March 23, 20233 yr hi i googled today and did the script for unraid thats supposed to remove a drive from the array but it didnt work.. i moved all the files off.. created the folder clear-me and ran script kept saying there files when there wasnt it stated format the disk while in the array.. but it doesnt tell ya how to format it while online.. then there was the alternative.. you unmount the drive and then run the dd command... but it failed too ```root@Tardis:/# dd bs=1M if=/dev/zero of=/dev/md4 status=progress 2000323346432 bytes (2.0 TB, 1.8 TiB) copied, 14767 s, 135 MB/s dd: error writing '/dev/md4': No space left on device 1907730+0 records in 1907729+0 records out 2000398901248 bytes (2.0 TB, 1.8 TiB) copied, 14767.8 s, 135 MB/s``` i wanna removed my 2TB drive as i wanna use it for cctv.. but i have enough diskspace so i wanna shrink the array by the 2tb... what do i need to do that will work i was hoping unraid. had it built in.. so you stop array.. you choose the drive to remove from the array.. to no device and then restart the array and it rebuilds it without it but it didnt so not sure how i down size Edited March 23, 20233 yr by comet424

March 23, 20233 yr Author @Hoopster ok ill try reading that.. i did these steps but it didnt work at all Shrink array - Unraid | Docs https://wiki.unraid.net/Shrink_array
March 23, 20233 yr Author ok i re paritying least i got the drive removed.. just the save parity never worked..... go figure.. but least its pariting and array back online
March 23, 20233 yr I'm impressed! I think the normal situation is to put it off long enough that you eventually decide you need a bigger drive anyway. At least, that's what happened to me LOL
March 23, 20233 yr Author @ljm42well i have 27tb free well not 25tb free.. and i wanted to take out the 2TB drive as my others are all 12 and 14tb drives but i may have to add another 12 or 14tb i removed disk4 the 2tb drive well now it goes disk 1 2 3 5 6 7 lol guess i did something wrong i preserved it all as i feared if i do none i loose all my data i usually add a drive or replaced a drive never reduced a drive lol
March 23, 20233 yr I think if you did New Config -> Preserve All -> remove disk 4 -> rebuild parity (don't trust parity!) I think you are probably fine. But if anyone else sees an issue please speak up because as I said, I haven't actually done this myself.
March 23, 20233 yr Author @ljm42 ah i didnt see that when i did the new config there was just none all slots and all i chose all as i usually jsut replace a bad drive never downsized lol... learning moment lol excuse to buy another 12 or 14tb to shove in the disk 4 slot lol
March 23, 20233 yr Oh you should probably check your share settings and update any that still reference disk 4
March 23, 20233 yr Author @ljm42 i did check today when i tried to follow the instructions and run the script to shrink array article.. everything i have is reference the first 2 drives then let loose on the rest lol so i think im safe there?
