Redmine Feature #1007 (Closed): Use dd for deployment of Linux imageshttps://code.grnet.gr/issues/10072011-08-04T19:00:52+03:00Vangelis Koukis
<p>Use <code>dd</code> to do sequential I/O with very large blocks for the deployment of Linux images.<br />This is the Linux version of <a href="https://code.grnet.gr/issues/965" class="issue status-6 priority-1 closed" title="Get rid of ntfsclone for deployment of Windows Images (Closed)">#965</a> and is closely related to <a href="https://code.grnet.gr/issues/969" class="issue status-6 priority-2 closed" title="Remove all-host based processing of (potentially user-provided) Images (Closed)">#969</a>: After the dd is done,<br />the OS provisioning process becomes a customization step, which modifies an existing filesystem.</p> Feature #965 (Closed): Get rid of ntfsclone for deployment of Windows Imageshttps://code.grnet.gr/issues/9652011-07-29T11:25:46+03:00Vangelis Koukis
<p>ntfsclone is FUSE-based, inefficient (does I/O in 4kB chunks), causes huge spikes in I/O and even CPU load.<br />Investigate if it's possible to get rid of it completely, and replace it with a dd-based solution or something similar.</p>
<p>Also investigate whether resizing the resulting NTFS can be done from inside the VM with Microsoft code, in the SYSPREP phase,<br />so that <code>ntfsresize</code> can go too.</p>
