similar to: When should LVM be used?

Dear CentOS-Community, we have a server with four hard drives that are configured as raid10 (/dev/sda). Now, /home and /root are almost full. Therefore, we decided to buy four additional hard drives that should configured also as raid 10 (/dev/sdb). I want to use LVM to extend disk space for root and home. My (successful) test procedure in a virtual environment looks like this: 1. devide

Hi, I have a working windows lvm of 1.62GB size. I just do an lvextend +1Gb on it, and then the Guest gets stuck at ''booting from harddisk'' the initial stage. Is there something more I should do? I had tried getting it working with parted etc, but it doesn''t seem to work. Is there some documentation on manipulating windows image files and the partitions inside them?

I have a disk on which CentOS is installed and running. The disk partitions look like this: Disk /dev/sda: 42.9 GB, 42949672960 bytes 255 heads, 63 sectors/track, 5221 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 * 1 13 104391 83 Linux /dev/sda2 14 1044

I now how to expand a LVM by creating a new drive as described here: http://lists.centos.org/pipermail/centos/2007-February/032664.html, the steps are: # pvcreate /dev/sda3 # vgextend VolGroup00 /dev/sda3 Now, I want to know how to expand a LVM without create /dev/sda3? Suppose I have 2 GB free (unpartitioned) and LVM use /dev/sda2 (8 GB). How to make /dev/sda2 become 10 GB? Then resize LVM

Hi, I'm trying to resize a 15GB LVM root partition on a fedora20 server with a fedora20 guest and I'm having a problem. Is this supported on fedora20? I recall having a similar problem (maybe even exact same problem) all the way back in fedora16 or fedora17, but hoped/thought it would be fixed by now? # virt-df -h test1-011015.img Filesystem Size Used

I've replaced disks in a hardware RAID 1 with larger disks and enlarged the array. Now I have to find a way to tell LVM about the extra space. It seems there are two ways: 1. delete partition with fdisk and recreate a larger one. This is obviously a bit tricky if you do not want to lose data, I haven't investigated further yet. 2. create another partition on the disk, pvcreate another

Hi To deploy KVM vms I use a KVM template + script - which is cloned, then cloned again and resized - using virt-resize. i.e ---------------------------------------------------- virt-clone --original debian6template-DONTSTART --name NAME.test -f /dev/vgpool/NAME.test virsh vol-create-as vgpool NAME 8G virt-clone --original NAME.test --name NAME -f /dev/vgpool/NAME virt-resize --expand

Hello everyone! I faced an issue using virt-resize. I have an image with extended -> logical -> pv -> lv -> ext4 (although I think LVM does not matter). And image is 65G virtual size and 1G actualSize. When I call virt-resize to 60G, it blindly copies the extended partition content, but does it non-sparse (resize.ml:1231), irrespective to --no-sparse option. So the destination image

I've been reading the RHEL 5 manual/guide linked from centos, and the idea of LVM with expandable partitions seems like a great idea (yes duh why else would it exist if not?). Although the documentation shows a screenshot of how the final setup would look like with LVM & RAID together, it doesn't actually gives the step. 1. Am I correct in thinking it should be done in this way -

Side note: In CentOS-6, I noticed a new option in lvresize / lvextend: -r, --resizefs Resize underlying filesystem together with the logical volume using fsadm(8). Nice. Two steps (lvresize and resize2fs) can now be combined into one! Works great. But that has nothing to do with my question, just thought I'd share the discovery. == Anyway, here's

Hi Rich, This is v3 series to add support for resizing MBR logical partitions. changes to v3: 1. merge patch 1 and patch 3 in v3 2. let mbr_part_type return 'primary' for GPT partitions 3. add test for resizing logical partitions 4. fix extending the extended partition (yet). see patch 7. changes to v2: 1. remove p_part_num 2. remove filter_parts 3. name the function

I have a report for 1.20.4 about this error. There is no /etc/lvm/lvm.conf in the guest, which is handled as fatal error. Creating an emtpy file with that name is a workaround for the time being. $ virt-resize --expand /dev/sda2 in.img out.img Examining in.img ... Fatal error: exception Guestfs.Error("lvm_set_filter: open: /tmp/lvmiUFSBa/lvm/lvm.conf: No such file or directory") Maybe

I came across an old post comment yesterday (from http://echenh.blogspot.com/2010/04/how-to-extend-lvm-on-vmware-guest-os.html ) discussing the "hack" of LVM on Linux VM guests and whether it's better not to use it to simplify disk management. I've re-posted the comment below, does it sound reasonable? Is it better to not use LVM on Linux VM guests? --Russell

Hi, ? I am searching around and I can?t find any GUI LVM manager included in a Centos live CD. ? I am trying to resize a LVM partition in a Centos 6.9 machine with a live CD. ? If I need any other distro, It?s fine with me ? Thanks! ? Miguel ?

Hello: We trying to configure one machine (Compaq Proliant ML760) with 8 disks (72GB each disk) with RAID. We are thinking to use ext3 and LVM in RedHat 7.2 for manage one filesystem with 500GB. This filesystems have to store near off 5.000.000 of files. Is this possible? Could I resize the filesystems/volume to 1TB? what are the ext3 and LVM limits? someone have tested sismilar environment?

I notice this question on the wiki/faq: https://btrfs.wiki.kernel.org/index.php/UseCases#What_is_best_practice_when_partitioning_a_device_that_holds_one_or_more_btr-filesystems and as it hasn''t been answered, can anyone make any comments on the subject Various things come to mind: a) partition the disk, create an LVM partition, and create lots of small LVs, format each as btrfs b)
