Hi,  
I am using version 13.1.0-202102110202430875-3e6f3e7c of Dremio Community (cluster) but I have problems when I try to accelerate the reflections.  
The reflection stops shortly after the start and while the job shows it with the status ‘completed’ from the dataset settings the error appears: ‘Multiple trys to build Reflection failed, will not reattempt’, below are the screens:

Could this be a bug fixable with an upgrade?  
Specifically, the cluster does not use a shared ssd to save reflections.

Thanks for the support.

@amdanese Either the reflection had errors that the profile did not report or the load materialization job is incomplete, are you able to send us the profie of the refresh job and the server.log from the coordinator when the job failed?
