Is ZFS better than LVM?

You can use RAID over LVM or ZFS (ZFS is can work both RAID and LVM). In my opinion, ZFS works better than LVM, but: on Solaris 10/11/OpenSOlaris only, you can't use it from linux. ZFS is disk management and filesystem, LVM allow to use any filesystem you need.

What is the difference between LVM and RAID?

RAID aims to improve redundancy whereas LVM aims to improve DATA management and handling. ... LVM is a method of logically partitioning your memory device over multiple disks in order to have a single or multiple partition over multiple disks. LVM is purely a software which manages multiple disks.

Why is ZFS better than hardware RAID?

For example, instead of a hardware RAID card getting the first crack at your drives, ZFS uses a JBOD card that takes the drives and processes them with its built-in volume manager and file system. This gives ZFS a greater control to bypass some of the challenges hardware RAID cards usually have.

Does LVM use RAID?

This article will provide an example of how to install and configure Arch Linux with Logical Volume Manager (LVM) on top of a software RAID. Tip: LVM itself supports logical volumes in RAID configurations. See LVM#RAID for an alternative to this article.

Is ZFS faster than ext4?

That said, ZFS is doing more, so depending on the workload ext4 will be faster, especially if you have not tuned ZFS. These differences on a desktop will probably not be visible to you, especially if you already have a fast disk.

Should I enable LVM?

The answer depends on the actual use case. LVM can be extremely helpful in dynamic environments, when disks and partitions are often moved or resized. ... However, in a static environment where partitions and disks are never changed, there is no reason to configure LVM unless you need to create snapshots.

What is difference between LVM and standard partition?

In my opinion the LVM partition is more usefull cause then after installation you can later change partition sizes and number of partitions easily. In standard partition also you can do resizing, but total number of physical partitions are limited to 4. With LVM you have much greater flexibility.

What are the advantage of LVM and RAID compared to standard partition?

Using logical volumes, you can take device snapshots for consistent backups or test the effect of changes without affecting the real data. The only difference between RAID and LVM is that LVM does not provide any options for redundancy or parity that RAID provides.

What is RAID LVM?

It's a much simpler setup with more flexibility. You can use all of the disks in the RAID volume and slice and dice them whatever way you like with LVM. ... If you tried to RAID LVM volumes, you would be left with a normal device without any of the LVM volume benefits (e.g. growing filesystems etc.)

Is ZFS better than RAID?

ZFS is an awesome file system that offers you way better data integrity protection than other file system + RAID solution combination.

What is so good about ZFS?

Pooled Storage

Unlike most files systems, ZFS combines the features of a file system and a volume manager. This means that unlike other file systems, ZFS can create a file system that spans across a series of drives or a pool. Not only that but you can add storage to a pool by adding another drive.

Do I need raid with ZFS?

With ZFS you only need HBAs, not RAID controllers, which cost a lot less. You will want to at most use Z2, Z3 will run like crap and it is rarely used. There are other ways to mitigate your failure scenarios.
