Ubuntu :: Raid Hard Drive Not Showing In Computer?
Jul 21, 2010
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 have a load of partitioned hard drives and even though the are refrenced in fstab I still get Bookmark Icons and they are also visable in 'Computer'How do you remove these icon?I would also like the ones not refrenced in fstab to only be mountable via password - lucid seems to just mount when you click, I did change this as in another post but it also made USB keys need a password
Code: gksu gedit /var/lib/polkit-1/localauthority/10-vendor.d/com.ubuntu.desktop.pkla change the ResultActive=yes to ResultActive=auth_admin_keep
Alright. So recently I've been having computer trouble and need to clean install my OS on my main Hard Drive. That normally wouldn't be a problem but there's some stuff on my main hard drive that I really don't want to part with, SOOO I figured I'd pick up a new HD and OS and move the files I want to keep before clean installing. I have my new HD installed and everything and it even shows up as a option in the boot menu. I'm currently running Ubuntu from a Flash Drive but only my old hard drive will show up. How can I access my other HD?
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?
I just bought a brand new hard drive, installed fedora with no errors. However when I try to click on the hard drive i get this errorunable to mount physical volume, not a mountable file system, ( I only have 1 hard drive and fedora boots up fine so its got to be working)I installed hardware browser and no hard drives come up
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.
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 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.
So I tried to install Ubuntu on my Acer Aspire ASE380 desktop, and I think during the partition portion. I think I messed up the hard drive.
Now my computer won't recognize my hard drive. I've tried using the acer repair disks I made, I tried unplugging and checking all the cords and lines, I tired flashing the BIOS, I've tried using other boot disks like Ultimate boot CD, and Acer support is no help either.
I really don't know what to do now. It shows nothing in the boot setup or the BIOS set up. I've also tired the ALT - F10 for acer computers to enter and repair partition and nothing.
I just want to get this thing up and running. I'm tempted to just buy a new hard drive.
My friend gave me his old computer but he kept the hard drive, I have a computer with a 200 gb hard drive. could I partition the hard drive and have the computer my friend gave me access the other partition without having to take the hard drive out and connect it to the other computer?
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 have 2 computers, one running ubuntu 9.10 Karmic and the other runs Windows 7.
I have several sata hard drives that I keep files on. They are all formatted ext3. I have a blacx sata to usb dock on my ubuntu computer that I use to go through files and back up and such. I have a usb to sata dock on the windows 7 machine.
When I plug in the hard drive Windows says that it has to be formatted and the drive is "raw"
I can check the drive in ubuntu and everything is right
I tried installing ext2fsd and it sees the drive but wont let me select any file type or mount it. I think because its going through the usb port.
So how can I make windows 7 see and be able to access an ext3 formatted drive thats plugged into the usb port?
I have posted in regards to fixing some problems I had after running recoverjpeg, and most are fixed. However, this process (recoverjpeg) continues to find pictures and dump them into my hard drive. I am fighting an uphill battle. Is there a way to stop a program from running continuously? I removed the package, but it continues to find files on my computer and put them into my hard drive, which is a problem.
I got a problem with the motherboard of my computer and now I need to get some files out from the hard drive (an ext3 partition). I can access the files from another computer but because of the permissions of my user it doesn't let me copy the files over to another drive.
my computer was running Kubuntu 8.10 with a Vista dualboot. I also tried attaching the hard drive to another laptop, but because of the video drivers the display doesn't function properly.
I want to make my own raid array, that is essentially identical to one of those commercially available external raid drives.The only thing is, I want to do this by using a dedicated computer as the drive, and connecting it to another computer to use as the server. Is there some way to do this. Maybe make a sata port on the raid computer appear lixe a hard drive to the server. Or use a usb 'crossover' cable to connect the 2.Is this even possible, or should I just use the raid computer as the file server too?
What I want to do is pull data from any of the hard drives attached to my Linux box from my Windows machine. I have been moving small amounts of data from the drives to my OS drive and those parts share easily, but I want to move away from that method to move large amounts of data at the same time.I have tried using Samba as it is used for file sharing between systems and that I have to give my Windows box permission through Samba.
Trick is, I'm not sure where to start, though I have an idea and wanted to know if this is the right track before I start editing my file system.
I have a dell inspiron 9300. I have Ubuntu 10.04 LTS.on't have the root password.Something I'd like to do would be to have two separate ubuntu's on my computer. I'd like to keep this one just as it is but also have another ubuntu-same version- that I can boot up into, and have it default booting up into the old one. How exactly do I do this? I know very little about computers. I barely mastered registration for this site, and copy/paste is a rather new skill for me.
My macbook pro stopped booting yesterday due to some file system corruption in the hard drive. I am able to access this drive through a linux live cd which I am using now but when I go to some folders it says "Could not enter folder /media/Macintosh HD/..." My question is how do I give myself the permissions to be able to access these files and transfer them to a network drive?
I finally got my new internal hdd for my laptop. I plugged it in and installed windows 7 64 bit. Then I partitioned my external hdd (WD mybook 640gb), and installed ubuntu 9.1 on a 200gb partition of it. The problem is that I didn't unplug the internal hdd before I installed ubuntu. Now the computer will not start unless I have the external hard drive plugged in.
So what should I do so that I will be able to go into windows 7 normally if the external hdd is unplugged? I would also like to be able to use ubuntu when I plug in the external hdd. I wouldn't mind having to go to the boot menu and choosing the external hard drive every time I wanted to use ubuntu.
The reason I partitioned the external hard drive was because it has a lot more space than my 250gb internal hdd, and I also wanted to leave space open to use as was intended, to back up stuff.
However, now that I think about it, I wouldn't mind partitioning the internal hdd and just leaving the external blank (which I should have done in the first place).
I have a laptop with two partitions, one with Windows XP and one for storage (formatted in NTFS). I would like to install Ubuntu on the storage partition, but my problem is that I can't boot from CD (or anything else) because my BIOS is password protected. I obviously don't know the password. y question is: If I plug the laptop's hard drive into another computer, install Ubuntu as described above and then reconnect it to my laptop, will it work?
i can only boot to MSDOs with floppy msdos bootup on A:. I want to install ubuntu 10.10 and completely erase HDD but the ubuntu disc won't bootup even when bios is set for cd only. This is older HP pavillion that I have retired but HDD scans out good so I thought i would run Ubuntu only and maybe put MS out of business but not having any luck with install. When booting from HDD error is system 32hal dll is missing or corrupt but HDD C: is 0 anyway. I just want to install so I can play with Ubuntu.
Today, I finished assembling my dream computer. I can boot it into the BIOS, and I checked that everything was working correctly through there. Anyway, I attempted to transfer the hard drive from this computer to that one. This computer is a Dell (blech) Optiplex GX280 with an Intel processor and integrated graphics. The new one has an AMD Phenom II processor with an ATI card and an ASRock motherboard (drastically different machines, I know...) When I try to boot, GRUB gives me an error message that says something like:
Code: blah whatever cannot find /dev/disk/by-uuid/372de761-9577-48be-ba19-c6b2890cb229 Did I do something wrong installing the hard drive? Or is this a problem that is going to happen no matter how hard I try to make it not happen? If the second is true, will it help if I wipe the disk and reinstall Ubuntu on the new computer?
P.S. I know similar threads about transferring hard disks have been posted, but no thread has mentioned this error.
