摘要： A system is provided for transforming an in-use RAID array from a first array configuration having a first parameter to a second array configuration having a second parameter while preserving a logical data structure of the RAID array. The system includes an extent reservation component, and a data migration component for reading unmigrated data from an area of an array arranged according to the first array configuration and writing the data to an area of the array arranged according to the second array configuration using reserved extents to store migrated data. The system also includes a first I/O component for performing I/O according to the first array configuration on unmigrated data prior to its reading by the data migration component, and a second I/O component for performing I/O according to the second array configuration on the migrated data after writing the migrated data.

摘要： Mechanisms for ensuring data consistency in a data store are provided. The mechanisms access a parity scrub factor f and perform a check on a data group of the data store. The check on the data group includes performing a parity check on a portion of the data group, the portion being equal to 1/f of the data group, and performing a data verify on the remainder of the data group. The performing of the check is repeated for the entire data store. An offset factor is used to select the portion of the data group for the parity check. In this case, the offset factor may be incremented when the performance of the check on the data group of the data store has been repeated for the entire data store.

摘要： A mechanism is provided for controlling a solid state disk. A failure detector detects a failure in the solid state disk. Responsive to failure detector detecting a failure, a status degrader sets a degraded status indicator for the solid state disk. Responsive to the degraded status indicator, a degraded status controller maintains the solid state disk in operation in a degraded operation mode.

摘要： Transforming an in-use RAID array from a first array configuration having a first parameter to a second array configuration having a second parameter while preserving the logical data structure. An extent reservation component and data migration component are provided for reading unmigrated data from an area of an array arranged according to the first array configuration and writing the data to an area of the array arranged according to the second array configuration using reserved extents to store first migrated data and using further extents to store second migrated data. A first I/O component for performing I/O according to the first array configuration on unmigrated data prior to its reading by the data migration component is provided along with a second I/O component for performing I/O according to the second array configuration on the first migrated data and the second migrated data after its writing by the data migration component.
