Dear James, Thank you for being quick to help. Yes, I could see all of them: # vgs # lvs # pvs Regards, Khem On Sat, February 28, 2015 7:37 am, James A.

Dear All, I am in desperate need for LVM data rescue for my server. I have an VG call vg_hosting consisting of 4 PVs each contained in a separate hard drive (/dev/sda1, /dev/sdb1, /dev/sdc1, and /dev/sdd1). And this LV: lv_home was created to use all the space of the 4 PVs. Right now, the third hard drive is damaged; and therefore the third PV (/dev/sdc1) cannot be accessed anymore. I would like

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.

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

I have a disk on which CentOS is installed and running.

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, This is my current config: /dev/md0 -> 200 MB -> sda1 + sdd1 -> /boot /dev/md1 -> 36 GB -> sda2 + sdd2 -> form VolGroup00 with md2 /dev/md2 -> 18 GB -> sdb1 + sde1 -> form VolGroup00 with md1 sda,sdd -> 36 GB 10k SCSI HDDs sdb,sde -> 18 GB 10k SCSI HDDs I have added 2 36 GB 10K SCSI drives in it, they are detected as sdc and sdf.

Hi guys, I need to move an lvm based domU from one dom0 to another dom0. How do you guys do ths? xm save/restore doesnt have the option to specify lvm target as the storage.

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

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

Hi all, As part of my raid experience, I have yet to have to do this, but was wondering how you guys would attempt it. I have 3 drives in a raid 1, with one as a hot spare. They are 250gb with all space used by two raid devices, 1 with boot, the other with LVMs filling them up. Now, lets say down the road I want to put in 500gb drives and replace them....yikes. I was thinking of taking out the

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

What's the easiest way to transition to a larger HD when using LVM2? I'm running Centos 4.4. I'm going from a 20gb HD to a 40gb HD. I've already DD'd it to the 40gb HD. So now I have 20gb of unused space. Ideally, I'd like to make it one big physical space for the logical space instead of making another physical partition to expand the logical. Here is what I have now

Hi all, I had centos 5.9 installed with one of its volumes (non-root) on LVM: ... /dev/vgapps/lvapps /opt/apps ext3 defaults 1 2 ... Then installed centos 6.4 on this servers but without exporting this volume (I wanted to reuse it). After that instead importing it I did: # pvcreate /dev/sddlmac # vgcreate vgapps /dev/sddlmac And then realised that I should have

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

This hook script tries to address the fact that a RHEV-H installation will format all the storage devices available in the machine in order to create HostVG and AppVG with all the available space. It may be the case that RHEV-H needs to respect and co-exist with a proposed partitioning scheme, not getting all the storage space for HostVG and AppVG volume groups. The proposed solution adds the

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
