Userpaul Posted April 5, 2020 Share Posted April 5, 2020 (edited) Version: 6.7.2 Hi I'm curious about this element of the parity check and cannot see any obvious answers in the manual or here. Parity = 4tb Array 18 HDD Max HDD size excluding parity = 2TB Elapsed time: 21 hours, 49 minutes Current position: 3.45 TB (68.9 %) Estimated speed: 56.2 MB/sec Estimated finish: 7 hours, 41 minutes Sync errors corrected:0 All my hdd's except the parity spun down 15 hours into the parity check, the only hdd running is the parity. What is being checked? Thank you Edited April 5, 2020 by Userpaul solved Quote Link to comment

itimpi Posted April 5, 2020 Share Posted April 5, 2020 The parity check always runs to the full size of the parity disk regardless of the size of the data drives. This is why the time for a parity check is basically dependent on the size of the parity drive - not of the individual data drives in the array. As was mentioned this is to ensure that all of the parity drive beyond the size of the largest data drive contains zeroes so that you can later add larger data drives and keep parity valid Quote Link to comment
