FreeNAS InstallationFreeNAS will be used to provide virtual NFS storage for ESXi hosts so that ESXi hosts can implement advanced features such as Vmotion, Ha, and more. I allocated 1GB memory, 4 Vcpus, 2GB system disk to FreeNAS, virtual machine DNS name:FreeNAS.contoso.com. Create the FreeNAS virtual Host in VMware Workstation. In the Create Wizard, rem

.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

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

It is not freebsd, It is freenas7.2. Due to a problem with freenas installed for a friend, I studied how to operate raid1 in freebsd command mode yesterday and the night before. I should say how to configure freenas. In fact, freebsd manual says: Http://www.freebsd.org/doc/zh_CN.GB2312/books/handbook/geom-mirror.html The operation is as follows:Gmirror label-vb round-robin raidone/dev/ad8/dev/ad10 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

OpenSolaris 2008.11 was officially released, quickly installed in his own notebook, and would like to experience how ZFS's time Slider feature is powerful. DELL Inspiron 1420 Half a year ago in 1420 has been installed in the version of 2008.05, Live CD boot up, the results of disappointment found on board 100M network card is not supported, so did not continue to install. This is probably the benefit of live CDs, so don't waste your time. But do not give up, or to check a bit, found that someone

Linux2.6.19 kernel released in 2008. When the 2.6.28 kernel was released, EXT4 ended the development and began accepting users ' use. It seems that ext will become synonymous with Linux file systems. However, when you read many articles about EXT4, you will find that you have mentioned btrfs in unison, and that EXT4 will be a transitional file system. Ext4 's author Theodore Tso also praised Btrfs and believes Btrfs will become the next generation Linux standard file system. ORACLE,IBM, Intel a

On solaris, the transfer method is to modify/etc/system, but not on linux.

Storage resources can be scaled elastically in the virtual storage pool as needed, such as expansion or
