Abstract: An system for quota arbitration of a distributed file system (DFS) may obtain a current amount of storage used by a given quota entity on storage segments of the DFS, the given quota entity having a global quota for the DFS and each of the storage segments being assigned a respective first quota limit for the given quota entity. The system may determine a global available quota amount for the given quota entity across all the storage segments based on the obtained current amounts of storage used by the given quota entity and the global quota, and provision of a respective second quota limit for the given quota entity to each of the plurality of storage segments, based on a division of all or less than all of the global available quota amount.

Abstract: Examples include quota arbitration of a distributed file system (DFS). Some examples obtain a current amount of storage used by a given quota entity on storage segments of the DFS, the given quota entity having a global quota for the DFS and each of the storage segments being assigned a respective first quota limit for the given quota entity. Some examples include determination of a global available quota amount for the given quota entity across all the storage segments based on the obtained current amounts of storage used by the given quota entity and the global quota, and provision of a respective second quota limit for the given quota entity to each of the plurality of storage segments, based on a division of all or less than all of the global available quota amount.

Abstract: Examples include, in response to fulfilment of a tiering policy, dividing, by a cloud provider engine of a computing device, data blocks of a filesystem object into data chunks. Some examples comprise generating, by the cloud provider engine, a current manifest file in a local memory and causing the cloud storage system to generate a current pseudo folder in the cloud storage system corresponding to a particular epoch of the filesystem object. Some other examples comprise tiering, by the cloud provider engine, the data chunks and the current manifest file to the current pseudo folder, the current manifest including pointers to the data chunks corresponding to the filesystem object at the particular epoch.
