Abstract
A processing device receives a request from a remote computing device to read data from a virtual storage device. The processing device identifies a physical storage device to be accessed to satisfy the request. The processing device then sends a sub-request to the physical storage device to access a portion of the physical storage device. Responsive to determining that the physical storage device has not returned a response to the sub-request within a latency threshold time associated with the physical storage device, the processing device initiates recovery of the portion of the physical storage device to recompute contents of the portion of the physical storage device. The processing device then returns a response to the request from the remote computing device.
