I've been using mbralign 5.2.1 on an ESX 4.1 server with all datastores mounted via NFS from a NetApp 3240. </P><P></P><P>I was very interested in the NFS CopyOffLoad capabilities of the mbralign tool and got it working for the most part, however the nfs copyoffload feature seems to ignore the "--sparse" command line option. Is this normal operation or broken? </P><P></P><P>If I skip the copyoffload option and just go right to the NFS datastore and manually run mbralign with the --sparse option, it works as I'd expect it to, however this is a much slower process without the copyoffload feature. </P><P></P><P>Is there anyway to engage the nfs copyoffload feature and keep the vmdk files thin with the "--sparse" option? </P></BODY></HTML> Thu, 05 Jun 2025 06:15:23 GMT https://community.netapp.com/t5/VMware-Solutions-Discussions/mbralign-with-nfs-copyoffload-quot-sparse-quot-option-not-working-all-aligned/m-p/42941#M4208 itcambridge 2025-06-05T06:15:23Z Re: mbralign with nfs copyoffload: "--sparse" option not working, all aligned vmdk's are thick https://community.netapp.com/t5/VMware-Solutions-Discussions/mbralign-with-nfs-copyoffload-quot-sparse-quot-option-not-working-all-aligned/m-p/42946#M4209 <HTML><HEAD></HEAD><BODY><P>47 views and nothing?
