1. Introduction:It is said that XFS has the ability to de-duplicate data, and unscrupulous people continue to ask for the Samba shared disk using the CENTOS7 on the use of XFS to ZFS, and turn on the deduplication function. Samba configuration SeeHttp://www.cnblogs.com/demonzk/p/6518675.html2. Environment:Os:rhel 7.2KernelZfs:3. Download and install:Since ZFS is not carried in the installation disk or Epel,

access both the directories and files under SYS1 and the files in the SYS2. 3. File System Owner: It is still assumed that there are two systems in the Sysplex environment, SYS1 and SYS2. How can users who log on to SYS1 access the file system in SYS2? This needs to send a request from SYS1 to SYS2, request SYS2 to complete the corresponding operation for SYS1, this process is called function-shipping. Here, SYS2 acts as the actual operating file system, so SYS2 is called owner of the filesys

.x or Ubuntu 15.10, perform some operations according to the LXD 2.0 series (II): installation and configuration, and then return. Make sure that the package list has been updated: sudo apt update sudo apt upgrade InstalllxdPackage: sudo apt install lxd If you have installed Ubuntu 16.04, you can store your container files in the format of ZFS file system. Linux kernel in Ubuntu 16.04 contains the necessary kernel modules that support

on each piece of hard disk, found that a hard disk on the same strip of data and other hard disk obviously different, so initially determine that the hard disk may be the first to drop the line, through the North Asia self-developed RAID verification program to check this strip, found that the hard disk analysis just analyzed the data is the best, So you can identify the hard drive that was first dropped.5. Analyzing LUN information in a RAID groupBecause the LUNs are based on RAID groups, the

two pieces of disk damage is not related to the cause of MTBF basically. Today, I was just testing a ZFS array to clearly check the data and see the results, so I just analyzed the reason.In this case, the first thing to do here is to introduce a concept that is not often accessible to ordinary people:ber hard drive Ber, English is ber (Bit Error rate), is a very important parameter to describe the performance of hard disk, is a parameter to mea

Test data of PostgreSQL running on FreeBSD and Linux This afternoon I wanted to test DragonFly dports. I suddenly wondered why I didn't compare the performance difference between PostgreSQL in BSD and Linux. For this reason, I set some standards to compare the performance differences on different operating systems. I use the same hardware and software to obtain data more accurately. These tests are based on PGSQL9.1. After I tested it In Debian Linux, I was surprised by the results. So I did a
