LINUX Unplugged - A podcast by Jupiter Broadcasting - Mondays

Categories:

Kent Overstreet, the creator of bcachefs, helps us understand where his new filesystem fits, what it's like to upstream a new filesystem, and how they've solved the RAID write hole.Special Guest: Kent Overstreet.Sponsored By:Tailscale: Tailscale is a programmable networking software that is private and secure by default - get it free on up to 100 devices!Kolide: Kolide is a device trust solution for companies with Okta, and they ensure that if a device isn’t trusted and secure, it can’t log into your cloud apps.Support LINUX UnpluggedLinks:πŸ’₯ Gets Sats Quick and Easy with Strike πŸ“» LINUX Unplugged on Fountain.FM Boltz β€” Privacy First, Non-Custodial Bitcoin Exchange.bcachefs β€” bcachefs is an advanced new filesystem for Linux, with an emphasis on reliability and robustness and the complete set of features one would expect from a modern filesystem. bcachefs Erasure coding β€” Bcachefs takes advantage of the fact that it is already a copy-on-write filesystem. If we're designing our filesystem to avoid update-in-place, why would we do update-in-place in our RAID implementation?bcachefs Caching β€” bcachefs can be configured for writethrough, writeback, and writearound caching, as well as other more specialized setups. bachefs Compression β€” Unlike other filesystems that typically do compression at the block level, bcachefs does compression at the extent level - variable size chunks, up to (by default) 128k.bcachefs Encryption β€” bcachefs uses AEAD style encryption (ChaCha20/Poly1305), where each encrypted block is authenticated with a MAC, with a chain of trust up to root (the superblock), and every encrypted block has a unique nonce. bcachefs Snapshots β€” bcachefs provides Btrfs style writeable snapshots, at subvolume granularity. (2015) [ANNOUNCE] bcachefs - a general purpose COW filesystem β€” It's taken a long time to get to this point - longer than I would have guessed if you'd asked me back when we first started talking about it - but I'm pretty damn proud of where it's at now.Kent Overstreet's Patreon Unplugged Core Membership Jupiter Signal PROMO 2024 β€” $3 off a month forever.
