You no longer need to remember the usage of various professional concepts, various commands, newfs, metinit and various volume managers. As long as various storage devices are added to the same ZFS pool, you can easily manage and configure the file system in this ZFS pool. All storage devices are managed through ZFS pool. Therefore, there will be no such concept of inconsistent, and naturally there is no need for this tool.Īs a new file system, ZFS completely abandons the traditional file system + volume manager + storage architecture. Cow will not rewrite the existing files on the hard disk to ensure that all files on the hard disk are valid. What’s worse, if a server needs to do fsck, it can only be offline, and the existing applications are often large hard disks, and the corresponding fsck repair time is also very long, which is almost unbearable for many users using the server.Īfter using ZFS, you can completely abandon fsck, because ZFS is a file system based on cow (copy on write) mechanism. This period of time is very time-consuming and may not be able to repair successfully in the end. Whether you are using Linux, UNIX or windows, I believe we all have a similar experience: when the system is accidentally powered off or illegally shut down, and the file system is found to have an inconsistent problem after the system is restarted, it needs fsck or ScanDisk to repair. Ten reasons and characteristics of using ZFSġ. Not only that, you can also increase the storage capacity of the pool by adding hard disks. #Zfs raid level openzfs series#This means that unlike other file systems, ZFS can create file systems that span a series of hard disks or pools. Unlike most file systems, ZFS combines the characteristics of file systems and volume managers. If you are interested in trying ZFS on Linux, there are a lot of tutorials on ZFS on Linux to guide you. #Zfs raid level openzfs install#As far as I know, no Linux distribution can install ZFS on the root directory for out of the box use. If you want to try ZFS on Linux, you can only use it on the storage file system. In fact, ZFS support is the main reason why some experienced Linux users choose BSD. Illumos is a clone of the OpenSolaris kernel. If you want to use ZFS (out of the box) immediately, you need to install FreeBSD or an operating system using illumos kernel. Let’s take a closer look at some of these features.
