Adding Disk, Creating a LUN on Autoraid 12H

I add a additional 36 GB disk to the autoraid.
allocated for LUN are 49 GB
used for redundancy 42 GB
unallocated 13 GB

whem i a trying to add a lun with 32 GB
# arraycfg -L 6 -a 32G $RID
i get the error: Not enough space to create lun

How can i downsize the diskspace used for redundancy to create an LUN with 32G?

Thanks,
Richard

If you understand the risks, you can disable active hot spare.
If it ain't broke, I can fix that.

The only way that you can do for extra disk space is to disable global hot spare if it's enabled.
Global Hot spare provides additional protection against the failure of a single disk.
Please bear in mind that you will lose whole data in the array if you have a second disk failure with hot spare disabled because data is striped across all disks in the AutoRAID.

Hopt this helps,
