Luster Ngumthombo weFayile osasaziweyo osasaziweyo, ngesiqhelo isetyenziswe kumaqela amakhulu. Igama ngumxube weLinux kunye namaqela.
Le projekthi iinzame zokubonelela ngenkqubo yefayile yamaqela amashumi amawaka eendawo ezinee-petabytes zomthamo wokugcina, ngaphandle kwesantya okanye ukhuseleko, kwaye iyafumaneka phantsi kweGNU GPL.
IiNkqubo zeFayile yamaQela ngabayili, abaphuhlisi kunye nabagcini beLuster ngamagalelo avela kwezinye iinkampani nakubantu.
Malunga neLuster
Uninzi lweekhompyuter ezikhawulezayo kwihlabathi ziiklasta ezisebenzisa inkqubo yeLuster yokugcina, njengeenkqubo kwi-ORNL, PNNL, LLNL, nakwiLANL.
Le nkqubo ithathela ingqalelo ifayile nganye egcinwe kwifayile yeLuster kwifayile. ILuster yazisa bonke abathengi kwiPOSIX semantics esemgangathweni kunye nokufunda ngokufanayo kunye nokubhala ngokufanayo kwizinto ezabelwana ngazo. Inkqubo yefayile yeLuster ineeyunithi ezine ezisebenzayo.
Le iseva yedatha yeMeta (MDS) yokugcina imethadatha; ukujolisa kwento (OST) ukugcina eyona datha; umncedisi wokugcina into (i-OSS) yokulawula ii-OST; abathengi (ukufikelela) nokusebenzisa idatha.
Ii-OST zizixhobo zebhloko. I-MDS, i-OSS, kunye ne-OST inokuhlala kwindawo enye okanye kwiindawo ezahlukeneyo.
ILuster ayizilawuli ngokuthe ngqo ii-OST, kwaye ithumela olu xanduva kwii-OSS ukuqinisekisa ukwanda kwamaqela amakhulu kunye neekhompyuter.
Kwiprosesa yeMassively Parallell (MPP), abaqhubekekisi banokufikelela kwinkqubo yefayile yeLuster ngokudlulisela phambili izicelo zabo ze-I / O kwindawo kunye nenkonzo yokuqalisa umsebenzi ukuba iqulunqwe njengomthengi weLuster.
Nangona le yeyona ndlela ilula, ngokubanzi ibonelela ngokusebenza gwenxa. Indlela enzima ngakumbi yokubonelela ngokusebenza kakuhle kakhulu kukusebenzisa ilayibrari ye-libluster.
ILibluster yithala leencwadi elikwinqanaba lomsebenzisi elenza ukuba iiprosesa zikhuphuke kwaye zisebenzise inkqubo yefayile yeLuster njengomthengi, ngokudlula kulungelelwaniso lwendlela eya kuyo node yenkonzo.
Sebenzisa i-libluster, abaqhubekekisi banokufikelela kwifayile yeLuster, nokuba indawo yenkonzo apho umsebenzi wawusungulwe khona ayisiyiLuster client.
ILibluster ibonelela ngendlela yokuhambisa idatha ngokuthe ngqo phakathi kwendawo yesicelo kunye neeLuster OSSs ngaphandle kwesidingo sokwenza ikopi yedatha kwisiseko esingasindi, ngaloo ndlela kufezekiswa isantya esisezantsi, kunye nobubanzi bebhendi ekufikeleleni ngokuthe ngqo kweeprosesa kwinkqubo yefayile yeLuster.
Inguqulelo entsha yeLuster
Kungekudala Inguqulelo entsha yeLuster 2.12 yakhutshwa kunye neminye imisebenzi emitsha kwaye ngaphezulu kwako konke ukulungiswa kwe-bug kuye kongezwa Olunye ulwahlulo lweLinux olusetyenziselwa iikhompyuter ezinkulu.
Izinto eziphambili ezinqabileyo zeLuster 2.12
Ngale nkululeko intsha yongeze umsebenzi wokubeka isithuba kwizikhombisi ezinkulu ezikhoyo zesithuba segama (DNE, isasazelwe indawo yegama) ukusuka kwinto enye yokugcinwa kwemethadatha (i-DTM, iithagethi zemethadatha) ukuya kuninzi (ukwahlula amacandelo e-DNE ahlukeneyo zii-DTM ezahlukeneyo)
Inqaku elitsha lenza lula ukwaziswa kwee-MDTs ezintsha zee-FSs esele zikho kunye nokulinganisa kwakhona umthwalo kumthwalo kwi-MDT.
Kwimithombo yemethadatha (i-MDT), i "Lazy Size« imo iyenziwa, ekuvumela ukuba ubuyise ngokukhawuleza ubungakanani obuqikelelweyo endaweni yobungakanani beefayile xa uskena ngqo i-MDT ngenjini yomgaqo-nkqubo kwiimeko apho isantya sibaluleke ngakumbi Ukuchaneka.
Ukucwangciswa konxibelelwano lwe-LNet oluninzi, kule nguqulo intsha yeLuster 2.12 Umsebenzi we "LNet Network Health" wongezwa, ephumeza ukhetho lokufikelela kwakhona kwi-RPC ngolunye ujongano lwenethiwekhi kwimeko yokusilela okokuqala xa kuthunyelwa isicelo.
Ukongeza koku, inkxaso yeserver yongezwa kwiinguqulelo ze RHEL 7.6 (3.10.0-957.el7) kunye ne-SLES12 SP3 (4.4.162-94.69). Ukongezwa kwenkxaso yabathengi kwi-RHEL 7.6 (3.10.0-957.el7) engafakwanga, i-SLES12 SP3 (4.4.162-94.69) kunye ne-Ubuntu 18.04 (4.15.0-32).
