1) Failover the cluster server. This doesn't help becuase same file is used by the nodes.
2) Drive has enough space. But is auto growth ON?
3) Created ndf file in different drive. But did you create it for the filegroup in question?
Are you sure it is 'DEFAULT' filegroup of 'TEMPDB'? Becuase TEMPDB has only one filegroup called 'PRIMARY'. You cannot add additional filegroup called 'DEFAULT' to TEMPDB. So how did you get that error message?
