Introduction to fstab

Programs such as pmount allow ordinary users to mount and unmount filesystems without a corresponding fstab entry; traditional Unix has always allowed privileged users the root user and users in the wheel group to mount or unmount devices without an fstab entry.

You may use "defaults" here and some typical options may include: Examples The contents of the file will look similar to following: You can find a discussion of relatime here: This is also a default setting. Default settings are defined per file system at the file system level. However, some administration tools can automatically build and edit fstab, or act as graphical editors for it, such as the Kfstab graphical configuration utility available for KDE.

Some file systems such as XFS enable acls by default. The normal default for Ext3 file systems is equivalent to rw,suid,dev,exec,auto,nouser,async no acl support.

For mounting samba shares you can specify a username and password, or better a credentials file. With noauto, the device can be only mounted explicitly. The space- or tab-separated fields within each row typically aligned in columns, as above, but this is not a requirement must appear in a specific order, as follows: Equivalent to rw, suid, dev, exec, auto, nouser, async.

Options are dependent on the file system. The more modern ext4 supports larger volumes along with other improvements, and is backward compatible with ext3. If nouser is specified, only root can mount the filesystem.

Looking at the example fstab, this is the option used with the floppy. Often a source of confusion, there are only 3 options: Missing values in the last two fields are interpreted as zeros. You may also "tune" or set the frequency of file checks default is every 30 mounts but in general these checks are designed to maintain the integrity of your file system and thus you should strongly consider keeping the default settings.

Modern Red Hat based systems set acl support as default on the root file system but not on user created Ext3 file systems. Only valid with fstype nfs. The main difference between ext2 and ext3 is that ext3 has journaling which helps protect it from errors when the system crashes.

Listed below are some of the more commonly used.

One result is that atime is written every time a file is read, which has been heavily criticized for causing performance degradation and increased wear. This means that when, for example, a file is copied to the floppy, the changes are physically written to the floppy at the same time copy command is issued.

Dump is seldom used and if in doubt use 0. Instead it is written by the system administrator or sometimes by an operating system installation program. This automatically implies noexec, nosuid, nodev unless overridden. You can do this on Music and Movies to access these files from Ubuntu.

You must explicitly mount the filesystem. For ext3 file systems these can be set with the tune2fs command. Note that these are for Linux; traditional UNIX-like systems have generally provided similar functionality but with slightly different syntax. If users is specified, every user in group users will be able to unmount the volume.I am trying to get it to mount automatically on reboots using the following line added to /etc/fstab /dev/sdb1 /media/workspace auto defaults 0 1 This works to auto mount it, however I would like to restrict read/write access to users belonging to a specific group.

Modify fstab entry so all users can Read and Write to an EXT4 Volume namely, rw so any user can read/write. Unfortunately, the fstab entry does not work. It mounts fine, but it by creating new groups, it is possible to give permissions on a per user basis.

For home usage, it's enough to set mount point permissions to others: read/write. I have access to a cifs network drive. When I mount it under my OSX machine, I can read and write from and to it. When I mount the drive in ubuntu, using: sudo mount -t cifs -o username=${USER}.

The fstab file is read by the mount command, which happens automatically at boot time to determine the overall file system structure, and thereafter when a user executes the mount command to modify that structure. Mount the. If you don't want to manually edit anything, there are utilities that can be installed using either Ubuntu's built-in software centre or the package manager that will allow you to configure drives to automount and set the permissions for read/write and mount/unmount.

Repairing fstab (read only /) Ask Question Maybe a -n is necessary, maybe not. That should remount the root fs read/write (assuming there's nothing wrong with it). share e on the entry you want edit will allow you to edit the arguments given to the kernel), and it will mount your root file system not read only anymore.

Then you can.
