Red Hat / Fedora :: Grub Sees Only 4 Gig?
Mar 29, 2010
I got a 450 GB hard drive from which fedora boots from.However when i look at grub,grub> geometry(hd0,0) and do the cylinder/head/sector math, it only comes to 4GB instead of 450gig. why it sees only 4G?

I've tried so many things to get it to see Debian. I tried the super grub 2 disc on a CD and on a flash drive via unetbootin. Neither worked successfully like the site showed. I tried chrooting from a Ubuntu Live CD, I did update-grub grub-mkconfig, grub-install to each of my hard drives and even tried upgrade-from-grub-legacy (even though it's already upgraded from grub legacy)!
If I recall correctly, the super grub 2 disc says something about an error with the filesystem so I'm guessing this has to do with the fact that I'm using ext4 on my Debian Squeeze installation?

i recently started dual booting with Kubuntu using an external HDD. GRUB works fine, but it sees two Kubuntu's on the drive. In GRUB, i see "Ubuntu-Linux Kernel (for some reson its not identified as Kubuntu) on /dev/sdb1 (external drive)", then i see recovery mode beneath it, and the exact same line right below recovery mode, followed by another recovery mode. strangely, selecting either one boots into kubuntu no problem at all. is this a problem and is there anyway i can delete the duplicate entries?

After an update a few days ago, my X install believes I only have a Vesa card. I can't get it believe the nvidia drivers are installed. Not sure what info is relevant, so here's a start:-
[root@undertaker ~]# rpm -qa | grep nvidia
xorg-x11-drv-nvidia-195.36.15-1.fc12.x86_64
xorg-x11-drv-nvidia-libs-195.36.15-1.fc12.x86_64

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?

Why does ubuntu only see a single core on my quad-core cpu? All cores are enabled in the bios.
Here are some details about my hardware...

I decided to go and install ubuntu 10.10 today. I have two partitions on my HDD. Ubuntu only sees one HDD, and not the two partitions. I get no option to dual boot vista and ubuntu at all. It is only format and use the entire disk, or install manually. I go into gparted and all ubuntu sees is one unformatted HDD. But vista sees two partitions. I have all of my media on one partition. I REALLY don't want to go and format the entire drive to lose my things. Is there a work around for this? I have no access to any other PC.

I have three computers; Ubuntu desktop, Windows 7 laptop, and OSX laptop 10.5.8. I have a shared usb hard drive on my Ubuntu desktop. My Windows 7 machine sees and accesses it just fine. My OSX computer sees it in the finder window, but says it can't access it because it can't find the original file. I have tried to "repair the alias" but it doesn't work. I have shared another folder on the Ubuntu desktop, but the new share is on the desktop internal hard drive. OSX can access that share with no problems. What in the world is going on? If Windows 7 can see and access, is this an OSX problem or is there a terminal command that I am missing? I am networking using Samba on the Ubuntu computer and the explorer/finder windows on the Windows7/OSX computers.

I thought I knew my way around a little, but apparently mounting is still a complete mystery to me. I'm trying to back up my data with Knoppix since Ubuntu won't start up. something weird is happening with the keyboard and it starts spamming ^[[26~ across the splash screen. When I try to read my hard drive, Knoppix tells me "mount: wrong fstype, bad option, bad superblock." It seems like it should be a pretty common error, but I haven't found any anything helpful and understandable that doesn't involve rebooting (won't get me anywhere with Knoppix). I think it has something to do with Knoppix insisting my drive is hda instead of sda, though I have read that Ubuntu likes to tell you hda is sda anyway. Knoppix is the only distro that has worked on a live boot so far.I've thought of trying dd, dd rescue, or just cp onto my external, but I don't know if Knoppix's hda business will make a working backup. The other computers around are all Windows with no extra space, so I don't know what the easiest and safest way is to test wether the back up worked.

I just set up Suse 11.1 64bit and installed Virtual Box 3.1.6. I had it running previously with no problems, however, this time I can't get it to recognize any USB ports. In fstab I entered the line
None /proc/bus/usb usbfs devgid=1000,devmode=664 0 0
and ran mount -a (no go)
I loaded Vmware Player and it uses the USB ports perfectly fine (go figure) I added to the "none" line auto,
busgid=1000,busmode=0775,devgid= etc.
Still a no go - vmware uses them no matter what I have in "fstab" what am I missing with Vbox?

I recently had to reload CentOS (5.3) on a box because of an unrelated problem (one of its SATA drives went belly up). I decided to update the old (reliability questionable) 80 GB IDE HDs that had been in it with some new 160's while I was changing stuff around.
the BIOS sees both IDE drives, and so does a bootable Acronis CD I have (boots some Windows version). But CentOS refuses to see both the IDE drives (the new SATA drive dropped in w/o difficulty). I spent some time messing with Master/Slave settings and switching disks around--CentOS only sees the Master disk (whichever physical drive that happened to be at the time--clearly was not a bad drive). Here's what dmesg has to say for itself in the relevant section:
Code:
Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
NFORCE-MCP55: IDE controller at PCI slot 0000:00:04.0
NFORCE-MCP55: chipset revision 161
NFORCE-MCP55: not 100% native mode: will probe irqs later
NFORCE-MCP55: BIOS didn't set cable bits correctly. Enabling workaround.
NFORCE-MCP55: 0000:00:04.0 (rev a1) UDMA133 controller
[Code]....
The MB is a Tyan S2912 w/ 2 Dual-core Opterons (with an admittedly older BIOS, but the BIOS sees the drives; and so does the different OS so it seems like it's gotta be something w/ CentOS). The extra space of the 2nd IDE drive was not critical, so I just took it out for the time being (may try a BIOS update later).

I upgraded a DL580 G4 server from Red Hat 4.4 to 5.2 (2.6.18-92.el5 #1 SMP Tue Apr 29 13:16:15 EDT 2008 x86_64 x86_64 x86_64 GNU/Linux) and now when I run the multipath - l command I only see one path. There are 4 LUNs being presented on each fibre channel, so I should see sda - sdh in /dev, but I only see sda - sdd.

Trying to use Yast2, and it gives errors: " can't access installation media [url] " and this is with all the repositories that used to work fine. Not sure what it could be? I tried to use a mirror, and I got the same results.
Does Yast2 use a port other than port 80 to connect to the repositories? I have not updated the firewall since using Yast last. Have the repository servers been updated since the release of 11.3, to make some editing of the repositories in Yast necessary?

I'm getting rather bewildered.
I followed these instructions to setup my wusb11 driver using ndiswrapper:
[URL]
But when I try to ifup the interface, I get:
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 4
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 10
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 14
DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 3
No DHCPOFFERS received.
iwconfig shows that no essid is assigned, even though I have specified one in /etc/interfaces.
Then if I go through the desktop gui Preferences -> Network to setup my wireless connection, /etc/interfaces does not seem to change but iwconfig then reports the essid is assigned.
Anyway, on my default taskbar there is a wireless icon. Clicking on that shows the wireless access points in the area. I see my own. When I try to connect to it, it prompts for my wep key. I enter the key, it thinks, and then acts as if I'd entered the wrong key.
Specifically of course, I'd like this to get fixed so that I can happily surf the net again, etc.
But I also I'm wondering why it seems that there is a disconnect between /etc/interfaces and Preferences->Network. If I type in a WEP key in the gui, I would think that it should appear in /etc/interfaces.
I'm definitely a Ubuntu wireless newbie, and not very experienced at Ubuntu anyway.

I am using Ubuntu 9.1 and want to connect to my other computer (win 7) on my home network. I installed Samba...and it sees the 'windows network'...then it sees the pc I want to connect to, but when I try to dbl click on its name, I get 'unable to mount location, failed to retrieve share list from server'. There are at least 8 publicly shared folders on that PC that other Windows pc's can connect to without problem.

Has just bought an old Teac CD-C68E cd changer for 2$ and I would like to use all the six drives but debian can't see all just the first. After searching I only found a page of a suse article in which a suse package named "cdload" solved the problem. After that I searched the debian repo but they don't have that package. Tried to search globally, yet no luck. I'm not only interested in that package but everything that makes that oldie working. Here's a spec page of that cd-r.

I have just installed Ubuntu 11.04 on a new computer which also has Windows XP installed. This computer is connected to the internet via a USB Zonet ZEW2590 802.11N wireless card with the Ralink RT3070 chipset. Ubuntu sees the wireless card and it connected to my wireless router without any problems. When I look at the connection information it says the wireless card is connected at 24mb/s and one time it said it was connected at 54mb/s. The problem is that when I go into Firefox and type in a url (such as www.yahoo.com) I see a message at the bottom of the screen saying "Looking Up Yahoo and then it does nothing for several minutes. Then I get a pop-up box that says "Server Not Found".

I have 2 Hard drives, the original 30GBs with Windows XP on it, My son put 2nd hard drive into pc as slave (400GB), no problems, WinXP recognised 2nd drive. This was all a way to give 'good ole Mum' a chance to muck about with Linux.Got a Linux Format Mag with Ubuntu 9.10 on it, amongst others, but this one I knew from previous use. I have installed it on the 2nd hard drive, not sure if I correctly (manually) partitioned but I put ( I believe) a home partition, a swap partition, left ( so I thought) a 3rd partition space, and said install. Ubuntu runs fine and see the small HD with WinXP but WinXP doesnt see the HD with Ubuntu, and I wanted to use the 3rd partition for the WinXp as I need to use that for Grant writting I do for not for profit organisations govt depts that I apply for grants from are MS freaks, that said, all runs ok but what have I done that wont let WinXP see to utilise the 3rd partition. Be kind, I have a load of senior moments these days

I was just using Amarok 2-3 days ago and everything was working fine. Now every time I launch Amarok it shows 0 songs in my collection. Under my collection properties, it still shows I have the correct folder selected. When I try to rescan my collection, absolutely nothing happens. Also, when I quit the program, it stays in the top gnome bar. When I click on it, the exit option is gone and I have to manually kill the process.
I'm running 10.04 with the 2.6.34-5 kernel.

Last week when I was still running Lucid I could get Banshee to read and write to my Sansa Clip Plus fine, but now that I have upgraded to Maverick Banshee can no longer see it.
I have it set in MSC mode with an .is_audio_player file (that worked back in Lucid) and Rhythmbox can see it and read and write to it fine. Has anyone else encountered this problem or does anyone else know what might be causing it? Banshee's version is 1.7.6 and the contents of my .is_audio_file are posted below:
Code:
audio_folders=MUSIC/,PODCASTS/,AUDIOBOOKS/
output_formats=application/ogg,audio/mpeg,audio/flac,audio/x-ms-wma,audio/aac,audio/mp4,audio/audible
input_formats=application/ogg,audio/mpeg,audio/flac,audio/x-ms-wma,audio/aac,audio/mp4,audio/audible

I bought a second hard drive, (seagate, 1TB) and followed some instructions about how should i format it. Unfortunately i don't remember where. I ended up with a fully functional disk and copied to it about 400 Gb of data. As far as i knew there was a single 935Gb partition. I needed to shrink the partition to create a smaller one i need in vfat, and every partition manager i tried (gparted, parted, Kde's partition manager, testdisk) sees the disk fine, as a 1TB unallocated space hard drive. I realize, the data was copied directly to /dev/sdb, not /dev/sdb1. I can access the data with no trouble, it gets mounted on boot and on use i have no issue. But i can't edit the partition table, because as far as parted is concerned, it's all unallocated space. I tried running testdisk (even deep) and parted rescue, but they don't see any partitions. Any thoughts? maybe some way of making a new partition table without erasing data=?
