Server :: Hardware Migration And Existing RAID
Apr 20, 2011
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?

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 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?

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?

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.

Its from a Synology Box with 3 disks, which one is damaged. But this disk wasnt in use.Take a look on the raid-size of 493 GB - and the both available disks with 250GB..)
On the others there were a linear raid. during this damaged disk the synology-device tells me, that the volume was crashed.But it look like, that this disk was not mounted into this volume.Quote:
DiskStation> mdadm --detail /dev/md2
/dev/md2:
Version : 00.90

I want to upgrade from another distro to ubuntu server for a few reasons. The only problem is I have a lot of data that needs to survive. here is how my computer is setup. I've 5 drives on the computer,
A- 10gb drive for OS and swap only, no data
B,C,D,E - 4x 500 GB drives in a LVM. they make up one large drive with xfs and this volume has about 1.2 TB of data. there is nothing fancy on it, no encryption and no software raid of course the little 10gb drive can be formatted no problem, but the LVM needs to be migrated over intact.

Everything is software raid using mdadm
3x320GB HDDs in raid 5
1x1.5TB HDDs in raid 1(don't ask)
The above are LVMed to create ~2TB of combined space using reiserFS. I'm not really happy with the performance so I'm moving to XFS while I'm at it.
I FINALLY got around to ordering 2 more 1.5TB HDDs. The end goal is.3x1.5TB HDD in raid 5 formatted to XFS for a total of around ~2.7GB of space.
1. Create raid 5 array using the new 2x1.5TB HDDs.(yes, very pointless at the moment, please continue reading)
2. Copy data from 2TB LVM to the new ~2.7TB raid 5. (will mdadm let me be an idiot? It apparently let me force create a single drive in a raid 1)
3. Move the original 1.5TB over to the new raid 5 to actually provide redundancy.

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'm having some (well, a lot actually) of problems trying to get OpenSUSE 11.2 installed on my home PC. I am attempting to set up a dual boot configuration with Windows 7 installed on an bios Nvidia RAID 0.I was able to shrink the partition in Windows, and rebooted onto the net install for OpenSUSE (the MD5 validated DVD install failed multiple burns with "Repository not found"). I get into the graphical installer portion with no problems off the net install CD. However, the installer is not recognizing that there is an existing RAID 0. It lists the 2 SATA disks in the RAID separately. I can click on SDA1, and both SDB and SDB1 and it shows the disks, but does not recognize any existing partitions. If I click on SDA I get an immediate segfault in YaST and drop back to the text mode installer menu. It is loading the nv_sata module just fine.
From forum searches and google it seems that this is not usually a problem. My motherboard is a Gigabyte GA-M57SLI-S4 with the Nvidia Nforce 570 chipset running an AMD X2 64 3800+. Removing the stripeset and redoing it as Linux software RAID is not an option, I do not have enough space for a total backup/restore. Anything I do has to be nondestructive to the existing Windows installation.I really want to have a linux installation but between the DVD installer failing and now this issue I am about ready to give up on it.

I have recently had a problem with my 10.04 server machine. It will not boot, it seems to be taking forever on the loading screen (normally headless server, but I connected monitor when I couldn't ssh), but that's not why I'm here.
Knowing that I do rsync backups every night at midnight of my machine I just bit the bullet and formatted my / partition. Reinstall went fine, I turned off automatic updates (I suspect an update caused the problem) But now I cannot mount my jmicron raid 1, which is where my rsync backup is (doh!).
sudo fdisk -l
Code:
WARNING: GPT (GUID Partition Table) detected on '/dev/sdd'! The util fdisk doesn't support GPT. Use GNU Parted.

I'm running 10.04 x86 server with a really simple installation on a single 250GB boot disk. I then have a RAID5 array as /dev/md0 (set up using mdadm with x4 2TB disks). All is working well. My mdadm.conf file looks like this
Code:
# mdadm.conf
#
# Please refer to mdadm.conf(5) for information about this file.
[code]....
if I was to lose the boot disk and need to remount the RAID array on a fresh installation, what steps do I need to go through. My assumption is that the superblocks on the RAID disks will be used and I don't need to keep any additional information - is this right?

I have two SAS RAID controller cards in a Dell server in slots 2 & 3, both with an array hanging off them. I went to install a third card into slot 1, but then when it boots it says two of my sd's have bad magic number in the super-block and it wants me to create an alternative one, which I don't want to do. If i remove the new card, the server boots perfectly like it did before I added the new card. Is the new card trying to control stuff that isn't hooked up to it because its in slot 1, so its confusing RHEL?

I have a home samba server with a 3ware Escalade 8506-8. I have 5 x 500 gig hard drives in a RAID 5 array. Recently, my 8506 died and I need to get a new one. However, I saw a 3ware Escalade 9500S-12 on ebay for about $20.00 dollars more than a replacement 8506-8.
My question is, if I put my drives on the 9500S, will it recognize my existing RAID array? Or will it want to build a new RAID array and format all of my data?Hope I have asked this question clearly, little short on sleep this week.

I have a Windows 2k server running the AD PDC. 60 desktops users and 6 Windows servers use it as a single sign on server to login. As I plan to install a Centos 5.5 server with Samba for NAS and print sharing, is it possible to migrate the PDC services to the Linux server? I want desktop users and windows servers to authenticate on the Linux server. Is this possible? I have never worked with LDAP services. Worse, should I attempt this migration, it must be completed in a very short time frame.

Im a fairly new linux person and have a hopefully easy question. I am running centos with dovecot and postfix for the mail. Im using imap so all the mail is on the server. Im also using thawte certificates. What is the easiest way to move all of this over to a more stable box? The box i have now is a major POS.

I'm migrating a mailserver from an old to a new mailserver. The new mailserver is based on ISPConfig 3.0.6.1. I would like to migrate what spamassassin learnt in the past from the old mailserver to the new one. Now the question:
- The 2 spamassassin versions are different. Is it a problem?
- Can I just migrate the database with this commands???
Code:
sa-learn --backup > sadb.bkp
sa-learn --restore ./sadb.bkp
-how to migrate SpamAssasins Auto White List and all others SpamAssassins databases?

I have a lightweight admin background, but good enough to set up most servers. I have switched from sendmail to postfix for the first time, but I keep going around in circles on the following. In sendmail, I used to maintain a table (mailertable) where I would redirect email like this
[Code]....
I happily mapped any incoming email address of any valid hosted domain either to go out to it's final destination via smtp, or if the person has a local mailbox, it delivered locally. Any errors could be forced, and a catch-all for the domain could be directed also.
I've struggled with virtual hosts and transport and a combination of the two to come up with the same result for postfix. I have this feeling I'm missing something really simple, or I am not 'getting it' when I'm doing something postfixy and I still have sendmaily expectations. right path so I will at least know I'm pointing in the right direction and working with the right files to achieve my aims? Postfix is so amazingly powerful and flexible, I'm having trouble figuring this bit out.
I have this feeling I just need a calm hand on my shoulder, a friendly smile and a hand pointing me the right way..

I am not new to linux but switching to ubuntu for the first time. I had WAMP server installed in my desktop. I made a small website using php and saved all its contents in the WWW folder within the WAMP folder present in the C: drive, (where windows is installed). Now I have installed Ubuntu. I want to know that how could I make that website work in ubuntu also. Or you can say that I would like to know that WHERE would I paste my website source code files in Ubuntu so that I dont have to work again from scratch and make the website run easily in Ubuntu.

I'm looking into migrating postfix mailboxes and users from an old machine running Fedora5 to a new machine running cenOS. I was wondering, what would be the procedure to migrating over existing postfix mail to the new machine? Is it as simple as copying over /home directories and /etc/passwd etc?

Long time lurker, still a Linux noob but Im learning I currently have a home media server setup with the following hardware specs:
MSI P45 motherboard
Intel Core2Quad Q6600
8GB DDR2 RAM
2x 250GB WD HDD in RAID1 via LVM (boot/swap etc)
8x2TB Hitachi HDD in RAID5 via mdadm (media/data)
The server mainly serves files for HTPCs around the house and runs a few VMs with VMWare server. I have recently picked up the following hardware which I�m thinking about upgrading to:
Gigabyte EX-58-Extreme motherboard
Intel i7 920
12GB DDR3 RAM
My main concern is will I be able to just swap the driving into the new system and everything can just pick up where it left off? More specifically, will mdadm be able to detect the 8x2TB drives attached to the new hardware and re-assemble the array?
My buddy that helped me set this system up isnt sure so I figured I ask here first, the boards do have the same ICH10R southbridge providing 6 of the SATA ports and 2 more will be run off of the extra controller onboard. I dont have a lot of Linux experience switching out core parts but in Windows Ive had great success moving things between various Intel chipsets and architectures from P965 -> P35 -> P45 -> H55 -> X58.

I have a friend that want to migrate his server to a open source mail system. Currently, he's using a system using Maildir. So I decided to use qmail since it has support for Maildir and it has pop3 capability. Courier-imap is the one I'll be using for IMAP. My concern is webmail. Can anyone suggest a webmail that will run using Maildir format and has addressbook and calendar feature. I'll be using a single server only. Please exclude Squirrelmail from the list.

Can this be done? A company is currently running a postfix mail server. They got a new server and, while the users are migrated, they need to have the messages delivered on BOTH servers.
I thought it could be easily done in postfix: deliver locally AND forward mail to new server, but all solutions I found would deliver the messages in just ONE place.

I am trying to connect a RAID Box to the server via LSI 8880EM2 RAID controller.The raid box is FUjitsu Externus DX60 with raid 1 configured.The server is Fujitsu Primergy SX300 S5 with LSI 8880EM2 RAID card.The external raid box is being recognised by the raid controllers bios.
The server runs CentOS 5.5 64bit. I have installed the megaraid_sas driver from LSI website and MegaCLI utility but CentOS still fails to see the box.MegaCLI utility, when launched from CentOS, recognises the raid box, CentOS does not(no mapping being created in /dev).
I have also tried to create a logical RAID0 HDD on one physical HDD(as seen by MegaCLI) with MegaCLI utility in CentOS.The result was success and the new logical drive could have been used, but when restarting the server, the controllers' bios fails with an error (not surprised(one logical RAID0 on one physical HDD)) and configuration is being erased.
Has anyone tried connecting 8880EM2 controller to a raid box with raid configured on the box, running it all under CentOS and what were the results.
