I added a Volume group in Proxmox VE as Storage for KVM VMs. A new Logical Volume will be created for each VM, but in Proxmox VE under The Defined Storage which shows list of created Logical Volumes I see my Logical Volume marked as RAW format. Is this a RAW image or a Logical Volume (LVM)?
I have an LVM2 logical volume that is formatted with ext4 and mounted to a directory on /opt. On that volume is a qcow2 KVM image for a Windows 7 guest. Can I snapshot the LVM logical volume for a complete backup/clone of the VM?
Got a 2008 server in production , which currently has "one" disc. (Actually a SAS array, presented as a single disc to the OS.)
This "disc" is partitioned into a few sections, with some free space left over.
Someone has the app on the server running off of the C: partition. A bit of lag was sensed and we presumed that the OS tasks might be slightly affecting the app performance.
Linux initially comes with hard drive partitioned and Logical volume made. What is that used for? On /dev/mapper, I see logical volume named after my computer and it has /home and such.... [by shuhei]
I am setting up a machine to run a number of virtual machines. I am using a single HDD with a boot partition and an LVM partition.
I have an existing CentOS 6.2 system with drives having this partition:
sda
--sda1 - ext4 - /boot
--sda2 - physical volume
Logical Volume
--VolGroup
-----lv_root
-----lv_home
-----lv_swap
sdb -free
I made RAID1 by using the sdb first. md0 (ext4) and md1 (physical volume). How can I copy the logical volume in sda2 to md1?
Is it possible to create a volume group from a logical volume instead of a physical volume? If so, are there any pitfalls in doing so?
Use case:
Installing OpenStack Compute on a a system that already has all of the physical volumes assigned to a singe volume group. The nova-volume service requires a separate volume group, as described in the documentation.
I have a Dell PowerEdge r510, with 5 HDDs in a RAID6 configuration. I'd like to add a 6th disk (and, in the future, more) to grow the hardware RAID configuration. I have a logical volume, in which the current disks are all physical volumes.
hi I use gparted to get 5GB from windows partion ^_^ and fedora is on Logical volume. now I don't know how to extend logical partition. Can anyone help me??
Code:
[root@Nyan ~]# lvextend -L27G /dev/vg_nyan/lv_root
Extending logical volume lv_root to 27.00 GB
Insufficient free space: 2274 extents needed, but only 0 available
