Debian :: Mounting Other Partition And Editing As Root?
Jan 22, 2011
I have Linux Mint (LMDE) on another partition and I guess I need to do some 'fixing' so I need to mount the partition. I can't, though, not by just clicking the partition (obviously?). I assume this is because I need root access to mount it.
how I can do this?:
1) CLI - mount via CLI by mounting at some point - for e.g., mine is /dev/sda3 so mount as ?
2) Use an 'editor' or file manager - such as Dolphin - how would I do this?
3) Use a Live CD/DVD - I think this way is unnecessary but it's a way, right?
Anything I missed? I guess gparted could mount it?
Which method would you use?
I think one could ssh into it but I'm not able to do that yet.
I need to exit the xorg.conf file which is recently really messed up.

I'm having some problems with a hosted openSUSE 11.2 server. It was running fine until I did a "zypper up" to apply patches. This included a kernel update.
On reboot the root partition does not mount the / partition giving the following error:
Unrecognized mount option "defaults.noatime", or missing value mount: wrong fs type, bad option, bad superblock on /dev/md2.
Through an Ubuntu rescue disk (this is what Hetzner provides) the disk can be mounted without problems.
( I installed a fresh openSUSE 11.2 with a similar configuration and got the same results after the update)
The server is a hosted installation from Hetzner in Germany with just the basics for LAMP setup.
The disk setup is as follows using software raid1:
swap /dev/md0 (/dev/sda1 /dev/sdb1)
/boot /dev/md1 (/dev/sda2 /dev/sdb2)
/ /dev/md2 (/dev/sda3 /dev/sdb3)

But any changes I make cannot be saved unless I'm in root. I might be doing this wrong, but I cannot log into root or figure out how to open this file as the root user. I'm still somewhat new to Linux, so could someone please give me an idiot-friendly step-by-step of what to do to open, edit, and save this file as a root user?

Just the last day or so, I've noticed a long pause when I boot my laptop, with lots of disk activity. dmesg says:
[Code]...
Why would there be a 15-second pause (during which the disk is slammed) between mounting root and mounting swap? During this time I see nothing but a blank purple screen, there are no cycling dots or text scroll. Is this normal and I'm just freaking out over nothing because there's no indicator of progress? GRUB default boot options: quiet splash nomodeset video=uvesafb:mode_option=1920x1200-24,mtrr=3,scroll=ywrap vt.handoff=7

I've installed debian squeezy recently and for some reason I have problems with mounting /home partition during startup.
There's an error:Mounting local filesystems...mount: special device /dev/mapper/isw_bbfedcffgi_Volume0p6 does not exist. failed
I've tried using fsck - no result the file system is healthy, I've tried formatting it once again (fresh copy, no user data) and it's not working. What is more mounting the partition manually goes well - I can read the data and write to it. All other partitions are ok.
I have no idea what's going on and why mounting /home fails. I've written this post on Polish debian users forum, but no response - only to give more info, so I'll put it here also:
ls -al /dev/mapper
crw------- 1 root root 10, 59 Nov 9 19:34 control
lrwxrwxrwx 1 root root 7 Nov 9 19:34 isw_bbfedcffgi_Volume0 -> ../dm-0
lrwxrwxrwx 1 root root 7 Nov 9 19:34 isw_bbfedcffgi_Volume01 -> ../dm-2
lrwxrwxrwx 1 root root 7 Nov 9 19:34 isw_bbfedcffgi_Volume05 -> ../dm-3
lrwxrwxrwx 1 root root 7 Nov 9 19:34 isw_bbfedcffgi_Volume06 -> ../dm-4

An old machine in our office, running Ubuntu 6.06 all of a sudden will not boot up. I get the following info during boot:
Uncompressing Linux... Ok Booting the kernel
mount: Mounting /root/sda1 /root failed: No such device
mount: Mounting /root/dev on /dev/.static/dev failed: No such file or directory
[code]....
I haven't changed anything on the system as far as I'm aware, and I ran some HD diagnostics and everything seems fine. however when I try to mount the drive with the following command:
sudo mount -t ext3 -o rw /dev/hda1 /mnt
I get the following error:
mount: wrong fs type, bad option, bad
superblock on /dev/sda1, missing code
page or helper program, or other error
In some cases useful info is found in
syslog - try dmesg | tail or so
I ran fdisk -l and it says the partition type is Linux. The output after running dmesg | tail :
[12207.483801] init_special_inode: bogus i_mode (101)
[12207.483809] EXT2-fs: corrupt root inode, run e2fsck
[12260.427078] init_special_inode: bogus i_mode (101)
[code]...
Update: After running e2fsck -p /dev/sda1, I get the following info:
/dev/sda1: clean, 142449 / 9584640 files, 5402711 / 19161520 blocks

Got problems with apt. So I discovered if I remove some stuff from root partition apt works normally again.
So I tested to copy 1GB file to root, but in the middle says disk is full, but there should be 1.8GB free if I type df -h.
Code:
Select alldf -h
Filesystem   Size Used Avail Use% Mounted on
rootfs     4.0G 2.2G 1.8G 56% /
tmpfs      10M 4.0K  10M  1% /dev
/dev/md0Â Â Â Â 4.0GÂ 2.2GÂ 1.8GÂ 56% /
tmpfs      492M   0 492M  0% /dev/shm

I'm booting to Kali 2.0 live from USB and wanted to add persistence, but I can't get OpenVAS setup. The setup script runs and eventually fails due to no more disk space. Here's my df -h output:
Here's gparted:
When the setup runs it fills up root (/) which is only 872mb. This is a 16gb USB so I'm wondering if there's a way to allocate some of the 11gb of unallocated space to root? I couldn't tell how to do this with gparted, would I need to build a custom Kali iso or something with different partitioning?

i use a 3rd party boot mgr.i installed jessie over etch on my old computer & only choice i saw for grub was sda & sdb where i wanted to install on sdb9.i tried installing it from my wheezy partition & it did but i ended up with 2 boots to wheezy.so i went back to etch.
my question is how to get grub on sdb9 like it was on etch.is there a trick or did i miss a prompt? on another note, that bug where the format hangs if you try & install over an old system is a little irritating. can't believe it hasn't been fixed.

I recently installed Lenny and used the "Guided - Use Entire Disk" option.I made separate partitions for root, /etc, /var, /home, /usr and swap.I trusted that the auto partitioner would choose sensible sizes but possibly that was a bad move, root is only 340Mb and is full.

The RAID level 1 interested me because of its redundancy in both drives. And I successfully made it in a couple of partitions. But, I always did it after Linux installation. Then, I create both partitions, use 'mdadm' to create raidtab and RAID device (md0, for example) and then I format the RAID device with 'mkfs' and mount it.
Until there, it's all OK.
But my problem is to mirror ALL the hard disk, inclusive root partition. To do that, I guess I need no Linux installation, then create the RAID (md0, raidtab, etc) and after that install Linux in RAID device created.
But I'm new in Linux world and I have no idea how to do that.
I use Debian Lenny, so I need a solution that uses only the first DVD of this distribution.

Is there a way where I can take like 50GB from my home folder (I have 375 avail., but using only 22GB) and put it to the root partition? Twice now my system has almost ran out of space on root, so luckly I was able to clear out old stuff so I don't have login issues after finding the hardway the first round lol. I just want to make sure I can login with out being forced back out because root don't have space to let me login.

I made a mistake in Gnome Disk utility tool. Instead of changing the options for a USB key, I changed the options of the root partition.
In Initial state, automatic options were desactivated. I just activated them. And after desactivacting them, I realized my mistake and switched back to "non automatic options".
By doing this, I suppose that defaults values were used since now, the system starts in command line mode and no more in graphic interface mode.
When I try the "startx" command, I get a "read-only" error.
With the command "sudo mount -o rw,remount /" the graphic interface is started.
Below is the configuration of the partition under the gnome disk utility tool :
"Mount at startup" is checked
"Show in user inteface" and "Require additional authorization to mount" are unchecked
Mount options : nosuid,nodev,nofail,x-gvfs-show
Mount point : /mnt/eb11d4d6-75db-XXXx-XXXx
Identify as : /dev/disk/by-uuid/eb11d4d6-75db-XXXx-XXXx
Filesystem type : auto
I do not want to change anything that could leat to a critical error. So what do you think I should do ?

If I selected:
For the root partition, I would like to use ext4, 10GB, but by default, the partition type 'extended' is suggested. Would there be any difference (advantages, inconveniences) if I selected the primary partition instead?

My root filesystems flooded so I'm trying to move it to another (bigger) partition but I'm not sure of the best method. I just tried to use "dd if=/dev/sda1 of=/dev/sda6" to copy it but all that did was give me a brand new partition with no freespace available presumably because the filesystem is smaller than the partition. Is it possible to make the filesystem bigger?

what if the root user by mistakenly stops/starts any service and tried to remove those traces from the log files and save those log files. Then how can we ensure that our log file is trusted. Is there any way where even the root(superuser) also cant edit/modify the contents of the /var/log/* files.

Ok. I have a media server running debian amd64. when I installed it I made separate partitions for root (/) home (/home) var (/var) and swap.
I'm adding some new hardware (mobo and ram) and want to reinstall debian. I would like to keep my home and var partitions intact and just reinstall everything in root (/) partition.
I'm unsure of how to do this during the installation. Do i need to format? how do I tell it to use the /var and /home partitions?

I'm using the IDE Netbeans (text editor) on my /home/michael Ubuntu account. I'm trying to open a file with Netbeans that's owned by root, I can't do this as I expected. So is there a way to run NetBeans as root, or is there a way to give netbeans permission to open/save files owned by root

I have come across the following statement: " When a FAT32 partition is mounted at '/media/windows', all access to '/media/windows' and everything below it is transparently handled by the Linux kernel using the 'vfat' module. Applications need not know they're dealing with anything else. However, mounting a partition at a location inside of another mounted partition is unpredictable, unstable, and generally a bad idea. "
Is it correct? Most of my partitions are mounted on /home, which is on a separate partition; and I have one "level 3" partition. I have been using Ubuntu for nearly three years so far with no problems (except for /home losing it's format once).

Being able to reset the root password by booting into single usermode by editing grub. This is a MAJOR flaw. I know it makes no real difference against internet bourne attacks, but even so I must say I found it shocking. The only way I've found to stop this is to encrypt the entire HDD, so noone could get into single user mode without first knowing the encryption key/password.

Sometimes Linux just make you want to throw the PC out of the window, and get a new one with WINDOWS on it...Having only just "got" the idea that there are a nunber of ways of issuing chmod, I now find that there is yet another when in the fstab file. It is an easygoogle to find out a workaround to make this drive RW, but doing that way one does not learn what is actually happening.how do I find out UID and GID? fmask and dmask, how do I find out what the current settings mean, and what they should be to allow RW access for various groups/users or for everyone?

I have finally been convinced to partition my 500GB hard drive from a two partition setup with root and swap to a three partition setup with root, swap, and home. I found a nice tutorial about how to do this, but here is my question:
A) How much space do I leave for the root partition and the home partition?

I initially installed SuSe11.2 with /tmp mounted on separate partition on another physical disk( there are two physical disks). Now I want to attach disk with existing SuSe11.2 to another motherboard so I would like that /tmp becomes part of the root partition. Will deleting /tmp mount point in /etc/fstab create automatically new /tmp from root at next startup, or something else has to be done to achieve, that in future, /tmp resides on root partition instead? In this way it would be much easier to move the disk with SuSe11.2 to another motherboard.
