Protocols store some persistent data there. 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.

Generally these file systems are configured with a block size of 256KB. As for inodes I would not pre-allocate any and set the initial maximum size to value such as 5000 since it can be increased if necessary.

Subject: [EXTERNAL] [gpfsug-discuss] Dedicated filesystem for cesSharedRoot
Date: Thu, Jun 25, 2020 6:47 AM
Hi all,
I would like to use CES for exporting Samba and NFS. However, when reading the documentation (https://www.ibm.com/support/knowledgecenter/STXKQY_5.0.4/com.ibm.spectrum.scale.v5r04.doc/bl1adm_setcessharedroot.htm), is recommended (but not enforced) the use of a dedicated filesystem (of at least 4GB).
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).
Thanks a lot and best regards,
Marc
