Error no 28 No space left on device with feature-classifier sklearn

I am having the same issue, running the cmd on a 16 cores 64gb RAM computer, and with plenty of space in each partition.

Here my cmd and error:

classifier …/…/reference_datasets/16S/silva-132-99-nb-classifier.qza --i-reads deblur/16S_repr_seq_deblur_run#2.qza --o-classification 16S_taxonomy2_run#2.qza
