similar to: How to expand LVM without create new drive?

Hi This topic is perhaps not for this list, but it I'm running on a CentOS 4.4 and it seems that a lot of people here uses 3Ware and RAID volumes. I did a RAID migration on a 3Ware 9590SE-12, so that an exported disk grew from 700GB to 1400GB. The exported disk is managed by LVM. The problem now is that I don't really know what to do now to let LVM and my locigal volume to make use of

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

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 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 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

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

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'm having some difficulty finding a method to shrink my /home to expand my /.? They both correspond to LVMs.? It is my understanding that one cannot shrink a xfs filesystem.? One must back it up (xfsdump), remove (lvremove) redefine it and then restore it back (xfsrestore). Okay, I'm running into a problem where /home? needs to be "unused".? If tried going in to

I have a database server that is running out of space. All my databases are being stored in a 80G /opt partition. Because I'm using LVM, wouldn't I be able to pop the HDDs (a h/w raid volume) in, add it to the LVM, and resize my ext3 /opt partition? Everything that I've been reading says this is possible, but I'm not sure. Has anyone done this and are there any pitfalls to

Hi all, I have a disk of 146Gb in a machine intended to have mainly mysql database, apache and some web data.?

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, Is there a way to make a PV xen guest aware of a size change of the host disk? In my case I'm talking about a Centos 5.3 host using logical volumes as storage for the guests and the guests running Centos 5.3 and LVM too. What I'm trying to accomplish is to resize the logical volume for the guest by adding a few gigs and then make the guest see this change without requiring a

Hello all, I posted the whole disk encryption instructions in the forum that has been briefly discussed on the list. I joined the list per Ned's post on the thread. http://www.centos.org/modules/newbb/viewtopic.php?viewmode=flat&topic_id=15923&forum=42 I have a couple of questions about the process of creating a wiki. 1. How does the peer-review process work? 2. Is there a place

Hi everyone, I added a page under the HowTos for Encryption, and then added a guide for encrypting /tmp /swap and /home using cryptsetup and LUKS keys on LVM, when you already have partitions setup. http://wiki.centos.org/HowTos/EncryptTmpSwapHome Regards, Max

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

OK, I wanted to replace the 500G disks in a Dell T20 server with new 2TB disks. The machine has 4 SATA ports, one used for the optical disk and three for the hard drives. It is set up with /dev/sda and /dev/sdb with each three partitions: 1 -- VFAT (for EFI) 2 -- ext4 (for /boot) 3 -- LVM /dev/sda2 and /dev/sdb2 are a mirror raid (/dev/md0) /dev/sda3 and /dev/sdb3 are a mirror raid

I think I have solved my issue and would like some input from anyone who has done this for pitfalls, errors, or if I am just wrong. Centos 5.x, software raid, 250gb drives. 2 drives in mirror, one spare. All same size. 2 devices in the mirror, one boot (about 100MB), one that fills the rest of disk and contains LVM partitions. I was thinking of taking out the spare and adding a 500gb drive. I
