Patent ID: 8028010

Claim:
A system for adjusting the size of an inline log for a file system without adjusting a size of a logical volume storing said inline log and said file system, comprising: a logical volume manager for managing allocation of a storage space into at least one logical volume for a file system of a particular size allocation wherein both an inline log for the file system and the file system are stored within a portion of said storage space of said particular size allocation allocated to said at least one logical volume; said logical volume manager for receiving a request to adjust an allocated size for said inline log for said file system within said storage space from a current size allocation to a new size allocation while maintaining said particular size allocation of said at least one logical volume; said logical volume manager, responsive to said request to adjust said allocated size for said inline log for said file system from said current size allocation to said new size allocation while maintaining said particular size allocation of said at least one logical volume, for shrinking a portion of a total storage space allocated to said file system within said logical volume and allocating additional storage space available from shrinking said portion of said total storage space allocated to said file system from within said logical volume to said inline log according to a storage space requirement for said new size allocation; and said logical volume manager for reformatting said inline log to said additional allocated storage space.
