Bjur Posted February 9 Share Posted February 9 Hi, I currently have 3 drives in my array (8 TB (parity), 6 TB and a 3 TB (both data)). I have bought 5 new and larger disks so I will be changing all of them. How do I do it the right way when all should be exchanged? Quote Link to comment
Frank1940 Posted February 9 Share Posted February 9 Personally, I would run a non-correcting parity check first to verify that all of the disks can be currently read. If that runs without an error, I would replace the parity disk and add the two new data disks. After parity rebuild and the formatting and clearing of the new disks, I would use the newly configured server for a month. This will verify that there are no infant mortality problems with the new disks. (You want to do this before the vendors return window expires! In fact, I would run another non-correcting parity check just before expiration....) Then replace one of the old data disks. Replace the second disk after a couple of weeks. (Store the old data disks for at least month after that. They are an emergency backup of your data!) (I am a bit paranoid and take more caution than many folks do but I worked in my prior life as a engineer and got my fingers burnt a few too many times when it was assumed that everything would go smoothly! In fact, one of things that I learned is that, if you planned for things not to go smoothly, any problems encountered were more easily corrected.) 1 Quote Link to comment
