Fixed Issues

• Subfolder permissions would not be consistent with those of their parent folders when granting permissions to a domain user whose name was too long.
• The QXG-10G2T-107 network expansion card could not function normally after users updated QuTS hero to h4.5.4.
• Certain users could not successfully update ClamAV virus definitions.
• QuTS hero occasionally could not update virus definitions if users chose to check for virus definition updates every day.
• Users sometimes could not finish updating the virus definitions from ClamAV.
• Some users could not upload files to File Station due to unexpected permission errors.
• Static Route would stop functioning after a network adapter was connected or disconnected.

Other Changes

Storage & Snapshots

• To ensure data security, system stability, and storage performance, the maximum number of drives for a single RAID group is now 16 (applicable to RAID 5, RAID 6, RAID TP, and subgroups of RAID 50 and RAID 60). Nevertheless, users can combine multiple RAID groups into a large storage pool that contains more than 16 drives, using RAID 50, RAID 60, or RAID 10 as the RAID configuration. This enhancement will only be applied to new RAID groups. All existing RAID groups and storage systems will not be affected.
