how to set up a boot partition on the first hard drive separate from two RAID 5 configurations on a Supermicro server with 1-750GB hard drive for the boot partition, and 15-1TB hard drives for data. The 15 hard drives are split into two RAID 5 configurations (7 -TB drives and 8 1-TB drives). I will be installing CentOS 5.2, and the 15 Terabytes of data will store data, and the 750GB hard drive(on port 0) will only have the 100MB boot file. I am using 3ware BIOS Manager to configure the first array of 7 hard drives, and the second array of 8 hard drives (1 drive with boot information will not be included in the array).
to recap, picture this: I want to load CentOS on this server. /dev/sda1 (on the bottom left drive) needs to house the boot partition set for 100MB. The remaining 7 drives (the left half, not counting the boot drive) need to be set up as a RAID 5 array. The eight drives on the right (right half) also need to be setup as a RAID 5 array. After I configure this in BIOS, I run the CentOS setup disk in graphical mode. I get to the portion after the Language and keyboard setup where it says "Installation requires partitioning of your hard drive. By default, a partitoning layout is chosen which is reasonable for most users. You can either choose to use this or create your own. Select the drive(s) to use for this installation". The drives listed are:
When I choose "Remove Linux partitions on the selected drives and create default layout." or any other option, I get different errors. I notice when configuring via text mode I get better options to install. I can't install the boot drive separate from the two RAID configurations?
I 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.)
I am running the latest suse release downloaded directly from their website. I ran the installation after buring the dvd and everything seemed to be working fine. after the installation i ran updates and used it for a little bit. When i shut it down that night and went to restart it I got an error that stated the OS wasnt there. I then went through the installation and everything and it retained the information from the installation before (web history etc.) but for some reason every time I reboot or shut it down the system is not able to read the startup information from the hard drive and will not come on without me re installing it.
I had a little mission this week-end = my girlfriends 250Gb SATA hard drive laptop crashed this week (video card failure), and I wanted to help her by getting all her valuable data on an old Pachard Bell EasyNote laptop I have hanging around.One big problem : this laptop does not boot on CD drive, nor USB drive, and does not have a Floppy slot. There is an old hard drive with a lot of bad sectors in it, and I have a 80Gb IDE drive I want to put in.
My tools : a SATA to USB adapter, a IDE to USB adapter, a Ubuntu 9.10 LiveCD, a Windows7-run netbook, and the web.My goal : to configure the hard drive in some sort for it to install Ubuntu on boot (much like when you buy a laptop : the OS installs on first boot).I quickly found this to be impossible, as there is no Ubuntu pre-install format available (or that I found). So the next step was to get a complete install on the new hard drive, one way or another.First I tried cloning the 250SATA drive on the 80GB IDE drive, but this clearly led to an error (Grub error 18. It was looking for a 250Gb drive where I only fed him 80.)
Next step was to get some kind of LiveCD-like boot from the hard drive. This is made possible by using the UNetBootIn tool and the related Ubuntu Documentation. I met some problems during the real Ubuntu Install at the point where the laptop tried to format the drive the CD image was on. This other Ubuntu Guide gives a few workarounds and tweaks for that situation, but they didn't solve the issue for me.Final idea was to Live-CD like boot from the rubbish hard drive and install the system on the new hard drive plugged in through USB. This failed because the computer does not boot LiveCD-like on the old hard drive...
I'm kinda stuck on what to do now. I still don't have a nice boot on the computer (only a Live-CD like obtained with the UNetBootIn tool), and am still not capable of doing a "real" install on the Laptop.I'm aware that solving the boot-from-cd issue would bring me a faster solution (maybe!), but the idea was to get a hang on this so that I can install Ubuntu on my CD-free netbook soon (Although my netbook might very well boot on USB, but still).My final and last idea is to go buy some kind of adapter that would let me plug the two hard drives into the laptop at the same time, LiveCD-like boot on the new one, install Ubuntu on the old one (connected directly via IDE) and then clone the old one to the new one. But I wish I don't have to go to that extreme ;o)Writing this I just thought of one thing : I could install Live-CD like Ubuntu on a flash drive, launch it on my netbook and install Ubuntu on the new hard drive connected through USB... Would that work?
After keeping my old (laptop) computer going for 8 years, I've finally taken the splash and ordered myself a new PC, well the compoents any way to build myself a desktop this time.
I've just got a couple of questions.
I've got a 60GB SDD and a 1TB HDD. On the SDD I was planning on partitions for Ubuntu Swap Window partition, to run a Virtulisation, not dual boot.
Performance wise, is it best to install / on the SDD and /home on the HDD or /home on the SDD as well and just move music and videos ect to the HDD.
Just to complicate things, when ordering the HDD there was an offer to get a second 1TB HDD for an extra 11, so now I have 2. I was planning to set these up as RAID 1, which I believe I can do via the alternative install.
What would be the best way to then backup / . I guess it must be possible to schedule an image of/ to be copied across to HDD is it?
I did hear that RAID was a bit iffy in ubuntu, but looking about on the net things seem to be better 9.10 → Also the boot disk isn't RAID.
Are there any RAID or SSD issues I should be aware of?
In my system i have 3 250 GB Hard drives in a RAID 5 configuration. unfortunately, i cannot see this volume in "Computer", so i am unable to access any of the files on the volume. wierd thing is that when i enter disk utility, it finds the drives, and recognises them as a RAID volume. any ideas on how i can access the files on this drive
I am on Ubuntu 10.10.I installed it on a 500 gig hard drive.In the future i want to software RAID(I did it in the past using the alternate version of ubuntu from the installation process), is it possible to add the new hard drive later and RAID later or i need to reformat?I am talking about software RAID.
Every time I reboot my server, one of my hard drives drops out of the RAID5 array. I'm pretty sure that there's nothing wrong with the drive itself. I bought all three drives at the same time, and they are identical in make/model/capacity. While the server is running, it's smooth sailing. However, whenever I shut down or reboot, I get an email message that the array is degraded. It's always /dev/sda1 that drops out of the array. I can always rebuild the array by adding the partition back in, but it's a bit of a pain. Any suggestions on how to troubleshoot this?
I would like to setup a CentOS file server with LVM and Raid1. Having 6 x 500GB drives, 4 x 1GB Ram and a Quad Core Cpu, I am considering to configure 3 hdd as LVM then raid 1 to the remaining 3 hdd's.
i have harddrive on which raid 5 is configure and no file system is configured.so i want to access the data on auto raid component harddisk.could any one telme how to access auto raid component hard drive.when im connectingto my laptop its not opening.when i check in disk analyzer its showing auto raid component harddrive.please helpme to access data inside the raid drive.
I wanted to implement raid5 such that one partition is from my laptop's hard disk and others from other hard disks. After making one partition a raid partition, I rebooted the system. The computer stopped mid-way during booting, and brought me to the shell. On typing fsck -p, it told me an unexpected error occured in the partition which I had made for raid. Is there some condition that we cannot boot from a disk containing one of the raid partitions ?
I have minor problem with upgrading a hard drive. I am running an old pentium lll with two hard drives. On the first hard drive I have two partitions of around 90GB each. On the first partition is installed winXP and on the second partition I have Suse 10.3, both booted by grub and living happily side by side. My second hard drive (which is formatted for windows is only 4GB.
My problem arises when I try to replace the 4GB with a 80Gb hard drive. When I disconnect the 4GB drive the system fails to boot up and complains with error 21.
I'm a bit of a Linux newbie, but I did manage to set up the following RAID-5 system:1x 500GB system drive on ATA IDE4x 1TB SATA drives in software RAIDLinux = Fedora 13So here's what happened. I set up the system to send me an email every time the mdadm stat file changed, so it would send me emails when in periodically ran a self-test. I was away and noticed that the self-test was going incredibly slow (usually took 8 hours...was on course for taking 250 days!) A colleague decided to just reboot the system.Afterwards, the system would not boot and, while all 5 drives were connected, would stop at an endlessly scrolling error message of: Code: ata4.01: exception Emask 0x0 SErr 0x0 action 0x0
ata4.01: BMDMA stay 0x64 ata4.01: failed command: READ DMA ata4.01: (a bunch of hex numbers)
Am trying to install Ubuntu 9.1 on hard drive 2 rather than hard drive 1(7 year old XP machine with 74 GB drive 1) Hard drive 2 is a Firewire-connected External Western Digital.)
with only a 41 MB partition avaialble for Linux).
After install finsishes the boot process fails with:
Restored the MBR from a Windows CD, and thinking the boot loader needed to be in the MBR area of sdb, installed again with "Install Boot Loader" specified as sdb. Same results.
Restored the MBR and installed again with "Install Boot Loader" specified as hd0. Same results.
Restored the MBR and installed again with /boot allocated on sda2 (the 41 MB partition on the first hard drive). "Install Boot Loader" specified as hd0.
Booted successfully, but when installing updates, there was insufficeient space in the boot partition and could not restart.
Ubuntu 9.1 uses GRUB2 for the first time, so thinking "perhaps there's a glitch", installed Ubuntu 8.04 with the first set of specs described above - except "ext3" instead of "ext4". Got "Error 21" from GRUB which is the same as "no such disk".
I have a Toshiba laptop with BIOS that will not recognize USB as a boot medium (I have purchased two USB 'thumb' drives with Distro's that do boot but the BIOS see them as HDD devices!)I did manage to install and boot a distro from the USB HD but ended up with the USB drive having to be connected' to select any of the OS partions, to boot anything.I do realize that somehow, when installing the new distro on the USB drive, I changed the GRUB configuration to be on the USB drive which obviously I did not want, so can
my last hard drive had bad sectors so we got a new hard drive from newegg. this is a brand. new. hard drive. never been formatted before. so i started with the windows setup disc to get it to partition the drive and give kubuntu (working off 10.04 its ordered from canonical) something to work off. it still didn't work. so i got gparted on here to see if it could - im running off the live cd - do anything with it and i find that kubuntu doesn't even recognize there is a hard drive there. i got into the terminal to check the sudo lshw -C disk thing and it swears 'C' is my cd drive.
My bios is also as high as it can go, they stopped making my board. so. any ideas? i cannot install windows as i have lost the key so getting this installed and fixed has to be done through ubuntu on a live cd.
Below is results from attempt at formatting my hard drive. As you can see a driver is installed, but not working. Perhaps something is missing? Seems a bit odd that a "unable to read" comes back when disk data is reported. The drive just went through a low level format. BTW this is a fiber channel drive. Also on board are 5 scsi drives. Adaptec raid card. Not sure if that would have any relevance, but there you are.
I'm running 64bit Lucid. I've recently had a severe problem with my softraid (5) array, and have had to recreate the array to fix it. However this now means that something is up with GRUB/initramfs, and booting times out while waiting for the root device (md0) to be ready. /boot is on a normal partition, not the raid array itself. A friend of mine has rebuilt my initramfs file with the new UUID, but now I get the message: 'Kernel panic not syncing: VFS: unable to mount root fs on unknown-block (9,0)'.So my question is either how do I sort this error, OR how do I rebuild initramfs/grub in a way that will boot?
I have a pre-existing setup with Windows XP Professional and CentOS5.5 on a dual boot setup with the Linux drive setup as the primary drive hosting the grub menu.
I am replacing these machines with new updated ones and they have windows setup on a RAID0. I think it would be easiest to follow my previous setup and move the RAID to secondary SATA ports and put the linux drive on the primary SATA port, or should I just change the boot order in the BIOS to have the secondary linux drive boot first?
can I move a RAID setup to secondary controller ports without breaking the RAID?
I was copying files from one Western Digital hard drive to another newer one, when I accidentally pulled out the usb cable on the copying drive (WD Elements 2TB).Now I can't mount the drive again. I don't really know what this means. I rebooted the computer, but to no avail.I am running Ubuntu 10.04 on Gnome 2.30.2 Kernel Linux 2.6 32-32 generic.
I want to install Puppy on laptop HD. When I run the Universal Installer and select GParted it brings up the Hard Drive (SDA -ATA Toshiba MK6015MA 5.595 Gib) is on Old Compaq Presario 1200. I'll select that drive and hit ok it just takes me back to the Universal Installer Screen. When I first started the Hard Drive was listed and somehow I must have removed it. Is there another program where I can select the HD and partition it etc.
My portable hard drive (WD My Passport), which used to work correctly now does not automount on my Ubuntu system. It does work on a Windows machine or even when plugged into WD HD TV, which is a Linux based device. There's one NTFS partition spanning the whole drive.When I plug the disk in, I see the following in dmesg:[269259.504631] usb 1-2.2: new high speed USB device using ehci_hcd and address 20[269259.604674] usb 1-2.2: configuration #1 chosen from 1 choiceHowever it does not mount in GNOME and I don't see it when I type:sudo fdisk -lAny suggestions why this might be? I repaired the partition using chkdsk on Windows, so the issue is probably not filesystem related.
I wanted to make a clone of my drive, so I tried the ole sudo dd if=/dev/sda1 of=/dev/sdg1 trick, but first I formatted the drive to the Ext4 format. I wish I would have understood that format a little more before I decided to format it that way. Now I can't access my drive at all. I read almost everything on the net about manually mounting it, but almost everything was in Fat, NTFS, or Ext3/2 format. I even read the Ubuntu documentation. I don't know if it's because my drive is in Ext4 format, or if I'm just not doing something right.
As you can see in the following picture, it recognizes the drive, yet I am unable to mount it. I am trying to access the 160 GB drive. I even tried to see if Windows would recognize it. No go. Today while lurking in the Ubuntu Forums I found a way to make a live .iso of my system (which I think is awesome). So now I want to reformat my drive and use it as storage once again. I think I will restore it to NTFS. I thought that the Ext4 format would work better in Linux (which I was wrong), but now I need Windows to recognize it as well, and it needs to be able to store files bigger than 4 GB (unless you have a suggestion on what to format it as).
