Abstract: A file system layout apportions an underlying physical volume into one or more virtual volumes of a storage system. The virtual volumes having a file system and one or more files organized as buffer trees, the buffer trees utilizing indirect blocks to point to the data blocks. The indirect block at the level above the data blocks are grouped into compression groups that point to a set of physical volume block number (pvbn) block pointers.
