Ukukhishwa kwe-cluster FS Luster 2.13

eshicilelwe ukukhululwa kwesistimu yefayela le-cluster I-Luster 2.13, esetshenzisiwe kakhulu (~60%) enkulu kunazo zonke Amaqoqo e-Linux aqukethe amashumi ezinkulungwane zamanodi. I-scalability kumasistimu amakhulu kangaka ifinyelelwa nge-architecture enezingxenye eziningi. Izingxenye ezibalulekile zeLuster amaseva okucubungula imethadatha nokugcinwa (MDS), amaseva okuphatha (MGS), amaseva okugcina izinto (OSS), ukugcinwa kwento (OST, isekela elisebenza phezulu kwe-ext4 ne-ZFS) kanye namakhasimende.

main emisha:

• Kwenziwa inqolobane yohlangothi lweklayenti eqhubekayo (Inqolobane Yeklayenti Eqhubekayo), ekuvumela ukuthi usebenzise isitoreji sasendaweni, njenge-NVMe noma i-NVRAM, njengengxenye yendawo yegama ye-FS yomhlaba wonke. Amaklayenti angakwazi ukugcina idatha ehlotshaniswa namafayela asanda kwakhiwa noma akhona ohlelweni lwamafayela enqolobane afakwe endaweni (isb. ext4). Ngenkathi iklayenti lamanje lisebenza, lawa mafayela acutshungulwa endaweni ngesivinini se-FS yendawo, kodwa uma elinye iklayenti lizama ukufinyelela kuwo, athuthelwa ngokuzenzakalelayo ku-FS yomhlaba wonke.
• Kumarotha LNet kwenziwe ukutholwa okuzenzakalelayo kwemizila lapho usebenzisa umzila emigwaqweni embalwa ngokusebenzisa ukuxhumana kwenethiwekhi (I-Multi-Rail Routing) kanye nokwethenjelwa okukhuphukile kokucushwa okunama-node anokuxhumana okuningi kwenethiwekhi.
• Kwengezwe Imodi "ye-overstriping", lapho isitolo sezinto esisodwa (OST) singaqukatha amakhophi amaningana amabhlokhi emigqa yefayela elilodwa, okuvumela amaklayenti amaningana ukuba ngesikhathi esisodwa enze imisebenzi yokubhala ngokuhlanganyela efayelini ngaphandle kokulinda ukuthi ilokhi ikhishwe.
• Kuvele ukwesekwa izakhiwo zefayela ezizikhulisayo (Izakhiwo Ezizandisayo), okwandisa ukuguquguquka kokusebenzisa imodi ye-PFL (Izakhiwo Zefayela Eziqhubekayo) ezinhlelweni zamafayela ahlukahlukene. Isibonelo, lapho uhlelo lwefayela luhlanganisa amachibi okugcina amancane asekelwe ku-Flash drive esheshayo kanye namachibi amakhulu e-disk, isici esihlongozwayo sikuvumela ukuthi ubhalele kuma-storages asheshayo kuqala, futhi ngemva kokuba isikhala siphelile, shintsha ngokuzenzakalelayo kumachibi we-disk slow.
