I'm having problems with automatically mounting my HDD using fstab entry.

In my fstab I added the following entry:

/dev/disk/by-uuid/CE20D46C20D45D51 /mnt/data1 auto default,exec,dev,suid 0 0

Whenever I try to remount it I get (from reading /proc/mounts):

/dev/sda1 /mnt/data1 fuseblk rw,nosuid,nodev,relatime,user_id=0,group_id=0,allow_other,blksize=4096 0 0

The problem is that I need to have dev and exec enabled, but this is not working whatever options I add or remove from my fstab entry. Any ideas?

EDIT:

Linux: Linux Mint Mate 17.2 Rafaela

Kernel version: Linux version 3.16.0-38-generic

File System: fuseblk (ntfs)

dmesg doesn't show any messages after performing following commands:

sudo umount /dev/sda1
sudo mount -a

in /var/log/syslog I can find:

    Unmounting /dev/sda1 (Data1)
    Version 2013.1.13AR.1 external FUSE 29
    Mounted /dev/sda1 (Read-Write, label "Data1", NTFS 3.1)
    Cmdline options: rw
    Mount options: rw,allow_other,nonempty,relatime,fsname=/dev/sda1,blkdev,blksize=4096
    Ownership and permissions disabled, configuration type 7

EDIT2:

My full fstab file:

# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).
#

/dev/disk/by-uuid/CE20D46C20D45D51 /mnt/data1 auto users,exec,dev,suid 0 0
/dev/disk/by-uuid/2A6AD5C96AD59245 /mnt/data2 auto suid,exec,dev,nofail,x-gvfs-show 0 0

EDIT3:

Remounting it using:

mount -o remount,exec,dev /mnt/data1

Seems to work, but why doesn`t this work using fstab? I want this to happen automatically.

  • is there a virtualization or container or selinux ? after the mount, can you cut and post the last lines of dmesg and /var/log/messages ?

    Remounting using: mount -o remount,exec,dev /mnt/data1 seems to work, but it why can't I auto mount it this way? Aug 26, 2016 at 12:06

Unfortunately this (mounting NTFS with suid and dev options from fstab) may not possible without modifying NTFS-3G or mount(8).

The problem is, the mount(8) program doesn't pass dev, suid and some other default options to related helper program, in this case /sbin/mount.ntfs; because they are considered default. These options should be effective and works if you are using the mount helper program directly: mount.ntfs -o exec,dev,suid /dev/disk/by-uuid/CE20D46C20D45D51 /mnt/data1

The workaround I recommended is to modify NTFS-3G to remove the default nodev and nosuid.
