Abstract

A method and device for managing sessions comprises obtaining first identification information of a first session of a plurality of sessions and group operation identification information of a group operation to be performed for the plurality of sessions, each of the plurality of sessions replicating, from a source of the session to a destination of the session, a file system or a management system that manages the file system; determining whether the first session meets a condition that a session is suitable to be selected as a managing session, the managing session managing the plurality of sessions to perform the group operation on the plurality of sessions; in response to the first session failing to meet the condition, obtaining second identification information of a second session of the plurality of sessions, the second identification information being different from the first identification information; and selecting the managing session based on the second identification information.

Claims16

Dependent claims

A method of managing sessions, comprising:

obtaining first identification information of a first session of a plurality of sessions and group operation identification information of a group operation to be performed for the plurality of sessions, each of the plurality of sessions replicating, from a source of the session to a destination of the session, a file system or a management system that manages the file system;
determining whether the first session meets a condition that a session is suitable to be selected as a managing session, the managing session managing the plurality of sessions to perform the group operation on the plurality of sessions, wherein determining whether the first session meets the condition includes:
obtaining a state of the first session based on the first session identification information;
determining whether the state indicates that the first session is in failover;
determining whether the destination of the first session is a site at which the group operation was initiated;
in response to determining that the state indicates that the first session is not in failover and determining that the destination of the first session is a site at which the group operation was initiated, determining that the first session meets the condition;
and
otherwise, determining that the first session does not meet the condition;
in response to the first session failing to meet the condition, obtaining second identification information of a second session of the plurality of sessions, the second identification information being different from the first identification information;
and
selecting the managing session based on the second identification information.

A device for managing replication sessions, comprising:

at least one processing unit;
at least one memory coupled to the at least one processing unit and having stored thereon instructions executed by the at least one processing unit, the instructions, when executed by the at least one processing unit, causing the device to perform actions comprising:
obtaining first identification information of a first replication session of a plurality of replication sessions and group operation identification information of a group operation to be performed for the plurality of replication sessions, each of the plurality of replication sessions replicating, from a source of the replication session to a destination of the replication session, a file system or a management system that manages the file system;
determining whether the first replication session meets a condition that a replication session is suitable to be selected as a managing session, the managing session managing the plurality of replication sessions to perform the group operation on the plurality of replication sessions, wherein determining whether the first replication session meets the condition includes:
obtaining a state of the first replication session based on the first session identification information;
determining whether the state indicates that the first replication session is in failover;
determining whether the destination of the first replication session is a site at which the group operation was initiated;
in response to determining that the state indicates that the first replication session is not in failover and determining that the destination of the first session is a site at which the group operation was initiated, determining that the first replication session meets the condition;
and
otherwise, determining that the first replication session does not meet the condition;
in response to the first replication session meeting the condition, selecting the first replication session as the managing session;
and
in response to the first replication session failing to meet the condition, obtaining second identification information of a second replication session of the plurality of sessions, the second identification information being different from the first identification information, and selecting the managing session based on the second identification information.

A computer program product for managing replication sessions, the computer program product comprising:

a non-transitory computer readable medium encoded with computer-executable code, the code configured for the execution of:
obtaining first identification information of a first replication session of a plurality of replication sessions and group operation identification information of a group operation to be performed for the plurality of replication sessions, each of the plurality of replication sessions replicating, from a source of the replication session to a destination of the replication session, a file system or a management system that manages the file system;
determining whether the first replication session meets a condition that a replication session is suitable to be selected as a managing session, the managing session managing the plurality of replication sessions to perform the group operation on the plurality of replication sessions, wherein determining whether the first replication session meets the condition includes:
obtaining a state of the first replication session based on the first session identification information;
determining whether the state indicates that the first replication session is in failover;
determining whether the destination of the first replication session is a site at which the group operation was initiated;
in response to determining that the state indicates that the first replication session is not in failover and determining that the destination of the first session is a site at which the group operation was initiated, determining that the first replication session meets the condition;
and
otherwise, determining that the first replication session does not meet the condition;
in response to the first session meeting the condition, selecting the first session as the managing session;
and
in response to the first replication session failing to meet the condition, obtaining second identification information of a second replication session of the plurality of replication sessions, the second identification information being different from the first identification information, and selecting the managing session based on the second identification information.
