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

I am trying to install CentOS 4.6 to a pair of 750GB hard drives. I can successfully install to either of the drives as a single drive, but when I try to use both drives and mirror the partitions, I start having problems. Anaconda crashes as it is trying to format the drives. This is what I'm trying to create: /dev/md0: 200MB, /boot /dev/md1: 2GB, swap /dev/md2: rest of the

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.

Hi all, Is it possible, safely, to resize /var while a server is running? I urgently need to resize a full 2GB /var on a running server which is located at a remote location where no one can get to it for 2 days? The system runs on lvm. I already moved /var/logs to it's own LVM partition but it didn't help at all so I think it's better to rather just resize it. Google searches

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

Dear friends: Using Centos 5. I have two physical drives. During install, I made sure to check hdb as well as hda. Both were listed as partitions (which is correct). But my fstab file does not show hdb. How do I make sure that hdb has been formatted and is part of my file system. If hdb is not formatted, how do I format it, please. Sorry for the question. I am a newbie. d[sher at localhost

Hey Roger, I am seeing this weird behavior when using #linux-next + stable/for-jens-3.8 tree. Basically I can do ''pvscan'' on xvd* disk and quite often I get checksum errors: # pvscan /dev/xvdf PV /dev/xvdf2 VG VolGroup00 lvm2 [18.88 GiB / 0 free] PV /dev/dm-14 VG vg_x86_64-pvhvm lvm2 [4.00 GiB / 68.00 MiB free] PV /dev/dm-12 VG vg_i386-pvhvm lvm2

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 Folks, I've inherited an old RH7 system that I'd like to upgrade to CentOS6.1 by means of wiping it clean and doing a fresh install. However, the system has a software raid setup that I wish to keep untouched as it has data on that I must keep. Or at the very least, TRY to keep. If all else fails, then so be it and I'll just recreate the thing. I do plan on backing up

Hi, I am trying to install Gnumeric in CentOS 4 and I can't. It complains about quite a few dependencies failing. It suggested installing some postgresql librairies, openldap librairies... I did that, now I still get: dependencies failed: libmdb/libmdbsq/libsqlite/libxbase/libtds. Is there a yum repository that has them or a yum repository for gnumeric? I have tried Dag, he does not, he

Hi, I have a custom linux system that runs off a FAT32 usb flash disk. I use syslinux to make it bootable and load the kernel. I'm trying to boot now from a SSD SATA disk (500GB) but it's not working and I can't figure out why. BIOS show that no bootable disk were found. What I already tried (linux fdisk): 1- Creating a new DOS partition table on the SSD, a FAT32 (type b), and

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

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 have a degraded raid array (originally raid-10, now only two drives) that contains an LVM volume. I can see in the appended text that the Xen domains are there but I don't see how to mount them. No doubt this is just ignorance on my part but I wonder if anyone would care to direct me? I want to be able to retrieve dom-0 and one of the dom-Us to do data recovery, the others are of

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

Are folks in the Centos community succesfully using device-mapper-multipath? I am looking to deploy it for error handling on our iSCSI setup but there seems to be little traffic about this package on the Centos forums, as far as I can tell, and there seems to be a number of small issues based on my reading the dm-multipath developer lists and related resources. -geoff Geoff Galitz Blankenheim

My previous question: "can syslinux on a USBstik also boot installations on other USB devices ?" got no proper reply, so I'm now including more background detail. The new problem is that my 32bit partition of ETHOberon, only gives a proper font-size under Debian7:DVDinstaller:rescueMode, since I'm forced to use a laptop, after my previous systems were stolen. Neither gnome nor

Hi all, I registe node device lifecycle event callback function after connect qemu. In the callback function, I printf the event and detail. When I plug a USB into host, and then pull out, but there is nothing happen. The callback was not called. Could you tell me Why? And what dose node device mean? I want to auto-hotplug usb devices by using libvirt. Bellow the call of libvirt: // node

Hi Guys, I'm fairly new to Linux and I'm trying to un install a hard drive from my Centos 5.1 box running KDE. When I built the PC, I installed two 500 gig maxtors in the tower, then I installed Centos. Now I've decided that I want to remove the slave drive and use it as an external backup drive - I am mounting it into one of those external drive cases with a built in fan. When I
