Abstract
A storage manager may initiate a merge operation for a set of writable storage volumes. The storage manager may receive, from a management server, an indication that an allocated disk space of at least one storage volume of the set of writable storage volumes is to be extended, where the at least one storage volume has exceeded a storage threshold during the merge operation. The allocated disk space of the at least one storage volume of the set of writable storage volumes may be extended in response to the received indication. The management server may be notified that the allocated disk space of the at least one storage volume has been extended upon extending the allocated disk space.
Claims20
A method comprising:
- initiating, by a processing device of a storage manager, a merge operation for a set of writable storage volumes;
- receiving, by the processing device of the storage manager from a management server connected to the storage manager via a network, an indication that an allocated disk space of at least one storage volume of the set of writable storage volumes is to be extended, wherein the at least one storage volume has exceeded a storage threshold during the merge operation;
- in response to receiving the indication, extending, by the processing device of the storage manager, the allocated disk space of the at least one storage volume of the set of writable storage volumes;
- and
- upon extending the allocated disk space of the at least one storage volume, notifying, by the processing device of the storage manager, the management server that the allocated disk space of the at least one storage volume has been extended.
A system comprising:
- a memory;
- and
- a processing device of a storage manager operatively coupled with the memory to:
- initiate a merge operation for a set of writable storage volumes;
- receive from a management server connected to the storage manager via a network, an indication that an allocated disk space of at least one storage volume of the set of writable storage volumes is to be extended, wherein the at least one storage volume has exceeded a storage threshold during the merge operation;
- in response to receiving the indication, extend the allocated disk space of the at least one storage volume of the set of writable storage volumes;
- and
- upon extending the allocated disk space of the at least one storage volume, notify the management server that the allocated disk space of the at least one storage volume has been extended.
A non-transitory machine-readable storage medium including instructions that, when executed by a processing device of a storage manager, cause the processing device to:
- initiate a merge operation for a set of writable storage volumes;
- receive, from a management server connected to the storage manager via a network, an indication that an allocated disk space of at least one storage volume of the set of writable storage volumes is to be extended, wherein the at least one storage volume has exceeded a storage threshold during the merge operation;
- in response to the received indication, extend the allocated disk space of the at least one storage volume of the set of writable storage volumes;
- and
- upon extending the allocated disk space of the at least one storage volume, notify the management server that the allocated disk space of the at least one storage volume has been extended.
