Important Notes

• QuTS hero does not support downgrading from h5.1.x to h5.0.1 or earlier. Downgrading firmware can be risky. Please make sure you fully understand and accept the risks if you decide to downgrade your firmware.
• This version is released in a staged rollout, which means we initially release this version to a small portion of users and then gradually reach more users over time.

Security Updates

• Applied multiple security updates to further enhance system security.

Enhancements

Storage & Snapshots

• Implemented support for "Space Low" status to effectively manage storage pools nearing capacity limits. Additionally, introduced the "Increase Pool Free Space" function to streamline capacity-saving methodologies within the pool.

iSCSI & Fibre Channel

• Users can now import LUNs exported from QTS. (Previously, users could only import a LUN if the source and destination NAS devices ran the same operating system.)

Other Changes

Storage & Snapshots

• Implemented reserved space for storage pool to enhance capacity utilization for system, applications, and on-demand storage requirements.

Fixed Issues

• Improved the NAS login speed when the NAS is configured as a domain controller.
• Fixed an issue where a power schedule configured to run only once would end up running once every year.
• Fixed an issue where after configuring the NAS as a domain controller, restarting the NAS could change the DNS interface settings, causing users to become unable to connect to the NAS.
• Fixed an issue where under certain rare conditions, disabling or deleting user accounts could cause unexpected changes to the user group configuration file.
• Resolved an issue in Control Panel > Network & File Services > Network Access > Reverse Proxy, where if two rules were configured with the same source, after disabling one of the rules, users could not enable the rule again unless the other rule was also disabled.
• Fixed an issue where connecting to a domain name that had been configured as the source of a reverse proxy rule would unexpectedly redirect to the NAS login page, even though users had not yet mapped the domain name.
• Resolved an issue where after removing Multimedia Console from App Center, the system still displayed the "Multimedia Services" status as "Enabled" in System Status > System Service.
• Fixed a French translation issue in Control Panel > Privilege > Users.
• Fixed an issue where after enabling passwordless login, and then logging in with "Keep me logged in" selected, the "Keep me logged in" function would fail to activate and the user would have to log in again the next time.
• In File Station, the advanced folder permission setting "Only admin can create files and folders" has been corrected and revised to "Only users in the administrators group can read/write the files and folders", matching the same setting available in Control Panel.
• Fixed a File Station issue where if a scroll bar appears due to a large number of files in the folder, Windows users could not use CTRL + left-click to select the files that require scrolling to view.
• In File Station, a share link's DDNS URL now correctly uses the domain name instead of the IP address if a DDNS service has been configured.
• Addressed an issue where if the myQNAPcloud app was open, users could not open Microsoft Office files using the "Edit with Office Online" or "View in Google Docs" function in File Station.
• Resolved an issue in HBS where running a sync job from a QTS NAS to a QuTS hero NAS could sometimes cause the QuTS hero NAS to run out of memory if the job setting "Replicate ACL and extended attributes" was enabled.
• Fixed a debug logging issue that caused HBS 3 sync jobs to a remote NAS to run slowly if the source contained a WORM folder.
• Addressed a rare issue in HybridMount where a user might unexpectedly lose access permissions to an SMB remote folder after network reconnection.
• Resolved a rare issue in iSCSI & Fibre Channel where iSCSI target creation could become unresponsive if the IPv6 address of a selected network interface was too long.
• Fixed an issue in myQNAPcloud > DDNS > IPv4 adress > Settings, where after specifying an IP address, users were unable to click the "Apply" button if IPv6 was enabled for the system default gateway.
• Addressed an issue where under certain conditions Notification Center could not open properly.
• Network & Virtual Switch now no longer applies previously configured DNS server addresses to a virtual switch after the user configures blank values for the DNS server address fields.
• Resolved an issue where if a virtual switch was configured as the default gateway and NAT was enabled on the virtual switch, the NAS would lose its WAN IP address after a system restart.
• Fixed an issue where if the physical adapter used by the QXG-10G1T network expansion card was bound to a virtual switch, after the NAS woke up from sleep mode, the expansion card would fail to connect to the internet.
• Users can now successfully rename a file or folder via SMB even if the name change involves multibyte characters.
• Resolved a rare issue where the system would not automatically run scheduled SnapSync jobs for some users.
• Fixed an issue in Storage & Snapshots where under certain conditions the Create a Snapshot Replication Job wizard would display an incorrect size for the source data.
• Fixed an issue in Storage & Snapshots where after reverting a shared folder using a remote snapshot, the process would finish successfully but the shared folder would display an "Error" status.
• The "Edit Shared Folder Permission" window in Control Panel now no longer counts hidden folders in the total number of displayed folders.
• Fixed an issue where after safely detaching a storage pool consisting of only M.2 SSDs and then reinitializing the NAS, some users could not successfully import the pool back onto the NAS.
• Users can now successfully reattach a storage pool even when it contains folders with certain special characters in their names.
• Fixed an issue where after a disk failed and was replaced with a healthy disk, Storage & Snapshots would incorrectly label the healthy disk as unsuitable for rebuilding the RAID group when it was another disk in the RAID group that was faulty.
• Resolved an issue on the TVS-1282T3 where users could not connect to the NAS via two of its Thunderbolt ports after a firmware update.
• Addressed an issue for some users where the system could not shut down properly under certain conditions.
