Are These Two Mount Statements The Same

I am installing VirtualBox on Centos per http://www.digitesters.com/centos-in...adless-system/, and I don't understand the very end. Seems like Line 5 is not needed as it is already done on Line 4, right?

Code:

# mkdir /data/virtual_machines/vbox/vbusbfs
# chown vboxuser.vboxusers /data/virtual_machines/vbox/vbusbfs
# chmod 775 /data/virtual_machines/vbox/vbusbfs
# echo "none /data/virtual_machines/vbox/vbusbfs usbfs rw,devgid=$(awk -F : '/vboxusers/ {print $3}' /etc/group),devmode=664 0 0" >> /etc/fstab
# echo "none /data/virtual_machines/vbox/vbusbfs usbfs rw,devgid=$(awk -F : '/vboxusers/ {print $3}' /etc/group),devmode=664 0 0" >> /etc/fstab
# mount -a

I executed the above script (except didn't execute Line 5, and my user:group is vbox:vbox and not vboxuser.vboxusers, and the folder is at /home/vbox and not /data/virtual_machines/vbox), and the following was added to /etc/fstab. Please explain what Line 4 did and what the below line in my fstab file means.
Code:

none /home/vbox/vbusbfs usbfs rw,devgid=496
504,devmode=664 0 0

I then executed mount -a, and got the following response. The part about /var/www/main/ayb_resources and /var/www/main/ayb_cache does not exist is probably some old stuff which I can get rid of, but I am particularly interested in "mount point 0 does not exist" as it seems to be related to the above.

Code:

[root@devserver vbox]# mount -a
mount: special device /var/www/main/ayb_resources does not exist
mount: special device /var/www/main/ayb_cache does not exist
mount: mount point 0 does not exist
[root@devserver vbox]#

My total fstab file is as follows:

Code:

[root@devserver vbox]# cat /etc/fstab

Hi

I am using Centos 6.5 and i am testing Glusterfs.

I have at /etc/hosts :

Code:

123.456.789.000 host1
000.987.654.321 host2

And they can ping each other and all working great...

Glusterfs requires this command:

Code:

mount host1:/gluster-vmstore /home/nginx/public -t glusterfs

and if i run it manually it works great.

But when i restart checking using df -h is gone and is not working until i run it again manualy

I found on a tutorial that this edit on /etc/fstab will work after restart:

Code:

host1:/gluster-vmstore /home/nginx/public glusterfs defaults 0 0

But after restarting it was not working

Any ideas?

Thanks

Hi there guys,

I hope you can help me with a small issue that is kinda driving me crazy.
I'm running debian wheezy on a virtual machine and trying to mount some shares from the win8.1 host.
The lines I put in the /etc/fstab a
Code:

//192.168.0.10/dir1 /home/user/dir1 cifs credentials=/root/.secret.pwd,uid=1000,gid=1000,file_mode=0777,dir_mode=0777,iocharset=utf8,sec=ntlm 0 0
//192.160.0.10/dir2 /home/user/dir2 cifs credentials=/root/.secret.pwd,uid=1000,gid=1000,file_mode=0777,dir_mode=0777,iocharset=utf8,sec=ntlm 0 0
//192.160.0.10/dir3 /home/user/dir3 cifs credentials=/root/.secret.pwd,uid=1000,gid=1000,file_mode=0777,dir_mode=0777,iocharset=utf8,sec=ntlm 0 0

The first share gets mounted correctly, but not the other two.
This is the output I get when sudo-ing a mount -a:
Code:

mount error(115): Operation now in progress
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)
mount error(115): Operation now in progress
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

and this is what /var/log/syslog shows:
Code:

Mar 24 12:56:12 hostname kernel: [ 1887.029043] CIFS VFS: Error connecting to socket. Aborting operation
Mar 24 12:56:12 hostname kernel: [ 1887.030013] CIFS VFS: cifs_mount failed w/return code = -115
Mar 24 12:56:22 hostname kernel: [ 1897.052130] CIFS VFS: Error connecting to socket. Aborting operation
Mar 24 12:56:22 hostname kernel: [ 1897.053885] CIFS VFS: cifs_mount failed w/return code = -115

The same happens at boot time.

Now, the crazy thing is that if I run manually a:
Code:

sudo mount //192.168.0.10/dir2 /home/user/dir2 -t cifs -o credentials=/root/.secret.pwd,uid=1000,gid=1000

it works perfectly.

Now, I'm no power user, but I thought I'd be able to manage a couple of simple cifs shares...but then again I guess not
So, my questions so far a
1. how the heck do I make that work?
2. why is it not working? Might be the security? Should I choose perhaps ntlmv2? I read a bit around but I don't know this kind of security mechanisms, so...
3. why on earth is the first mount working just like a charm and not the other two?

You know what? I'm trying now to remove the sec option from the fstab, and see how that works out.

In the meantime, if anyone could lend a hand I'd appreciate it very much

am i right in saying that fstab only describes to the system what partitions should be mounted to what device (location) i know it can do a bit more than that...

but how do you get the system to mount file systems automatically at start up? is that a setting within fstab? under mount options...or is it a command that you need to type...or is it in another config file?

mount -t cifs //192.168.86.135/home/ /smbdata/ -o ussername=localhost.localdomain/smbuser,password=x
mount error 13 = Permission denied
Refer to the mount.cifs(8) manual page (e.g.man mount.cifs)


192.168.86.135 is my primary server IP and i tried to mount from another server which is accessible

Please help

I can't seem to mount a CD-R or DVD-R, doesn't matter if it is blank or not.
However, when I use a program such as Brasero, I am able to write to them. I cannot use dd to write to them.

This is the output of trying to mount/unmount.
Code:

root@delarocha-> mount /dev/sr0 /media/cd
mount: /dev/sr0 is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/sr0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail or so.

root@delarocha-> umount /dev/sr0
umount: /dev/sr0: not mounted
root@delarocha-> umount /media/cd
umount: /media/cd: not mounted
root@delarocha-> umount /media/cdrom
umount: /media/cdrom: not mounted

dmesg | tail
Code:

root@delarocha-> dmesg | tail

[ 1536.299915] EXT4-fs (sr0): unable to read superblock

I don't think it can be anything wrong with the disk, since it is a untouched disk.
Note: The results of everything(apart from dmesg I would assume), are the same for a CD-R and DVD-R

This is what I get while trying to dd a .iso and .mp4, respectively.

Code:

uname -a
Code:

When I used lsblk when I close the disk tray, it shows it mounted.
Code:

sr0                     11:0    1     2K  0 rom

But after I use the dd command to write the .iso, it disappears.

Here is my /etc/fstab
Code:

# /etc/fstab: static file system information.

I have also tried replacing /dev/sr0 in the above commands with /media/cdrom0.

Hi,

I have problems mounting my second drive at boot automatically.
(sorry i am a noob)

When i use the mount command, it works fine.
Code:

mount -t ext3 /dev/sdb2 /mnt/HD/HD_b2

But when i try to add one if the following lines to /etc/fstab
It will not mount the drive at boot or with Code:

mount -a

, also fstab is empty afer reboot (normal??)

Code:

/dev/sdb2 /mnt/HD/HD_b2 ext3 defaults,errors=remount-ro 0 1

Code:

UUID=553afede-fa45-4cdc-9972-c0a9aa899509 /mnt/HD/HD_b2 ext3 errors=remount-ro 0 1

Code:

/dev/sdb2 /mnt/HD/HD_b2 ext3 rw 0 0

Code:

/dev/sdb2 /mnt/HD/HD_b2 ext3 defaults 0 1

output blkid:

When mount command is used Code:

mount -t ext3 /dev/sdb2 /mnt/HD/HD_b2

The following line is added to mstab -->
Code:

/dev/sdb2 /mnt/HD/HD_b2 ext3 rw 0 0

I diont know what i am doing wrong, mount for HD_a2 works fine (other disk, worked at default), i hav e NAS DNS-325 where i installed Debian on. I used this tutorial to install debian.

The strange thing is, i had to reinstall my NAS, and befor it worked fine after i had installed debian 2 years ago, i just dont remeber how i fixed this.

Hi all. My first time post and very new to linux.
I am using linux Mint Debian version.

My goal is to auto mount 2 external harddrives (Each hard drive is 2TB) attached to the 2 usb ports on my asus wireless router model rt-n56r.

I have succeeded in auto mounting my first drive HDD1 by configuring fstab file:

//192.168.1.1/HDD1 /media/public cifs username=**,password=**,rw,nounix,iocharset=utf8,file_mode=0777,dir_mode=0777 0 0

At boot this partition is mounted without issue.

In attempting to mount the second hard drive HDD2 I added another entry in fstab as follows:

//192.168.1.1/HDD2 /media/public cifs username=**,password=**,rw,nounix,iocharset=utf8,file_mode=0777,dir_mode=0777 0 0

It appears that both HDD1 and HDD2 mount however, when entering the partition only files and directories of the second hard drive appear.

So I changed the mount point in the second hard drive to reflect /media1/public1 and after the configuration neither hard drive appears to have mounted.

I tried using UUID instead of path to partition but cannot get even 1 attached hard drive to mount.

I appreciate in advance the help and assistance to my query.

Hello all,

I was working through LFS 7.7 Chp 2.4 and mounted a wrong partition to /mnt/lfs.
I did the following commands while trying to mount the correct LFS partitions:
mount -v -t ext4 /dev/sda8 /mnt/lfs
mount -v -t ext4 /dev/sda9 /mnt/lfs/home
but I was supposed to mount sda11 and sda 12.

Now the system won't boot past the splash screen. I tried booting into a live usb and typed in the following commands
mount -v -t ext4 /dev/sda8 /
mount -v -t ext4 /dev/sda9 /home
but the system still won't boot past the splash screen.
Both gparted and the partition manager for the installer don't show a mount point.

How do I create a mount point from USB or is there another problem/solution?

Thanks

I've setup a NFS4 file share on an usb drive on a server at home for my personal use. Both client and server use Debian stable (3.2.0-4-amd64). I followed the tutorial he

http://initrd.org/wiki/NFS_Setup

My setup seems to work fine if I mount it manually, just won't mount at bootup. Looking around online I see that this has been a common and long-standing problem- evidently the system tries to mount the NFS before the network is up.

I found a work-around- add this line to the /etc/rc.local file:

Code:

mount -a -t nfs4

Now it works, but of course I still have to wait for the initial timeout (60 seconds?) and a few more for this to work.

I find this really odd. Lots of online discussion about this for many years going. What is the real story on this? Is there some configuration setting that I (and many others) have simply missed?

BTW- many of the solutions I see online are old, won't work with NFS4, or are OS specific.

thanks,
Keith Ostertag
