The Linux system may have created different partitions on the disk for Boot, EFI, root, swap, and home. These partitions are indicated by a number at the end of the “disk name” such as /dev/sda1, /dev/nvme0n1p2, etc. It is also possible to determine which partition is used for...
To liberate disk space in Linux, begin by pinpointing the files or directories consuming the most storage. The du command can help you evaluate the space usage of particular directories. Once you have identified the directories or files that use a lot of disk space, you can delete, move, or...
*/ atomic_t _mapcount; /* * If the page is neither PageSlab nor mappable to userspace, * the value stored here may help determine what this page * is used for. See page-flags.h for a list of page types * which are currently stored here. */ unsigned int page_type; unsigned int ...
The du command shown earlier displays the top 10 largest directories in the current folder. These may contain expendable files or subdirectories that can be deleted to free up disk space. Review the output and determine if any directories are good candidates for removal. Things like temporary fil...
User space start CPU检查 内存检查 设备总线发现 设备发现 辅助内核子系统设置(网络等) 挂载根文件系统 用户空间启动 The first steps aren’t too remarkable, but when the kernel gets to devices, a question of dependencies arises. For example, the disk device drivers may depend on bus support and ...
The ecs-user directory consumes the largest amount of disk space. You can further check the specific files or subdirectories in the ecs-user directory to determine which items consume a large amount of sace. Repeat the preceding process. In this example, you can find a large number ...

If the process remains in non-sleeping state for a long period, you can preliminarily determine that the system is consistently paging. In such a case, the high CPU usage is caused by insufficient memory. Run the vmstat command to check the virtual memory usage of the system. If the si...
Now we determine the new end sector for our partition. Well need to verify numbers and calculate it: lvm pvs –units g( VolGroup PSize / PFree is 643.00g / 457.00g ) lvm pvs –units s( VolGroup PSize / PFree is1348460544S/ 958390272S ) ...
This section describes how you can configure atop and kdump on Linux ECSs for performance analysis. The method for configuring atop varies with the OS version. atop Introduction to atop Preparing for atop Installation Configuring atop for CentOS 7/8, AlmaLinux, and Rocky Linux Configuring atop for...
