Fixed Issues

• Fixed an issue that might cause system failure due to insufficient storage space on the system partition.
• Fixed an issue where the NCSI (Network Connectivity Status Indicator) service did not check enough servers for verifying network connectivity, causing false network disconnection warnings.

Known Issues

• QTS and QuTS hero with newer kernel versions do not support ATTO Fibre Channel adapters. If you have already installed an ATTO Fibre Channel adapter on your device, we do not recommend updating the firmware to QTS 5.0.1 or QuTS hero h5.0.1 for the time being.
• Thunderbolt connection between the NAS and Mac sometimes cannot automatically resume after users restart the NAS.
• Users cannot connect to the destination NAS of a Snapshot Replica job if their usernames contain a space.
• After waking up from sleep, the TS-x51 and TS-x53 models cannot detect external drives that do not support sleep mode.
• Network connection issues may occur when users add both 10 GbE ports of the QXG-10G2SF-CX4 network expansion card to a virtual switch.
• Users sometimes cannot switch between different FEC (Forward Error Correction) modes for the QXG-25G2SF-CX6LX network expansion card.
• On some earlier NAS models with ARM processors, heavy I/O operations may cause network connection issues for the QNA-UC5G1T USB-to-Ethernet adapter.
• The TS-453D cannot detect the TL-WN823N wireless USB adapter.
• Some users cannot access share links in File Station when the share link database is locked due to a failed database check. Note that the issue fix in our upcoming QTS release may not directly restore access to existing share links. You may need to manually retrieve the old database file or create new share links. If your device is affected by this issue, check System Event Log for more information and contact QNAP Technical Support for further assistance when necessary.
