Description
  • Mnoho zátěží na pevném disku mění pouze malé množství bloků. Souborový systém organizovaný jako zápisník byl vyvinut právě pro tento druh zátěže, navíc s možností zotavení z havárie a obnovu obrazu systému. Překvapivě, ačkoli již byl implementován pro Sun Sprite a BSD, stále nebyl tento souborový systém uveden pro aktuální systémy Linux. V tomto článku popisujeme novou kompletní implementaci spolu s uklízením nepoužité paměti z uživatelského prostoru. Zhodnocujeme také výsledky pokusných měření a porovnáváme je s rozšířeným souborovým systémem ext3. (cs)
  • In many workloads, most write operations performed on a file system modify only a small number of blocks. The log-structured file system was designed for such a workload, additionally with the aim of fast crash recovery and system snapshots. Surprisingly, although implemented for Sun Sprite and BSD systems, there was no complete implementation for the current Linux kernel. In this paper, we present a complete implementation of the log-structured file system for the Linux kernel, which includes a user-space garbage collector and additional tools. We evaluate the measurements obtained in several test cases and compare the results with widely-used ext3.
