Server :: Shrink Disk Partition After Reducing LVM?
Jan 19, 2011
I run Fedora FC13-x64. Recently I added a few TB's of RAID5 storage tto my server and moved most data from the root filesystem to that. Now my root volume is way too big. My basic install resulted in a 1TB LVM volume group entirely dedicated to a single lv_root.
Now I want to make room and eventually clone this disk to a much smaller root disk. I see many threads about reducing the size of an LVM logical volume. My first steps were succesful. I used lvreduce and resize2fs to reduce the size of the logical volume and filesystem. I also user pvreduce to reduce the size of the physical volume group.
But still gparted and fdisk report the physicalk volume (/dev/sde2) as 900GB. The embedded LVM stuff is as small as 60GB. Anyway LVM manager and GParted doe not allow me to shrink /dev/sdf2 to snuggly fit the LVM stuff in it.

I need to install Fedora on 4GB SDHC card, so the space is limited.My question is what files (documents, manuals, temporary files, logs, unused packages etc) I can remove, without harming the system?So far I cleaned /tmp, /var/log, trash what else?

GParted, and the Win7 partition editor before installing won't let me shrink it. Parted Magic was no help, wouldn't even work.

Just installed Fedora 13. And just as i finished installing, recovering backup and configuring everything. I realized that i forgot to make an extra partition (for experimenting with other distros).
During the Fedora installation i chose to include all three hard drives in the file system. So now sda, sdb and sdc are all included in the lvm group.
Found this thread in the forum: [URL]
Can i follow these steps to shrink the partition on sdc without damaging my current fedora installation? Can i run the commands straight from the shell, or do i need to boot up from a livecd?

Currently I have a four partition setup: One ext4 /boot partition for Fedora, one LVM partition, one ext4 partition (which has Ubuntu), and one swap partition. What I would like to do is shrink down the ext4 partition which has Ubuntu on it and increase the size of my LVM parition (and increase the Volume Group, filesystem, etc. within the LVM). However, I've been searching on Google and the only solutions I find is to make the free/unpartitioned space and then create a new LVM partition and stretch the VG over the two LVM partitions. However, I already have 4 partitions, so I can't make the fifth one.
Is there any possible way I can increase the size of the underlying LVM partition itself?

Having using full-time on Windows (as a "trip down memory lane") I decided that Ubuntu is way better. Now, it won't resize my full-drive NTFS partition. I can move it on the drive, but I can not resize it.

know the best way to shrink the Windows 7 64 bit primary partition (C: drive)? The C: drive was originally just over 900 GB free space. I shrunk it using Windows 7 Disk Management, but it would only let me shrink to 468 GB, which I did. I want to shrink it to 100 GB. Will G-Parted work for this? Will I be able to boot into Windows after I use G-Parted? Or will I have to use the Repair Disc to fix Windows? If so, will the Repair Disc work. I have a new PC. I had Ubuntu 10.10 dual booted with Windows XP on my old PC.

How can I shrink a partition to the filesystem size?I copied my ubuntu installation via dd from a smaller partition to a little bit bigger one to have all the same settings and programs and upgraded the distribution afterwards. Now the filesystem is smaller than the partition size. It would be nice to have both partitions have the same size so I could copy back the newer distribution someday ...GParted recognizes the new partition as 27 GB, the filesystem is just 25 GB.Is there a nice way to resize the partition to exact the size of the filesystem so that the filesystems remains untouched and no data might me lost?

this might deviate from "installation" theme.. I'm writing an immediate problem since the last thread: [URL] problem is the vista partition is impossible to shrink now, though there's 50 G free space. Every try found in : [URL] does not work including Perfect disk degrag. I think this is because fedora system is there. some code is written to vista partition..that vista cannot handle.....

After four attempts and diverse partition map problems, I finally managed to install successfully clean versions of both Mac OS X Snow Leopard and Ubuntu Lucid Lynx on my old MacBook Pro C2D (2,1) and a new 320 GB HDD, by following these instructions:[URL]
Now, I've got a big partition for Mac OS X (286 GB) and a small partition for Ubuntu (30 GB, as well as two smaller partitions for grub and swap). However, I'd like to shrink the Mac OS X partition to, say, 35 GB, and use the freed up 251 GB as a shared partition to keep files for access from both OSs. But Mac OS X Disk Utility won't let me resize the Mac OS X partition (and warns that it might not be a smart thing to do, as the disk has been partitioned for Boot Camp, etc).
Is there some way I can resize the partition, or do I have to start all over again?

I've been trying to use GParted Live CD to shrink my Windows XP partition and allocate this space to /home.
On GParted I shrank my /dev/sda1 (Windows) from 36GB to 26 GB. Then I had 10 GB of unallocated space. I didn't know how I could use this unallocated space to increase the size of /dev/sda7 (/home). How do you do this?

I recently installed ubuntu alongside windows 7 on my machine. I ardly know anything about partitions, but I managed to shrink the windows partition to make space, abd then use the ubuntu installer to create the ubuntu partition. But I hadn't realized that there were actually 3 Windows partitions - "Acer C:", "Recovery", and "System, Active, Primary Partition".
So I didn't know that I should have made the ubuntu partition "Extended", which means that I can't make new partitions anymore. Is there anything I can do without reinstalling ubuntu?

Alternate Heading: Unable to use opensuse partitioner to fully format a Seagate 1Tb drive OK. Swapped over a motherboard to increase the number of slots available for hard drives so that I could expand my raid array (4 X 1Tb drives). Discovered I had no thermal paste so all delayed for 24 hours while I bought some, miscalculated on rebuild and had to reinstall OpenSuse but in the end system is now up and running. Unfortunately when I formatted my new 1Tb drive (Seagate) it formats to 931.50 Gb while the other 4 drives formatted to 931.51 Gb (they are WD). I'm now in the position that when I try to add this new drive I get :
mdadm: /dev/sdc1 not large enough to join array
Is there any way I can resize the existing devices down to 931.50 Gb so that I can add in the new drive without having to restore the array?

I have just over 20GB of empty space on C:. When I click it under disk-management, the window comes up and says I can only resize it 192 MB less than what it is. But I have 20GB free. Any ideas on what is wrong? I also have this odd 9.56GB partition that is empty. DM says it's "EISA configuration"...whatever that is. I am planning to allocate about 10GB for F11 if this pans out ok.

To install Ubuntu alongside Windows 7, I have to shrink Windows 7 partition C:. But due to some unmovable files, I cannot shrink as much as I plan by using Windows own shrinking tool. I guess many of you who have both OSes on the same hard drive must have similar experience.

I want to configure Name Server i.e., DNS to my red hat linux box in a production enviromnt.The ram is 2 GB and Hard Disk size is 200 GB. How much space should I give /var, /usr, /boot, /root and home partition. May be I am wrong in partition point of view while installing fresh red hat but to install for home purpose and server end is different. So kindly guide me the hard disk partition size to ready it for name server.

I have a hard drive where one partition is used as part of a logical volume (LV) using LVM. The partition table is corrupted and prevents the partitions from showing as devices in /dev/. The corruption prevents the logical volume from coming on-line b/c LVM cannot find the part on the corrupted disk. I (am pretty sure) I know the block offsets and lengths for each partition on the disk but do not want to write to the disk in case I am wrong.
How do I go about recovering the logical volume in this scenario?

Is there any way to make a disk image of an active partition? I have to get a complete backup (partitions, MBR, all data files) of my server without bringing it down to do it. I want to have a backup that, in the event of a system failure of any sort, I can quickly restore onto a new, bare hard disk and have the system back up and running. The windows equivalent of this would be something like Drive Image XML, this is the functionality I am looking for.

I have a 2 TB disk in an external SATA dock, formatted with a single ext3 (Linux) partition, which doesn't show up in the Windows 7 Computer Management->Disk Management utility, even as a raw/blank disk. I've verified that there's nothing wrong with the disk by connecting it to my Linux machine and mounting it, and I've verified that the dock is functioning properly by connecting a different FAT32-formatted disk, which mounts flawlessly as expected.I realize that I can't actually read the ext3 partition without additional software (e.g., Ext3IFS), but why doesn't the disk show up at all? Is there some sort of stupid anti-Linux filter built in? Is there any way to force Windows to recognize the disk, so that I can at the very least use direct block access with it?
Background: I want to clone an identical 2 TB disk onto this one. Due to my hardware layout, it's much easier to have the source disk attached to one machine and the destination disk connected to another, and do the clone over the network (the network is not a bottleneck with switched gigabit ethernet), than it is to hook them both up to one machine.(1) I did this once before when both machines were running Linux, but I've since upgraded the destination machine and decided to switch back to Windows for regular desktop use. I've got Cygwin installed, and have verified that the same basic method (dd + nc) will work, but I can't do anything if Windows doesn't even consider the destination disk to exist.I only have one eSATA port on each machine. Opening them up just to do this clone is a rather large annoyance. Also, since this is my backup disk, I'd like to eventually automate the cloning from the active disk to another one that I regularly swap with a third disk that I store off-site.
