Alexander Aring nga kompania Red Hat, q\u00eb mb\u00ebshtet n\u00ebnskemat IEEE 802.15.4, DLM dhe flock\/fcntl n\u00eb kernelin Linux, paraqiti n\u00eb list\u00ebn e shp\u00ebrndarjes p\u00ebr zhvilluesit e kernelit nj\u00eb sistem t\u00eb specializuar skedari DLMPFS. Sistemi i propozuar i skedar\u00ebve ofron nj\u00eb shtres\u00eb p\u00ebr bllokimet e skedar\u00ebve t\u00eb shp\u00ebrndar\u00eb t\u00eb realizuara nga DLM (Menaxheri i Bllokimit t\u00eb Shp\u00ebrndar\u00eb) dhe ramfs.

DLMPFS lejon pun\u00ebn me nj\u00eb hierarki skedar\u00ebsh t\u00eb p\u00ebrbashk\u00ebt p\u00ebr disa hote, krijimin dhe fshirjen e skedar\u00ebve dhe katalog\u00ebve, si dhe vendosjen ose heqjen e bllokimeve mbi skedar\u00ebt p\u00ebrmes funksioneve standarde flock() dhe fcntl(). N\u00eb t\u00eb nj\u00ebjt\u00ebn koh\u00eb, DLMPFS nuk lejon leximin dhe shkrimin e t\u00eb dh\u00ebnave nga skedar\u00ebt, duke u kufizuar vet\u00ebm n\u00eb operacionet me bllokime. Nj\u00eb kufizim tjet\u00ebr \u00ebsht\u00eb mund\u00ebsia p\u00ebr t\u00eb p\u00ebrcaktuar gjendjen e bllokimit vet\u00ebm duke e njohur plot\u00ebsisht rrug\u00ebn e skedarit t\u00eb bllokuar (DLM k\u00ebrkon emrin e burimit p\u00ebr t\u00eb p\u00ebrcaktuar bllokimin). <\/p>\n
Me DLMPFS mund t\u00eb adaptohen leht\u00ebsisht aplikacione ekzistuese q\u00eb varen nga vendosja e bllokimeve p\u00ebrmes API-ve flock\/fcntl, p\u00ebr t\u00eb p\u00ebrdorur bllokime t\u00eb shp\u00ebrndara q\u00eb mbulojn\u00eb disa hote n\u00eb kluster, pa pasur nevoj\u00eb p\u00ebr angazhim t\u00eb sistemeve t\u00eb specializuara t\u00eb skedar\u00ebve t\u00eb shp\u00ebrndar\u00eb p\u00ebr ruajtjen e t\u00eb dh\u00ebnave. <\/p>\n
DLMPFS dallohet nga skedari i ngjash\u00ebm DLMFS p\u00ebr shkak t\u00eb p\u00ebrdorimit t\u00eb API-ve flock\/fcntl n\u00eb vend t\u00eb API-ve specifike p\u00ebr skedar\u00ebt OCFS2.
