March 7, 201610 yr Helllo. I have 7 3 tb harddrives and one 250 gb, in an array. http://puu.sh/nyb7n/679b8d646b.png the parity is one of them, so six 3 tb data drives, one 250 gb one of the hard drives is failing and i want to replace it. the drive is empty except the small things unraid have put there. i want to replace the drive with a 2 tb drive. but when i do that it says "The replacement disk must be as big or bigger than the original" This confused me, as i was informed was that if you want to replace a drive it need to have capacity to hold all the data the old drive had, but not be the same size. is this wrong? can i not replace a 3 tb empty drive with a new 2tb? i would like to to the same with the 250 gb, but i need to replace the 3tb first since i can oly have one invalid drive a one time to start the array. thank you for all help, much appreciated!
March 7, 201610 yr No, you can't replace a drive with a smaller drive. If you want to downsize a drive, you can copy all of the data off of it to a safe location; then just do a New Config with a new, smaller drive, in place of the old one. This will, of course, invalidate parity, so the system will do a new parity sync when you Start the array.
March 7, 201610 yr Author The drive is empty, it does not have any important data on it. what do you mean by new config, more precise? i remove the old drive, put in the new, start and do a parity check? thank you for the quick reply
March 7, 201610 yr Author so i sorted it out. found the new config on tools, replaced the drives i needed to, and started the array. doing a parity check now. but it seems to work, all data on the other drives is there.
