Hi, I am trying to recover data from my old system which had LVM. The disk had two partitions - /dev/sda1 (boot, Linux) and /dev/sda2 (Linux LVM). I had taken a backup of both partitions using dd. Now I am booting of CentOS live cd for system restore. I recreated partitions like previous system using fdisk and then used dd to dump all the data onto it. I would like to mount sda2 as LVM, but I

Hi all I have a remote server (i.e SSH access only) which was incorrectly partitioned and I urgently need to get it up and running. It's got a 500GB HDD, but the PV is only 10GB big, so I can't add more LV's to to. P.S. This is on LVM, btw. [root at nd11176 ~]# fdisk -l /dev/sda Disk /dev/sda: 500.1 GB, 500107862016 bytes 255 heads, 63 sectors/track, 60801 cylinders Units = cylinders

I'm running CentOS 5.2, it uses LVM to manage the disks and we had a programmer do something (not sure what) then reboot the system. When it came up it kernel panicked. Luckily it's not production, it was their sandbox. But they didn't backup any of their files. I know the disks are fine because I was able to boot from a linux live cd and mount the /boot partition from the sda

I posted this to the Fedora-list, but thought I might get some additional information here as well. I have a HD that refuses to mount with a 'bad magic number in super-block'. I'm running FedoraCore 6 x86_64. [root at moe ~]# fdisk -l /dev/hdc Disk /dev/hdc: 250.0 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes

Hi, One of our servers has a too small root partition on LVM and needs to be resized. Can / be safely increased online, without a reboot?

Hi, it is possible to create and setup/format volumes on a iscsi storage on one server and than disconnect and attache the storage to an other server. AFAIK on the 'new' server I do have to launch an LVM-scan command ... after login to the iscsi target. But which LVM-command and syntax was it?

Hi all, I need to add a drive with the same LVM labels (i.e. system) to a machine with a drive with the same label. How can I access the data on both drive's LVM partitions at the same time? -- Kind Regards Rudi Ahlers

I've got a situation here where my LVM is showing the following problem: Found duplicate PV xxxxxxxxxxxxxxxxxxxxxx: using /dev/sdb2 not /dev/sda2 Not sure what causes this and I really don't have a clue as to what the consequences are when seeing this or how to fix it. Google just confuses me with any suggestions. Can anyone offer any help, please? Steve Campbell

Does anybody here have any idea how to make an exact copy of a drive that has LVM partitions? I'm having trouble using dd to do this for an EL5 server. We're trying to diagnose a software problem of some kind and would like an exact, perfect copy of the software running so that we can see exactly what the problem is without disturbing our production copy. It's been admin practice

Hi, I have a centos 4 box i use for a file server (nfs and samba). It has two hdd: hda is for the standard install; hdb is for /export/samba/netdisk0 hda is lost - it just clicks now i think hdb is still good i can't figure out how i can remount the hdb disk in a new machine and retrieve the info from it; i've scanned the LVM howto and googled some LVM topics, but nothing seems to

Hi, Sorry for the need of the long winded email. Looking for some answers to the following. I am setting up a xen PV domU on top of a LVM partitioned DRBD device. Everything was going just fine until I tried to test the filesystems in the domU. Here is my setup; Dom0 OS: CentOS release 5 (Final) Kernel: 2.6.18-8.1.4.el5.centos.plusxen Xen: xen-3.0.3-25.0.3.el5 DRBD:

Hi all I want to shrink one of my LVM based domU''s, but don''t quite know how to do it. I have searched the Wiki & HOWTO''s, and they all show you how expand / enlarge a LVM based domU, but not shrinking it. So, I stopped (destroyed) the domU, and then resized it as follows: lvresize /dev/data/cpanel1 -L10GB (It was 100GB), but when I a started it up again, I

Hi, I have CentOS 5.0 which use an old hard disk. And recently I found there are some bad sector on it ... I try to backup my data to other CentOS 5.0 box .... What I did is. I remove the old HD (with bad sector) and install it as a slave IDE on a working CentOS 5.0 ... I try to mount the old HD as /mnt/oldDisk but since it's a LVM, the "mount -t ext3" doesn't work. I'm

Hi, I have exactly the same problem that you experienced in Nov, 2013. I am using ext4 with journaled quota and the quota usage is only updating when I run quotacheck manually. Have you found a solution? Regards, Alex > I have set up user quotas on an ext4 filesystem.

Hi all, One of our Dell servers has failed badly, and one of the domU's has been corrupted in the process. It boots up to a point and then gives me a kernel panic: Loading dm-zero.ko module Loading dm-snapshot.ko module Scanning and configuring dmraid supported devices Scanning logical volumes Reading all physical volumes. This may take a while... No volume groups found Activating

Hi all, I'm not sure if this is the right place to ask, but it's worth a shot. I have installed CentOS 6.5 on one of our servers, and have just installed SolusVM. I have also set up LVM, with a PV on /dev/sda4 (which is GPT formatted, and 3.12TB is size). The problem I'm having is that when I create the VG, it will not show up under /dev/<VG-name>, which it's supposed to

Hi, I recently installed centos for the first time and I like it! Also, I just started working with lvm. The following warnings are genertated whenever I run one of lvm commands on the external usb disk (MyBook by Western Digital). * What could be the source for those messages? * Should I worry about them (writing into the created LV's seems to work)? * If yes, how to fix them?

So here goes... First some back story -Centos 5 with latest updates as of yesterday. kernel is 2.6.18-238.19.1.el5 -setup is raid 1 for /boot and lvm over raid6 for everything else - The / partition (lvm "RootVol") had run out of room... (100% full, things where falling appart...) I resized the root volume (from 20GiB to 50GiB). This was done from a fedora 15 livecd,

Can anybody tell me if it makes a difference if domU''s have separate LVM volume groups? For instance, the Xen User Manual ( http://tx.downloads.xensource.com/downloads/docs/user/#SECTION03330000000000000000) says, when setting up a domU''s disks with LVM, to do a vgcreate vg /dev/sda10 Should each domU have it''s own volume group, or can all the domU''s share

Hello, When I needed to build Xen guests under Debian I could follow more or less the instructions in http://preview.tinyurl.com/2oc48r and the advantage of this approach is that it allows me to setup the Xen guest directly on the LVM partition without making it consider the LVM partition as an entire disk with a partition table. The advantages of this approach are: 1. I can add more LVM's
