mount命令 用于加载文件系统到指定的加载点。此命令的也常用于挂载cdrom,使我们可以访问cdrom中的数据,因为你将光盘插入cdrom中,Linux并不会自动挂载,必须使用Linux mount命令来手动完成挂载。 Linux系统下不同目录可以挂载不同分区和磁盘设备,它的目录和磁盘分区是分离的,可以自由组合(通过挂载) 不同的目录数据可以跨越不同的磁盘分区或者不同的磁盘设备 磁盘设备默认没有入口,不能访问磁盘的入口是挂载点。 挂载的实质是为磁盘添加入口 mount常见命令参数 The standard form of the mount command, is mount -t type device dir -l:显示已加载的文件系统列表; -h:显示帮助信息并退出; -v:冗长模式,输出指令执行的详细信息; -n:加载没有写入文件“/etc/mtab”中的文件系统; -r:将文件系统加载为只读模式; -a:加载文件“/etc/fstab”中描述的所有文件系统。</PRE></BLOCKQUOTE> -t: 加载文件系统类型 supported include: adfs, affs, autofs, cifs, coda, coherent, cramfs, debugfs, devpts, efs, ext, ext2, ext3, ext4, hfs, hfsplus

Linux下mount存储盘遇到的错误

别等时光非礼了梦想. 提交于 2019-11-27 21:02:35
一、注意点 二、解决过程 1、错误截图 错误描述: 报出磁盘已经挂载或挂载目录忙 2、分析过程 (1) 把报错的这个盘和目录umount,重新挂载,还是不行 (2)查看磁盘的分区格式,发现不是GPT的(新加磁盘挂载的是存储上的,大小1T) 3、解决办法 注: 对挂载的磁盘重新分区,并初始化为GPT格式,重新挂载 (1)重新分区,初始化 命令:parted /dev/mapper/mpatha mklabel gpt 格式化为gpt mkpart patimary 0% 50% 创建一个主分区(使用一半空间) (2)初始化分区   命令:mkfs.ext4 /dev/mapper/mpatha1 (3)重新mount,成功   命令:mount /dev/mapper/mpatha1 /sqldata (4)添加自动挂载   命令: vi /etc/fstab 大功告成! 来源: https://www.cnblogs.com/jialanyu/p/11376611.html

Check if directory mounted with bash

时光怂恿深爱的人放手 提交于 2019-11-27 19:48:36
问题 I am using mount -o bind /some/directory/here /foo/bar I want to check /foo/bar though with a bash script, and see if its been mounted? If not, then call the above mount command, else do something else. How can I do this? CentOS is the operating system. 回答1: Running the mount command without arguments will tell you the current mounts. From a shell script, you can check for the mount point with grep and an if-statement: if mount | grep /mnt/md0 > /dev/null; then echo "yay" else echo "nay" fi

How to mount a USB drive on Android Things?

问题 I'm attempting to read files off of a USB drive for an Android Things app on a Raspberry Pi . I'm able to scan the list of mounted devices like so: public static List<File> ScanForFiles(Context context){ ArrayList<File> files = new ArrayList<>(); try{ BufferedReader reader = new BufferedReader(new FileReader("/proc/self/mountinfo")); String line; while ((line = reader.readLine()) != null) { String[] columns = line.split(" "); Log.i(TAG, "Mounted: " + columns[4]); //files.addAll(getListFiles

问题 I'm writing an android app that needs to copy a file to the "/system" partition at runtime. I've got the commands to run "su" and can successfully request SuperUser permissions and run commands as root. But I don't know how to make this app universal across multiple devices, because the mount command can differ depending on where the /system is actually mounted. Here's the command that's used most offen: mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system But I know that mtdblock3

Docker入门-数据挂载

Docker数据管理 在容器中管理数据主要有两种方式: 数据卷(Volumes) 挂载主机目录(Bind mounts) 数据卷 数据卷是一个可供一个或多个容器使用的特殊目录,它绕过UFS,可以提供很多有用的特性: 数据卷可以在容器之间共享和重用 对数据卷的修改会立马生效 对数据卷的更新,不会影响镜像 数据卷默认会一直存在,即使容器被删除 注意: 数据卷的使用,类似于Linux下对目录或文件进行mount,镜像中的被指定为挂载点的目录中的文件会隐藏掉,能显示看的是挂载的数据卷。 Docker中提供了两种挂载方式,-v和-mount Docker新用户应该选择 --mount参数 经验丰富的Docker使用者对-v或者--volume已经很熟悉了,但是推荐使用-mount参数。 创建一个数据卷 docker volume create my-volume 查看指定数据卷的信息 docker volume inspect my-volume 启动一个挂载数据卷的容器: 在用docker run命令的时候,使用--mount标记来将数据卷挂载到容器里。 创建一个名为session-web的容器,并加载一个数据卷到容器中的/webapp目录。 # 方法一 docker run --name session-web -d -p 8888:8080 --mount source=my

Linux function to get mount points

試著忘記壹切 提交于 2019-11-27 14:04:51
Is there a function (or interface; ioctl, netlink etc) in the standard Linux libs that will return the current mounts directly from the kernel without parsing /proc? strace ing the mount command, it looks like it parses files in /proc Please see the clarification at the bottom of the answer for the reasoning being used in this answer. Is there any reason that you would not use the getmntent libc library call? I do realize that it's not the same as an 'all in one' system call, but it should allow you to get the relevant information. #include <stdio.h> #include <stdlib.h> #include <mntent.h> int
