CIFS share space issue

[MSaleem]

NetApp C30 storage system with two nodes. Two aggregates have been created as per best practices, each with approximately 99.3 TB of usable capacity.

• Aggregate 1 hosts a CIFS/SMB FlexVol that is currently utilizing around 80 TB out of 99.3 TB.

• Aggregate 2 hosts an iSCSI volume that is utilizing approximately 10 TB out of 99.3 TB, leaving significant free capacity available.

The CIFS share is accessed by users via the mapped network path:
\\192.168.30.101\dxb_data\Data

All user data resides within a single qtree (without quotas), and the volume junction path is /DXB_DATA, Storage efficency is enable 

Due to capacity growth on Aggregate 1, I would like to utilize aggregate free capacity for existing CIFS shares.

The key requirement is to ensure that end users can continue accessing the HR folder using the existing mapped drive path, with no disruption to service and no changes required on the client side.

Hi, 

We created a while ago FlexGroup volumes that can be spanned across multiple aggregate. Now, you can convert a CIFS share from regular FlexVol to FlexGroup non disruptively.

I've just made a quick test in our Lab running aggressive file creation during the conversion and it did not fail nor freeze. 

FlexVol to FlexGroup conversion will allow data constituent addition that will allow volume expension beyond aggregate boundaries. A good practice is also to perform a rebalance after the data consituent addition to balance space consumption over the data constituent.
