An old hard disk is attached to the server. if you want to format the historical data and save it, use fdisk to report the following error: An old hard disk is attached to the server. if you want to format the historical data and save it, use fdisk to report the following error: /Dev/sda1 isapparently in use by the system; will not make a filesystem here! In general, this is because the disk has been used by the system or mounted to another place. use mount and df-lh to confirm that the disk is

Server RAID disk array information loss is a nightmare for many webmasters or server administrators, if you have ever experienced a similar RAID disk data loss and then look around for data recovery company things, then you must be fresh in memory of RAID disk data recovery, if you've never experienced it, just heard about it, Then you must look down, the reasons

Hard disk partition, there are three kinds, primary partition, extended partition, logical partitionA hard disk primary partition has at least 1, a maximum of 4, and an extended partition can be no more than 1. and the primary partition + extended partition must not exceed 4 total. A logical partition can have several.The extended partition cannot be used directly, it must be used to separate the logical partition, and the logical partition exists in the extended partition. Logical partitions ar

In linux, you can view the raid information of a server. 1. for software raid, you can use cat/proc/mdstat md1: active raid1 sdb3 [1] sda3 [0] 480572352 blocks [2/2] [UU] md3: active raid1 sdb2 [1] sda2 [0] 1952704 blocks [2/2] [UU] md2: active raid1 sda1 [0] sdb1 [1] 194496 blocks [2/2] [UU] I made a soft RAID 1 (sda, sdb two hard disks ). soft

Software RAID: can only be viewed by the Linux system itselfCat/proc/mdstatYou can see information such as RAID level, status, and so on.Hardware RAID: The best way to do this is through the management tools of the installed RAID vendors, with CmdLine and graphical interfaces. such as the Adaptec company's hardware car

With a new computer, ready to install a dual system, Windows used to play games, Linux to write code. Dedicated to buy two 1T hard drives, want to use to build RAID0, using parallel I/O to improve the performance of the computer. Select the motherboard when selected to support the raid of the motherboard, MSI B85-g43 Gaming, can use MSI super RAID technology, but bought after found that the driver of this

The Linux system does its own raid, regardless of the underlying disk.The Raid,mdadm tool, which incorporates the MD module (Multi disks) in the kernel, can invoke the MD module in the kernel.Mdadm is a command to create a raidfunction mode:-C Create raid-A re-assemble the raid by scanning the

1. What is RAID5? Raid Level 5 is a storage solution that combines storage performance, data security, and storage costs. It uses the Disk Striping technology. RAID 5 requires at least three hard disks. Instead of backing up the stored data, RAID 5 stores the data and the corresponding parity information on each disk that makes up

1: Raid DefinitionRaid, full name: Redundant Array of Inexpensive Disks. The Chinese name is a Redundant Array of cheap disks. raid can be divided into soft RAID and hard raid. Soft Raid achieves redundancy of multiple hard disks through software. however, hard

We know that there are several common types of RAID technologies, altogether there are 7 0~6, of which raid 0, RAID1, RAID 5 and RAID6 are more commonly used. In peacetime work, we should choose which RAID technology type is very important, the following days Shield data Recovery Center Experts even tell you how to cho

RAID is an abbreviation for the English Redundant array of independent disks, which is known as a standalone redundant disk array. Simply put, RAID is a combination of multiple separate hard disks (physical hard disks) in different ways to form a hard disk group (logical hard disk), providing higher storage performance than a single hard drive and providing data backup technology.

As you know, hardware RAID solutions are fast, stable, and can effectively deliver high levels of hard disk availability and redundancy, but high prices are daunting. Fortunately, Windows 2003 provides built-in software RAID capabilities, and soft RAID enables RAID-0, RAID-1

I recently learned how to configure raid in linux as follows:1. Preliminary workChange the system id of the partition to fd.2. raidMdadm-C/dev/md2-l 5-n 3/dev/sdb8/dev/sdb9/dev/sdb10-C is the name specified for creating a raid volume/dev/md2-L the specified raid level is also a raid type.-N: specify several devices (pa

The latest HP X86 server is the GEN8 series, which uses the ACU tool to create RAID, which is a graphical interface that can be said to be friendlier.Originally usually if is to buy a new server, standard two hard disk, then the default is done Raid1, but there are accidents, due to the large amount of PC server, a lot of this situation, you need to manually configure the raid, here use my photo to explain.

I. LVM logical volume Management 1. Definition Logically combine multiple physical partitions/disks into a larger whole, and divide different logical partitions. The size of logical partitions can be expanded and reduced as needed. 2. LVM Concept PV: physical volume VG: volume group (which can contain 65534 PES) LV: logical volume that truly stores data PV physical volume ---> VG volume group ---> LV logical volume ---> Format ---> mount the File System 3.

The same thing that I see is the case of the RAID card LSPCI stands for list PCI. Think of this command as "LS" + "PCI". This would display information about all the PCI bus in your server. Apart from displaying information about the bus, it'll also display information about all the hardware devices Connected to your PCI and PCIe bus. For example, it would display information about Ethernet cards, RAID co

Recently, my instructor asked me to configure a Samba server for the new Dell r900 server in the lab, sharing Linux and Linux Files on two PCs in the lab, and sharing Windows and Linux Files. However, when installing the server system, I am a newbie and have not installed any servers. Follow the instructions in the instruction manual to install the boot disk. The first step is to click "Server Settings" on the main interface, why is an error prompted? You can click "re-boot", but the problem s
