is a high risk that when a file is opened in linux, the Linux kernel creates a directory named "pid" for each process in/proc/"/proc/nnnn/fd/Directory (nnnn is pid)" to save the process information, the sub-directory fd stores the fd (fd: file descriptor) of all files opened by the process ). By truncating files in the proc file system, the kill process forcibly requires the system to recycle the files allocated to being used. This is an advanced tec

disk of the virtual machine is found to be 16 GB, but after entering the Linux system, use "DF-h" to check whether the hard disk space is as large as originally. Although the disk has been expanded, the Linux operating system cannot be identified because the file system has not been partitioned. [Root @ centos2 ~] # F

For ease of development and commissioning, an Ubuntu 12.04 virtual machine was installed with VirtualBox to run hive and Hadoop inside. A problem was found during use, running some query in hive, and after a while, the virtual disk space grew rapidly, reaching dozens of G. The virtual disk itself is configured for dynamic growth mode, but the physical

contains metadata called "I node inode", which is used to save information about the file. The number of I nodes in many file systems is fixed, so it is likely that I nodes are exhausted and the file system is not used up yet. You can usedfTo check. sudodf-i / Compare the number of I nodes used and the total number of I nodes. If no I node is available, unfortunately, you cannot expand the I node. Delete useless and expired files to release some I
