When I set up my Synology DS1813+, I transferred 3 pieces of 3 TB SEAGATE hard disks from the Synology DS1511+ over, making it 5 pieces of 3 TB Western Digital RED hard disks and 3 pieces of 3 TB Seagate Hard Disks. This is documented here on this blog post.
Recently I have deciding what to do with the Synology DS1511+. The price in the 2nd hand market is not too encouraging (damn..) and anyway decided to use it as a test machine in another place so have been looking for hard disks to fill it up.
On Black Friday, I bought a few pieces of 3TB Western Digital RED NAS but instead of putting it into the DS1511+, I decided to replace the 3 older Seagate with the RED hard disks and hence making it a completely Western Digital RED DS1813+ :)
This means I need to remove the old 3TB Seagate hard disk and then replace by the newer 3TB Western Digital hard disk. Hence, I am replacing a hard disk of similar capacity in Synology DS1813+.
The Synology DS1813+ comes with screw-less disk cabby so it was easy to fit the hard disks in and out:
I realized I have never done this before and hence blogging about it. It is painless and quite fast (probably due to the processor in DS1813+ and also due to the newer DSM software).
This is how the disk management looks like. 5 RED and 3 Seagate:
Removing the first seagate hard disk with the system online (no shut down necessary) and the disk management changed to:
Plug in your new hard disk and then do a repair of the degraded array:
And then it goes ahead and do the usual consistency checking etc.. I was ready for a long wait :)
Not too bad.. 11 hours !
