P\u00ebr diskutim n\u00eb list\u00ebn e d\u00ebrgimit t\u00eb zhvilluesve t\u00eb b\u00ebrtham\u00ebs Linux, jan\u00eb publikuar patch-e me implementimin e sistemit t\u00eb files BeamFS, i cili p\u00ebrdor kodimin e Raed-Solomoni p\u00ebr t\u00eb identifikuar dhe rikuperuar t\u00eb dh\u00ebnat e d\u00ebmtuara n\u00eb vend n\u00eb konfigurimet me nj\u00eb vet\u00ebm disk. Fushat kryesore t\u00eb p\u00ebrdorimit t\u00eb BeamFS p\u00ebrmenden si kompjuter\u00ebt e bordit t\u00eb satelit\u00ebve, pajisjet n\u00eb zyrat e terapi t\u00eb rrezatimit dhe sisteme t\u00eb tjera q\u00eb punojn\u00eb n\u00eb kushte t\u00eb rritura t\u00eb rrezatimit, p\u00ebr t\u00eb cilat rikthimi i t\u00eb dh\u00ebnave t\u00eb deformuara \u00ebsht\u00eb m\u00eb kritik se pamund\u00ebsia p\u00ebr t\u00eb lexuar informacionin.<\/p>\n

P\u00ebr default, BeamFS mund t\u00eb rikuperoj\u00eb deri n\u00eb 8 byte t\u00eb humbur n\u00eb \u00e7do blok prej 255 byte me shpenzime prej 7% (288 byte t\u00eb kodit t\u00eb rikuperimit p\u00ebr \u00e7do 4096 byte t\u00eb dh\u00ebnash t\u00eb ruajtura). Kodet e korrigjimit t\u00eb gabimeve aplikohen jo vet\u00ebm p\u00ebr t\u00eb dh\u00ebnat, por edhe p\u00ebr informacionin administrativ n\u00eb superblok, inode, indekset e dosjeve dhe hartat e bit\u00ebve. Kontrolli i integritetit dhe p\u00ebrpjekjet p\u00ebr rikuperimin e t\u00eb dh\u00ebnave t\u00eb munguara realizohen me \u00e7do operacion leximi. N\u00ebse nuk \u00ebsht\u00eb e mundur t\u00eb garantosh sakt\u00ebsin\u00eb e informacionit, operacioni p\u00ebrfundon me gabimin '-EIO', q\u00eb p\u00ebrjashton rikthimin e fshehur t\u00eb t\u00eb dh\u00ebnave t\u00eb d\u00ebmtuara. <\/p>\n

Eksperimentet e kryera treguan se gjat\u00eb rrezatimit t\u00eb bordit i.MX 8M Plus me Linux dhe FS ext4 nga protonet me energji nga 20 deri n\u00eb 58 MeV, 90% e t\u00eb gjitha defekteve ndodh\u00ebn n\u00eb nivelin e sistemit t\u00eb skedar\u00ebve dhe drejtor\u00ebve t\u00eb pajisjeve t\u00eb ruajtjes.

BeamFS siguron integritet dhe rikthim vet\u00ebm n\u00eb faz\u00ebn nga leximi nga burimi fizik deri n\u00eb transferimin n\u00eb memorizimin n\u00eb faqen n\u00eb memorien e operativ\u00ebs.

\nNga kufizimet e BeamFS p\u00ebrmendet mungesa e mb\u00ebshtetjes p\u00ebr regjistrimin dhe modin Copy-on-Write (CoW) - metadata n\u00eb disk shkruhen n\u00eb m\u00ebnyr\u00eb t\u00eb \u00e7rregullt, prandaj n\u00eb rast t\u00eb nj\u00eb p\u00ebrfundimi t\u00eb gabuar t\u00eb pun\u00ebs, k\u00ebrkohet nj\u00eb kontroll i plot\u00eb duke p\u00ebrdorur fsck.<\/p>\n
