similar to: Extending an existing LVM pool - vgextend and pool XML

I looked around but could not find any info on how to expand a libvirt managed LVM storage pool. I do not see any virsh command to do it but I was successful using the vgexpand command to add some more storage once I destroyed the pools and then restarted it. I'd like to verify that this is the proper way to grow the storage in a libvirt LVM storage pool. And this brings up a second

Hi, I've found a problem with supermin code running in an ibm_powerkvm ppc64le distro.

Hi all, I've got some problems to make work oVirt. I've installed a Fedora 10 VM the lightest possible (nothing checked, even based) and installed after some packages (wget, sudo, acpid,...) and updated the system. By the way, acpid should be a dependency of ovirt-installer because the installation fails if it's not available. I've then installed ovirt (ovirt-server-installer

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

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

I have a laptop that I put centos 7 on and I started out with a 30gig partition.? I resized the other part of the disk to allow more space for centos.? I then created an unformated partition in the available space,? ran pvcreate /dev/sda4 vgextend lvname /dev/sda4 lvextend -L 184.46G /dev/lvname/root but when I run: sudo resize2fs /dev/lvname/root I get: resize2fs: Bad magic

Hi everyone. This isn't specifically a CentOS question, since it could apply for any distro but I hope someone can answer it anyway. I took the following steps but was puzzled by the outcome of the test at the end: 1. Create a RAID1 array called md3 with two 750GB drives 2. Create a RAID1 array called md9 with two 500GB drives 3. Initialise md3 then md9 as physical volumes (pvcreate) 4.

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

This is the same as the previous patch, but the partition type is now chosen automatically from mbr or gpt, unless the user expresses a preference. https://gb.redhat.com/archives/libguestfs/2012-January/msg00136.html Rich.

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

Hello All, I 've gotten myself into trouble by running out of disk space.

I'm still running CentOS 5 with Xen. We recently replaced a virtual host system board with an Intel S1400FP4, so the host went from a 4 core Xeon with 32G RAM to a 6 core Xeon with 48G RAM, max 96G. The drives are SSD. I was recently asked to move an InterBase server from Windows 7 to Windows Server. The database is 30G. I'm speculating that if I put the database on a 35G

Not a centos specific question here, but if anyone can save me from shooting myself in the foot would appreciate any pointers.... I have an older centos 4.7 box that I recently replaced with a newer one running centos 5.3. I'd like to add the hard disk from the older one to the newer one before I scrap it for good. I don't care about the data on it, would just like the extra drive

I've used LVM on servers with hot-swap drives to migrate to new storage without downtime a number of times. Add new drives to the system, configure RAID (software or

Hi all! I've got a VM at work running C6 on HyperV (no, its not my fault, that's what the company uses. I'd rather gag myself than own one of th ose things.) I ran out of disk space in the VM, so the admin enlarged the virtual disk. but now I realize I don't know how to enlarge the partition and its filesystem. I'll be googling, but in case I miss it, it'd be great if

I read your version of the procedure and it looks like you want to skip the pvmove. That's fine, but it means more downtime (an unreliable estimate is one minuted per GB). In that case, you don't even need the snapshot. You won't need a point in time
