mcdull Posted September 17, 2020 Share #1 Posted September 17, 2020 I have a VM under Proxmox running DSM 6.2 with AMD cpu. The DSM was migrated from an old intel with an SHR consists of 5 disks 3 x 8TB and 2 x 4TB Occassionally, the 2 4TB disk will be extremely busy with utilization at 99-100%, while the other 3 at 60-65% the 4TB disk are 7200 Toshiba, and the 8TBs are all helium based 5400rpm from WD. Are there any means that I can check what the 2 4TB are actually doing? I have scanned the 2 disks and without errors. Quote Link to comment Share on other sites More sharing options...
