hidroela Posted November 21, 2015 #1 Posted November 21, 2015 hi guys i just try to add a new hard drive to increase the size of volumes 2 that was getting full, but after adding a 3TB HDD) this is what storage manager show.
MaZeeT Posted November 21, 2015 #2 Posted November 21, 2015 Hey Hidroela.. it is because of your raid settings.. Raid 1 is a mirror of the drives, so you will get the space of the smallest of the two drives which is 1TB... since it is a mirror you will get Volume of 1TB with 1TB backup from your 3TB drive and 2TB lost space.. If I remember right you will be able to map the remaining 2TB to a 2nd volume... I would suggest you make a Volume on the 3TB drive of 3TB and a second volume of 1TB on the 1TB drive.. It all depend on what you want to do with the volume... If you aren't sure what the different raids do and the pros and cons. I will suggest you to read up on it.. Synology have a good calculator if you want to try out different configurations. https://www.synology.com/en-us/support/RAID_calculator
hidroela Posted November 21, 2015 Author #3 Posted November 21, 2015 thanks let try and do what you say, make a volume of the 3tb
manfriday Posted November 23, 2015 #4 Posted November 23, 2015 Bare in mind the limitations of the RAID calculator. It allows configurations that will not work for you. E.G. you start with 1TB and add 3TB then add 2TB, the calc gives you the math results but if you try it for real you will have the added 2TB disk all by itself whether you use SHR or RAID
