QNAP TS-451 Initial Startup With Migrated Hard Drives

When I did the initial unboxing post of the QNAP TS-451 NAS I wrapped it up by mentioning that I needed to make sure I had compatible hard drives.


I previously reviewed the QNAP TS-269L 2-bay NAS using a pair of WD Red 3TB hard drives and I confirmed on the compatibility list that these drives are also compatible with the TS-451.

When I had wrapped up the TS-269L evaluation and returned the NAS to QNAP I had pulled the drives and stored them away.  I decided to pull them out of storage and install them in the TS-451.  My first surprise was that I could find only 1 of the 2 drives.  After looking in every possible location in my home, I have come to the realization that I may have sent it to QNAP when I returned the TS-269L.  The data on the drive was nothing critical and I was just using the drives to test and evaluate the NAS anyways.  With only 1 drive available I installed the WD Red drive into the 1st drive carrier of the TS-451 and installed the 4 mounting screws.


After inserting the drive carrier into slot 1 and powering on the NAS,  I tried to log in using the default admin account and password.  To my surprise it wouldn’t accept the password.  After trying a few more times I decided to try logging in with the admin account and password I had been using on the TS-269L.  To my surprise it worked.  I was taken directly to the QNAP desktop in my web browser.

So what happened and why was it using my existing password?  What I quickly realized is the NAS recognized that the drive I had installed had come from another QNAP NAS and the system was migrating from the old system to the new one.  QNAP covers Migrating from Old NAS in their user manual.  A user can migrate their QNAP NAS to another Turbo NAS model with all the data and configuration  retained by installed the hard drives of the original NAS in the new NAS according to the original hard drive order and then restarting the NAS.  Please note that this only works if the new NAS has equal to or a greater number of drive slots over the original.  Since the TS-269L was a 2-bay NAS and I had been running the drives in RAID 1 configuration the drive I had just installed could be considered the first drive from the old NAS.

I checked the disk volume and sure enough the directory structures and files I had been using for my previous evaluation were all still there.

Of course with only 1 drive installed the Raid volume was degraded.

A quick purchase later I had 2 new WD Red 3TB drives at my house.  I mounted both of them on drive carriers and placed them into the NAS in the Disk 2 and Disk 3 slots.  With a new drive installed as Disk 2 the Raid 1 volume started rebuilding.

The rebuilding process does take time (7 hours and 25 minutes according to my system log) but I just let it go and went and did other work.


Disk 3 was also now available in the NAS but since I hadn’t done anything with it yet it was still unavailable for use.  I could create a new volume using just Disk 3  which would create a single 2.7TB volume.  I can also designate the drive as an enclosure spare.  An enclosure spare drive can be used to replace a failed hard disk drive in a RAID 1, RAID 5, RAID 6 or RAID 10.  Since I only have 3 drives of the same size available right now I have gone with a 3rd option.  I can take my original RAID 1 volume and migrate it to RAID 5 using all 3 disks.

Once the system is done I now have a volume with 5.44 TB available to use.

Other Options

I should also mention that I didn’t need to migrate my old drives to the new NAS.  I could have initiated a Restore to Factory Default.  This would have wiped the drives clean including eliminating any user accounts, shared folders and system settings.

I don’t plan on going into depth on showing how user accounts and the other setup options are configured on the NAS.  QTS is the operating system run on every QNAP NAS.  This common interface allows a user or administrator to switch one from piece of hardware to the next and see the same interface.  If you would like to see more about my experience with QTS and some of the configurations I did please check out the posts I did on the TS-269L.

My next post will start looking at the QNAP apps and capabilities of the TS-451 with multimedia including transcoding, streaming and even using the TS-451 as a HTPC.
