In the case of KVM or Xen virtualization, it is often necessary to use the mirror files (image file), we can start the guest system, and then modify the mirrored file, but this is sometimes more cumbersome, in fact, can be the image file directly mount, There are two ways to do this.method One: Find the starting position of the partition, and use the offset parameter of the Mount command to offset the unwanted before you can get the real partition. the specific steps are as follows:1. Use "Fdisk

recovery. Disadvantage: write performance is slightly worse than RAID 0 + 1 (same read performance) My ideas The newly added hard disks are divided into four 1G areas, namely 1, 2, 3, and 5. Convert each two to a RAID 1 volume/dev/md {1, 2} Convert the two RAID 1 volumes into a RAID 0 volume/dev/md0 Convert RAID 0 to pv and vg Then create your own space through lv This space is RAID 1 + 0. Detailed implementation process Here we add a hard disk 2 for the experiment. We do not want to resta

integrated with the motherboard, it has become a choice for players, especially those who need large storage space, such as video and audio production. The initial RAID is divided into different levels, each of which has its own theoretical advantages and disadvantages. Different Levels strike a balance between the two targets, increasing data reliability and increasing storage (group) read/write performance. Over the years, applications with different RAID concepts have emerged.How to Create a

Linux tips 5-format a USB flash drive and linux tips 5 -- Generally, it is very easy to format a partitioned USB flash disk. You only need to use The mkfs command to specify the target file system. The example is as follows: $ sudo fdisk -l$ sudo mkfs -t vfat /dev/sdb1 The-t parameter is the target file format. Other parameters include ext3 and msdos. The default value is ext2.We can also use the following simple command to do this: mkdosfs(8), mke2fs(8), mkfs.bfs(8), mkfs.ext2(8), mkfs.ext

the terminal and run sudo gparted The gparted tool will be opened, right-click the gray unallocated area, create and format a file system in ntfs format (after the operation is complete, remember to click the application above the interface), and shut down.Install win7 Plug in the boot disk of Windows 7 after shutdown. Similar to opening the boot disk of ubuntu, install Windows 7 in the new partition. After the installation is complete, the system will automatically enter the windows system. If
