Hi! I would like to know if it is possible to chose which drives that should be included in parity or have parity on a spesific share? Today I have two 3TB disks in my array and I'm not using parity because I don't store important files on my server at this time so capacity is priority. I do have two old 1tb drives laying around that I'm not using because they are too loud. I was thinking about adding them to the array for backing up my windows pcs at night and have the drives only spin up then. So is it possible to have one drive as backup with the other set to parity for the backup drive only?

No.  It is only possible to have parity protect the whole array, and the parity drive must be at least as large as the largest data drive.

You cannot do what you are asking, however you can accomplish the same thing by assigning both drives as cache drives. By default the cache pool will use RAID1, which in the case of 2 drives makes them duplicates, data wise.

 

 

Thank you so much for your replies. I forgot to mention that I already hava a 120GB SSD cache drive. So would it still be possible to do what jonathanm suggested?

Have the drives spin down after some period of time and there won't be any noise from them.  "Setting"  >>  "Disk Settings"  >>  Default spin down delay: [set time]

 

You can limit any share to single (or sub-set) of Drive(s).  "Shares"  >>  click on 'share' name  >>  "Share Settings"  Then use either (not both) 'Include Disk(s)' or 'Exclude Disk(s)'.      ("Help" on the tool bar is your friend!)  That way, you can largely prevent those noisy old 1Tb drives from spinning up and you will still have parity protection.
