Zotsatira za mayeso a Reiser5 file system zidasindikizidwa

Zotsatira za mayeso a magwiridwe antchito a projekiti ya Reiser5 zasindikizidwa, zomwe zimapanga mtundu wosinthidwanso kwambiri wa fayilo ya Reiser4 mothandizidwa ndi ma voliyumu omveka omwe ali ndi "makulitsidwe ofanana", omwe, mosiyana ndi RAID yachikhalidwe, amatanthauza kutenga nawo gawo mwachangu pamafayilo. pogawa deta pakati pa zida zamagulu a voliyumu yomveka. Kuchokera pakuwona kwa woyang'anira, kusiyana kwakukulu kuchokera ku RAID ndikuti zigawo za voliyumu yofananira ndi zida zojambulidwa.

Zotsatira za mayeso zomwe zaperekedwa zimawunika momwe mafayilo amagwiritsidwira ntchito wamba, monga kulemba fayilo mpaka voliyumu yomveka, kuwerenga fayilo kuchokera pa voliyumu yomveka yopangidwa ndi kuchuluka kosinthika kwa ma drive olimba. Kugwira ntchito pama voliyumu omveka, monga kuwonjezera chipangizo pa voliyumu yomveka, kuchotsa chipangizo pa voliyumu yomveka, kubwezeretsanso deta kuchokera ku ma proxy disks, ndi kusamutsa deta kuchokera ku fayilo yokhazikika (osati yapadera) kupita ku chipangizo china, kunalinso. kuyeza.

Ma Solid-state drives (SSD) mu kuchuluka kwa makope 4 adagwiritsidwa ntchito kusonkhanitsa ma voliyumu. Kuthamanga kwa opareshoni pa voliyumu yomveka kumatanthauzidwa ngati chiŵerengero cha kuchuluka kwa malo okhala pa voliyumu yonse yomveka mpaka nthawi yomwe imafunika kuti amalize ntchitoyi, kuphatikizapo kugwirizanitsa kwathunthu ndi zoyendetsa.

Kuthamanga kwa ntchito iliyonse (kupatulapo kuthamangitsa deta kuchokera ku diski ya proxy pa voliyumu yopangidwa ndi zipangizo zochepa) ndipamwamba kuposa kuthamanga kwa kukopera deta kuchokera ku chipangizo china kupita ku china. Panthawi imodzimodziyo, ndi kuwonjezeka kwa chiwerengero cha zipangizo zomwe voliyumu imapangidwira, kuthamanga kwa ntchito kumawonjezeka. Kupatulapo ndi ntchito yosuntha mafayilo, kuthamanga kwake komwe kumayandikira (kuchokera pamwamba) liwiro lolembera ku chipangizo chandamale. Kufikira motsatizana motsika: Chipangizo Chowerengera, M/s Lembani, M/s DEV1 470 390 DEV2 530 420 Fayilo yayikulu yotsatizana kuwerenga/lemba (M/s): Chiwerengero cha ma disks mu voliyumu Lembani Werengani 1 (DEV1) 380 460 1 ( DEV2) 410 518 2 (DEV1+DEV2) 695 744 3 (DEV1+DEV2+DEV3) 890 970 4 (DEV1+DEV2+DEV3+DEV4) 950 1100 Kukopera kwachinsinsi kwa deta kuchokera/ku chipangizo chopangidwa ndi Speed ​​​​Ku chipangizo Ku chipangizo Ku chipangizo (M/s) DEV1 DEV2 260 DEV2 DEV1 255 Kuwonjezera chipangizo ku voliyumu yomveka: Voliyumu Chipangizo chiyenera kuwonjezeredwa Speed ​​​​(M/s) DEV1 DEV2 284 DEV1+DEV2 DEV3 457 DEV1+DEV2+DEV3 DEV4 574 Kuchotsa chipangizo kuchokera mu voliyumu yomveka: Chida cha Volume chiyenera kuchotsedwa Speed ​​​​(M/s) DEV1+DEV2+DEV3+DEV4 DEV4 890 DEV1+DEV2+DEV3 DEV3 606 DEV1+DEV2 DEV2 336 Bwezeretsani deta kuchokera ku proxy disk: Volume Proxy disk Speed ​​​​(M/s) DEV1 DEV4 228 DEV1+DEV2 DEV4 244 DEV1+DEV2+ DEV3 DEV4 290 DEV1 RAM0 283 DEV1+DEV2 RAM0 301 DEV1+DEV2+DEV3 RAM0 374 DEV1+DEV2ration3+DEV4+DE File Target+DEV0+DE (M/s) DEV427+DEV1+DEV2+DEV3 DEV4 1 DEV387+DEV1 +DEV2 DEV3 1 DEV403+DEV1 DEV2 1

Zimadziwika kuti magwiridwe antchito atha kupitilizidwanso ngati njira yoperekera zopempha za I/O ifananizidwa ndi zigawo zonse za voliyumu yomveka (pakali pano, kuti zikhale zosavuta, izi zimachitika mu lupu ndi ulusi umodzi). Komanso ngati muwerenga zidziwitso zokhazo zomwe zimatha kusuntha panthawi yokonzanso (tsopano, kuti zikhale zosavuta, deta yonse imawerengedwa). Malire ongoyerekeza a liwiro lowonjezera / kuchotsa chipangizo chachiwiri m'makina omwe ali ndi makulitsidwe ofananira ndi liwiro lambiri kuchokera pa diski yoyamba kupita yachiwiri (motsatira, kuchokera pachiwiri mpaka woyamba). Tsopano kuthamanga kwa kuwonjezera ndi kuchotsa disk yachiwiri ndi 1.1 ndi 1.3 kukopera liwiro.

Kuonjezera apo, O (1) defragmenter adalengezedwa kuti adzakonza zigawo zonse za voliyumu yomveka (kuphatikizapo disk proxy) mofanana, i.e. mu nthawi yosapitirira nthawi yokonza gawo lalikulu padera.
