On the afternoon of June 9, Apple introduced the next generation Mac OS X operating system to various developers at the annual WWDC 08 Convention (the Apple Worldwide Developers Conference 2008). Code-named Snow Leopard Snow Leopard, is expected to be officially released within a year. It is reported that Snow Leopard will focus on improving performance and stability, which will optimize the core processor and introduce a new technology called "Grand Central" to simplify the process of programm

ability is poor.LVM is almost a hot backup, supporting all engines, snapshot-based (LVM,ZFS) physical backups, very fast, almost hot standby. Only affects data for a few seconds. However, the process of creating the snapshot itself affects the use of the database online, so the backup speed is faster, the recovery speed is relatively fast, there is no elastic space, and the limitations of LVM: The multiple logical volumes can not be backed up at the

(Request ("CXNR"))Set ox=nothing%> This is written in VB script ASP scripting, very simple. First you create a COM object instance, which is similar to the CreateObject () in Visual FoxPro: Set Ox=server.createobject ("Vfpweb.computertest") Once you have created a COM object instance, you will call it. At this time through the ASP request object to get query parameters cxxx and CXNR, because VB Script only one type of data is Variant, in order to ensure that COM communication, parameter data

Distributed File Systems, cluster file systems, and parallel file systems are easy to confuse. In fact, they are often used in different regions. Some people always ask about the differences and connections between the three. In fact, there are indeed overlapping concepts between them, but there are also significant differences. Distributed File System Naturally, "distributed" is the focus, which is relative to the local file system. A Distributed File System is usually a C/S architecture or Ne

When copying a large number of files, it is inconvenient to use CP (for example, after the command is accidentally interrupted, it cannot be resumed; if it is forcibly overwritten, it will waste time; if it is not overwritten, echo "N" | CP-r/source/destination can be used to complete the task. However, after my experiment, the overwriting prompt passed to the CP will also delay time, so there is also a waste of time for existing files) Rsync has many features to avoid the inconvenience of CP me

release of the enclosure, although it is now alpha, even pre-alpha. Because the file system expansion program is not unified, the expansion in this release only support GlusterFS, but cloud technology has been on the ceph, cinder on the prototype, I believe in 1.9 can be launched in the community. Local temporary storage has been in a stable alpha version after 1.7 and 1.8 two iterations, and subsequent scenarios will no longer change and we will con

distributed file systems, as well as storage support provided on the IaaS platform, which are distributed across the network and share file systems, so we call this type of data volume a network data volume.Network data volumes can meet the persistent demand of data, pod is configured to use network data volumes, each time the pod is created, the remote file directory of the storage system is attached to the container, the data in the data volume will be saved for a long time, even if the pod i

Kubernetes using NFS as a shared storageKubernetes managed containers are encapsulated, and sometimes we need to put logs from the container running locally or shared storage to prevent the container from going down, and the logs can also analyze the problem. Kubernetes's shared storage scheme is currently more prevalent in three, namely: Nfs,glusterfs and Ceph.Previously wrote an article kubernetes use Glusterfs
