示例1: checkResultBlockPool
/**
* For block pool, verify that the current and/or previous exist as indicated
* by the method parameters. If previous exists, verify that
* it hasn't been modified by comparing the checksum of all it's
* containing files with their original checksum. It is assumed that
* the server has recovered.
* @param baseDirs directories pointing to block pool storage
* @param bpid block pool Id
* @param currentShouldExist current directory exists under storage
* @param currentShouldExist previous directory exists under storage
