Encrypting ZFS on Ubuntu 20

With either option, all ZFS features are fully available. ZFS native encryption is not available in Ubuntu 18.04. Unencrypted does not encrypt anything, of course. With no encryption happening, this option naturally has the best performance. LUKS encrypts almost everything. The only unencrypted data is the bootloader, kernel, and initrd. The system cannot boot without the passphrase being. An upcoming feature of OpenZFS (and ZFS on Linux, ZFS on FreeBSD, ) is At-Rest Encryption, a feature that allows you to securely encrypt your ZFS file systems and volumes without having to provide an extra layer of devmappers and such. To give you a brief overview of what the feature can do, I thought I'd write a short post about it

K3s on Ubuntu 20.04 with root on encrypted ZFS · GitHu

  1. Ubuntu 18.04 LTS and newer Ubuntu versions no longer include an option in the installer to encrypt the home directory.This option was removed from the Ubuntu installer because it uses eCryptfs, which is considered buggy, under-maintained, and the recommended alternative is a full disk encryption using LUKS. For per-directory encryption, like the home folder, it's recommended to use fscrypt.
  2. Doing some more extended research I have found many tutorials on installing FreeBSD naively to a ZFS volume and mounting it as / It wasn't till I did more research and found an article on mounting a zfs encrypted volume as root. Later I found that FreeBSD 10 does this during installation, which is awesome to say the least
  3. We will use per dataset encryption (with ZFS inheritance property) and per-user encryption. So, for your system, the request will be in the initramfs, before calling pivot_root, which is early in the boot process (just after importing the pool). Would that cover your use case ? 1 Like. mcamou July 17, 2020, 8:06am #61. We are going to add encryption support for new installs in a future 20.04.X.
  4. Encryption root inheritance can be tracked via the read-only encryptionroot property. Encryption changes the behavior of a few ZFS operations. Encryption is applied after compression so compression ratios are preserved. Normally checksums in ZFS are 256 bits long, but for encrypted data the checksum is 128 bits of the user-chosen checksum and 128 bits of MAC from the encryption suite, which.

Hey everyone! Here is the place to discuss about my new blog post series on the work we have done in Ubuntu 20.04 LTS on ZFS experimental support and ZSys.

abstract: Bleeding edge Linux releases (Ubuntu 19, for example) now provide a mechanism to install the operating system on a ZFS root filesystem. This is quite useful for installing the OS on a laptop with a single drive and still be able to take advantage of many ZFS benefits, like compression and encryption, but many prefer the comfort of long term support (LTS) versions zsys. zfs. didrocks June 19, 2020, 10:26am #1. Hey everyone! Here is the place to discuss about my new blog post series on the work we have done in Ubuntu 20.04 LTS on ZFS experimental support and ZSys. This is the place to discuss about the content and I'll update this first post to reference any new episods Many block-level disk encryption solutions are available, and they are all compatible with ZFS. PC BSD (a FreeBSD derivative) even offers support for an encrypted ZFS root filesystem in the installer; a simple click is enough to set it up. On Linux, this procedure is not as simple. No installer offers the option to use ZFS at all at the moment. With some additional effort, however, this is not too difficult to achieve

Before using zfs encryption we should note that there also some requirements: zpool version: the zpool version should be 30 or higher. Root file system: the as of this writing, root file system cannot be encrypted. The zfs encryption property is read-only, you can not set it after the file system was created ZFS on root This is part 2 of our blog post series on our current and future work around ZFS on root support in ubuntu.

  1. Experimenting with Ubuntu's new (relatively so) ZFS installation option is all very well, but encryption is not optional for a laptop that is taken around the place. Whether I should have spent more time poking around the installer to find the option is a possibility, but post-install enabling encryption isn't so difficult. The first step is to create an encrypted filesystem - encryption.
  2. This guide supports the three different Ubuntu encryption options: unencrypted, LUKS (full-disk encryption), and eCryptfs (home directory encryption). Unencrypted does not encrypt anything, of course. All ZFS features are fully available. With no encryption happening, this option naturally has the best performance. LUKS encrypts almost everything: the OS, swap, home directories, and anything.

ZFS is both filesystem and logical volume abstraction, so to implement different keys on different filesystems on ZFS, you'd need to expose them as block devices, not filesystems, and then use your encryption du jour on them, then your filesystem atop that - which also kills most of your compression or encryption properties, since you're doing it before ZFS sees the data, so to speak So, in this guide I will show how to install Ubuntu 20.04 with the following structure: a btrfs-inside-luks partition for the root filesystem (including /boot) containing a subvolume @ for / and a subvolume @home for /home with only one passphrase prompt from GRUB; either an encrypted swap partition or a swapfile (I will show both Encrypting and auto-boot-decryption of an LXC zpool on Ubuntu with LUKS. So we have seen some postings online that suggested you can't encrypt an lxd zpool, such as this GitHub posting here, which correctly explains that an encrypted zpool that doesn't mount at startup disappears WITHOUT WARNING from your lxd configuration A key file could be for example put on a root filesystem if it is encrypted. If the key is not on the root filesystem, you will also need to set zfs-import-poolname.serviceConfig.RequiresMountsFor=/path/to/key, where poolname is the name of the data pool. This makes sure that systemd will mount the filesystem for /path/to/key first before importing the zfs pool. Unlock encrypted zfs via ssh on boo

[1] is a nice explanation of getting set up with ZFS root on Ubuntu 16.04 with explanations for what each of the commands are doing.

Ubuntu 19.10 is a first round towards that goal. We want to support ZFS on root as an experimental installer option, initially for desktop, but keeping the layout extensible for server later on. The desktop will be the first beneficiary in Ubuntu 19.10. Note the use of the term 'experimental' though Ubuntu 20.04 did not provide an option to encrypt your home directory when using ZFS. Ubuntu did previously provide this option, but it used eCryptfs which was considered buggy, under-maintained, [and] not fit for main anymore and has thus been removed

Resolving a Missing or Removed Device. If a device cannot be opened, it displays the UNAVAIL state in the zpool status output. This state means that ZFS was unable to open the device when the pool was first accessed, or the device has since become unavailable. If the device causes a top-level virtual device to be unavailable, then nothing in. ZFS ist ein von Sun Microsystems entwickeltes transaktionales Dateisystem, das zahlreiche Erweiterungen für die Verwendung im Server- und Rechenzentrumsbereich enthält. Hierzu zählen die vergleichsweise große maximale Dateisystemgröße, eine einfache Verwaltung selbst komplexer Konfigurationen, die integrierten RAID-Funktionalitäten, das Volume-Management sowie der prüfsummenbasierte. Summary. Within ZFS, file system creation and manipulation within zpool storage is closer to that of making a new directory than it is to volume manipulation in a traditional file system sense.
