NFS (Networkfilesystem), a network file system, is one of the file systems supported by FreeBSD that allows computers in the network to share resources across TCP/IP networks. In an NFS application, a local NFS client application can transparently read and write to files located on the remote NFS server, just as you would access a local file.

Recently in the open source hyper-fusion test, has achieved the very ideal effect: to be centralized, high availability, open source and low cost, can realize any one physical mac

Questions about installing RAC using Openfiler as a shared storageFirst: Be sure to use Openfiler-2.3-x86-disc1.iso This version of the Openfiler, do not use other versions of the Openfiler software, because the use of other versions of the Openfiler software will encounter a RAC node restart and so on.The uname output of the Openfiler virtual machine (Openfiler-2.3-x86-disc1.iso) is: [[email protected] ~]# uname-alinux share 2.6.26.8-1.0.11. smp.pae.
