Abstract
A system of volume health checking and recovery. The system comprises a health engine capable to check the health of a first volume that is a snapshot mirrored volume of a second volume; and a recovery engine, communicatively coupled to the health engine, capable to perform a recovery process if the first volume is unhealthy. Recovery can be performed via at least one of five methods.
Claims20
A method, comprising:
- providing a production volume and a first snapshot mirrored volume of the production volume;
- detecting the health of the first snapshot mirrored volume;
- determining the status of the production volume based on the detected health of the first snapshot mirrored volume;
- and
- performing a recovery process based on the determined status of the production volume.
2 more elements
A computer-readable medium storing instructions to cause a computer to perform a method, the method comprising:
- detecting the health of a first snapshot mirrored volume of a production volume;
- determining the status of the production volume based on the detected health of the first snapshot mirrored volume;
- and
- performing a recovery process based on the determined status of the production volume.
1 more element
A system, comprising:
- means for detecting the health of a snapshot mirrored volume of a production volume;
- means for determining the status of the production volume based on the detected health of the first snapshot mirrored volume;
- and
- means for performing a recovery process based on the determined status of the production volume.
1 more element
A system, comprising:
- a health engine operable to detect the health of a first snapshot mirrored volume of a production volume and to determine the status of the production volume based on the detected health of the first snapshot mirrored volume;
- and
- a recovery engine, communicatively coupled to the health engine, operable to perform a recovery process based on the determined status of the production volume.
A method for checking the health of a production volume, comprising:
- detecting the health of a snapshot mirrored volume of the production volume;
- determining the health of the production volume based on the detected health of the snapshot mirrored volume by checking the health of the snapshot minored volume as a representative for the production volume, thereby enabling reduced processing power demand on the production volume.
