Anyway To Re-size Root Partition Without Using Live CD ?

Hi Forks,

I have centOS installed on VM & cpanel is installed,
Now i can see that /usr partition got full.

i.e. Output of df -h
root@linux [/]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/hda2 18G 661M 16G 4% /
/dev/hda8 59G 4.3G 52G 8% /home
/dev/hda7 996M 431M 514M 46% /tmp
/dev/hda5 7.8G 7.2G 220M 98% /usr <-- FULL
/dev/hda3 7.8G 1.5G 5.9G 21% /var
/dev/hda1 190M 21M 160M 12% /boot
tmpfs 1005M 0 1005M 0% /dev/shm

But if i check under /usr it's shows only 4.9G,

root@linux [/]# du -sch /usr/
4.8G /usr/
4.8G total

wheres other size utilized?, Please let me know if any other detail is require.

Thanks

Hi All;
Can someone give me some guidance on partitioning a 4TB drive into one partition ?

My goal is to align the partition for best performance. I searched the net for advice and I've found a lot of information on it but am still confused.

After setting the label to gpt,

I tried mkpart primary 0% 100%
and I get the warning that the partition isn't aligned

then I tried mkpart primary 1 -1 (which I really hoped would get me completed)

and when I do an align-check on partition 1, it reports 1 aligned

but then when I do an fdisk -l,
I get the warning that partition 1 does not start on a physical sector boundary

I read that sector size is usually 512 bytes but on some (or perhaps all) larger disks, the sector size is 4096.

I am really not knowledgable in this area and not sure if the above message about partition 1 not starting on a physical sector boundary is important or what impact this will have to my performance. Since these 4tb drives are being used in a media server, I'd like them to be as fast and efficient as possible.

Can you offer some guidance or perhaps some commands on how to partition my (full) 4tb drive into one partition so it is aligned and also so the partition table starts on a physical sector boundary ?

Also, is there a Ubuntu utility to display the sector size of a disk?

I have been researching this issue off and on for a few weeks and would like to finally get this partitioning completed this weekend so I can get on with setting up my system.

Thanks.

Hello all,

I am new to linux but not new to PC's.

I am self taught in everything i know so far.

I have an issue i am looking for some guidance on, i have burned an ISO copy of AVLinux & booted from the Live DVD.

chose to install on partition & created all the necessary file systems etc with GParted then proceeded with the install.

Completed install but when i try to boot no joy.

I have EasyBCD installed on Vista to manage to boot processes.

I am able to get to Grub4dos window & grub> prompt.

I have tried many commands of which i have identifeid the partition is there as correct filesystem, when running the /vmlin....TAB command it locates the name of the linux distro, if i set the drive partition to makeactive it boots up saying no operating system them have to change it back to Vista.

I have two pics that show the grub configuration reading from the live DVD, the install appears to have some missing or not right as opposed to the DVD, can anyone assisst how i can fix this issue?

Do i have to copy each file over manually from the Live DVD's folders?

Cant attach images here so here is the differeneces,

these are the listing on the Grub configuartion being read using the Live DVD,

1. /etc/grub.d
2. /boot/grub/device.map
3. grub-install
4. grub-mkconfig
5. grub-mkdevicemap--device
6. grub-mkfont
7. /boot/grub
8. /boot/grub/grub.cfg
9. /etc/default/grub

Here is what way they are on Live DVD,

1. Present
2. Present
3. Present
4. Present
5. Present
6. Present
7. Present
8. Yellow information bubble
9. Present

My install on partition,

1. Present
2. Yellow information bubble
3. Red X bubble
4. Red X bubble
5. Yellow information bubble
6. Present
7. Yellow information bubble
8. Yellow information bubble
9. Present

what do i need to do to remedy this?

i have attempted the install on couple of different drives, no success.

Hi all,

As you can probably tell I am new to Linux and new to the forum, I am using Kali and Mint both as live Linux environments on USB drives, all is good and I am finding my way around, the reason for the post is that I need to copy 15 CF cards that have multiple partitions, Windows isn't really an option as it can only see one partition on a removable drive, so here goes with Linux.

The CF cards contain Windows Embedded XP in one partition and a separate partition for user data which isn't protected, not that the contents matter, only the fact that it is bootable with multiple partitions, the object is to upgrade the old 2gb cards to 4gb cards to add an additional program on the embedded drive, but they are both full.

as long as I can copy both partitions over the partition size doesn't matter as I can resize that if necessary, but I need both partitions to copy over to the new drive.

I have read that dd command is the way to go but cant find much on multiple partitions which display in Linux as two drives, so how do I go about this, any pointers

Ideally I would like to automate the process as this is something that we could end up doing on a regular basis, I have seen a USB drive that was plugged into a PC and through a basic GUI allowed you to copy a HDD but I don't know If that would do both partitions, something for the future?

tried installing linux mint on a partition that i created. it keeps saying no root file system is defined, please correct from partition menu. any help would be great. cheers

I recently bought a WD external hard drive for storing file of several types. Using gparted I made two partitions, one ntfs for windows files and an ext 4 for linux files. Strangely, I have complete access to ntfs partition from linux side of duel boot system, but do not have permission to access ext4 partition. My root password does not work when I use su to gain root access. It works fine on built in hard drive.

Hi folks,

as my title says, i need to protect an ext3 partition in my external 500GB toshiba usb hard diks. it is a 250gb Partition. so if i try to open the partition on any linux or windows system (using a utility), it should ask for a password to open the partition. pls advise.

Dear Linux magicians

When I tried to partition my hard drive for installing Debian Wheezy, I get the error:

For unknown reason it is not possible to change the size of my partition. Check /var/log/syslog or look at he fourth virtual console (VT4)

Obviously I have no idea what this all means, clearly I'am a beginner. Excuse me for my bad English, I'm not a native or regular speaker. I have to install Debian for school...

Kind regards

OK Im pretty new to Linux and learning so much, but with RHEL6,

When your taking a test and they say to make a partition this size/name it this, how do you know which disk to partition if you do a listing?

I get so confused with the fdisk stuff and I would really love it if someone is kind enough to help me out.

UPDATED:
I installed a Deb 7 Srv w LVM w following partitions:
The end product should become a mail server (Citadel) and in time also a Web server.

Now i want to _shrink_ the HOME partition so I can expand my VAR partition. Looked for guides but haven't found any site useful so far

I tried to find a way to do it when I installed it but it didn't seem to offer me this at this time even I looked around for a while.

How do I do this shrinking of HOME and extending of VAR partition??
please be fairly specific as Im not a pro yet
