I have the newest Ubuntu installed on my machine. It currently has a 160GB sata drive. I just bought two shiny new 2TB drives that I want to RAID as 4TB. How do I go about adding these two hard drives even though install is complete? I want the 4TB assigned to my /home directory.
View 4 RepliesI'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.)
View 3 Replies View RelatedI'm fairly new to linux in general, I am making strides, and I decided to buy a 500gb hard drive to run as a slave, for the increasing amount of data I store, and I cant use it. I tried to follow a PsychoCats tutorial, and while it was informative, I either did something wrong, or I didn't understand. With Gparted I managed to format it with Ext4. IT shows up in my diskspace widgit as /dev/sdb1. But states it isn't accessible, and has a total drive space of 0mb. I don't need anything fancy. I just want it to read and write properly.

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.

View 2 Replies View RelatedSo 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.
We have a server with RAID 0 with 4 hard disks on it each 250 GB. Linux kernel must find one hard disk named: /dev/sda with 1TB capacity. right? And also we have 2 partitions on sda: sda1 and sda2. We want to add another partition but we don't have enough space.
Now the problem:
If we add another hard disk and run
Code:
fdisk -l
Will the /dev/sda space incremented automatically so we can add new partitions or we must do something?
I'm renting a dedicated server with a company that claims that the server has 2 hard drives in a software RAID 1 array, but I need to make sure that the server really has the 2 HDD, and the size of the 2nd drive... how to do that ?? system is Centos 5.3
View 1 Replies View RelatedI am currently trying to configure a set of hard drives as a RAID configuration. My system is running with Red Hat Enterprise Linux Client release 5.1 as the base OS. I am booting from CD. I am trying to image a set of drives that have not been imaged before. When the GUI dialog window for disk setup is displayed, it shows a default disk layout including a LVM slice. In the disk layout is a /boot partition already. It is not what I would like so I edit it to be the size for my system and make it the primary partition. I also select it to be a software RAID. I then add three more partitions for my drive 'A' all of type software RAID and NOT primary partitions.
At this point my drives have the correct number of partitions except for showing the LVM slice. I select 'RAID' again, followed by selecting 'Clone a drive to create a RAID device ...' followed by 'OK'. I then get a dialog to select the source and target. i select my drive 'A' to be the source and 'B' to be the target followed by 'OK'. An error dialog is received stating that all the partitions are not of type software RAID. The disk partitions are all type software RAID except the extended LVM slice. I can not get past this point and I am following a procedure written some time ago by a person that is not available.
I know my Linux Servers have RAID but I want to know
1. Can I find RAID level?
2. how to find Disk information...I mean if it's not possible to get RAID Can I get how many hard drives and the real size?
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

View 1 Replies View RelatedI'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.
so I setup a raid ten system and I was wondering what that difference between the active and spare drives is ? if I have 4 active drives then 2 the two stripes are then mirrored right?

I am building a home server that will host a multitude of files; from mp3s to ebooks to FEA software and files. I don't know if RAID is the right thing for me. This server will have all the files that I have accumulated over the years and if the drive fails than I will be S.O.L. I have seen discussions where someone has RAID 1 setup but they don't have their drives internally (to the case), they bought 2 separate external hard drives with eSata to minimize an electrical failure to the drives. (I guess this is a good idea)I have also read about having one drive then using a second to rsync data every week. I planned on purchasing 2 enterprise hard drives of 500 MB to 1 GB but I don't have any experience with how I should handle my data

I've tried Ubuntu with similar results. Older kernels WILL install onto this same MB/PATA controller (Ubuntu 6.06, 2.6.15 and RHEL4) so it seems that something changed in the ATA driver as the kernel has matured and my bios isn't up to snuff for these pickier drivers.
We were trying to install w7 on a reserved partition. W7 did not like the partition (whatever we tried).
Since we had 3 hard-drives, on the allocated drive we deleted all partitions and set the partition table type new to MSDOS (yast etc.....).
W7 installed fine. We did not time it, but it appeared that 11.3 installs faster plus considering 11.3 installs quite a number of applications.
There are plenty of postings re integrating W7 to the Grub-menu.
This system went through several Suse updates, hardware upgrades, basically was all over the place.... we did a "new" install of 11.3 allocating its own hard-drive.
Install......fine, and Grub entered W7 to the menu. Worked ! Mounted the windows partition to /home/yourusername/windows
So, if you really (?) need W7 and have a spare hard-drive, this maybe is a clean solution.
The installation went smoothly however, I have installed SuSE11.4 on my 2nd Hard Drive. Now Grub doesn't work and I want to know where and how to install it.

View 3 Replies View RelatedI burned the live version of OpenSUSE 11.3 (Gnome, 32bit) to a CD to test the compatibility of an HP Pavilion p6510f. Although Xubuntu 10.4 booted up fine, OpenSUSE did not. A message about RAID would appear (too briefly to read) and then the computer would reboot.I checked in the BIOS and found that the SATA drive has 3 modes: IDE, RAID and AHCI. The hard drive was set to RAID.
When I changed the hard drive mode to IDE, I was able to run the OpenSUSE live CD; but the change ruined my Windows installation. Windows doesn't boot under IDE or RAID mode. (I have reset the mode to RAID and am restoring the Windows installation.) Is there an option/argument that I can pass to the kernel so that OpenSUSE will work under RAID mode? (Since Xubuntu 10.4 was able to do it, I'm assuming OpenSUSE should be able to.)
