFS snapshots will once more be correctly removed upon the deletion of a Network Share snapshot. This corrects a regression from the 4.2.2 release.
  • Fixed: resolved an issue with updating the Timestamps for running remote replication tasks that could result in the remote replication link having incorrect progress information.


Gluster Scale-out File

  • Fixed an issue that could cause unexpected behavior with Gluster Peer and Volume objects showing correctly when Gluster is deployed n the same QuantaStor management grid as non Gluster nodes.
  • Fixed an issue that would prevent cleanup of Gluster Volumes in a configuration where the gluster bricks or underlying pools had been already removed.
  • Fixed: Re-ordered the Ribbon bar icons in the Scale-out File Storage tab.

Network Share:

  • Added the ability to see SMB session information for Network Shares under the new Web Manager Network Share>SMB Sessions tab and the 'qs share-session-list' and 'qs share-get' CLI commands.
  • Added the ability for users to create a snapshot of an existing Network Share snapshot (snapshot of a snapshot). This support is limited to custom named snapshots and not snapshots created by a schedule that has @GMT in the name.
  • Fixed an issue on Precise platforms with Network Share Snapshots for Windows SMB Shadow Copy and File Versioning support.
  • Fixed an issue where removing NFS access from a Network Share would collapse the tree to the first level in the Network Share tree view. Now the tree will stay as expected when a NFS Access object is removed from the share.
  • Fixed an issue in the Namespace Add/remove Network Shares Dialog where changing the namespace in the drop down would not always update the available selections.
  • Fixed an issue with the search filtering in the Add/Remove Network Shares to/from Namespaces.
  • Fixed an Issue with creating shares that have multiple '$' in the name.
  • Fixed an issue with snapshot mount directory cleanup after a network share snapshot has been deleted. Note, this prevents the issue from occurring going forward, If users ran into this case previous to upgrading to the 4.3 release they may need to manually remove old @GMT snapshot mount directories from the network share _snaps directory.

Web Manager

  • Added a new Password Policy dialog available under the Users and Groups tab in the Web Manager that allows Administrators to enforce password Requirements. This includes:
- Minimum password character length 
- Password expiration (in days). 
- Number of allowed login attempts
