Microsoft Cluster File Share Witness on Isilon share?


Is anyone using an Isilon CIFS share for a Microsoft Cluster File Share Witness quorum share?  We are on OneFS  We use CIFS shares on our Isilon cluster as File Share Witness for a number of our Microsoft SQL clusters.  We have seen intermittent failures with the FSW (errors 1564, 1069, 1562).

The following white-paper is pretty old.  They do not recommend using SMB3-CA which we have not enabled in our case.  Also hasn't been updated in a while.  Other folks appear to have similar issues with instability.

Wondering if anyone has been able to get a Microsoft FSW to work reliably.
