As a new feature of Solaris 10 and OpenSolaris, ZFS attracts the attention of many in the open source community, and Linux's father, Linus Torvalds, openly represents a particular interest in the Solaris Software's ZFS (zettabyte file system), It is considered that the system manages files in hard disk storage mode, has built-in function spanning multiple hard di

The ZFS file system under the Linux platform is categorized in two, one is ZFS implemented in user space, and one is ZFS implemented through kernel modules.User-space-enabled ZFS has not been maintained for several years, and without stability, performance alone cannot be us

Solaris zfs Replace the Root Pool Disk (Replace a Disk in the ZFS Root Pool) in some cases, due to insufficient space or hardware faults, we need to Replace the boot Disk. The redundancy pool (mirrored pool) is relatively simpler than the hard disk in an image pool. You only need to use the replace command to directly replace the hard disk. # Zpool offline rpool upgrade # export ADM-c unconfigure c1: dsk/c1

Overview I have always strongly recommended ZFS because it is so easy to use. However, it can only run on Oracle's Solaris and FreeBSD systems until now. To share it with other systems, you can only use NAS or SAN. The NAS method is very simple. I have been using Samba for implementation. Of course NFS is also acceptable. I haven't tried SAN before. Of course SAN is better to use, and the network speed is fast enough now. Although NAS and SAN are both

or laptop is broken, I don't have to worry about rescuing data stored on my computer. Because nothing is ever saved in my home such a device.But it's not a good idea to put all the eggs in one basket. So, you have to add redundancy to it to ensure that there are multiple physical backups.ZFS is the answer.Here are two excellent file systems to do this work: ZFS and Btrfs.Btrfs is very new and still in deve

DustinKirkland from Canonical's product and policy team confirms that Ubuntu plans to bind core modules of ZFS file systems. He wrote: zfs. ko is a file system module of a self-container. This module is not from the Linux kernel, but from OpenZFS and OpenSolaris. This independent situation has existed for many years, e

in NVRAM when the disk read operation is complete, in this way, read latency can be hidden from users. Of course, this method is only effective before the NVRAM buffer is used up. No problem! Your storage vendor will say. Just pay more in cash and buy more NVRAMThat's all. The problem cannot be solved without your wallet. Some storage write operations have raised another issue in the transaction file system (such as
