Arch bcache. # Bcache is a superb tool which allows users to leverage the incredible read and write speeds of SSDs while still being able # to access their inexpensive and large HDD storage, quickly, Bcache allows one to use an SSD as a read/write cache (in writeback mode) or read cache (writethrough or writearound) for another blockdevice (generally a rotating HDD or array). I've created the backing device as well as the caching device, however when I go to attach the cache Bcache (block 缓存) 允许使用固态硬盘作为读写缓存（writeback模式）或者读缓存（writethrough 或者 writearound模式）来为另一个 block 设备（通常是机械硬盘或硬盘阵列）加速。这篇文章会展示如 如果要看對於 bcache 本身的介紹，請瀏覽 bcache 首頁。 請一定要閱讀並參考 bcache 手冊。 Bcache 從 Linux 內核 3. 7，Bcachefs在此内核中开箱即用。 本文将介绍在Arch Linux中体验Bcachefs的情况。 安装 Bcachefs已经在Arch Linux官方内核的 linux 与 linux-zen 中直接支持，对 Registering the backing device makes the bcache device show up in /dev; you can now format it and use it as normal. I’ve played around with all distros under the sun in VMs and 目前，Arch Linux已经升级到了Linux 6. 08. This Step 2 is to install bcache-tools from the AUR. It contains a kernel built with bcachefs support linux-bcachefs and the associated command line tools bcache-tools. Any advice or tweaks are welcome. (VERY LARGE) But its 100% I've tried several different approached and following the arch, gentoo and the official guide, but regardless I continually stumble. It is built upon Bcache and is mainly developed by Kent Overstreet. Hi all, This is my first post here, but this seems like the best place to get good direction on building my first hardware backed Linux installation. 1 背景介绍Bcache是Linux内核块设备层的软件驱动，使用高速存储设备为传统机械磁盘 bcache is licensed under the GNU General Public License (GPL), and Kent Overstreet is its primary developer. Bcache (block 缓存) 允许使用固态硬盘作为读写缓存（writeback模式）或者读缓存（writethrough 或者 writearound模式）来为另一个 block 设备（通常是机械硬盘或硬盘阵列）加速。 这篇文章会展示如 Bcache (块缓存) 允许使用 SSD 作为另一个块设备（通常是旋转的 HDD 或阵列）的读/写缓存（在 writeback 模式下）或只读缓存（writethrough 或 writearound）。 本文将介绍如何使用 Bcache 作为 I'm trying to set up a cached block device with bcache. . But the first time using a new bcache device, it’ll be running in passthrough mode I have a 16 GB optane drive that I want to use as a caching device with a 1TB HDD. Following the arch guide: Bcachefs は、 Btrfs と ZFS の機能をよりクリーンなコードベース、より安定性、より高速、GPL 互換のライセンスを提供することを目的とした次世代の CoW ファイルシステムです。 Bcache は、主 如果您的 bcache-tools 没有更新到最新版本并且没有统一的 bcache 实用程序，您可以使用旧的 make-bcache 实用程序来格式化具有相同 -B 和 -C 参数的 bcache 设备。 bcache-tools 现在附带 udev 规 Bcache (block cache) allows one to use an SSD as a read/write cache (in writeback mode) or read cache (writethrough or writearound) for another blockdevice (generally a rotating HDD or array). Warning Bcachefs is an experimental file Does that mean that the current stock kernel for Arch Linux is erroneously compiled without bcache support, or am I doing something wrong? Any help would be greatly appreciated! It is probably for precisely this reason that Arch enables the bcache kernel module in its default kernel compile but provides no supported means of making use of it. 01 版本開 关注公众号 singless ，后台回复bcache，获取bcache相关资料 1 介绍1. I first was using the information in the Arch Wiki. Patrick's Blog - Patrick Lauer (Patrick) , a Gentoo developer, wrote a few short entries on his blog concerning the use of bcache and a multi . Question: how can I install packages from the AUR if I don't have the base-devel group installed on my system yet? 目标： 我要做的事情是：修改文件系统，硬盘分区方案，但是不重装系统，整个操作不被应用层感知。 背景： 我的笔记本 ThinkPad T450。8G内存 + 16GB SSD + 1TB HDD。预装windows7。 在预装系 How to set up bcache? I've started installing arch on a new machine and intend to use bcache, but I've ran into a problem. (It doesn’t even have a notion of a clean shutdown; bcache simply doesn’t return writes as completed until It allows one or more fast storage devices, such as flash-based solid-state drives (SSDs), to act as a cache for one or more slower storage devices, such as hard disk drives (HDDs); this effectively Bcache allows one to use an SSD as a read/write cache (in writeback mode) or read cache (writethrough or writearound) for another blockdevice (generally a rotating HDD or array). and if needed i can put mine whole install wikipage here. According to the Arch DESCRIPTION The bcachefs utility supports the following subcommands, which are documented in detail below: Superblock commands format Format one or a list of devices with bcachefs data bcache has been in mainline kernel for years and should be perfectly stable. I used it on my system around the time it got merged without any issues 在Linux下，使用SSD为HDD加速，目前较为成熟的方案有：flashcache，enhanceIO，dm-cache，bcache等，多方面比较以后最终选择了bcache。 bcache 是一个 Linux 内核块层超速缓存。 Bcache (block 缓存) 允许使用固态硬盘作为读写缓存（writeback模式）或者读缓存（writethrough 或者 writearound模式）来为另一个 block 设备（通常是机械硬盘或硬盘阵列）加速。这篇文章会展示如 For all discussion about bcachefs: a new copy on write filesystem with checksumming, compression, caching, replication, and more Bcachefs 是一種寫時複製（CoW）文件系統，支持多設備、RAID、壓縮、校驗和加密。 它旨在提供類似於 Btrfs 和 ZFS 的現代功能。 Bcachefs 基於 Bcache，兩者都主要由 Kent Overstreet 開發。 警 Mounted the bcache partition to a loop device with sudo losetup -f /dev/[DEVICE] -o 8192 The bcache data is probably only 1KiB or less, but the offset needs to align with the sector size of the disk, in this This is an unofficial repository for Arch Linux to ease testing bcachefs. 10 版本開始就已經併入 mainline，而 Arch Linux 的安裝盤自從 2013. It aims to provide modern features similar to those of Btrfs and ZFS. I don't want to remove anything from my PC. /sys/fs/bcache does not exist on the installation medium. Bcache (block cache) allows one to use an SSD as a read/write cache (in writeback mode) or read cache (writethrough or writearound) for another blockdevice (generally a rotating HDD or array). Overstreet considers bcache as a "prototype" for the development of bcachefs, a Bcache (block 緩存) 允許使用固態硬盤作為讀寫緩存（writeback模式）或者讀緩存（writethrough 或者 writearound模式）來為另一個 block 設備（通常是機械硬盤或硬盤陣列）加速。這篇文章會展示如 And use the rest of the SSD with Bcache to speedup files from the HDD. How do I enable bcache? Arch wiki - The Bcache article on found on the Arch wiki. Bcache goes to great lengths to protect your data - it reliably handles unclean shutdown.
