This section describes how to reclaim space and then use it for new services if all or some services of a storage system are not required anymore, or some expanded space is unnecessary in a Linux operating system, thereby enhancing storage space utilization. Preparing for Space Recla...
During an expansion, the additional space is added to the end of the disk. If the disk has multiple partitions, the additional space can only be allocated to the partition at the disk end. If a disk uses MBR, the storage space in excess of 2 TiB cannot be used because the maximum cap...
[root@centos8 ~]#echo -e 'n\np\n\n\n+2G\nt\n82\nw\n' | fdisk /dev/sdc [root@centos8 ~]#mkswap /dev/sdc1 Setting up swapspace version 1, size = 2 GiB (2147479552 bytes) no label, UUID=d3140a7a-65b7-4cb7-8a2b-12d38aa98c6f [root@centos8 ~]#blkid /dev/sdc1 /dev/...
Before reclaiming space, you must finish preparatory work such as backing up disk information and checking the host's and storage device's running status to ensure that the space reclamation can be successfully implemented. Procedure Confirm the range of to-be-reclaimed storage space and...
常见的闪存类块设备是在个人计算机和笔记本电脑上使用的固态硬盘 splid State Drives,SSD),以及在手机和平板电脑上使用的嵌入式多媒体存储卡(embedded Multi Media Card,eMMc)和通用闪存存储(Universal Flash Storage,UFS)。闪存类块设备相对机械硬盘的优势是:访问速度快,因为没有机械操作:抗振性很高, 便于携带。

You’ll see the basic workings of how the kernel sends a message to a user-space process through udev, as well as what the process does with it. 当系统接收到新设备时,了解内核与用户空间的交互方式非常重要。 udev系统使得用户空间程序能够自动配置和使用新设备。 您将会了解到内核如何通过udev向...
1、Userspace Direct I/O Userspace Direct I/O(用户态直接 I/O)技术的底层原理由 Kernel space 中的 ZONE_DMA 支持。ZONE_DMA 是一块 Kernel 和 User Process 都可以直接访问的 I/O 外设 DMA 物理内存空间。基于此, Application 可以直接读写 I/O 外设,而 Kernel 只会辅助执行必要的虚拟存储配置工作,不...
