Enhancements

• On the NAS initialization page, added information on the disks' associated NAS host ID when the system detects disks coming from another QNAP NAS.
• Added information on the format of system logs on the "Syslog Client Management" page in Control Panel.

Security Updates

• Fixed security issues.

Fixed Issues

• Fixed an issue that caused one-way trusted domain users to appear in the user drop-down list even though QES only supports two-way trusted domains.
• Fixed a counting bug in Resource Monitor that sometimes caused the active controller to crash and restart repeatedly.
• Fixed an issue that caused SnapSync jobs to fail when the source NAS contained a huge file.
• Fixed a bug that caused the system to display an "Unknown error" message after deleting an iSCSI ACL rule.
• Improved the LUN status checking mechanism to ensure LUNs can be reconnected after a firmware update.
• Modified the disk checking mechanism to ensure that storage pools can be brought online again after going offline.
• Fixed a rare issue that caused SSDs to become undetectable after a firmware update.
• Fixed an issue where the inconsistent role of a faulty system disk would cause the NAS to become uninitialized after a restart.
• Corrected the format of system logs when they are exported to a NAS running a different operating system, so that information is displayed correctly.
• Fixed an issue where controller takeover would occur due to a false alarm from the pool capacity becoming almost full.
• Several minor bug fixes.

Other Changes

• Removed some unused authentication system logs.
