General :: Add An IDE Drive To An Existing Server?
Jul 1, 2011
I recently ran across a client that wanted me to set up a new IDE Drive in his existing Red Hat Server. I reluctantly agreed to try. I am completely uneducated in Linux and could use some input. The server itself appears to be set up in text mode as all that I see is text after the initial boot up screen goes away. It, at present is set up in an old dell machine on a 3 Gig drive and all he wants is to be able to add a secondary drive to extend storage capacity. What do I need to do to prepare the drive and OS to accomplish the task? The secondary drive is 120 Gig. I reformatted the drive, as a fat 32 and installed it into the machine. The board sees it. The network does not
I have an existing unix user that some how didnt make it into the copy over to our LDAP server. How do I add an existing unix user to an existing LDAP directory? Will ldapadd work? I was under the impression ldapadd required an ldif file to work properly.
I have a SATA hard drive from a crashed system that was running Ubuntu 8.04. I want to install it in a Ubuntu 8.10 system and use it for file storage. How do I install and reformat it?
I had a drive that kept kernel panic'ing so my data center recommended using the spare hard drive to reinstall OS on, and import the data from the old drive. (they checked the hardware, it wasn't the hardware) The new install is done, and I need to mount the old drive and get backups off it since my data center does not provide management whatsoever.
It's the same OS on both (Cent OS 5.4 32-bit) I'm an advanced user on windows, but linux gets me. I can ssh in, do basic stuff like setup IP ranges and restart services. I normally navigate the box through SFTP so I have a gui. WHM shows me my drives as such
Found Disk: hda Found Disk: sdb
so I'm assuming SDB is my old drive and the drive I need to access. I attempted to follow instructions on
I am using ubuntu 10.10 (maverick meerkat), and i am loving it. While installing, i hadn't created multiple partitions. But now i feel the need to create a few. How can i repartiton the hard drive without reinstalling?
I have an issue with VirtualBox. My current setup is a machine running Fedora 10 with 1 Tb of disk space. I installed VirtualBox and created a fixed size disk image of 50 Gb for a virtual Windows XP64 OS. Now I require more disk space with additional 100 Gb. Is there a way to add another partition to the virtualized OS as if I added a new hard drive to the system?
In other words, I'd like to create another disk image by using additional space from the same physical drive and mount it under Windows XP in VirtualBox.
I want to move my "currently installed Debian and its all settings" to a USB flash drive. I am wondering what methods are available out there. I looked into Remastersys but it failed on my system so I am wondering if there is another method available?
I have an existing Fedora 15 system installed from scratch.I've ordered a harddrive identical to my SDA and want to add it to my existing system as a RAID1 setup.I've googled around and cannot find recent clear instructions how to accomplish this. I don't want to reinstall everything from scratch. It should be possible to create the RAID1 using the existing data disk and then mirror everything up?
I want to be able to add a physical drive to an existing filesystem, and PRESTO! That filesystem has more storage and/or redundancy. When one of the physical drives eventually fail, no problem, Ive lost some redundancy, I just have to install a new drive before another one fails.Lets assume I have 4 physical drives.*What Is This Configuration? *[URL]...But I am unclear how to get a logical volume that is mirrored and linear.
The last time I tried software RAID 1 (dm-x) under lvm, it was very fragile. Systemd could not start it,and then an update to mdadm put a stake through its heart. So I know that does not work.
I have successfully installed 11.04 onto my existing Windows laptop as files contained in the windows system and have dual booting.I would like to copy this installation to a 5gig fast usb stick so that I can retain all my settings etc
I have Fedora 12 installed on an external harddrive (USB) and have it configured the way I want. Inside my laptop I'm working on I have a Win 7 installation. My plan is to slowly migrate to Fedora and only use Win 7 when needed, so far so good..
I shrinked the partition on the internal drive holding using Win 7's built in tools and would like to clone my USB installation to the new partition I can now create, I work a lot with Macs in my line of work and there I always use Carbon Copy Cloner to make bootable backups, works like a charm..
As far as I know CCC uses rsync which is available for Linux as well so I guess I could use that? I plan on editting the Win7 bootloader later on to make it possible to boot from the new Fedora partition.
How would I go about it? The internal drive is GUID (or is it GPT?) formatted and loosing the Win 7 installation isn't an option of course.. All I could find were commandlines to backup certain folders or entire drives but I only want to backup my partition onto a different partition..
I 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.
I am trying to install ubuntu 9.10 on an system which already has XP installed. I had used Ubuntu earlier but when I installed XP ( in an attempt to dual boot) I seem to have lost the Ubuntu Installation. But the problem is GParted or the Ubuntu installer dont recognize the existing partitions but instead see it as an empty unallocated drive. I have a 120GB hard disk. Below is the extract after fdisk:
Disk /dev/sda: 120.0 GB, 120034123776 bytes 255 heads, 63 sectors/track, 14593 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x4fa8a60b Disk /dev/sda: 120.0 GB, 120034123776 bytes 255 heads, 63 sectors/track, 14593 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Disk identifier: 0x4fa8a60b .....
Also this is how the disk Utility in Ubuntu sees my system: ( See attachment) [IMG]file:///D:/Screenshot.png[/IMG]
I have a home network that includes a couple of computers {A, B, C, D}. currently, I have a cron jon that runs every minute and updates (using rsync) the hard drives of computers {B, C, D} with the contents of hard drive {A}. So far everything works great, as hard drive {A} barely has any information on it. Now, I am about to copy a lot of information (about 8 GBs) to hard drive {A}. Naturally, the cron job will run (as it runs every 1-min) and try to 'sync' the contents with hard drives {B, C, D}.
Given my network (100Mbit/sec), there is no way the cron job will be able to 'copy' the contents to hard drives {B, C, D} in one minute. It will take much more time. Does this situation create a problem? meaning, will cron re-run a new rsync instance 1min later, even though an existing rsync process is running and still copying information to hard drives {B,C,D}? Will my backups be hurt / slowed down tremendously because of this?
I am currently running Ubuntu 8.10 amd64 on a single 750GB drive. My question is whether or not I can add two more drives (say 2 500GB drives) in a raid 0 array leaving the OS and data on the original drive? I find my self working with some very large files and I would like to speed up their processing time. At the same time, I would like to leave my current configuration in place without touching the OS or my data. I'm not much of a hardware guy.
We 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.
Currently I have 3 hard drives 2pcs 10gb almost the same 1pc 20gb
I have a layout of (10.2gb) /dev/hda1 boot 104391 83 Linux /dev/hda2 9912105 8e Linux LVM (10.1gb) /dev/hdb1 9873328+ 8e Linux LVM (20.4gb) (unpartitioned)
The two 10g is setup as lvm and I want to make raid1 using the 20gb hdd. Almost all I see is raid1 first in the internet.
I am working on setting up some networking connections here. [URL]. Depending on your router make and model. You can disable the dhcp server on the router if you go to advanced setup and in the dhcp option You should find two radio buttons off and on click off and you will disable the dhcp server on the router refer to your router documentations. I do not wish to disable the DHCP on my router (2wire). I have fixed the router so it assigns static IP addresses - by following the Management and Console Diagnostic" portion on this page: [URL]. There are 7 machines getting IP addresses from the 2wire router. Of the 7, I have configured 4 to have static IP addresses allocated to them by the router.
For example, the domain here is : 2wire.gateway.net If I have a host named "zazu", and I ping zazu.2wire.gateway.net, I get the right IP address. I am working with a product (ZIMBRA) that -> requires for the host to "have MX records". -> that you get a FQDN when typing "hostname" -> that you get a FQDN when typing "hostname -f" Basically, the way it is supposed to be set up is: ZIMBRA (internal) <----> Kerio Mail Server (Windows) <---> email from the outside world
So, in a sense, the Kerio Mail Server is to forward mail received from the outside world to ZIMBRA and ZIMBRA is to send mail to the Kerio Mail Server to send it to the outside world. From what I see at these links: [URL] And [URL]. You have to set up some kind of DNS server? Why? Don't both the DHCP server and DNS server serve the same thing? How can I incorporate a DNS server into my setup when the 2wire (with DHCP) is working just fine?
I have a system that has the following partitions:
Now SDC is a new drive I added. I would like to pool that new drive with the raided drives to give myself more space on my existing system (and structure). Is this possible since my raid already has data on it?
I have a RAID5 with 5x2TB HD's and I'm planning a major hardware overhaul. My server currently runs on a Pentium4 3.2 Ghz (pre multicore technology) on a SuperMicro mobo. I'm planning to switch to an AMD Phenom II X6 1100T Black Edition Thuban 3.3GHz, 3.7GHz Turbo 6.
So here's the question. Can I just plug my drives to the new board and restart the RAID like nothing happened? I don't have space to backup all my data if I have to recreate the RAID from scratch. Intel and AMD should be binary compatible (I mean the RPM's work) so I should be able to invoke mdadm to assemble the RAID after I install Linux on the new server. Right?
I have an existing proxy server which connects to my main office in London. I would like to move this server to a guest in Xen environment. Or i can install the proxy server on the guest and copy some relevant files? But please note that the environment is slightly different
Old Server: Redhat 4 with proxy 5.1 New Xen guese: Redhat 5
is there a way to clone an installation? I have a couple "master systems" which I want to replicate into other servers. In Solaris I can build a flar image from the first one and install from that image, I looked into cobbler and koan, but they seem to be more repo and kickstart oriented.I need a way to say "take this system as a base and build an installation image out of it".
we have an existing debian server which host our moodle installs , but i need to look at converting to virtual and host within our test network for breal fix testing... but i cant find anything that will allow me to convert it as it stands.
we use Virtual machine manager, i would like to have used Redhat but its a no no ...
At present, In web server 97% space has been occupied in /usr/share/squirrelmail partition. Therefore, we need to increase the partition of our existing storage device (NAS Storage box) either by creating new partion or merged the same along with the existing partition.

Alternate Heading: Unable to use opensuse partitioner to fully format a Seagate 1Tb drive OK. Swapped over a motherboard to increase the number of slots available for hard drives so that I could expand my raid array (4 X 1Tb drives). Discovered I had no thermal paste so all delayed for 24 hours while I bought some, miscalculated on rebuild and had to reinstall OpenSuse but in the end system is now up and running. Unfortunately when I formatted my new 1Tb drive (Seagate) it formats to 931.50 Gb while the other 4 drives formatted to 931.51 Gb (they are WD). I'm now in the position that when I try to add this new drive I get :
mdadm: /dev/sdc1 not large enough to join array
Is there any way I can resize the existing devices down to 931.50 Gb so that I can add in the new drive without having to restore the array?
I have CentOS 5.3 dual booting with Vista on a machine with AMD-V support. I'm looking to get my existing Vista partition running as a DomU Xen machine. Can this be done without having a dedicated video card?I've got a Xen kernel (from the repositories) installed and running perfectly with my nVidia graphics card. I tried to set up a new DomU through virt-manager and set it up as Vista, pointed it at the physical partition (fakeRAID mapper device) and gave it 2Gb RAM (I have 8Gb total). I got it to do a PXE network boot, knowing that this would fail and therefore no installation would be attempted, as no installation is needed.
This worked well in that the initial PXE boot failed and the machine shut down. When I start it now it seems to actually boot Vista, but I just can't see it! It goes as far as saying "Booting from Hard Disk..." in the viewer window and then doesn't update, although the disk activity and CPU usage are very similar to a machine booting Vista to the login prompt.
We have been using Ubuntu Server at our department since several months now. It hosts a website, e-mail and nfs(only intra).
It was set-up as RAID 0 with two 1TB Hard drives but I want to change it to RAID 1 for fault tolerance. Is it possible to change existing RAID level? If yes can someone point me to the proper place?
I tried "mdadm" documentation and level set option is available but no explanation available that whether it is only while creating the array or it can change the level too.
