2 out of 5 drives in SHR being very busy


Recommended Posts

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.
