Red Hati ettev\u00f5tte Alexander Aring, kes toetab Linuxi tuumas IEEE 802.15.4, DLM ja flock\/fcntl alams\u00fcsteeme, esitles arendajate meililoendis spetsialiseeritud failis\u00fcsteemi DLMPFS. Soovitatud failis\u00fcsteem pakub kihti jaotatud faililukustuste jaoks, mis on rakendatud DLM-i (Distributed Lock Manager) ja ramfs-i baasil. DLMPFS-i rakendus on saadaval Linuxi tuuma 6.19 pat\u0161ide kogumina. <\/p>\n

DLMPFS v\u00f5imaldab t\u00f6\u00f6tada mitme hosti \u00fchise failihierarhiaga, luua ja kustutada faile ning katalooge, rakendada v\u00f5i eemaldada faililukustusi tavaliste funktsioonide flock() ja fcntl() abil. Samas ei v\u00f5imalda DLMPFS andmeid failidest kirjutada ja lugeda, piirduvad ainult lukustuste toimingutega. Piiranguks on ka see, et lukustuse olekut on v\u00f5imalik m\u00e4\u00e4rata ainult siis, kui tuntakse blokeeritava faili t\u00e4ispinef pathi (DLM n\u00f5uab ressurssi nime lukustuse m\u00e4\u00e4ramiseks). <\/p>\n

DLMPFS-i abil on lihtne kohandada olemasolevaid rakendusi, mis on seotud lukustuste m\u00e4\u00e4ramisega API flock\/fcntl kaudu, ja kasutada jaotatud lukustusi, mis katavad mitu hosti klastris, ilma et oleks vajalik kaasata spetsialiseeritud jaotatud failis\u00fcsteeme andmete salvestamiseks. <\/p>\n

DLMPFS erineb juba olemasolevast sarnasest failis\u00fcsteemist DLMFS, kasutades API-d flock\/fcntl, mitte OCFS2 failis\u00fcsteemi spetsiifilist API-d. Tulevikus plaanib DLMPFS lisada jaotatud lukustusi, mis on m\u00e4rgitud POSIX-i spetsifikatsioonis, ning v\u00f5imalust \u00fchendada erinevaid tagaplane, et integreerida mitte ainult DLM-iga, vaid ka teiste jaotatud lukustusteenustega, nagu NFS lockd. <\/p>\n

N\u00e4ide kasutamisest (teisel s\u00f5lmel t\u00fchistatakse failile \/mnt\/lock 20 sekundi p\u00e4rast): S\u00f5lm 1: mount -t dlmpfs -o clname=$CLUSTERNAME none \/mnt touch \/mnt\/lock flock \/mnt\/lock -c «echo ‘saadud’; sleep 20; echo ‘v\u00e4lja antud'» S\u00f5lm 2: mount -t dlmpfs -o clname=$CLUSTERNAME none \/mnt touch \/mnt\/lock flock \/mnt\/lock -c «echo ‘saadud’; sleep 20; echo ‘v\u00e4lja antud'»
