How to install ZFS on Ubuntu Linux 16.04 LTS

ZFS (Zettabyte File System) is a popular open-source filesystem that provides advanced features such as data integrity checks, snapshotting, and replication. It is widely used on servers and workstations running Linux and other operating systems.

To install ZFS on Ubuntu Linux 16.04 LTS, follow these steps:

1. Update the package manager's package list by running the following command:

sudo apt-get update

2. Install the ZFS kernel modules and userspace utilities by running the following command:

sudo apt-get install zfsutils-linux

This will install the ZFS kernel modules and userspace utilities and any dependencies required.

3. To create a ZFS pool, you will need at least one block device, such as a disk or partition. Identify the device name of the block device using the lsblk command. For example, if the device you want to use is /dev/sdb, the device name is sdb.

4. Run the following command to create a ZFS pool using the block device:

sudo zpool create <pool name> <device>

Replace <pool name> with the name you want to give to the pool, and <device> with the device name of the block device. For example:

sudo zpool create mypool sdb

This will create a ZFS pool called mypool using the sdb block device.

5. To verify that the pool was created successfully, run the following command:

sudo zpool list

This will display a list of ZFS pools on the system, including the one you just created.

6. To create a ZFS filesystem on the pool, run the following command:

sudo zfs create <pool name>/<filesystem name>

Replace <pool name> with the name of the pool you want to create the filesystem on, and <filesystem name> with the name you want to give to the filesystem. For example:

sudo zfs create mypool/myfilesystem

This will create a ZFS filesystem called myfilesystem on the mypool pool.

7. To verify that the filesystem was created successfully, run the following command:

sudo zfs list

This will display a list of ZFS filesystems on the system, including the one you just created.

That's it! ZFS is now installed and configured on your Ubuntu Linux 16.04 LTS system. You can use it to store and manage your data using advanced features such as snapshotting and replication.
