 1. QuestionsWhat is the difference between a direct mount drive and a mount partition in Linux?such as/dev/sdb's hard drive, directly mkfs.ext4/dev/sdb after mount use,and the first Fdisk partition, which is used in the MKFS on Mount,What is the difference between the two?2. Answer 1Are you sure you don't want to partition? Instead of a hard drive just into one area?Direct use of/dev/sdb hard drive, direct MKFS.EXT4Can I use it?3. Answer 2The operation is as follows:[Email protected]_storage

Before also more or less know Linux Disk Management, including hard disk, logic disk, LVM, but not system, but yesterday in the examination of the Linux database is still encountered a lot of problems and confusion, and by the way to review the relevant knowledge.First look at the situation of the disk: Df-kFile system 1k-block already used% mount point available/dev/mapper/vg_sspdb1-lv_root51606140 2754580 46230120 6%/Tmpfs 32984140 0 32984140 0%/dev/shm/DEV/SDA1 495844 38042 432202 9%/boot/dev

Debug Notes:First step: Read the physical sector 0.The four bytes starting from offset 0X1CA (458) are: 0x7,0x5b,0x1e,0x00;And the number of sectors is: 0x1e5b07=. Each sector is 512 bytes. So the SD card capacity is: *512/1024/1024mbyteThe 4 bytes starting from offset 0x1c6=454 are: 0xf9,0x00,0x00,0x00, which indicates that the boot sector is in the 0xf9=249 sector.

In practical applications, when we are ready to hand over a project to the customer for use, we need to clear all the tables in the library before the test data to give the customer a clean database, if the table involved a lot, to be emptied, not only time-consuming, but also error-prone and omitted, here I provide a method, Can quickly and efficiently empty the data for all tables in the specified database. For reference only, please exchange different views. --remove all data from a database

Linux disk and file system management It is still important for disks and file systems, because all the data is stored in the disk. The correct partition of the disk and the management of the file system are summarized in my own notes, we hope you can provide more support. I. Disk and partition management tools Hard Disk Representation For example,/dev/sdb2/dev is the directory where all hardware information is stored. sd represents the disk/USB device of the SCSI interface (hd represents the

One day, Win8.1 cannot be used normally. I want to reinstall Win8.1, but Linux cannot be booted into after installation! We all know that Grub is used for guidance in Linux, so we can reinstall Grub! Because the original Linux cannot be accessed, we create a Linux system installation disk and use "Try Ubuntu
