Abstract
Data placement is adjusted. For instance, it is determined whether a node Failure To Tolerate (FTT) of a chunk in a storage system meets an optimized node FTT corresponding to the chunk, and, when it is determined that it does not meet, an FTT task entry for the chunk is added to a chunk index of the storage system. The added FTT task entry includes an identifier of the chunk, its node FTT, and the corresponding optimized system node FTT. Furthermore, instead of scanning placement information for each chunk, the storage system may adjust, based on the FTT task entry in the chunk index, placement of blocks of the corresponding chunk in system nodes. Therefore, the need to scan the placement information of all chunks and calculate their node FTTs in rebalance operations and minimum node FTT queries is eliminated, thereby improving the performance of the storage system.
