similar to: CentOS 6, Raid 1, and LVM

Hi all, Please excuse the many posts. Wondering if any one can help me with the the setup. I have 2x2TBdisks. I would like to mirror them. I would like to create two LVMs so that I can snap shot from one to the other. During Centos 6 install, how would I go about this as its confusing? So far I am here; 1) Created the following raid devices; md0 500MB (use it for /boot) md1 4000MB (use it

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 all, Does any one know of a how to for creating raid 1 + LVMs during install for Centos 6? Do I create the physical LVM first and then raid or vise versa? Its seems diff then doing it for Centos 5. - aurf

Hello listmates, I have encountered a rather peculiar situation. We have a Centos 6 VM (64 bit) running on a VMware vSphere 5.5 server. It was running just fine until one day I decided to reboot it and it just would not boot up. Effectively, dracut failed to initialize the LVM, much like under the scenario described here:

Hi. I have some narrow questions and a larger one. If I make an existinig LVM VG a storage pool, can I use some of the LV's for libvirt and some for the host? Or does the VG needed to be completely dedicated to virtualization? Assuming mixed use is possible, is it possible to do an LVM snapshot of an LV in use for a VM? The snapshot would have to be initiated and used on the host, I

Hello all, I''ve been searching through the archives and the internet for a while now, and can''t seem to find anything that helps me out. I hope you don''t my posting this to both xen-users and linux-lvm simultaneously, but i figured it''d help keep the solution in one place... even though it''ll be the same across two places... Anyways: My setup is this:

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

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,

I have 4 virtual servers, all 4 run fine on the xen-unstable I downloaded with a nov 16 date I download the latest 3.0 testing or unstable and I can only run one at a time, I start one it runs, I go to start any other one ( in any random order even ) and I can''t, get errors about my lvm already in use by another guest. I have 4 seperate lvm ext3 partions and 4 seperate lvm swap

Hi, I have a system running CentOS4.8. Last month I installed the latest updates including kernel 2.6.9-89.0.23 and rebooted the system. It has been running for almost a month. Last night I updated the system again which updated only a few packages: openssl, tzdata, curl,vixie-cron and logrotate. No new kernel or anything out of ordinary. The reboot after the update stopped with kernel

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

Sorry for my ignorance. When I create xen virtual machines on lvm I need to create a filesystem on lvm container? _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users

Hey, group, I've got a system installed on a VMware VM. The SAN administrator allocated me more disk space from the (EMC) SAN and I need ultimately to create another partition to mount on the filesystem. Two (initial) questions about this: What steps do I need to take prior to creating a new partition with fdisk? (The SAN space, BTW, is connected through VMware.) The OS is already

CentOS 5, original kernel (xen and normal) and everything, Linux RAID 1. I rebooted one of my machines after doing some changes to RAID/LVM and now the two RAID partitions that I made changes to are "gone". I cannot boot into the system. On bootup it tells me that the devices md2 and md3 are busy or mounted and drops me to the repair shell. When I run fs check manually it just tells

Just wanted to share some success I had moving some Xen guests from one server to another. Problem Recap We had Xen host on a single core 32-bit CentOS 5.4 installation on an AMD Athlon 2.1 GhZ system that was giving hard drive errors and needed to move the LVM-backed Xen images to another server. The replacement server was a quad-core AMD Phenom system running 64-bit CentOS 5.4. Our original

Hello: We trying to configure one machine (Compaq Proliant ML760) with 8 disks (72GB each disk) with RAID. We are thinking to use ext3 and LVM in RedHat 7.2 for manage one filesystem with 500GB. This filesystems have to store near off 5.000.000 of files. Is this possible? Could I resize the filesystems/volume to 1TB? what are the ext3 and LVM limits? someone have tested sismilar environment? I

Hi all, I'm setting up Centos4.2 on 2x80GB SATA drives. The partition scheme is like this: /boot = 300MB / = 9.2GB /home = 70GB swap = 500MB The RAID is RAID 1. md0 = 300MB = /boot md1 = 9.2GB = LVM md2 = 70GB = LVM md3 = 500MB = LVM Now, the confusing part is: 1. When creating VolGroup00, should I include all PV (md1, md2, md3)? Then create the LV. 2. When setting up RAID 1, should I

Hello list, I'm trying to install CentOS 5.2 on LVM on a SW-RAID level 1, but I'm unable to understand how to use the installer correctly. What I'm trying to do is emulate something I've already done with another distro where: sda5 \ RAID1 --> /boot sdb5 / sda6 \ RAID1 --> LVM --> /root, /home, /usr, /var... etc. sdb6 / I've succesfully

Hello, I wonder if we can use RAID (hard) under LVM for Xen domU. What kind of RAID is recommanded ? I was thinking about the following configuration: - RAID 1 (two 70 GB disks) for the dom0 - RAID 5 (three 285 GB disks) for domU on LVM partitions Any idea ?
