Abstract: A computer-implemented method, according to one embodiment, includes: receiving one or more suggestions which correspond to placement of data in storage. The one or more suggestions are used to identify portions of actual data stored in actual storage which correspond to the one or more suggestions. The first tier is configured to stripe data across the two or more shared nodes. For each of the identified portions of the actual data stored in the first tier, the one or more suggestions is further used to determine whether to transfer the given identified portion of the actual data to the second tier. Moreover, in response to a determination to transfer at least one of the identified portions of the actual data to the second tier, one or more instructions are sent to transfer the at least one of the identified portions of the actual data from the first tier to the second tier.

Abstract: A data storage system has multiple tiers of data storage including an upper tier having a lower access latency and a lower tier having a higher access latency. A storage controller of the data storage system receives, via an interface, an access request of a workload for a target file system object, where the target file system object has an associated temperature. In response to the access request for the target file system object, the storage controller accesses the target file system object in the data storage and conditions update of the associated temperature of the target file system object based on at least one of a set including the interface and the workload. The storage controller distributes a collection of file system objects including the target file system object among the multiple tiers based on respective heats of file system objects in the collection.

Abstract: A computer-implemented method, according to one embodiment, includes: receiving one or more suggestions which correspond to placement of data in storage, where the one or more suggestions are based on data workload characteristics. The one or more suggestions are used to identify portions of actual data stored in actual storage which correspond to the one or more suggestions. For each of the identified portions of the actual data stored in the first tier, the one or more suggestions is further used to determine whether to transfer the given identified portion of the actual data to the second tier. Moreover, in response to determining to transfer at least one of the identified portions of the actual data to the second tier, one or more instructions are sent to transfer the at least one of the identified portions of the actual data from the first tier to the second tier.

Abstract: Online file system consistency check for container data on a clustered file system is provided via identifying inodes (index nodes) of a group of files in a clustered file system based on a cyber-resiliency for the clustered file system; grouping the inodes based on a buffer size allocated to a FSCK (File System Consistency Check) operation; passing the inodes of to the FSCK operation in a single iteration when a total size of the inodes is less than the buffer size; or when the total size of the inodes is greater than the buffer size, identifying inodes that belong to a first container and that belong to a second container; passing the inodes that belong to the first container to the FSCK operation in a first iteration; and passing, after the first iteration completes, the inodes that belong to the second container to the FSCK operation in a second iteration.

Abstract: In an approach for optimizing clustered filesystem lock ordering in multi-gateway supported hybrid cloud environment, a processor identifies a wide area network (WAN) caching gateway topology between a set of nodes distributed in a hybrid cloud environment. A processor identifies a token request made for accessing a file targeted for WAN caching across sites within the hybrid cloud environment. A processor analyzes an importance of block ranges of the token request. A processor assigns a weight to the token request in relative comparison with weights allocated to token requests made by other applications. A processor dynamically modifies a read-ahead algorithm used during token generation to generate tokens for the block ranges of the token request based on the WAN caching gateway topology.

Abstract: A method for mitigating misinformation in encrypted messaging environments includes receiving content from an originating user, encrypting the content into an originating message using a first encrypting key, appending an originating message identifier to the originating message, storing the originating message identifier on a messaging server in conjunction with transmitting the originating message to a first device corresponding to a first recipient, decrypting the originating message using a first decrypting key, storing the content on the first device to produce locally stored content and inserting the originating message identifier within metadata for the locally stored content. The method may also include encrypting the locally stored content into a new message intended for a second recipient, detecting the originating message identifier within the metadata for the locally stored content, and appending the originating message identifier to the new message.

Abstract: A computer-implemented method, according to one embodiment, includes: receiving, at a clustered filesystem from a formatted filesystem, a request to perform a data integrity check for a portion of data. A determination is made as to whether the request includes a filesystem type of the portion of data, and in response to determining that the request includes a filesystem type of the portion of data, another determination is made as to whether the clustered filesystem supports the data integrity check for the filesystem type. In response to determining the clustered filesystem supports the data integrity check, another determination is made as to whether the portion of data is currently available. Furthermore, the computer-implemented method includes causing the data integrity check to be performed in response to determining that the portion of data is currently available. Results of performing the data integrity check are also sent to the formatted filesystem.

Abstract: A computer-implemented method according to one embodiment includes determining patterns of an application that utilizes a filesystem and/or properties of queries of the application. Data of the filesystem is stored across a plurality of replication sites of a data storage system. Based on the determined patterns of the application and/or the determined proper-ties of the queries of the application, a utility of storing at least some of the data of the filesystem in different variations at more than one of the replication sites is estimated. The estimated utility is compared against a predetermined utility threshold, and in response to a determination that the estimated utility is greater than the predetermined utility threshold, a write system call offered by the filesystem is modified to store the data in different variations at more than one of the replication sites.

Abstract: A plurality of computing nodes is monitored for updates to one or more files located on the plurality. Based on the monitoring, a first file operation is detected that is related to a first file located on a first node. The first file is related to a first copy that is located on a second node.

In response to the copy operation, a second copy file is created on the second computing node of the plurality. The second copy file is related to the second file located on the first computing node of the plurality.
