Kent Overstreet, sviluppatore di Bcachefs, ha annunciato il passaggio alla distribuzione di Bcachefs utilizzando gli strumenti DKMS (Dynamic Kernel Module Support), mediante i quali il modulo viene fornito nei sorgenti e compilato sul sistema dell'utente, immediatamente dopo l'installazione del pacchetto. Dopo un aggiornamento del kernel Linux, il modulo verr\u00e0 ricompilato automaticamente. <\/p>\n
La fornitura utilizzando DKMS permetter\u00e0 di non dover dipendere da ogni aggiornamento del kernel Linux, mantenendo l'implementazione di Bcachefs attuale, data la cessazione della ricezione di aggiornamenti per Bcachefs nel kernel principale. Le build sono pianificate per i principali distribuzioni Linux. Poich\u00e9 i moduli compilati tramite DKMS possono essere inclusi nell'initramfs, gli utenti manterranno la possibilit\u00e0 di utilizzare Bcachefs come filesystem radice. <\/p>\n
Si segnala separatamente che Kent ha discusso con i pacchetti core nei distribuiti Debian e openSUSE, che stavano per disabilitare la costruzione del kernel con supporto BCachefs. La disabilitazione era principalmente legata alla preoccupazione che BCachefs non sarebbe pi\u00f9 stato supportato, ma ora si sono accordati di temporeggiare con la disattivazione fino alla disponibilit\u00e0 dei pacchetti BCachefs basati su DKMS. Inoltre, il progetto \u00e8 vicino a rimuovere il riconoscimento del file system come sperimentale \u2014 dall'uscita del kernel 6.16, in BCachefs si sono manifestati solo bug insignificanti. <\/p>\n
Ricordiamo che in BCachefs \u00e8 stata fatta un tentativo di creare un file system che combini il livello di prestazioni, affidabilit\u00e0 e scalabilit\u00e0 di XFS con la funzionalit\u00e0 avanzata presente in Btrfs e ZFS. BCachefs supporta funzionalit\u00e0 come l'inclusione in una partizione di pi\u00f9 dispositivi, layout a strati degli archivi (strato inferiore con dati frequentemente utilizzati basato su SSD veloci, e strato superiore con dati meno richiesti da dischi rigidi), replica (RAID 1\/10), caching, compressione trasparente dei dati (modalit\u00e0 LZ4, gzip e ZSTD), istantanee di stato (snapshot), verifica dell'integrit\u00e0 con checksum, possibilit\u00e0 di archiviazione dei codici di correzione degli errori di Reed-Solomon (RAID 5\/6), archiviazione di informazioni in forma crittografata (vengono utilizzati ChaCha20 e Poly1305). In termini di prestazioni, BCachefs supera Btrfs e altri file system basati sul meccanismo Copy-on-Write, e dimostra velocit\u00e0 di operazione simile a Ext4 e XFS. \u041a\u0435\u043d\u0442
