Storage Manager:

If you want to use Windows ACL you must use the EXT4 file system. If you are just setting up a new DiskStation I would recommend using EXT4 because there are benefits to the file system, and you would be making your life much easier if you ever want to use Windows ACL.

If you have a volume created with DSM 2.x, you will need to do the following:

» Backup all data from the volume (including configuration)
» Remove the existing volume
» Create a new volume using DSM 3.0 (there is no option to pick file system, but it defaults to EXT4)
» Restore configuration
» Restore data

Synolgy included two Seagate 1TB 7200RPM SATA hard drives for the review of the Synology DiskStation DS411+ NAS.

The two included Seagate 1TB 7200RPM hard drives with RAID 1 [Mirrored Array] took just under 4hrs 30mins to build the volume using the new EXT4 file system. During the volume creation, you cannot do much else. You cannot setup Shared Folders or do much with the applications.

In the following images below, you can see the steps necessary to build a RAID 1 volume using two hard drives.





The image below is where you would be checking every so often to see the progress of the volume creation. In addition to the percent complete, I would love to see an estimated completion time in the Storage Manager.



The image below shows the Resource Monitor just after the creation of the EXT4 file system had completed. The DSM uses almost all of the 1024MB of RAM during the file system creation.



I added another 1TB 7200RPM hard drive to the DS411+ and changed the RAID 1 volume to a RAID 5 volume. Doing the migration took about 20 hours to complete. So now I have just under 2TB of redundant storage.
