Stable-Storage Implementation in Operating system By definition, information residing in the Stable-Storage is never lost. Even, if the disk and CPU have some errors, it will never lose any data. Stable-Storage Implementation : To achieve such storage, we need to replicate the required information on multiple storage devices with independent failure modes. The writing of an update should be coordinate in such a way that it would not delete all the copies of the state and that, when we are recovering from a failure, we can force all the copies to a consistent and correct value, even if another failure occurs during the recovery. In these, we discuss how to meet these needs. The disk write operation results to one of the following outcome: Successful completion – The data will written correctly on disk. Partial Failure – In this case, failure is occurred in the middle of the data transfer, so that only some sectors were written with the new data, and the s...
