How do I automount usb drives on server?
 
I'm trying to use usb drives for samba shares on my server. Having lots of problems but I feel like it's because the drives aren't mounting. This is on Centos 6.5. I just logged onto the gui and one drive popped up eventually and the other I had to mount through disk management. They both mount to /media and that's the path I'm using in my smb.conf and I can't connect to the shares but I feel like this is the problem that they are not mounted unless I log onto the server and then they auto mount after a long delay or I manually mount them. When the server is idle with no log on I imagine the drives are not mounted. Can I just edit fstab to add them?

How do I determine if the mount issue is my problem? When I mount a drive in the gui it is mounted /media/backup. I can access the drive through the gui and it's fine.

Now I am ssh into the server. I
Code:
cd /media
and then ls and I see backup listed. I can cd again to /backup but when I ls at this point I get no results. That makes me assume that the volume is not really mounted. I should be able to see the contents of the drive when I ls , correct?

I tried
Code:
mount /media/backup
and get:

Code:
[mntent]: line 6 in /etc/fstab is bad
mount: can't find /media/backup in /etc/fstab or /etc/mtab
If i try to mount the smb share on my laptop using Nautulis it gives me this prompt (see attachment). I enter my password which I set on the server by doing

Code:
smbpasswd -a ryan
when I enter the password in Natuilus , I get:


Unhandled error message: Failed to mount Windows share: Permission denied


My smb config looks like this:


[backup]
path = /media/backup
valid users = ryan
read only = No
guest ok = Yes
available = yes
browsable = yes
create mask = 0777
directory mask = 0777


The frustrating thing is I had this working before with the same drive and same settings on this server. I have since reintalled the OS to start from scratch but set everything up the same

Check out my 1 blog entry for NTFS-related issue/help. ;)

quick update. I am using samba swat to manage the shares to make it as easy as possible. I just added myself to the admin group for the shares and I can mount the share but the folder is empty.

That leads me back to believing that the actually usb drive is not mounted properly on the server.

I will check it out. The usb drives in question are actually formated ext4

Habitual 02-13-2014 04:02 PM
Sorry about "that". I assumed NTFS for "some reason". :(

Make a
Code:
sudo /media/some_directory
and try mounting it manually first with
Code:
sudo mount -t auto /dev/sdXn    /media/some_directory
or possibly (not default)
Code:
sudo mount -t ext4 /dev/sdXn    /media/some_directory
if that works, then
Code:
/dev/sdXn        /media/some_directory          ext4        defaults        1  2
would be the /etc/fstab entry.
if you mounted it manually already

in terminal as root (or sudo) you can test the /etc/fstab using
Code:
sudo umount /media/some_directory
and then
Code:
sudo mount -a
/dev/sdXn <-- yours will be different.
Do you know how to find that out?

Let us know!

I don't know how to find that out. I know I can browse /dev but other then that I'm not sure. I know my usb drive should show up as sdb or sdc or something like that but I'm not sure how to determine which drive is which

Plug the drive in (automount is ok if it does this)
and open terminal and type
Code:
mount | grep sd
or mount through disk management then "mount | grep sd"

show us the output.

My "/media/some_directory" example is "/media/backup" in your case.

I figured out that much ;-) thanks for the help!

Is it now working?

I'm at work now so I don't have access to my server to test. I will report back once I am able to test

Habitual 02-13-2014 06:06 PM
sure thing!

Subscribed with interest....

When I run this command I get:

Code:
/dev/sdc1 on /boot type ext4 (rw)
I have 2 usb drives connected and I am guessing sdc1 is the internal boot drive on the computer.

When I :
Code:
lsusb
it returns:

Code:
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
Bus 002 Device 005: ID 152d:2329 JMicron Technology Corp. / JMicron USA Technology Corp. JM20329 SATA Bridge
Bus 002 Device 006: ID 1058:0704 Western Digital Technologies, Inc. Passport External HDD
I know the last two devices are the usb drives. Can I mount them with any of that info?

Code:
lsblk
ls -l /dev/disk/by-uuid
would be more appropriate. it will tell you everything plugged in and its /dev/locations. if they aren't mounting automatically then /etc/fstab is the way to go. do it by uuid though, just today i restarted my computer and my flash drive and usb hdd swapped /dev locations. uuid that can't happen.
