FAS2240 Storage Efficiency Not enough disk space for the operation

MatthewS — Thu, 05 Jun 2025 05:22:32 GMT

Deduplication is not running on my volume and gives an error "Not enough disk space for the operation". The volume is 7.4TB with 1.8TB of available space. I have a single lun with thin provisioning that is set to 8TB with 146.74GB free. My deduplication savings is 2.93TB. Why is my storage efficiency/deduplication not working now? I was told before that I only needed to make sure I had around 10% free space on the volume which I have around 24%.

I am having an issue running the cleanup.

It looks like my aggregate is full. How can I fix this? I worked with a netapp engineer to set this up so I would not have to constantly monitor this but it looks like it must not of been configured correctly or a software bug got me.

I think it will be better to open a case with the support center to look in to this issue in detail.

I opened a case and then came into work and it went from 0GB free to 900GB. I am now able to run the sis start -s /vol/plm_vol2

Thanks for you help.
