When you run the mount command without any argument that display mounted file systems, including the virtual file systems such as cgroup, tmpfs, devpts, debugfs, etc. If so, you should kill the process to unmount the filesystem. The most common problem is that the file system is busy, which is currently used by some processes. Unmounting the file system is not always successful. The umount command is used to manually unmount (detaches) filesystems on Linux and other Unix-like operating systems.Īll mounted filesystems are unmounted automatically when a system shuts down. This is commonly used to incorporate the changes that you made on a filesystem. remount : This remount an already-mounted filesystem._netdev : This allows the system to mount the file system only after the network is enabled.nodev : Do not interpret character or block special devices on the file system.nosuid : To ignore set-user-identifier (SUID) or set-group-identifier (SGID) bits in the file system.noexec : Ban execution of any binaries on the loaded file system.noauto : File systems set with the option noauto in the file /etc/fstab are not mounted automatically when the system boots.async : All I/O to the filesystem should be done asynchronously (It’s used default).This default option uses the following options such as rw, suid, dev, exec, auto, nouser, async, and relaime in the mounted file system. defaults : You may have seen that most of the mounted file systems have default options in the “/etc/fstab” file.Mount īelow are some options you can use when mounting the filesystem. The general syntax for mounting a file system mount. The mount command is used to attach (mount) filesystems and removable devices such as CDRM, DVD, USB flash drives to a specific mount point in the directory tree.Īll mentioned filesystems in the “/etc/fstab” file will be mounted automatically when a system boot. The mount and umount programs maintain a list of currently mounted filesystems in the “/etc/mtab” file. Once you have done the above steps, you can mount the partition (a directory) into a mount point using the mount command. You will be not able to use any disk on Linux system without a filesystem because the file system contains information about files and directories.

Once you have created partitions, you must create a file system using the mkfs command on disk space. When adding a new hard disk to your system, you may need to use the fdisk command or the parted command to create partitions.

In order to solve this we perform a full reboot, and now the disk is write/read as it should be. This is very strange, how the disk device became write protected? So we do not have a choice and we perform a reboot.Īnd from history we do not see that someone limited the disk for read only by mount. In spite the /etc/fstab allow read and write and all sub folder under /grop/sdc have full write/read permissions: /dev/sdc /grop/sdc ext4 defaults,noatime 0 0Īnd from df -h, we see that the disk is currently not mounted. We get write protected error like: /dev/sdc read-write, is write-protected When we perform: mount -o rw,remount /grop/sdc And the filesystem for device /dev/sdc is ext4.
