I recently purchased 3 new WD cavier green 500gb drives with the intent of building a raid5 array and running linux. Admittedly I purchased without doing enough research and now I have serious doubts about running an os on raid5 with the onboard controller.So now I am thinking I should run one drive as an OS drive and mirror the other two. I don't have a fourth drive unless someone can convince my wife I need a fourth after already buying 3....
Is it possible to have multiple distributions where ALL distros save their docs to the raid dives? That way I can wipe/install the os and keep my files? I seem to recall that I can be done, just need someone to point the compass.
I have a SATA drive that worked fine. Then I installed two more hard drives into my system. When these hard drives are installed, if I try to access the SATA drive in Linux, it will start lightly clicking and then the drive will become unavailable. If I power on the machine without the other two hard drives then it works fine. What could be causing this to happen? I don't think it's heat because the two hard drives are far away from the SATA drive.
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 have approx. 30x Western Digital SATA 2.5" hard drives ranging from 80GB to 500GB. These are ex-Tandberg RDX QuikStor backup drives that I no longer use and would like to use them as spare laptop hard drives.The only problem is upon installing the drive in a laptop it prompts for a hard drive user password.
Are there any open source methods to wipe the password (and data; I don't care about that)? I've tried using various wiping methods (dd, dban etc.) but the password still remains.Any help is greatly appreciated; I really need these drives.Plugging it in via a USB HDD enclosure shows as /dev/sdb but does not respond to (c)fdisk or show any partitions (/dev/sdb1 etc).
When the computer starts, you will read a flashing message about S.M.A.R.T and a few other things.I have two hard drives. There is a strange noise from the computer when I run it for more than 3 or 4 hours continuously. I firmly believe one of the hard drives is not working properly. I saw a message about a problem in S.M.A.R.T.It was a flashing message. I couldn't read it. I don't run any Windows on the computer. All are Linux. The default is Mandriva.
How do I read the flashing message you see at the start of a computer? I want to find out the damage one replace it with a new one.
I was thinking about this for a while and I haven't come across it in any of my reading. Could you split an os over two drives? Example: drive hda, 35GB xp - 5GB fat32storage / hda1 8GB root - 2GB swap drive hdb 10GB usr - 10GB home -10GB var / hdb 10GB root linux#2 hdb 1GB swap - 9GB user - 5GB home - 5GB tmp I hope I made this clear enough I'm sure someone must have tried this before. Maybe I got too much time on my hands.
I have Fedora 14 installed on my main internal drive. I have one Fedora 14 and one Fedora 15 installed on two separate USB drives.When I boot into any of these drives, I can't access any of the other hard drives from the other drivesll I can, but just the boot partitions.Is there any way of mounting the other partitions so I can access the information?---------- Post added at 12:42 PM ---------- Previous post was at 09:34 AM ----------I guess even an explanation on why I can't view them would be good too.
I'm trying to setup a dual boot system with Windows Vista 64 (already installed) and Ubuntu 10.10. I added a new drive which is identical to the one Vista is installed on. When I boot into the LiveCD I can see and mount the second drive and edit it in Gparted. However, when I use the installer it will only bring up the drive that already has Vista installed.
I have 2 hard drives and when I do an auto install.. Ubuntu decides to take both hard drives... how do I prevent this from happening without my intervention?
I have a 3 year old PC with 4 internal SATA ports. My old SATA hard drives, all smaller than 2TB, work fine. If I buy a 3TB SATA hard drive, will it work in Linux? Will Linux with GRUB be able boot from such a hard drive without a BIOS upgrade? With a BIOS upgrade? It's fine for me to upgrade my Linux to the newest kernel.
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
I have a FAT32 external USB hard drive with a bunch of stuff I want to copy onto a RHEL server. Is it as simple as it is on a Mac or PC where I just plug it in and it will show up, then I can copy all the files off of it?If it is, how do I safely remove the drive after I'm done with it?
I have one machine with two disks that I'd like to install Slackware on. I'd like to have the root folder and installed folders on hdb, and just have have hda as a disk I can use for storage (without any home directories, etc.). My problem is, I don't know how to make this boot, as I think LILO is installed on the primary drive, but the boot folder is located on hdb. I tried doing this before and was having problems booting, so I was just going to go through the whole process again, but don't really know the correct procedures.
I'm not a stranger to Ubuntu Linux and I was using it for a couple of months with no problems until last week when I turned my computer on and it would go no further than the boot screen and it said 'Error- Insert System Disk'. So I inserted the system disk (Ubuntu Linux 10.something) and after waiting 10 minutes for it to load up it said 'Installation failed, desktop session will now be run and you can try installing again'. So I tried installing whilst on a desktop session and I eventually got to step 4 of 8 and it lets me go no further. This is what step 4 of 8 is:http://oi54.tinypic.com/mx2g79.jpg
And so I cant choose any disks or partitions and so it wont let me go any further. How do I create one? I'm currently running on desktop sessions and they take forever to load up and I cant watch videos or anything because there is no flash. By the way please try and explain to me really simply because I am quite dopey and I wont be able to understand posh complicated computer words.
I'm not exactly a newbie to Linux and it's OS, I have been using Ubuntu since the 8.xx release. I have two hard drives in my system, Hard Drive #1 is the primary drive and is 250GB, this hard drive is only used for Windows 7 Pro 64bit. The second hard drive is 320GB and split into two partitions. The first half has Windows XP Pro on it and the second partition has Ubuntu 10.04 on it. Both are split evenly at 160GB each. Here's how I did it, I first started by loading Windows XP Pro onto second hard drive, using the entire drive, once all updates and settings were applied I then installed Windows 7 Pro 64bit onto the first hard drive and used it fully. Once all settings and updates were applied I restarted the computer and it loaded directly into Win7, which is to be expected. I opened my computer, browsed through the second drive to make sure all files were intact.
I then downloaded and created a USB installation drive for Ubuntu 10.04. After the creation of the USB drive I proceeded to install Ubuntu 10.04 on my second drive, using half the space for Windows XP Pro, and half the space for Ubuntu 10.04. After that was all setup and done, I restarted one last time. Low and behold Ubuntu 10.04 and Windows 7 both appear on the boot menu, however Windows XP Pro does not. I panicked for a few short seconds but after logging into Windows 7 I realized all my XP Pro files where safe. So now I have 2 hard drives with 3 operating systems. Hard drive one has Windows 7 only and hard drive 2 is split between XP Pro and Ubuntu. However I cannot get Windows XP Pro added to the boot menu no matter how hard I try. I'm not entirely confident using the terminal as I am just starting to learn programming, but I know how to enter the commands and get things moving.
Every website that I look at tells me I need to start by editing some grub/menu.lsd, which for some reason does not exist or is "invalid directory". Some websites say I need to run "sudo apt-get grub-update", which again is an invalid command. Here's what I need. A step by step tutorial on how to add my XP into the loading menu. Example of step by step includes "Step 1: Open Terminal" and etc... It needs to be basic and down to earth. Don't just tell me to run codes and type a bunch of junk because that doesn't seem to work for me. I do not know what (hd,0) or (hd,1) means, but assuming the websites are correct, (hd,0) would be my Windows 7 HD and (hd,1) would be my Windows XP/Ubuntu HD?
I'm working on creating a bootable Linux CD to distribute a sandbox environment to customers that will work on multiple PCs.One requirement of this environment is that we do not want the user to have any access to the underlying hard drives in the computer to prevent any accidental and/or malicious damage. I can prevent the disks from automounting with a few udev custom rules, but is there any way to prevent/block the user from manually mounting the hard drives after boot up.
I've been through a lot of the posts already, but nothing seems to solve my problem. I have Ubuntu 9.10 and Windows 7 dual installed (Windows was installed first). Everything has been working fine until a few weeks ago when I accidentally left a USB drive plugged in when I restarted my computer from Windows.
Ever since then, whenever I have restarted my computer from Windows grub2 has failed (it does not fail when I restart from Ubuntu). I get a varying message like Grub loading. The symbol ' ' not found. Aborted. Press any key..where the part between the single quotes is usually different each time. When this happens I have to reinstall Grub2 from a live disk, which is becoming a bit of a pain.
I've been reading around, but I don't really have a great understanding yet of how hard drives and partitions work in general, and so I haven't been able to work out what the source of this problem is.
I just started working with Linux over the weekend. I do have a working dual booting system but it's not configured exactly how I want it to be. Currently Windows 7 Ultimate and Ubuntu are on the same hard drive but different partitions. The Windows boot screen comes up and I can select Windows or Ubuntu fine. Grub comes up when I select Ubuntu and I can successfully select any choice in the menu and it will run properly.
Everything works great now so you may wonder why I even want to keep tinkering, well, it's not working how I want it to. This is what I want it to do. I want Windows 7 on disk 0 and Ubuntu on disk 1. I want each OS to have it's own hard drive. I want Grub to be the only boot loader that comes up with the option to select Ubuntu or Windows. I want to skip the window's OS selection screen all together. I can modify Grub, I've already done some of that on my work computer.
I've been installing from windows. Should I use a CD instead? Would that accomplish my goals without doing anything special?
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 recently finished installing Fedora 9 on a Prolient ML 330 G6 Server, but i configured the SATA hard drives to be viewed as four seperate hard drives. I was asked to merge the drives to be seen as one 800GB hard drive, my biggest fear is that we had set up Samba to share folders between fedora 9 giving specific users access to specific files saved on the Prolient server, will those settings be lost.And could you call that a File Server or do you have to enter any more settings And also if anyone could point me to a tutorial on Logical Volume Management and Raid specifically for fedora 9
I recently aquired server with TWO hard drives.For reason unknown (hehe) i installed unbuntu server on both hard drives.This is causeing me some problems, and i would like to wipe everything and start over, would like to put unbuntu server on one hard drive and use the other for free space.P.S I have had Unbuntu server run succsessfully i am just unclear on how to clear a hard drive of any OS.Oh did i mention the first time i used linux was 3 days ago? Ye i am a newby (sigh)
I am using Dell Inspirion 1545 core 2 duo T6600, 3 gb ram,320 gb sata hddand in my bios i got 4 option (1) disable which disable sata and hdd is not detected (2) ATA where in my M$ is working(3) AHCI which mode will work. also i am using vm-ware to installed redhat linux 5.my hdd did not detected. do u need any information tell me i will post it on the same any command out put or log by which we can solve this problem.
I have a Centos 5.5 system with 2* 250 gig sata physical drives, sda and sdb. Each drive has a linux raid boot partition and a Linux raid LVM partition. Both pairs of partitions are set up with raid 1 mirroring. I want to add more data capacity - and I propose to add a second pair of physical drives - this time 1.5 terabyte drives presumably sdc and sdd. I assume I can just plug in the new hardware - reboot the system and set up the new partitions, raid arrays and LVMs on the live system. My first question:
1) Is there any danger - that adding these drives to arbitrary sata ports on the motherboard will cause the re-enumeration of the "sdx" series in such a way that the system will get confused about where to find the existing raid components and/or the boot or root file-systems? If anyone can point me to a tutorial on how the enumeration of the "sdx" sequence works and how the system finds the raid arrays and root file-system at boot time
2) I intend to use the majority of the new raid array as an LVM "Data Volume" to isolate "data" from "system" files for backup and maintenance purposes. Is there any merit in creating "alternate" boot partitions and "alternate" root file-systems on the new drives so that the system can be backed up there periodically? The intent here is to boot from the newer partition in the event of a corruption or other failure of the current boot or root file-system. If this is a good idea - how would the system know where to find the root file-system if the original one gets corrupted. i.e. At boot time - how does the system know what root file-system to use and where to find it?
3) If I create new LVM /raid partitions on the new drives - should the new LVM be part of the same "volgroup" - or would it be better to make it a separate "volgroup"? What are the issues to consider in making that decision?
I have a few hard drives that I connect to my system with an usb to ide cord. some of the drives mount right away but some others don't below example.
