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.

Hello..I am not very proficient in Linux kernel stuffs although I know my basics. I have a question and all suggestions/solutions will be highly appreciated... I got to know that RHEL 5 has inbuilt Xen Support...So I tried to install a RHEL 5.0 Server on my P4 machine. On top of it I tried to install Xen specific RPMs and some other RPMs needed by Xen. The additinal RPMs added after base

Hello, I'm in a slightly unusual situation and I'd really appreciate some advice. I installed CentOS 5.2 on a server about a month ago. Today I happened to check the 'free' command and noticed that the Swap line reads as follows: Swap: 0 0 0 I'm pretty certain that when I installed the OS and created a custom partition table, that I defined a

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.

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

After upgrading my HD, I am now wishing I left some space for doing snapshots. Is there a way to free up some space so I can get some free PE? Right now I have this: # vgdisplay --- Volume group --- VG Name VolGroup00 System ID Format lvm2 Metadata Areas 1 Metadata Sequence No 7 VG Access read/write VG Status resizable

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

Hi People I just updated a CentOS 5.2 Server that is a Guest inside VMware ESX 3.50 Server using "yum update". As far as I can tell the only three packages were updated Jul 24 16:37:49 Updated: php-common - 5.1.6-20.el5_2.1.i386 Jul 24 16:37:50 Updated: php-cli - 5.1.6-20.el5_2.1.i386 Jul 24 16:37:50 Updated: php - 5.1.6-20.el5_2.1.i386 But when I rebooted the Server one of my

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

I've been running into a reproducible problem when using default LVM volume group names to present block devices for virtual machines in KVM, and I'm wondering why it is happening. On dom0 I make a default VolGroup00 for the operating system. I make a second VolGroup01 for logical volumes that will be block devices for virtual systems. In VolGroup01, I make two lv's for one system:

Hello: I have set up a DAV file system on my apache server using these directives in ssl.conf: Alias /files /var/www/files <Directory /var/www/files> Dav On AuthType Basic AuthName "Filesystem access" AuthUserFile /var/www/files.passwd require valid-user Options Indexes </Directory> On my client machine (Windows XP SP3), I am able to add the https location

Hi, I want to rename some volume groups and logical volumes. I was not surprised when it would not let me rename active volumes. So I booted up the system using the CentOS 5.5 LiveCD, but the LiveCD makes the logical volumes browsable using Nautilus, so they are still active and I can't rename them. Tried: /usr/sbin/lvchange -a n VolGroup00/LogVol00 but it still says: LV

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

How do I mount a partition that is in an image file? I have a file called centos.img that has 3 partitions in the file. I need to copy data to the third partition on that image file. I have seen things about a loop back device (which is fine) but then it talked about an offset parameter and I dont know what that is or more importantly what number to use. I hope I'm on the right track. How

I am trying to mount this (my old hard drive) from my Centos 5 install as a USB drive so I can copy files over. I have made the change to max_luns so that I can have more than one drive on a USB drive. The first partition, /dev/sda1 mounts automatically as /boot_ The second partition, /dev/sda2 is the one I really want and it is an lvm partition. When I am booted from this drive (as the

I began an update of one of our servers via yum and, coincidentally or not, I have been getting the following logged into the message file since: messages:Jan 7 15:55:51 inet07 kernel: post_create: setxattr failed, rc=28 (dev=dm-0 ino=280175) Now, this tells me that dev dm-0 is out of space but, what is dm-0?

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

I''ve spent the past while researching this but I''m just not finding a solution. I''ve been trying to get my xen kernel booting on a pretty much stock CentOS 4.4 installation. I installed Xen from src rpm and installed all the requisite software and I''m sure it''s with the ram disk but I can''t figure out how to resolve this. With a stock kernel

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
