To mount the encrypted Btrfs filesystem at boot time, you need to:
- decrypt the storage device /dev/sdb at boot time using the /etc/cryptkey encryption key file.
- mount the decrypted storage device /dev/mapper/data to the /data directory.

Why is btrfs so slow?
btrfs is always going to be slow in write heavy workloads due to being a COW filesystem. If you need the extra speed in that specific workload why not just disable the COW features using chattrib.
Can Btrfs be encrypted?
Btrfs does not support native file encryption (yet), and there's nobody actively working on it. It could conceivably be added in the future. As an alternative, it is possible to use a stacked filesystem (eg. ecryptfs) with btrfs.
Is Btrfs dead?
In terms of developer involvement Btrfs is not dead, far from it. It gets new patches, which are not maintenance only, in every new kernel release.
Is Btrfs cluster aware?
BTRFS is also flash drive aware with direct support for the TRIM/discard operations. ... In addition, BTRFS is the underlying storage system for Ceph, an open-source cluster file system.
Is Btrfs slower than ext4?
Some performance observations on Btrfs vs Ext4 random-read/write I/O. I mean it's not really surprising that BTRFS is slower than EXT since it checks the checksums of blocks it reads to validate that the data isn't corrupted. ... It's not just slow because of the checksums, it's also because of CoW.
Is ext4 faster than Btrfs?
For pure data storage, however, the btrfs is the winner over the ext4, but time still will tell. Till the moment, the ext4 seems to be a better choice on the desktop system since it is presented as a default file system, as well as it is faster than the btrfs when transferring files.
Why should I use Btrfs?
Advantages of Btrfs over Ext4:
The main features of the Btrfs filesystem that are useful to everyday Linux users are: Built-in Filesystem-level snapshots. Multiple device support. Built-in RAID support.
Why do I like Btrfs?
btrfs commands are very easy, snapshots look like directories, I can create them, delete them, move them around, boot into, replace stuff just like with normal files and folders. ... Also there is a greater availability of open-source CLI and GUI programs for btrfs than for ZFS (on desktop (!)
How do I turn off Btrfs?
how to disable 'scanning btrfs filesystem' at system startup
- blacklist the brtfs module in /etc/modprobe. d.
- remove btrfs-tools.
- renamed the executable /sbin/btrfs to p.e /sbin/btrfs. save.
Is Btrfs good yet?
in my opinion BTRFS has been ready since kernel 4.14, but lots of people have been using it without problems since well before that. it's well and truly good now, and improving with every new kernel version.
Why did Red Hat drop Btrfs?
However, despite being under development for more than 10 years, Red Hat discovered through feedback that Btrfs was not considered stable enough by its customers. As a result, Red Hat is focusing on offering the features that its customers need without relying on Btrfs.
Can Windows read Btrfs?
Btrfs for Windows by Paragon Software is a driver that allows you to read Btrfs-formatted files on a Windows computer. Btrfs is a copy-on-write file system designed at Oracle for use in a Linux environment. Just plug in Btrfs storage to your PC and get a read access to the content with Btrfs for Windows driver.
