Abstract: A mechanism is provided in a data processing system for unobtrusive failover in a clustered file system. A node in the clustered file system periodically monitors publicized resource events from a cluster manager in the clustered file system for a triggering event that triggers a grace period. Responsive to detecting a triggering event, the node enters a grace period without restarting. During the grace period, the node processes a state request from a first client.

Other embodiments may be described and/or claimed.

Abstract: Client access prioritization is provided. A plurality of network addresses is assigned to a node of a network-attached storage cluster. A request to access a resource stored by the network-attached storage cluster and accessible to the node is received, wherein the request identifies a network address of the plurality of network addresses. A priority of the request is determined based, at least in part, on the network address identified by the request and further based, at least on part, on a protocol of the request. The request is processed based, at least in part, on the priority of the request.

Abstract: Mechanisms are provided for performing a write operation on a shared resource in a cluster of data processing systems. The mechanisms determine whether a locally cached copy of the shared resource is present in a local cache memory. The mechanisms, in response to a determination that a locally cached copy is present, determine whether the locally cached copy is a latest version of the shared resource. The mechanisms, in response to determining that that locally cached copy is a latest version: perform the write operation on the locally cached copy to generate an updated locally cached copy, and transmit a cluster event notification to other data processing systems of the cluster indicating the shared resource was written to and which data processing system performed the write operation. The cluster event notification is logged in at least one change log data structure associated with the other data processing systems.

Abstract: A scheme for monitoring node operational status according to communications transmits messages periodically according to a heartbeat rate among the nodes. The messages may be gossip messages containing the status of the other nodes in the pairs, are received at the nodes and indications of the communications delays of the received messages are stored, which are used to compute statistics of the stored communications delays. Parameters of the node status monitoring, which are used for determining operational status of the nodes, are adjusted according to the statistics, which may include adjusting the heartbeat rate, the maximum wait time before a message is considered missed, and/or the maximum number of missed messages, e.g., the sequence number deviation, before the node is considered non-operational (down).

Abstract: A computer-implemented method of managing lease transactions from a plurality of time-synchronized cluster nodes for a shared leased resource in a computer network, the method including accepting, during a request period, requests to lease a shared leased resource in an upcoming lease interval, the requests received from among a plurality of time-synchronized cluster nodes. The method may include selecting, during a response period which concludes prior to the beginning of the upcoming lease interval, a leaseholder for the shared leased resource in the upcoming lease interval in response to receiving at least one request during the request period, the leaseholder selected based on the at least one received request. The response period may occur after the request period. The method may include notifying, during the response period, the selected leaseholder of its selection as the leaseholder for the shared leased resource in the upcoming lease interval.

Abstract: An array of cross point memory cells comprises spaced elevationally inner first lines, spaced elevationally outer second lines which cross the first lines, and a multi-resistive state region elevationally between the first and second lines where such cross. Individual of the multi-resistive state regions comprise elevationally outer multi-resistive state material and elevationally inner multi-resistive state material that are electrically coupled to one another. The inner multi-resistive state material has opposing edges in a vertical cross-section. The outer multi-resistive state material has opposing edges in the vertical cross-section that are laterally offset relative to the opposing edges of the inner multi-resistive state material in the vertical cross-section. Methods are also disclosed.

Abstract: An event notification method for distributed processing systems provides reduction of queue space and event processing bandwidth associated with duplicate events such as a particular event that is duplicated and results in multiple event notifications propagated for multiple consumers. When a duplicate event notification is received at an input to an event notification queue, rather than queuing the duplicate event notification, a sequence number of the event notification already in the queue is updated to indicate to the event consumer, exactly how many duplicate events have been received. The timestamp of the updated event notification may also be set to the timestamp of the most recently received duplicate event notification.

The mechanisms, in response to determining that that locally cached copy is a latest version: perform the write operation on the locally cached copy to generate an updated locally cached copy, and transmit a cluster event notification to other data processing systems of the cluster indicating the shared resource was written to and which data processing system performed the write operation. The cluster event notification is logged in at least one change log data structure associated with the other data processing systems.

Abstract: A unique device name is assigned to each of a plurality of shared storage devices in a cluster configuration database defining membership of nodes in a cluster. A particular node among the nodes defined by the cluster configuration database as a member of the cluster searches the cluster configuration database for a device identifier matching a device identifier of a shared storage device hosted by the particular node. In response to finding a matching device identifier in the cluster configuration database, the particular node renames, in a local configuration maintained at the particular node, a storage device associated with the matching device identifier with the unique name assigned to that storage device in the cluster configuration database.

Abstract: Method for providing power to a passenger seat (10), whereby the passenger seats are individually fitted with removable fuel cells. The seat fitted with a fuel cell can then use fuel cell power, as well as the by-products generated by the fuel cell to supply energy and elements to optional seat functions. The method involves easily removing and replacing a fuel cell source/bottle associated with a passenger seat, such that even passengers can conduct the replacement, rather than crew members, which allows for fast and easy replacement, without any required tools or mechanical knowledge.
