Avatud on OpenZFS 2.2.1 vaheversioon, mis arendab v\u00e4lja ZFS failis\u00fcsteemi rakendust Linuxi ja FreeBSD jaoks. V\u00e4ljaanne on t\u00e4helepanuv\u00e4\u00e4rne Linuxi tuuma 6.6 toe lisamise ning andmete kahjustamise probleemi (teatud blokkide nullimise) lahendamise katse t\u00f5ttu failides nende kopeerimise j\u00e4rel. <\/p>\n
Alguses arvati, et probleem ilmneb ainult 2.2.x harudes ja on tingitud veast OpenZFS 2.2.0-s sisalduvas plokkide kloonimise mehhanismis, mis v\u00f5imaldab luua faili v\u00f5i selle osa koopia, ilma andmete dubleerimise, kasutades teises koopias viiteid juba olemasolevatele andmeplokkidele algup\u00e4rasest failist, ilma nende tegelikku kopeerimist. OpenZFS 2.2.1-s on probleemi blokeerimiseks plokkide kloonimise mehhanism vaikimisi keelatud ning selle re\u017eiimi toetuse taastamiseks on lisatud seadistus zfs_bclone_enabled. <\/p>\n
Hiljem teavitasid arendajad, et probleem esines ka OpenZFS 2.1.x haru konfiguratsioonides. Ei kinnitunud ka eeldused, et probleem ilmneb vanade coreutils pakettide versioonidega s\u00fcsteemides \u2014 vea \u00f5nnestus reprodutseerida nii FreeBSD-s kui ka Linuxi jaotustes, kus on uusim coreutils 9.4 versioon. <\/p>\n
Failide kahjustumine ilmneb piisavalt harva esinevate asjaolude kokkusattumisel, n\u00e4iteks Gentoo-s k\u00e4ivitatud k\u00e4sk \u201eemerge -1 dev-lang\/go\u201d toob kaasa Go programmeerimiskeele t\u00f6\u00f6riistade installimise failide kahjustumisega kataloogis \/usr\/lib\/go\/pkg\/tool\/linux_amd64\/compile.
