I just recover my /etc/fstab file using THIS

But after reboot it says:

Mount failed press S to skip and M to mount manually. on S it skip all services and just start with mount only default drive

on this system /etc/fstab looks like this. which i generated now.

UUID=e8008245-01d3-4df3-b409-8036ad7cd0d0 / ext4  default    0     2
UUID=ff122186-e22b-4ba6-a8fc-36ef76150bea / ext4  default    0     2
UUID=81aa6aad-9d95-4f48-aa68-cf2b4a23f4aa / ext4  default    0     2
UUID=7f83f0bf-31b0-4977-97ed-a40d6c8c0c9a / ext4  default    0     2
UUID=4e8e58d8-ef0b-4ebd-8403-8fc81d3121f1 swap

what mistake i am doing in above file? What other option do we have to use rather than "Default" or mount except '/'. I have tried doing.

/boot, /, /sda2, /sda1. it give erros like:

  • unrecognized mount option "default" or missing value
  • mountall: mount /dev/sda5 [725] terminated with status 32
  • mountall: filesystem counld not be mounted: /dev/sda5

Running command: lsblk -o NAME,FSTYPE,UUID

    The obvious one: You have four different partitions being mounted to the same mount point (and to /, at that). I'd guess that at least one of those partitions doesn't exist. – muru Nov 06 '14 at 07:53
  • on sudo blkid it shows five UUID drives it means it have four partitions and one swap memory. Do i have to change mount point like /dev/sda1,/dev/sda2,/dev/sda3,/dev/sda4 ? – Sarz Nov 06 '14 at 07:56

    You may have five partitions, but nobody has five partitions mounted on root. Perhaps one of those is an LVM member. What's the output of sudo lsblk -o NAME,FSTYPE,UUID? – muru Nov 06 '14 at 07:58
  • This is the output: NAME FSTYPE UUID sda ââsda1 ââsda2 ââsda3 ââsda5 ââsda6 ââsda7 sr0 – Sarz Nov 06 '14 at 07:59
  • Now with sudo, Edited – Sarz Nov 06 '14 at 08:21
  • Interesting. All of them exist and are ext4 partitions. Now try with an fstab containing only one of them (comment out lines of the others). Repeat until you get the right root. – muru Nov 06 '14 at 08:23
  • I know my root directory its: ff122186- – Sarz Nov 06 '14 at 08:29
  • Ok, then don't mount the other partitions at /. Remove their lines, or mount them at other directories, like /media/something. – muru Nov 06 '14 at 08:32
  • Do i have to write deafult 0 1 ? – Sarz Nov 06 '14 at 08:35

Since 7f83f0bf-31b0-4977-97ed-a40d6c8c0c9a is the root partition, mount only it on /, so your fstab will look like this:

UUID=7f83f0bf-31b0-4977-97ed-a40d6c8c0c9a / ext4  errors=remount-ro    0     1
UUID=4e8e58d8-ef0b-4ebd-8403-8fc81d3121f1 swap

Ubuntu uses errors=remount-ro for / by default, and it is helpful in keeping the system running, but preventing future damage, if there disk errors.

And according to man fstab:

   The sixth field (fs_passno).
          This field is used by the fsck(8) program to determine the order
          in  which  filesystem  checks are done at reboot time.  The root
          filesystem should be specified with a fs_passno of 1, and  other
          filesystems  should have a fs_passno of 2.

So the last number should be 1 for /.
