Compatibility

• ES1640dc/ES1640dc v2

Fixed Issues

• It was not possible to access a LUN while deleting a file from the LUN using SMB if deduplication was enabled on any shared folder or LUN in the LUN's storage pool.
• The NAS could not join an active directory domain that contained 200,000 users.
• Creating an Rsync job would fail if the username for the destination server contained any special characters.
• Linux clients could not mount or list shared folders using NFSv3 if the QES DNS settings were invalid.
• It was not possible to create a shared folder in a storage pool after powering off the NAS, unplugging drives in the storage pool, powering on the NAS, performing a NAS firmware update, and then reinserting the drives into the NAS.
• Disabling Synchronous I/O on an iSCSI LUN could result in memory leaks.
• It was sometimes not possible to shut down a storage controller using the command line.
• The battery backup unit (BBU) status LED flashed green to indicate normal, instead of being continuously lit.
• It was not possible to create or view shared folders after updating the NAS firmware if the NAS encountered an abnormal shutdown before the firmware update.
• Scheduled SnapSync jobs would not start after modifying the QES time and SnapSync job settings.

Enhancements

• Reduced the time QES takes to load local users and local groups when configuring shared folder permissions.
• Reduced the CPU load when deleting iSCSI LUN snapshots.
• When a PSU encounters an error, QES dumps the PSU status information to a log in order to help with troubleshooting.
