Multiple file system and/or multi-host single instance store techniques

One or more computing device readable media storing computing device executable instructions which when executed perform a method comprising:

• receiving one or more commands and one or more parameters to create a single instance store, a plurality of volumes, a cache object on top of a backing store of the single instance store, and one or more file systems, wherein the plurality of volumes comprises a plurality of thin volumes created on top of the cache object, and wherein blocks in the backing store are allocated in the plurality of thin volumes from the cache object;
• storing information creating the cache object and the plurality of volumes, including creating the plurality of thin volumes, in a volume manager configuration file, wherein the plurality of thin volumes allow the single instance store solution to be shared across a plurality of file systems, across a plurality of hosts or across a plurality of file system and a plurality of hosts;
• and
• storing information creating the one or more file systems in a file system configuration file, wherein each file system is created on top of the plurality of volumes including the plurality of thin volumes.

A storage system comprising:

• one or more processors coupled to one or more computing device readable media and executing computing device readable code stored in the one or more computing device readable media which implement one or more modules, wherein the one or more modules:
• receive one or more commands and one or more parameters to create a single instance store, a plurality of volumes, a cache object on top of a backing store of the single instance store, and one or more file systems, wherein the plurality of volumes comprises a plurality of thin volumes created on top of the cache object, and wherein blocks in the backing store are allocated in the plurality of thin volumes from the cache object;
• store information creating the cache object and the plurality of volumes, including creating the plurality of thin volumes, in a volume manager configuration file wherein the plurality of thin volumes allow the single instance store solution to be shared across a plurality of file systems, across a plurality of hosts or across a plurality of file system and a plurality of hosts;
• and
• store information creating the one or more file systems in a file system configuration file, wherein each file system is created on top of the plurality of volumes including the plurality of thin volumes.
