UUID is a property of disk partitions used to identify them uniquely. Here are various ways to get the UUID of a disk partition in Linux.
To generatetime basedUUID, run: uuidgen -t Use the commanduuidgenwith the option-rto generate random UUID. uuidgen -r To generate hash based UUID use --md5 or --shal with --namespace <namespace>. Conclusion In this tutorial, we learned how to generate UUID in Linux.Finding UUIDin Lin...
Based on the filesystem type we have few tools to change UUID. Linux utilities such as tune2fs(for ext2 or ext3 or ext3), xfs_admin (for xfs), btrfstune (for btrfs) can be used to change UUID. In this example, I have used disk /dev/sdb to change the UUID and will use tune...
To solve this problem, most modern Linux systems use the Universally Unique Identifier (UUID, see 4.2.4 Filesystem UUID) for persistent disk device access. 不幸的是,这种设备分配方案在重新配置硬件时传统上会导致问题。 例如,假设您有一个带有三个磁盘的系统:/dev/sda、/dev/sdb和/dev/sdc。 如果/...
为了解决这个问题,大多数现代Linux系统使用通用唯一标识符(UUID,参见4.2.4节的文件系统UUID)进行持久磁盘设备访问。 This discussion has barely scratched the surface of how to use disks and other storage devices on Linux systems. See Chapter 4 for more information about using disks. Later in this chapte...
Find partition UUID using tune2fs Atune2fscommand utility manages various filesystem parameters on Linuxext2,ext3, andext4filesystem, which even shows the current status of the disk. You can runtune2fswithgrepcommand to filter out the UUID information to get the UUID. And please change the...

为了访问磁盘上的数据,Linux内核使用了图4-2所示的层次系统。 SCSI子系统和3.6深入解析:SCSI和Linux内核中描述的其他内容都由一个单独的框表示。 (请注意,您可以通过文件系统以及直接通过磁盘设备来处理磁盘。 在本章中,您将两者都会遇到。) To get a handle on how everything fits together, let’s start at...
Change UUID of Linux Partition Follow the below steps to change the UUID of Linux Partition. 1. Run the below command to find out UUID of the devices. # blkid /dev/mapper/centos_centos71-root: UUID="2bc8e0d4-64b5-4dc8-bf4a-024fc980d98a" TYPE="ext4" ...
Linux x86GoalIn Linux, sometimes the name of devices or file systems are not persistent which will bring system in trouble, in such situation specify UUID (universally unique identifier) is the solution to identify the only unique component in the system....
