Distributing data of multiple logically independent file systems in distributed storage systems including physically partitioned disks

A non-transitory computer readable storage medium including computer program instructions that, when executed, cause a computer processor to perform operations comprising:

• maintaining a plurality of logically independent file systems, wherein each file system includes a data set stored by a distributed storage;
• determining file system access pattern levels by observing accesses to data files in the data set included in each of the file systems;
• determining which file system is most frequently accessed among the plurality of logically independent file systems;
• establishing a dedicated physical partition in each of a plurality of disks for the data set of the most frequently accessed file system, the dedicated physical partition located near an outer edge of the respective disk;
• and distributing the data set of the most frequently accessed file system across dedicated physical partitions of the plurality of disks before distributing data sets of other file systems of the plurality of logically independent file systems across another partition in each of the plurality of disks, wherein the data sets of the other file systems are distributed based at least in part on determined file system access pattern levels for the plurality of logically independent file systems;
• determining that a specific file system from a plurality of other logically independent file systems has an access pattern level specifying a higher probability of future access than a probability of future access specified by an access pattern level of another one of the plurality of logically independent file systems;
• and
• redistributing a data set included in the specific file system prior to redistributing a data set included in another file system based on the determination that the specific file system from the plurality of other logically independent file systems has the access pattern level specifying a higher probability of future access than the probability of future access specified by the access pattern level of the another one of the plurality of logically independent file systems.

A system comprising:

• a hardware computer processor;
• and
• a non-transitory computer readable storage medium storing processor-executable computer program instructions, the instructions comprising instructions for:
• maintaining a plurality of logically independent file systems, wherein each file system includes a data set stored by a distributed storage;
• determining file system access pattern levels by observing accesses to data files in the data set included in each of the file systems;
• determining which file system is most frequently accessed among the plurality of logically independent file systems;
• establishing a dedicated physical partition in each of a plurality of disks for the data set of the most frequently accessed file system, the dedicated physical partition located near an outer edge of the respective disk;
• and
• distributing the data set of the most frequently accessed file system across the dedicated physical partitions of the plurality of disks before distributing the data sets of other file systems of the plurality of logically independent file systems across another partition in each of the plurality of disks, wherein the data sets of the other file systems are distributed based at least in part on determined file system access pattern levels for the plurality of logically independent file systems;
• determining that a specific file system from a plurality of other logically independent file systems has an access pattern level specifying a higher probability of future access than a probability of future access specified by an access pattern level of another one of the plurality of logically independent file systems;
• and
• redistributing a data set included in the specific file system prior to redistributing a data set included in another file system based on the determination that the specific file system from the plurality of other logically independent file systems has the access pattern level specifying a higher probability of future access than the probability of future access specified by the access pattern level of the another one of the plurality of logically independent file systems.
