These are very small files (around 100-200 bytes) and the number of inodes needed depends on the number of NFS clients you are using in the environment. Small files, so smallest block size would make sense.</div>

<p> </p>
<p>I would like to use CES for exporting Samba and NFS. However, when reading the documentation (<a href="https://www.ibm.com/support/knowledgecenter/STXKQY_5.0.4/com.ibm.spectrum.scale.v5r04.doc/bl1adm_setcessharedroot.htm" id="LPlnk695968" previewremoved="true" target="_blank">https://www.ibm.com/support/knowledgecenter/STXKQY_5.0.4/com.ibm.spectrum.scale.v5r04.doc/bl1adm_setcessharedroot.htm</a>), is recommended (but not enforced) the use of a dedicated filesystem (of at least 4GB).</p>
<p> </p>
<p>Is there any best practice or recommendation for configuring this filesystem? This is: inode / block sizes, number of expected files in the filesystem, ideal size for this filesystem (from my understanding, 4GB should be enough, but I am not sure if there are conditions that would require a bigger one).</p>
<p> </p>
<p>Thanks a lot and best regards,</p>
<p>Marc </p>
