General :: Mirror The Boot Partition On Existing Raid1?
Feb 26, 2011I have a raid1 setup on a machine. Recently it died and I thought one of the drives had failed as it was shooting errors. So I tried unplugging that drive get it to boot off the mirror but it seems the techs forgot to mirror the boot device so the 2nd drive can't boot on its own. After a while it was realized that the sata cable was in fact bad and replaced so now its working again.
However, this occurrence showed a flaw in the setup where the RAID1 isn't working as its supposed to. I would like to correct this. Can I somehow mirror the boot partition so the 2nd drive will boot independent? I'm not sure how I would go about this. This is a CentOS 5 installation.

View 2 Replies View RelatedRed Hat :: Adding A Root Mirror Drive To Existing RHEL5 System?
Nov 9, 2010I have a running RHEL5 system, which has two physical disk drives, but is currently running on a single drive of the pair. The single drive the system is running on contains a root/boot partition and a swap partition. I would like to be able to add a mirror drive to this existing setup without having to disturb the running system (much). That is, I don't want to have to completely dump, reinstall (creating the mirror on the way up), and reload from backup media if I can avoid it. I have seen procedures that go as follows:
- the "extra drive" (the one not being used as the current root/boot device) is first brought under LVM control as a root object with one physical mirror attached.
- the data from the running root/boot drive is rsync-ed over to the LVM-controlled half-mirror, and boot records added.
- System rebooted on newly created half-mirror.
- Original root prepped to be second side of LVM mirrored root, and is added in.
Can one boot from an LVM disk directly? There seems to be some question on this that came up in other lists I had read online.

Mar 20, 2011I am currently running Debian on a system with 3 scsi hard drives with Raid and have an identical back up server.

CentOS 5 :: Easiest Way To Mirror Existing Server Setup On A New Server?
Jan 13, 2011We have two CentOS 5 servers in production (web and database). We are setting up a single staging server that will mirror the configurations of these servers as closely as possible. What is the easiest way to ensure the exact same software and configs as the production servers are setup on the new staging server. Our contracted data center provider has already informed us that they do not perform images and NO we do not have physical access to the machines. It is undetermined whether we will be virtualizing the staging server into two virtual servers yet, so for the purposes of this post lets assume we are not. I'm seeking a faster/more precise method than doing this by eye and hand.
Some information on our web server code...

Debian :: Creating New Profiles Based On Existing Profile In Gnome
Oct 8, 2010I'm setting up my profile in gnome right now, with things like fonts, themes, wallpapers, iceweasel settings, menu settings, and I'm going to be adding a couple new users. Rather than re-do everything again, I thought I'd just create the new user, copy over my home dir, chown it to the new user and then login to make minor final adjustments, like specifiying where the music dir is and such.Just wondering if there'd be any problems with this, since it's just an idea I think should work but have never tried it. Any experience, or warnings?

Oct 16, 2009This concerns the Logical Volume Manager (LVM).
1) Why would I create a new volume group to add a new hard drive to a system, rather than add the drive to an existing volume group?
2) If I created a new volume group and added a new hard drive to it, would I see the total free space (I see 30 GB now via the file browser)? For example, if I have 30 GB free on the main drive (with the OS), and I add a new drive of say 40 GB in a new volume group (using LVM) would I see 70 GB of free space? That doesn't seem to happen.
Ubuntu :: Hangs Up When Creating LVM Snapshot Of /root Volume?
Aug 14, 2010Recently, I've tried to create a snapshot of my /root folder in 10.04 (I remember to have done so a couple of times without trouble).I used the commandHTML Code: Code: lvcreate -L10G -s -n rootsnapshot /dev/server/root Without a hint of HDD activity, Gnome (?) hangs up - I can move the mouse, and the clock is moving on, but I can't click on anything. No HDD activity, and this goes on forever (after a while, the whole system locks up). This happens each time when I try to create a snapshot.

CentOS 5 :: Kernel Panic Creating LVM Snapshot Of Root Fs Volume
