I have read this atricle:
https://www.ibm.com/support/knowledgecenter/en/STXKQY_4.2.0/com.ibm.spectrum.scale.v4r2.adv.doc/bl1adv_ces_migrationcnfstoces.htm

So, in a shortcut, CNFS cannot be used when sharing via CES.
I cannot use ganesha NFS.

Is it possible to share a cluster via SMB and NFS without using CES ?
the nfs will be expored via CNFS but what about SMB ? i cannot use
mmsmb..
