FAS2240 Storage Efficiency Not enough disk space for the operation

[MatthewS]

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%.

Hi,

Which version of ONTAP are you using?

Thanks

[MatthewS]

NetApp Release 8.1.2 7-Mode

There is a bug mentioned in the KB Article https://kb.netapp.com/support/index?page=content&id=7010056

I am having an issue running the cleanup.

netapp2> sis start -s /vol/plm_vol2
The file system will be scanned to process existing data in /vol/plm_vol2.
This operation may initialize related existing metafiles.
Are you sure you want to proceed (y/n)? y
The SIS operation for "/vol/plm_vol2" is started.

Wed Dec 17 10:06:21 EST [netapp2:sis.op.aborted:error]: SIS operation for /vol/plm_vol2 has aborted: Not enough disk space for the operation

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.
