Hi I have a storage system that is under stress, and as luck has it I need to added more stress by loading it with a large cifs related volume, this is a transition from a 7-Mode ontap system
Every time we complete the transition, the system spikes disks 100%, cpu 100%, etc. On the perfstat we see deswizzling running. This is a normal operation every time a snapmirror break-off occurs, that is the deswizzle part of the equation.. When we take this volume offline, operations go back to normal.
My question, what is the result of disabling deswizzle is the short term, do I look functionality, e.g. vol move?
To turn off deswizzle: Nodeshell*> options wafl.deswizzle.enable off To turn on deswizzle: Nodeshell*> options wafl.deswizzle.enable on
Backround: FAS3210, C-Dot 8.2.3, SAS disks
