+Is this remote configured with chunk? (`git-annex info
+s3_dssi-bioinfo-shlyakhi_sccrispr-data`)
+
+Either chunk or partsize should work. partsize is disabled by default
+because there are a lot of S3 implementations besides AWS, that may not
+support it.
+
+Generally, it's probably better to use partsize rather than chunk if the S3
+server supports it.
