Analysis of steady-state segment storage utilizations in a log-structured file system with least-utilized segment cleaning
John T. Robinson · ACM SIGOPS Operating Systems Review · 1996
The steady-state distribution of storage utilizations of segments in a log-structured file system with least-utilized (greedy) segment cleaning is found using analytic methods. Furthermore, it is shown that as the number of segments increases, this distribution approaches a limiting continuous distribution, which is also derived. These results could be useful for preliminary performance analysis of LFS-type system designs prior to the development of detailed simulation models or actual implementation.
