I have a SQL 2008 R2 ENT database with the single [PRIMARY] filegroup, and a single FilestreamGroup. The filestream has millions of records, cannot be restored, and is about to exceed the drive space limit.
The table with the single filestream column has a primary key column that is also the Cluster index key. There is a Full Text index and several foreign key constraints to this table's primary key. All must be disabled prior to dropping and rebuilding the index for partitioning (tried and tested).
The filestream must be spread across multiple drive letters, and have multiple partitions on each drive, to facilitate file-restores within SLA. Due to its size, it may exceed the weekend maintenance window, and therefore must be done ONLINE to allow the business to save new documents while the rebuild is in operation.
How should I cobble this up into Filegroups / Files? A data filegroup per drive. What is Best Practice for the filestream?
