May 24, 20251 yr Hi Everyone,i would kindly like to ask for your help on this issue i am struggling with. I have been operating my unraid for years, and i had no issues with drives spinning down. Without knowing when exactly this started i have really tried to find the reason why. I know i have the syslog process writing to disk 3 which i expect to wake up parity as well, however, all the rest of the disks should be spun down. When i spin down the disks, i see for example Disks 1 and 3 which i now they are used, but almost instantly the rest are spun up again, at the same time the syslog writes read SMART /dev/sdXYour insights would be really appreciated.nas-unraid-diagnostics-20250524-2356.zip Edited May 25, 20251 yr by NickI
May 25, 20251 yr Community Expert Solution You have turbo write enabled, any write to one array disk will spin up all other array disks.
May 25, 20251 yr Author Thank you so much i knew its something in front of my eyes that i couldn't see. Just for my personal reference, or anyone ever reaching into this topic, this is the topic that explains the Turbo Write perfectlyhttps://forums.unraid.net/topic/50397-turbo-write/
