Mounting A USB For Vbox

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:

Code:

/dev/sda1: UUID="e67e5c15-7b8b-9389-c311-e5d4c61326f9" TYPE="linux_raid_member"

/dev/sdb4: UUID="bf594be6-ffb6-469d-a3a8-246be66a4d90" TYPE="ext2"

/etc/mtab:

Code:

sysfs /mnt/HD/HD_a2/squeeze/sys sysfs rw,relatime 0 0
proc /mnt/HD/HD_a2/squeeze/proc proc rw,relatime 0 0

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 experts

I got an NFS mount that I want to make permanent. So I know I have to added it in etc/fstab. but all I have is the mount shown below:

Code:

mount test.com:/vol/myhome /home

correspondingly, I have googled a sample nfs mount entry for fstab and made this:

Code:

#in fstab
test.com:/vol/myhome    /home    nfs  rw,soft,intr    0       0

are they same? I mean like permission wise and everything?

Thanks

I am using phpVirtualBox, and everything is working perfectly. Then something changes, and I get the following error:
Code:

Could not connect to host (http://127.0.0.1:18083/)

I reboot the physical machine, or execute /etc/init.d/vboxweb-service restart, and then everything works for a while.

According to http://sourceforge.net/p/phpvirtualb...onnect-to-host, there are three reasons why this will happen.
Quote:
This indicates that phpVirtualBox could not connect to the vboxwebsrv server. Either the location setting in config.php is wrong, vboxwebsrv is not running on the VirtualBox host, or SELinux is blocking access to vboxwebsrv. If you have SELinux enabled
As shown below, it is not reason 2 or 3.

Code:

[root@devserver ~]# service vboxweb-service status
Checking for VBox Web Service ...running
[root@devserver ~]# service vboxdrv status
VirtualBox kernel modules (vboxdrv, vboxnetflt, vboxnetadp, vboxpci) are loaded.
[root@devserver ~]# service vboxautostart-service status
Usage: /etc/init.d/vboxautostart-service {start|stop}
[root@devserver ~]# service  vboxballoonctrl-service status
Checking for VBox watchdog service ...not running
[root@devserver ~]# sestatus
SELinux status:                 enabled
SELinuxfs mount:                /selinux
Current mode:                   permissive
Mode from config file:          permissive
Policy version:                 24
Policy from config file:        targeted
[root@devserver ~]#

Thus it must be that the location setting in config.php is wrong. config.php has the following default settings, and I left them as is.

Code:

/* SOAP URL of vboxwebsrv (not phpVirtualBox's URL) */
var $location = 'http://127.0.0.1:18083/';
...
// Host / ip to use for console connections
#var $consoleHost = '192.168.1.40';

According to http://sourceforge.net/p/phpvirtualb...-configuration, "If VirtualBox and phpVirtualBox are on the same physical host, you may leave the $location setting alone". VirtualBox and phpVirtualBox are definitely on the same physical machine.

Please provide recommendations.

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:

web@delarocha-> dd if=/dev/sr0 of=~/Downloads/xubuntu-14.04.1-desktop-amd64.iso
0+0 records in
0+0 records out
0 bytes (0 B) copied, 0.000377316 s, 0.0 kB/s

0+0 records in
0+0 records out
0 bytes (0 B) copied, 0.000377179 s, 0.0 kB/s

uname -a
Code:

Linux delarocha 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt2-1 (2014-12-08) x86_64 GNU/Linux

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.
#
# 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

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

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

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?

My real objective is to clean existing nodes from a Hadoop cluster, claim the space etc. and do a fresh installation of another distro.

Below is the space descr. of one of the master(namenode):

Code:

During the new installation, I have run into space issues for all the nodes/hosts

Code:

Not enough disk space on host (l1032lab.se.com). A minimum of 1GB is required for "/usr" mount. A minimum of 2GB is required for "/" mount.
Not enough disk space on host (l1033lab.se.com). A minimum of 1GB is required for "/usr" mount. A minimum of 2GB is required for "/" mount.
Not enough disk space on host (l1034lab.se.com). A minimum of 1GB is required for "/usr" mount. A minimum of 2GB is required for "/" mount.
Not enough disk space on host (l1035lab.se.com). A minimum of 1GB is required for "/usr" mount. A minimum of 2GB is required for "/" mount.

Now the installation requires a lot of space under /, /usr, /var and /home mounts which on both master and the slaves is less but there is lots of space in master under these two disks:

Code:

/dev/mapper/vg00-FSImage
                      917G  200M  870G   1% /opt/hadoop-FSImage
/dev/mapper/vg00-Zookeeper
                      917G  6.5G  864G   1% /opt/hadoop-Zookeeper

and on slaves under these 8 disks.

Code:

/dev/mapper/vg00-00   559G   33M  559G   1% /opt/hadoop-00
/dev/mapper/vg00-01   559G   33M  559G   1% /opt/hadoop-01
/dev/mapper/vg00-02   559G   33M  559G   1% /opt/hadoop-02
/dev/mapper/vg00-03   559G   33M  559G   1% /opt/hadoop-03
/dev/mapper/vg00-04   559G   33M  559G   1% /opt/hadoop-04
/dev/mapper/vg00-05   559G   33M  559G   1% /opt/hadoop-05
/dev/mapper/vg00-06   559G   33M  559G   1% /opt/hadoop-06
/dev/mapper/vg00-07   559G   33M  559G   1% /opt/hadoop-07

I'm a bit confused as how to proceed - I was wondering if I can partition one or more of these disks and allocate those under /, /usr etc. and proceed with the installation but then will these disk partitioning and mounting/un-mounting corrupt the existing /, /usr etc. mounts ?

For whatever reason, when I try to mount a data DVD I get the following message:

Unable to mount [disk name]
Error mounting: mount exited with exit code 1: helper failed with:
mount: mount point /media/cdrom does not exist

Yet, if I put a DVD video in I can play on any of my video apps, yet I also can't mount those in a file browser. I have no idea what has caused this. I haven't backed up data to disks in a long time, I only did so today because I'm running low on space in one of my drives.

I was told elsewhere that I needed to alter a file: /etc/udev/rules.d/70-persistent-cd.rules

But I have no idea how to do this, and what I found there does not look like what was shown. This is what my file looks like:

Code:

# This file maintains persistent names for CD/DVD reader and writer devices.
# See udev(7) for syntax.
#
# Entries are automatically added by the 75-cd-aliases-generator.rules

Any suggestions would be appreciated.

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 have two raspberrys, one running OSMC and another running raspbian. The first one has two 1TB hard drives plugged in through a powered usb hub. I want to access to the osmc hard drives from the one running raspbian. They are both in the same local network, the osmc one has the ip 192.168.1.24 and the raspbian one has 192.168.1.28. Both are static ips.

These are the hard drives::
Code:

osmc@osmc:~$ ls /media/ -la
total 36
drwxr-xr-x  4 root root  4096 Mar 31 18:28 .
drwxr-xr-x 23 root root  4096 Mar 15 13:35 ..
drwx------  1 osmc osmc  8192 Mar 30 21:54 ELEMENTS
-rw-r--r--  1 root root   232 Mar  6 13:34 README
drwx------  1 osmc osmc 16384 Mar 30 15:22 TOURO

ELEMENTS and TOURO, two ntfs hard drives that work just fine.

I tried sharing the first one through nfs with the following config (i copied the parameters from a tutorial):
Code:

osmc@osmc:~$ cat /etc/exports
# /etc/exports: the access control list for filesystems which may be exported
#               to NFS clients.  See exports(5).
#
# Example for NFSv2 and NFSv3:
# /srv/homes       hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check)
#
# Example for NFSv4:
# /srv/nfs4        gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check)
# /srv/nfs4/homes  gss/krb5i(rw,sync,no_subtree_check)
#
/media/ELEMENTS/Pelis/ 192.168.1.0/24(rw,subtree_check,insecure,no_root_squash)
/media/TOURO/Series/ 192.168.1.0/24(rw,subtree_check,insecure,no_root_squash)

and from the pi running raspbian I have confirmed that I can see the drives being shared:
Code:

 /media $ showmount -e 192.168.1.24
Export list for 192.168.1.24:
/media/TOURO/Series/   192.168.1.0/24
/media/ELEMENTS/Pelis/ 192.168.1.0/24

Now, when I try to mount them, all works fine, but when I ls the folders nothing cames back. This is my fstab:
Code:

1cat /etc/fstab
proc            /proc           proc    defaults          0       0

Code:

apoc@raspbian ~ $ ls /media/pelis/
apoc@raspbian ~ $

The superweird thing is that they are mounted, as they show up if I run "df -h"

drwx------  1 apoc pi    28672 mar 29 16:09 series

Note that the group for the two folders is "pi", but if I umount the drives it becomes "apoc" (my nick and my personal group).
Code:

ls /media/ -la

drwxr-xr-x  5 root root 4096 abr  2 18:36 .
drwxr-xr-x 22 root root 4096 mar 25 16:14 ..

drwxr-xr-x  2 apoc apoc 4096 abr  2 18:36 pelis
drwxr-xr-x  2 apoc apoc 4096 abr  2 18:36 series

Both users ("osmc" in the osmc pi and "apoc" in the raspbian one) have the same uid: 1000.

What am i doing wrong?
