CentOS 5 :: How To Resize LVM Partition
Feb 25, 2011
I have a default centos 5.x install on an 8GB hard disk. (This means the volumegroup is mounted to / ). I've increased the size of that hard disk to 12GB. (so yes, fdisk says my disk is 12GB)
I now need to increase the LVM to use the 12GB instead of the 8GB. Every single article I've come across says:
"run lvextend on your vg you want to increase, then unmount, reboot, run live cd or whatever and then run resize2fs".
But of course lvextend +anyG returns an error saying not enough free extents
lvextend +100%FREE returns saying the extents matches extents
How can every the google result be wrong? How can I simply tell this LVM that it's now a few gb larger?

I have around 30gb of free space in my partition table immediately before the Linux partition. I want to resize my linux partition to take up this space.
I tried booting with live cd, sucessfully umounted the hard drive but found I could not resize the partition. On clicking the 'edit size' button, partition manager recognised the free space before the partition but when i reduced this, the 'ok' button was greyed out. (it was not greyed out for the windows partition so I could, in theory, increase the windows partition to take up the free space but this is not what i wanted to do).
I am pretty sure that I had managed to unmount the drive correctly as the padlock symbol had dissapeared (I took the attached screenshot, which does show the lock symbol, after rebooting into my normal system).
Anyone got any ideas as to why it wont allow this? There is no reason why i can resize the partition to take up the free space BEFORE it is there?

I installed Fedora 13, but did not expect it would set up a LVM on the entire remaining unpartitioned space.
So I'm now trying to resize the partition the LVM is on. I already resized lv_home using system-config-lvm... however now lv_swap resides at the end of the physical volume. If I assume correctly that this also means that it resides at the end of the sda6 partition, I need to move it in order to resize the partition.
It now looks like this: [URL]
How would I go about moving lv_swap right next to lv_home? And how can I actually resize the partition? gparted doesn't seem to be able to resize lvm2 partitions.

Ubuntu 10.04 64-bit (installed on installer)
What will be an easy and safe way to resize partition? Boot up the LiveCD? Or can I run resize2fs on Ubuntu while the latter is running?
Code:
This is a newly installed box without files on /kvm. Now I want to resize /home taking up the complete capacity of /kvm which will be removed/deleted.

I'm running Fedora Core 14 on my server and in copying over all the stuff I had backed up before the install, i recived the message that one of my volumes was nearly out of space. Since this is just a partition on my hard drive, I could resize it to make it larger, but I don't know how. It's a ext4 partition on my 2nd hard drive.

On recomendation from the team installing the DB on our new server, all the partitions etc on our VM were created as LVM's. The setup for this is like this:
Disk 1
-> /boot
-> /swap
-> LVMpartition1
[Code]....

I need to resize (increase) LUKS partition. I have found a lot of manuals, but they are just for LVM volumes(I dont use LVM and I dont plan to use it). I have HDD splited to the 4 parts:
sda1(/)
sda2(LUKS)
unalocated
swap
I want to increase LUKS partition, by using the part of unalocated space.
BUT I dont want to do the following:
Backup data from LUKS partition
Delete LUKS partition
Create new bigger LUKS partition
Restore data to the LUKS partition

I've been upgrading a Fedora server over the years. Once it was Fedora Core 2 now it is Fedora 10. Now I want to continue the upgrade process and upgrade the server to Fedora 11. The problem is that the boot partition is 100MB but Fedora 11 wants a 200MB boot partition. Looking at Fedora 13 it seems a boot partition of 500MB is gonna be the norm. I would just resize the boot partition but there is a LVM directly after it taking up the rest of the drive.
How do I resize my boot partition in this scenario?
My current line of thought is to use G4L to backup both partitions, then restore the boot partition to a large drive, increase the size with parted then restore the LVM backup after it.
So far G4L has been reluctant to backup the boot partition of Fedora on a test rig to an NTFS drive. Not sure if I should be backing up the image to a ext3 drive.

I want to install linux next to my Windows 7 Ultimate x64 and changed my windows partition from 700GB to 100GB. Now I want to use the other 600GB for linux and formatted it in Paragon Partition manager.
But when I try to install OS 11.4 I get the message that it can't resize the partition because of the type (which is NTFS) and it wants to delete the whole disc including the windows partition. How do I fix this? Do I need to delete the 600GB partition again in Paragon so its unallocated and then use Suse on it?
Or can I better first install Linux and then Windows? (for next time so it would be nice if the above worked out)

I have read several tutorials on how to install it on my Laptop with pre-existing XP without destroying XP in order to get a dual-boot system. For example on those two pages...
[URL]
and
[URL]
...it reads that in the Ubuntu install menu I have to select "manually edit partition table", which I have found and selected, and then I should supposedly be able to edit the size of the desired partition. However, no option for changing the partition size appears. Instead I get a menu where I am asked to determine how I want to mount the partition (as ext4, ext3, etc.) and if I want to format it. However nowhere it mentions anything related to "change size" or similar.

I made three partitions when I installed Ubuntu. Ubuntu 20.1 gig. windows 20.1 gig. data 110 gig
I no longer want or need the windows partition. so I used system > administrator> disk utility to delete the windows partition. Now to hopefully prevent a problem. How do I enlarge the Ubuntu partition without causing problems?
Can I do it while I am ubuntu or do I need to do it from the live cd or what?

I am trying to resize a Windows XP partition. The partition has plenty of space available. When I boot off the CD, I open Gparted. I try to move the partition down, but it does not move at all.
Within this Windows installation, it only shows 1% fragmentation.
I want to dual boot using two partitions.

I have a laptop with a 320GB disk. Windows 7 and Ubuntu 10.04 It has 8 partitions: [From Testdisk]
[code]....
Long story short, after reinstalling windows 7 and messing around a little with its partition and the other ntfs one (resizing etc); Gparted won't open the disk. It shows all the disk as unallocated space, And throws a message to the terminal which says something like "Can't have a partition out of the disk." Funny thing is that *almost* everything is working fine. Everything works except that ubuntu can't use the swap. (Dmesg says: "Swap area shorter than signature indicates") Also, testdisk, if i run a deep search for partitions, finds the last partition twice, but the second time the partition goes from 37129 0 1 to 40240 254 63 , while the disk ends at 38913 255 63. The problem is that I can't use Gparted now and I want to resize a partition.Also I believe that going without swap is not good for ubuntu.

I am dual booting Windows 7 and Ubuntu on my laptop, and I'm trying to resize my ubuntu partition to make it larger. When I boot from the GParted Live disc , however, It only recognizes the existence of my 160 Gig windows NTFS partition which has ~15 Gigs of free space, which I want to reformat and expand ubuntu into (I freed that space by shrinking my windows partition from inside windows 7). I know my Ubuntu partitions are there (I'm in Ubuntu now, plus my HD is 200 Gigs not 160), but I can't see them.
I have a feeling this has something to do with my resizing of my windows partition from windows, but I'm not sure.
more info:
Code:
sudo fdisk -lu
Disk /dev/sda: 160.0 GB, 160041885696 bytes
240 heads, 63 sectors/track, 20673 cylinders, total 312581808 sectors
Units = sectors of 1 * 512 = 512 bytes

I'm dual booting Win7 and Maverick and I'm running low on diskspace on my Ubuntu partition.I booted into an Ubuntu 10.10 live CD and opened Gparted. After shrinking the storagepartition I wanted to grow the extended ubuntu partition into the unallocated space to the left, but for some reason it won't let me do that.

How do I resize an ext4 partition including moving the start address? Actually what I want to do is extend the partition in front of it but that means first making space between partitions 1 and 2.As best I can tell resize2fs will resize the partition but not let me move the start addres. And fdisk will run, on say /dev/sda3 (the one I want to resize), but its default display doesn't show a start and end address which leads me to believe that fdisk isn't going to do what I want either.

I am trying to install Debian for my best friend by resizing his Windows partition so that I can install Debian on a separate partition. But, I get this message when I try to resize Windows: "for some unknown reason impossible to resize this partition. Check /var/log/syslog or see virtual console 4 for details." I do not know how to check virtual console 4 for details and besides I won't be able to interpret it. I also tried defraging the Windows hard drive several times and using several livecds with GParted to try to resize. They all failed.

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.

I would like to resize the /home partition but it is mounted and when umount is run, it errors with 'busy'.
System Configuration:
I installed jessie on a laptop with one SSD. I used guided partitioning and selected the whole drive with multiple partitions. The /home now takes up 420 GB. I would like to reduce that to 20 GB to make room for another partition.
What are the methods reduce this partition?

I have Vista and F11 dual booted on my system. I wan't to resize Fedora(I think Vista has already been shrunk as far as It can) and install Debian as a third OS. Fedora takes up all the free space and I am only using a small amount of the partition. I am not sure of the best way to do this. Can I boot the Debian live cd and resize Fedora at the partion step? Or do I need to boot a live F11 cd, repartition and then boot the debian cd? Or is there a better way?

I threw F12 KDE on my spare rig and wanted to throw Ubuntu on it as dual boot so I can play around with different things in each flavor. I installed F12 across the entire drive and later decided I wanted to try Ubuntu with it dual boot. I booted to Ubuntu's LiveCD and fired up GParted - but GParted can't resize the partition. It just gives me a 200mb EXT4 partition and "lvm2".

The openSUSE 11.2 installation disk doesn't want to let me resize my NTFS-based WinXP partition; it just says that the fs is inconsistent and that I should check this issue in windows... But even though I've scheduled diskcheck to run after a reboot, it doesn't! Is there some way of "forcing" the diskcheck to run upon startup, or how else can I resolve this issue (without re-installing my entire system)?
