Linus Torvalds a aprobat cererea de includere a sistemului de fi\u0219iere Bcachefs \u00een kernelul principal Linux \u0219i a ad\u0103ugat implementarea Bcachefs \u00een repository-ul care dezvolt\u0103 ramura kernelului 6.7, al c\u0103rei release este a\u0219teptat la \u00eenceputul lunii ianuarie. Patch-ul ad\u0103ugat \u00een kernel con\u021bine aproximativ 95 de mii de linii de cod. Proiectul este dezvoltat de Kent Overstreet de mai bine de 10 ani, care a creat \u0219i sistemul de cache pentru discuri SSD Bcache inclus \u00een kernel. <\/p>\n

\u00cencerc\u0103rile de promovare a Bcachefs \u00een kernelul principal au \u00eenceput \u00een 2020, dup\u0103 care au fost necesare aproape trei ani pentru a remedia observa\u021biile \u0219i erorile identificate \u00een urma revizuirii. \u00cen prim\u0103vara acestui an a fost propus un set actualizat de patch-uri, care a fost respins de mai multe ori, dar, \u00een cele din urm\u0103, \u00een septembrie, a fost acceptat \u00een ramura linux-next, destinat\u0103 test\u0103rii func\u021bionalit\u0103\u021bilor pentru viitoarele versiuni ale kernelului Linux. <\/p>\n

Bcachefs se dezvolt\u0103 folosind tehnologii deja testate \u00een dezvoltarea dispozitivului de bloc Bcache, destinat pentru a permite accesul rapid la discuri rigide lente pe unit\u0103\u021bi SSD rapide (inclus \u00een kernel \u00eencep\u00e2nd cu versiunea 3.10). \u00cen Bcachefs se utilizeaz\u0103 mecanismul Copy-on-Write (COW), unde modific\u0103rile nu duc la suprascrierea datelor \u2014 noul stadiu este scris \u00eentr-un nou loc, dup\u0103 care se schimb\u0103 pointerul spre starea actual\u0103. <\/p>\n

\u00cen Bcachefs s-a f\u0103cut o \u00eencercare de a combina nivelul de performan\u021b\u0103, fiabilitate \u0219i scalabilitate caracteristic XFS, cu func\u021bionalit\u0103\u021bi extinse disponibile \u00een Btrfs \u0219i ZFS, cum ar fi includerea mai multor dispozitive \u00een parti\u021bii, aranjamente multilayer pentru unit\u0103\u021bi, replicare (RAID 1\/10), caching, comprimare transparent\u0103 a datelor (modurile LZ4, gzip \u0219i ZSTD), instantanee (snapshots), verificarea integrit\u0103\u021bii prin sume de control, capacitatea de a stoca coduri de corec\u021bie a erorilor Reed-Solomon (RAID 5\/6), \u0219i stocarea informa\u021biilor \u00een form\u0103 criptat\u0103 (se folosesc ChaCha20 \u0219i Poly1305). \u00cen ceea ce prive\u0219te performan\u021ba, Bcachefs dep\u0103\u0219e\u0219te Btrfs \u0219i alte FS bazate pe mecanismul Copy-on-Write \u0219i demonstreaz\u0103 o vitez\u0103 de operare apropiat\u0103 de Ext4 \u0219i XFS. <\/p>\n

O caracteristic\u0103 a Bcachefs este suportul pentru conectarea multilayer a unit\u0103\u021bilor, \u00een care stocarea este compus\u0103 din mai multe straturi \u2014 la stratul de baz\u0103 sunt conectate cele mai rapide unit\u0103\u021bi (SSD), care sunt utilizate pentru caching-ul datelor frecvent folosite, iar stratul superior este format din discuri mai mari \u0219i mai ieftine, care asigur\u0103 stocarea datelor mai pu\u021bin solicitate. \u00centre straturi poate fi aplicat caching \u00een modul de scriere \u00eent\u00e2rziat\u0103 (writeback). Unit\u0103\u021bile pot fi ad\u0103ugate \u0219i deconectate din parti\u021bie dinamic, f\u0103r\u0103 a opri utilizarea sistemului de fi\u0219iere (datele migreaz\u0103 automat).
