fstab editing

korn_16_f_t_l · 03-20-2016, 09:53 PM

so i have got my server up and running and my 3TB hdd is shared over my network over samba, now comes streaming media via plex as well as a few other minor detail such as the second hdd not auto mounting on restart.

so i have been reading about editing my fstab file so that devices automatically mount on boot this subject first came up when searching why i can not find any sub directories in Plex while using the browse option to set up libraries (see article here: http://ubuntuforums.org/showthread.php?t=2087341 )

i attempted to edit my fstab and i had horrible results i had to remove the add'd line so i must have done something wrong, what im hoping for is that someone can help me write the line that i do need to add in the fstab so i dont make this error again.

according to the site i was reading (see here: http://askubuntu.com/questions/16492...n-ubuntu-12-04 ) i need a few things

Code:

UUID=<uuid> <pathtomount> <file system> uid=<userid>,gid=<groupid>,umask=0022,sync,auto,rw 0 0

so i obtained most if not all of the information

Code:

/dev/sda1: UUID="2bd1c8c3-2e6e-433c-ab3c-d5311b98bcd3" TYPE="ext4" 
/dev/sda5: UUID="a53e2978-0c37-438f-a799-60c934be68e6" TYPE="swap" 
/dev/sdb1: LABEL="Network Storage" UUID="686f24ec-b686-4dda-b4b6-0a69a2d6602e" TYPE="ext4"

now

Quote:

/dev/sdb1: LABEL="Network Storage" UUID="686f24ec-b686-4dda-b4b6-0a69a2d6602e" TYPE="ext4"

is the device i would like to auto mount on boot up with the following path (whats displayed in the dolphin property's for the HDD's root directory)

Quote:

/media/korn16ftl3/Network Storage/

my user id is

Quote:

korn16ftl3@UBUNTU:~$ id -u korn16ftl31000

my group ID is as follows:

Quote:

korn16ftl3@UBUNTU:~$ id --groups1000 4 24 27 30 46 107 113

now if im following the instructions correctly the line i need to add should be something like this

Code:

UUID=686f24ec-b686-4dda-b4b6-0a69a2d6602e /media/korn16ftl3/Network Storage/  type=ext4 uid=1000,gid=1000 4 24 27 30 46 107 113,umask=777,sync,auto,rw 0 0

i have no idea what a umask is but in a quick google search it said it assigns read and write permissions.....personally seeing as how this drive is also my samba drive as well as where my media is stored i would like read write and execute privileges to it when it is auto mounted.

so what im looking for is is this peice of code ready to copy and paste right to my fstab file? what would you guys change about it? i didnt do anything crazy that will screw something up like to many spaces or anything did i?

i have been known to not have correct linux punctuations shall we call it? before where to many spaces screwed me up every time in the CLI

This link helped me when I started to use UUIDs in /etc/fstab. http://www.cyberciti.biz/faq/linux-f...-update-fstab/

I'm no expert, just a hobbyist, but I think that you can use a label or a UUID in /etc/fstab, but not both.

gid=1000 4 24 27 30 46 107 113

i think that part is incorrect, but im guessing.

Only one group can be given here. The mounted disk will belong to the user and group specified, like any file does. Do an ls -l in any directory and you will see what I mean. Each file belongs to one user and one group. If you want the disk to belong to you, it's easiest to use your login group. But in practice you seldom need to give these options; the default ones usually work just fine.

A umask is simply a mask which determines the default permissions of any new files created on the disk.

additionally you should not specify mount directory containing space, you will have difficulties (/media/korn16ftl3/Network Storage/)

Several problems:

The uid, gid, and umask options do not apply to Linux native filesystems like ext2/3/4. They are for filesystems like FAT that don't support Unix-style ownership and permissions. To set ownership and permissions in ext2/3/4 filesystems, use chown, chgrp, and chmod while the filesystem is mounted.
As was mentioned before, you should not use both LABEL and UUID. Use one or the other.
The fstab format does not support quoted strings. The quote characters will be taken literally. To represent a space character, use its octal escape %040.

so what should i actually input into the CLI to get the hard drive to mount automatically when the computer boots up?

for example, but you should know what do you really need:
UUID=686f24ec-b686-4dda-b4b6-0a69a2d6602e /media/korn16ftl3/Network_Storage/ type=ext4 sync,auto,rw 0 0
take care about that space (replaced to _)

I don't think you want that "type=" there. Also, if this is an external drive, I suggest including the "nofail" option so that the machine will still boot even if the drive is not present or fails to mount for some other reason. And, the "auto" and "rw" options are the default, and so need not be included.

Code:

UUID=686f24ec-b686-4dda-b4b6-0a69a2d6602e /media/korn16ftl3/Network_Storage ext4 sync,nofail 0 0

Or, if you really, really want that space in the directory name:

Code:

UUID=686f24ec-b686-4dda-b4b6-0a69a2d6602e /media/korn16ftl3/Network%040Storage ext4 sync,nofail 0 0

yes, you are right, that was my mistake. sorry
