Just starting out and have a question? Notices Welcome to LinuxQuestions. You are currently viewing LQ as a guest.
If you want a review of file systems, be sure to check out our other article, HTG Explains: In the old days, it was the primary way that the system mounted files automatically. Back then, your only alternative was the tell the computer that anytime a specific device was plugged in, it should be automatically mounted in a specific place.
This is where fstab came in, and it was awesome. The computer could load the file systems in a different order, potentially messing things up. Fstab is configured to look for specific file systems and mount them automatically in a desired way each and every time, preventing a myriad of disasters from occurring.
Your Fstab File The fstab file is located at: Each file system, during formatting, gets assigned a Universally Unique Identifier, which it takes to the grave.
Since it cannot be changed, this is the ideal way to select file systems for mounting, especially for important ones.
If you switch to or are stuck using the old method of using device identifiers to select partitions i.
Using UUIDs in your fstab file, while convenient for most home users, does have a few big caveats. The next section of fstab, like all subsequent ones, is separated by either a space or a tab, or a combination of them. Next is the section which identifies the type of file system on the partition.
Your particular system may still need to have particular packages installed to be able to read and write to them.
The default option is first, followed by alternatives, but as Linux distros can be very different, your mileage may vary. Specify whether the partition should be automatically mounted on boot.
Specifies whether the partition can execute binaries. This one is interesting.
This allows the user to have mounting and unmounting privileges. These options are separated by a comma and no spaces, and can be put in any order. You can see that my two storage drives have user mounting privileges enabled, read-write access enabled, and auto-mounting is turned on.
Always remember to make a backup in case something goes wrong, but have fun, and be sure to leave your experiences in the comments!I know that question is outdated, but saw it, because nowadays got in the same trouble. I broke my fstab manually (make a typo in parameter)..
That was very easy to correct fstab from readonly mode. We must mount / in read-write mode..
|mount: block device is write-protected, mounting read-only||Originally Posted by MeeLee I've got a similar problem, but I don't think it's because of the service start up order.|

If /etc/fstab is correct, you can simply type. mount -n -o remount /. While making an entry in fstab, a mount point is to be created before rebooting (as changes take effect after restarting).
ro is for read-only partition while rw denotes read-write partition. To be able to write on a partition, it should have rw option in fstab file. • user/nouser. With nouser as an option. Mounting and Unmounting File Systems; Mount all the file systems listed in /etc/fstab, or the revocation of write access when downgrading a file system's mount status from read-write to read-only.-r.
Mount the file system read-only.
I've a VirtualBox VM which configured a very large hard disk size (bigger than host). By my mistake, a program on the VM generated lots of log files and the VDI file size keeps growing until there. On the client we can decide that we don't want to trust the server too much a couple of ways with options to mount. For example we can forbid suid programs to work off the NFS file system with the nosuid option. Some unix programs, such as passwd, are called "suid" programs: They set the id of the person running them to whomever is the owner of the file. I haven't rebooted this computer yet (it is a production machine), but I'm trying to figure out the fstab options to accomplish the `kaja-net.com -o rw,user=*,password=* ` function. Can Linux even mount via fstab using the cifs filesystem?
This is. Don't use common admin account names for the grub2 superuser. Avoid using common admin account names like, root, admin or administrator for the grub2 superuser account. On the client we can decide that we don't want to trust the server too much a couple of ways with options to mount.

A few years ago I have set the mount point's group to the plugdev group, added the user to that group. This way, by creating new groups, it is possible to give permissions on a per user basis.
