Alexander Aring nga kompania Red Hat, i cili mb\u00ebshtet n\u00ebn\u00ebsistemat IEEE 802.15.4, DLM dhe flock\/fcntl n\u00eb b\u00ebrtham\u00ebn Linux, paraqiti n\u00eb list\u00ebn e email-it t\u00eb zhvilluesve t\u00eb b\u00ebrtham\u00ebs nj\u00eb sistem t\u00eb specializuar skedar\u00ebsh DLMPFS. Sistemi i propozuar ofron nj\u00eb shtres\u00eb p\u00ebr bllokimet e skedar\u00ebve t\u00eb shp\u00ebrndara, t\u00eb realizuara bazuar n\u00eb DLM (Menaxheri i Bllokimeve t\u00eb Shp\u00ebrndara) dhe ramfs.

DLMPFS lejon pun\u00ebn me nj\u00eb hierarki skedar\u00ebsh t\u00eb p\u00ebrbashk\u00ebt p\u00ebr disa hoste, t\u00eb krijoni dhe fshini skedar\u00eb dhe katalog\u00eb, si dhe t\u00eb vendosni ose hiqni bllokimet p\u00ebr skedar\u00ebt duke p\u00ebrdorur funksionet standarde flock() dhe fcntl(). Megjithat\u00eb, DLMPFS nuk lejon t\u00eb shkruani dhe t\u00eb lexoni t\u00eb dh\u00ebna nga skedar\u00ebt, duke u kufizuar vet\u00ebm n\u00eb operacionet me bllokime.

DLMPFS dallon nga sistemi i ngjash\u00ebm ekzistues DLMFS duke p\u00ebrdorur API'n flock\/fcntl n\u00eb vend t\u00eb API's specifike p\u00ebr sistemet e skedar\u00ebve OCFS2.
