June 29, 20215 yr Hello, I am in need of shrinking my array, is there any particular things i should know about going about this? I currently have a 24 disk array and i really only need the array to be 10 disk now. The 10 disks i care about house the data i need, the rest house data i do not need anymore so there's no "spread" of important data vs rubbish between the disks. If i remove a drive that i don't need, what is the best way for me to tell unraid to simply remove this disk and its parity information and just continue as is and not rebuild? I'm on unraid version 6.7.2 Thanks!
June 29, 20215 yr Author I see theres a good entry about shrinking array here: https://wiki.unraid.net/Shrink_array It may answer all my questions.
June 29, 20215 yr Since parity is calculated across all disks, you can't "just" have UNRAID remove parity info about one disk. If you don't need the disks, stop the array, do a new config, then add in the 10 disks you still need (they can be disk1 - disk10, no need to keep them in the same Disk# position they were in before), and let it rebuild parity. The only "non-parity-rebuild" option is to skip parity entirely. You'll then have 14 disks available to the Unassigned Devices plugin (assuming that's installed). Or, you can physically pull the drives. BTW- nice server names. Exactly the same as mine! Edited June 29, 20215 yr by FreeMan
