Ubuntu Installation :: RAID / LVM Cmds To Migrate To Larger Drives?
Sep 27, 2010
how to migrate my whole server to larger hard drives (i.e. I'd like to replace my four 1TB's with four 2TB's, for a new total of 4TB instead of 2TB)... I'll post the output from everything (relevant) that I can think of in code tags below.
I'd like to end up with much larger /home and /public partitions. When I first set up raid and then LVM it seemed like it wouldn't be too hard once this day arrived, but I've had little luck finding help online for upgrades and resizing versus simply rebuilding from a failure. Specifically, I figure I have to mirror the data over to the new drives one at a time, but I can't figure out how to build the raid partitions on the new disks in order to have more space (yet mirror with the old drive that has a smaller partition)... don't the raid partitions have to be the same size to mirror?
Ubuntu Server (karmic) 2.6.31-22-server #65-Ubuntu SMP; fully updated
Code:
cat /proc/mdstat
Personalities : [linear] [multipath] [raid0] [raid1] [raid6] [raid5] [raid4] [raid10]
md5 : active raid1 sdd5[1] sdc5[0]

I have a RAID 6 built on 6x 250GB HDDs w/EXT4. I will be upgrading the RAID to 4 2TB HDDs.
How would one go about this? What commands would need to be ran? I'm thinking about replacing the drives 1 at a time and letting it do the rebuild, but I know that would take a lot of time (which is fine). I don't have enough SATA ports to setup the new RAID and copy things over.

I currently use Xubuntu on a dual boot system, a laptop. The hard drive is to small (30 GB shared between Xubuntu and windows), so I want to clone the existing drive, but I do not want to clone windows.
I bought a 120 GB hard drive, and want to dump windows totally. If I download clonezilla and burn it to a cd, can I instruct it to only clone the Xubuntu system? I think I would run clonezilla from a cd, download everything to my USB drive, then remove the small hard drive. Then, install the bigger drive and restore everything to the newer and larger drive. Will this work??

I had done a new lucid install to a 1 TB RAID 1 array using the alternate CD a few weeks back. I messed up that system trying to some hardware working that lucid doesn't have drivers for yet, so I gave up on it and reinstalled to a single 80 GB disk that I now want to move over to the RAID array.
I moved all of the existing files on the array to a single folder, then copied all of the folders from the 80 GB disk over to the array with permissions and symlinks (minus the contents of /proc and /sys, which I created empty).
These are the commands I used:
Quote:
p -a -d -R -v -t /media/raid_array /b*
cp -a -d -R -v -t /media/raid_array /d*
cp -a -d -R -v -t /media/raid_array /e*
cp -a -d -R -v -t /media/raid_array /h*
[Code]....
I tried to change fstab to use the 689a... for root, but when I try to boot, it's still trying to open /dev/disk/by-uuid/412d...
So then I booted from the single disk again and chrooted into the array, then ran update-initramfs -u. I got 3 "grep: /proc/modules: No such file or directory" errors, and "cat: /proc/cmdline: No such file or directory"- so I created directory /proc/modules, created an empty file /proc/cmdline, and ran the initramfs update again. Then I tried to shut down, which hung (probably because I was doing all of this from a terminal window in Gnome), so I killed the power after a couple of minutes.
It's still trying to use /dev/disk/by-uuid/412d... to boot.
What am I missing? I assume I just have to change the UUID to mount as root, but I don't know how.

I'm working on a server and noticed that the to RAID5 setup is showing 4 Raid devices but only 3 Total devices. It's on a fully updated CentOS 5 system that only has three SATA drives, as it can not hold anymore. I've done some researching but am unable to remove the fourth device, which is listed as removed. The full output of `mdadm -D /dev/md2` can be see below. I've never run into this situation before.Anyone have any pointers on how I can reduced the Raid Devices from 4 to 3? I have tried
mdadm /dev/md2 -r failed
mdadm /dev/md2 -r detached
but neither work and since there is no block device listed I'm not quite sure how to get things back in sync so it's only seeing the three drives.
/dev/md2:
Version : 0.90

Raid Level : raid5

I have a CentOS 5 based Linux system with a 3Ware 9550SU RAID card and four 500GB drives set up in a RAID5 array (3 in the array and 1 hot spare).
I want to 'replace' these drives with four 2TB drives without data loss. My server case has a total of 8 drive bays all hot-swap and all attached to the RAID card, this means I have four empty drive bays on the RAID card.
One thought is to put the four new 2TB drives in the empty drive bays, configure them in a new RAID5 array. Then the question is now to I "mirror" the original RAID5 array over to the new one?
This is just a thought though, I am not sure it will work. In short my question to this forum is how do I accomplish this upgrade?.

I was recently given two hard drives that were used as a raid (maybe fakeraid) pair in a windows XP system. My plan was to split them up and install one as a second HD in my desktop, and load 9.10 x64 on it, and use the other for mythbuntu 9.10. As has been noted elsewhere, the drives aren't recognized by the 9.10 installer, but removing dmraid gets around this, and installation of both ubuntu and mythbuntu went fine. On both systems after installation however, the systems broke during update, giving an "read-only file system" error and no longer booting.
Running fsck from the live cd gives the error:
fsck: fsck.isw_raid_member: not found
fsck: Error 2 while executing fsck.isw_raid_member for /dev/sdb
and running fsck from 9.04 installed on the other hard drive gives an error like:
The superblock could not be read or does not describe a correct ext2
filesystem. If the device is valid and it really contains an ext2
filesystem (and not swap or ufs or something else), then the superblock
is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
In both cases I setup the drives with the ext4 filesystem. There's probably more that I'm forgetting... it seems likely to me that this problem is due to some lingering issue with the RAID setup they were in. I doubt its a hardware issue since I get the same problem with the different drives in different boxes.

I have recently installed a Asus M4A77TD Pro system board which supports raid.
I have 2 x 320gb sata drives I would like to setup raid-1 on. so far i have configured the bios to raid-1 for drives, but when installing Ubuntu 10.04 from the cd it detects the raid configuration but fails to format.
When I re-set all bios settings to standard sata drives ubuntu installs and works as normal but i have just 2 x drives without any raid options. I had this working in my previous setup but thats because i had the o/s on a sepreate drive from the raid and was able to do this within Ubuntu.

I have a machine running 11.3 and I want to increase my storage capacity but am maxed out with 6 SATA hard drives already. Does openSUSE 11.3 see and write to drives 1 terabyte and above correctly?
I have been using WD Green drives in this machine up until now but see Samsung and Hatachi drives at really good prices. Are these drives reliable? How is warranty support?

I'm breaking into the OS drive side with RAID-1 now. I have my server set up with a pair of 80 GB drives, mirrored (RAID-1) and have been testing the fail-over and rebuild process. Works great physically failing out either drive. Great! My next quest is setting up a backup procedure for the OS drives, and I want to know how others are doing this.
Here's what I was thinking, and I'd love some feedback: Fail one of the disks out of the RAID-1, then image it to a file, saved on an external disk, using the dd command (if memory serves, it would be something like "sudo dd if=/dev/sda of=backupfilename.img") Then, re-add the failed disk back into the array. In the event I needed to roll back to one of those snapshots, I would just use the "dd" command to dump the image back on to an appropriate hard disk, boot to it, and rebuild the RAID-1 from that.
Does that sound like a good practice, or is there a better way? A couple notes: I do not have the luxury of a stack of extra disks, so I cannot just do the standard mirror breaks and keep the disks on-hand, and using something like a tape drive is also not an option.

My two 400G drives which have been added to a single 800G array (per fastbuild bios utility) still show up as two 400G drives in fdisk. Why is that?

So windows wouldn't recognize my drives as a raid setup, so I disabled it and switched to IDE, now Ubuntu 9.10 installation will only recognize my drives as RAID. I have and ASUS M3A32-MVP Deluxe Series motherboard, it has 4 sata connectors and 2 marvel controlled sata connectors. In the 4 sata connectors I have my 2 wd 500gb hds, my dvd burner, and my external usb, esata slots. In the marvel controlled sata connector I have a wd 160gb hd. Originally when I built the computer I wanted a raid setup with the 2 500 gb hds.
But windows wouldn't recognize the raid set-up and wouldn't boot properly. So I said screw it and removed the raid and set all the drives to IDE. Then, when I tried to install Ubuntu 9.04 it would only recognize my 2 500 gb hds as raid. Gparted recognizes the drives as both raid and IDE. Eventually, after a day or two of praying and messing around the installer recognized both drives as raid and IDE. A couple months later here I am trying to install Ultimate Edition 1.4.

I had hard drive = 2 partition, 1 being extended. I had two ubuntu instances+swap+fat on extended and XP on primary. I moved a partition = success. I create a new partition = success. I installed new ubuntu instance -> fail on restart->. I saw sector error on screen on restart. So, Grub has lost 1 existing ubuntu instance and could not create new entry for new ubuntu instance. Read on forum just boot from Live CD and execute some grub cmds from terminal?

I can find many articles in google about migration from RAID 1 to RAID 5. But what about RAID 5 to RAID 1. I have a root(/) partition in RAID 1 and want to migrate to RAID 1. This is in production systems.

I just installed Debian 5.0.4 successfully. I want to use the PC as a File Server with two Drives configured as a RAID 1 device. Everything with the RAID device works fine, the only question I have belogs to the GRUB 0.97 Booloader. I would like to be able to boot my Server even if one of the disks fail or the filesystem containing the OS becomes corrupt, so I configured only the data partitions to be a RAID 1 device, so on the second disk should be a copy of the last stable installation, similar to this guide:[URL]...

My System Intel Core Duo E5300 Mobo - Gigabyte G31M-ES2L 1GB DDR2 800MHz RAM 4 x WD20EARS HDD I have been trying to install Fedora or Ubuntu for over a week. I thought it would take an hour and i would be away. I have been trying to install using the mdadm Software RAID feature. Everytime it takes about a day to format the drives and then i get an installation error. The drives state they are ready to use as is on any operating system other then WinXP, but this does not appear to be the case.
I am very new to Fedora... I have been doing some reading.[URL].. That information has been promising. I have been able to get into Fdisk off the live CD but i can't figure out how or if it is possible to do what i want it to.
Has anyone had any luck getting these drives to function correctly in a software RAID? I have had good luck with WD drives in the past and just assumed these drives would do what i wanted to but alas i have been proven wrong.
The partitions i wanted was...
- A 2GB swap parition
- A 10 GB RAID 1 partition for Fedora
- The remaining space as a Raid 5 for files.
Am i just banging my head against a wall here, or is this possible.

Using Samba I have looked into the file that stores all my web sites, there were a few strange files that get larger and larger all the time. File names are _Za01716 and _Za01820, they are nearly 50mb in size now. I know these are not Log files so what are they and can I delete them?

I have been battering with FC10 and software RAID for a while now, and hopefully I will have a full working system soon. Basically, I tried using the F10 live CD to setup Software RAID 1 between 1 hard drives for redundancy (I know its not hardware raid but budget is tight) with the following table;
[Code]....
I set these up by using the RAID button on the partition section of the install except swap, which I set-up using the New partition button, created 1 swap partition on each hard drive that didn't take part in RAID. Almost every time I tried to do this install, it halted due to an error with one of the raid partitions and exited the installer. I actually managed it once, in about...ooo 10-15 times of trying but I broke it. After getting very frustrated I decided to build it using just 3 partitions
[Code]....
I left the rest un-touched. This worked fine after completing the install and setting up grub, reboot in to the install. I then installed gparted and cut the drive up further to finish my table on both hard drives. I then used mdadm --create...etc to create my RAID partitions. So I now have

Fedora is having trouble identifying a raid partition, it sees them as separate drives. I got drivers from dell, but during a Fedora dvd install, it mentions nothing about a place to install extra drivers.
When it says it must "initialize" the drives, Fedora then breaks the dell bios raid. How to either install the dell drivers or make Fedora see the raid partition as one?

I'm about to install Ubuntu on two 250-gigabyte hard drives in a RAID 1 array, but I'm confused about how to partition my hard drives. How much space should I give to each partition? How many partitions should I create and where should I mount them? (I should mention that Ubuntu will be the only OS on this array.)

I have two drive on my Ubuntu server. I have a 40GB IDE 5400RPM and an 80GB SATA 7200RPM.
Is it at all possible to RAID 0 the two of these drive? I know it's pretty unorthodox, but it's what I've got without having to buy anything.
If so, what are the limits, cons, and/or potential pros of doing a RAID of these two?

I want to make a RAID5 array with 4 2TB hard drives. One of the drives is full of data so I will need to start with a 3 disks and then once I copy the data from the 4th onto the array, I will then add the 4th drive. This will be my first experience with RAID. I've spent a few hours searching for info but most of what I have found is a bit over my head.

I've got a 10.10 installation, which I am using as a media/download server. Currently everything is stored on a 1TB USB drive.With the costs of disks falling, and the hassle of trying to back 1TB up to DVD (no, it's not going to happen) I was wondering if there's some linux/Ubuntu utility, which can use multiple disks to provide failover/resilience ... Could I just buy another 1TB drive, and have it "shadowing" the main, so that if one goes, I buy another, and then restore from the copy ?
