This is a tuning option that will increase the value of writeback_rate_fp_term_ {low|mid|high} by this factor . This is useful to optimize the rate when one cache device is shared by multiple backing devices, especially useful when those backing devices have the same size and similar workloads, e ... If you want to permanently destroy the bcache volume, you need to wipe the bcache superblock from the underlying device. This operation is not exposed through the sysfs interface. So: Stop the bcache device as usual with echo 1 > /sys/block/<device>/bcache/stop. On newer kernels this may fail with "Permission denied".Provided by: bcache-tools_1.0.8-2build1_amd64 NAME make-bcache - create a cache device SYNOPSIS make-bcache [ -U UUID] [ -b bucket-size] device OPTIONS-C Create a cache -B Create a backing device (kernel functionality not yet implemented) -U UUID Create a cache device with the specified UUID -b bucket-size Specifies the bucket size. For Ubuntu package caching, no further configuration of Apt-Cacher-Ng is required. You can now configure the other Ubuntu machines on the network to use the Apt-Cacher-Ng package cache server. Configuring Ubuntu Package Manager with Proxy: Now, on another Ubuntu machine on the network, create a new file /etc/apt/apt.conf.d/02proxy as follows: bcache-tools now ships udev rules, and bcache devices are known to the kernel immediately. Without udev, you can manually register devices like this: echo /dev/sdb > /sys/fs/bcache/register echo /dev/sdc > /sys/fs/bcache/register. Registering the backing device makes the bcache device show up in /dev; you can now format it and use it as normal.Dec 29, 2021 · Ask Ubuntu: I made a fresh install of ubuntu 20.04 on my desktop, and then, from within the installation, created a bcache device to put my /home sudo make-bcache -C /dev/sdb4 -B /dev/sda1 Where /dev/sdb is the ssd and /dev/sda is the hdd.

With the help of bcache, you can use a smaller SSD as a caching drive for the larger, slower HDD. With this set up, you have the best of both worlds. A lightning fast SSD housing your operating system. A bcache-enabled SSD that caches for your large HDD data drive.

I'd think the sane approach is to cache the resulting MD device. bcache is designed to pass-trough sequential reads and writes. If you bcache each device separately, logically, several devices striping into a raided or stripped MD, will, from the bcache perspective, constantly be writing random blocks. While a bcached MD volume will look as ... Here are the major steps: Boot the Ubuntu installer. Create a partitions for /boot, the backing, and cache devices. Create the bcache device.
