How do I mount a partition that is in an image file? I have a file called centos.img that has 3 partitions in the file. I need to copy data to the third partition on that image file. I have seen things about a loop back device (which is fine) but then it talked about an offset parameter and I dont know what that is or more importantly what number to use. I hope I'm on the right track. How

I tried it on loop. 1. mount /dev/loop0 /mnt/test -t ext3 2. cp files to 100% full 3. umount /mnt/test 4. fsck.ext3 -f /dev/loop0 Inode xxxxx, i_blocks is xxx, should be yyy. Fix?

Hi, I enabled dir_index on a filesystem and dumpe2fs -h also reports this. My understanding is that this will be used for newly created directories and that old directories can be indexed using "fsck.ext2 -D". Two questions: - Is there a way to tell is a given directory is indexed or not? - Is there a better way to index the root fs than to boot off a live CD? Best, Norbert

Hi: I have an NFS volume that I'm trying to resize a partition on. Something about the fdisk process is corrupting something on the drive Before running fdisk, I can mount the volume find: $ mount /dev/sdo1 /home ... and the volume is mounted fine. And, $ e2fsck -f /dev/sdo1 /dev/sdo1: clean, ... But then I run fdisk to rewrite the partition table of this drive, to expand the /dev/sdo1

Hi! I recently tried to mount a filesystem in RAID1 mode using loopback devices. I followed the instructions at [1]. Here''s exactly what I''ve done: $ dd if=/dev/zero of=raid1_0.img bs=1M count=500 $ dd if=/dev/zero of=raid1_1.img bs=1M count=500 $ mkfs.btrfs -m raid1 -d raid1 raid1_0.img raid1_1.img $ losetup /dev/loop0 raid1_0.img $ losetup /dev/loop1 raid1_1.img $ mount -t

Hi all, I want to setup a linux workstation with FC4 and with all the partitions (except for /boot) under LVM to be able to resize them in future. I don't need online resizing, I can shutdown the system and reboot with the rescuecd when needed. I have done some test on this configuration and I have sverals doubts: If i format a partition with the resize_inode feature enabled and I resize it

Hi guys, I have Xen 3.0.3 installed with yum on Centos 5.1. I''am facing an issue trying to resize the disk image of a centos 4.5 VM. The VM disk size is 50Go and i need to add 150Go. I tried two methods so far : -------------1st method----------------------- dd if=/dev/zero of=<image file> bs=1M conv=notrunc count=1 seek=2500 * losetup /dev/loop0 <image file> * e2fsck -f

Hey, guys. I have a problem when installing syslinux 4.06, and I'd be grateful if someone could tell me how to solve the problem. My task - to install the bootloader on the virtual machine image. The image contains the MBR and the only partition with the file system ext4. The file system contains all the files for the guest OS. To install bootloader into the image of the guest OS, I use the

I am trying to install CentOS from an ISO image file but the installer does not see a CD-ROM drive. The VNC viewer works but the CentOS installer indicates "Unable to find any devices of the type needed for this installation type." Then it prompts with "[Select driver] [Use a driver disk] [Back]". I have tried several variations of the "disk" paramater, all

Heh, I like your understatement. :) I think this helps answer part of my questions in my second email: I should probably try to preserve changes from last backup before getting too deep into a tricky e2fsck. At one point the fs was still mountable, so I

Hi all. I''ve got a domU that exists in a sparse file image, I''d like to now use this on a physical partition (loopback performance issues). Is there an a easy way to do this ?

Hi all I want to shrink one of my LVM based domU''s, but don''t quite know how to do it. I have searched the Wiki & HOWTO''s, and they all show you how expand / enlarge a LVM based domU, but not shrinking it. So, I stopped (destroyed) the domU, and then resized it as follows: lvresize /dev/data/cpanel1 -L10GB (It was 100GB), but when I a started it up again, I
