OpenSUSE Install :: Boot-up Results In A Read-only Root Drive?
May 20, 2011
Somehow, the wife got her laptop into this situation yesterday. The Windows partition booted normally when selected from GRUB but os 11.3 would boot to a command line login and pretty much everything besides CTRL-D was useless as the root partition was ro.
I booted a live CD and found two a couple of strange things. First, the system clock was reset to the default date/time (2007-xx-xx). I reset that. Second, after correcting the time I ran fsck on the root and home partitions. Both went through with no errors reported but the 20GB root partition took a long,long time to complete while the 80GB home partition went pretty quickly. After doing the above, the system booted normally but both partitions reported running the transaction log as well as forcing fsck where I had just done that. My question is for future reference: how does the system react to a grossly incorrect date/time, especially where all the drive data reports being much later than the reported system time? Would this be the reason for what I saw? I have no idea how the wife managed to reset the system clock, even if the
One more thing, as you can see I also set that only the owner of the directory (which is me again) can read and cd (the execute bit) to the directory. how come user 'root' can read the content of the file ?
Code:
# id uid=0(root) gid=0(root) groups=0(root) # cat /tmp/testperm/file.txt Hello world
I have a large external drive, which I connect to my laptop via a PCMCIA card - the machine is old and does not have USB 2.0 built in, so I use the PCMCIA card for that.
I am thinking of the following setup, and hope you can give me some tips on whether or not that would be a sound solution:
- designate a boot partition on the laptop's internal hard drive, which could store kernels
- make up a linux partition (or more than one) to use as root for any distribution on the external drive
- keep /home as separate partition on the external drive
My goal in mind is to be able to boot more than one Linux partition from the external drive. I can't make it through USB boot because the PCMCIA card is not recognized before a kernel module is loaded, and I can't use the internal USB 1.1 port for the external drive.
Do you think this is the way to go? Currently, I only have my /home partition mounted off the external drive.
I have multi-version Kernels on a Dual Boot WinXP / openSUSE 11,3 box. It's been a LONG time since I needed to boot to Win XP and now that I find that I can't get to it, I can not say for sure what I did to break it. Looking back, I suspect that the method I used for the recent removal of one of the Kernel versions may have been innappropiate. Rather than unchecking in versions/package groups I may have just removed the unwanted kernel in the package list. Not sure. I've tried dinking around with menu.lst and Yast Boot Loader to no success. I get errors depending on what I messed with. Didn't try to reinstall grub until I checked here for help with a fix.
I tried two times to make an new partition (after the FAT partition on it) on my external hard drive with YaST>Partitioner.Fist I had tried ext3 now I have ext2 on it.Both times the partition (or the corresponding folder in /media) was only writeable to the superuser/root but not to a normal user (readable to the normal user). Root is the owner.The FAT-Partition on the same external drive is owned by the normal user who was logged in as I plugged the USB-cable in.I can unmount both partitions als normal user in natilus.1. Can I start nautilus as root to change the permissions?2. What have I done wrong? Should I use an SuSE Live-CD or an CD with an special partitioning-program instead?ng X20) openSuse 11.1 and Gnome 2.24.1 (mostly, 1 account is using KDE) and Kernel Linux 2.6.27.45-01.1-pae. "/home" is on an separated partition (as part of an extended partition). I have also 2 NTFS partitions for Windows XP (System and Data), and a FAT, a root (/) and a swarp partition.
I'm new to OpenSuse and also fairly new to Linux in general. I installed OpenSuse 11.2 on a secondary machine and I really like it. However, during booting it stops somewhere half way, giving me only a black page but with a functioning cursor arrow. I can't do anything with it though. I re-booted in recovery mood and managed to boot up as root using the command 'startx'. How can I get back to "my own" log-in from here, with my own settings etc? There's obviously something missing during boot-up but where do I look?
Company laptop HP Compaq 6710b, NTFS on hd0, Win7 installed. BIOS allows boot from USB drive, so wanted to use Ubuntu with no influence on laptop (no disconnecting internal drive, no dual boot, etc). Performed an install from CD to an USB drive making a JFS partition mounted on / and a swap partition. The installer made the JFS partition bootable (boot flag is set) as I asked. On first boot I got:
Dual Booting my laptop and unable to change the Boot Records on the drive. Not because I dont know how, but my primary OS will fail to boot(win7).
I have drive partitioned as follows... sda1 = Win7 system (default install) sda2 = Win7 Main (default install) sda3 = swap sda4 = Extension (I think thats what its called) sda5 = / (ext4)
What I need is a boot cd or perferably Grub installed on a 256MB Thumb drive with the options to load the installed system from sda5.
what's the difference (if any) between choosing to boot from the MBR, the root partition or enabling neither? Referring to: pic23-MBR switch.png - Windows Live Would one be better for dual boots for example? (Using Vista too)
I have a Dell laptop with Windows XP installed, and for various reasons (Help: I borked my WindowsXP boot when installing OpenSUSE 11.3) I can not install a GRUB boot loader to the first hard drive (hd0).
I currently have a second hard drive in this laptop with a perfectly working OpenSUSE 11.3 instance, but no way to boot into it. I remember back in ancient times, a common option with Linux distros was to create a boot floppy to boot into Linux rather than installing GRUB or LILO to MBR. Since this laptop doesn't have a floppy drive I'd like to do the same thing with a USB stick. Is there any way to install GRUB (or something similar) to a USB stick? What I am not asking here is whether I can put a full, bootable Linux instance on a USB drive - I only want a boot loader on USB that launches to the appropriate mount point on (hd1).
this is a strange one. running 11.2 pae 32 bit kernel with all the most recent updates and gnome. This is a fresh install. I built the machine, and then installed all my repositories and software, and used the machine for about 2 days, and now when I log in it hangs on logging into gnome. it's strange because the wireless notification about available wireless networks is in the top left corner of the screen, and nothing else happens. I can log in as root.I also had this issue before I formatted the machine (that's why I formatted)
Recently, I had to switch harddrives on one of my servers due to the need for hardware.
However, when I switched back to the original harddrive I got a surprise : Instead of booting normally in OpenSuse 11.3, it booted in the grub shell.
I did a root ( hd0,1) but when I attempted the setup cmd it failed. Thinking that I probably was a configuration error ( nothing was changed - the drive had spent some time in a nice anti static bag ) I booted using a USB key.
To my surprise I got a message stating that parted couldn't read the other partitions ( boot and swap ) and hence I would not be able to edit then. Fortunately, the data partition seemed OK so I can backup the data.
Preferbly, I would like to be able to restore my original system.
I am using Gentoo Linux and for a while now, the root file system is mounted read-only on booting. For obvious reasons, this is quite annoying as most services do not start up correctly (I do not use a separate file system for /var). After the system is up, I have to log in, remount the root file system read-write, fix /etc/mtab, mount all other file systems in from /etc/fstab and then start up all the missing daemons. I know that there are ways to make a system run properly with a read-only file system, but I would rather restore the old behaviour of a writable root file system.
The strange thing is that after running mount / -o remount,rw, the file system is mounted in writable mode without any errors. I suspected some problem with fsck, but now I have disabled automatic file system checks on the partition (tune2fs -c0 -i0).When I run dmesg, only these lines mention the partition at all, although I am not sure if not something gets lost because /var/log is not writable:
EXT3-fs (sda5): mounted filesystem with writeback data mode</code> EXT3-fs (sda5): using internal journal The line in /etc/fstab looks like this:
I forgot root password. I read that I have to access boot options during start up. I have two choices "desktop", "failsafe". There is boot options below but I cannot access it.
I recently downloaded OpenSUSE 11.3 GNOME for my Netbook. I wrote the image over to my SanDisk 4 GB USB Drive, and it boots on my laptop but not on my ASUS 1004 Netbook. I have already adjusted things like BIOS and Boot Order on the netbook but I am still getting error messages such as "Insert Boot Device" and "Cannot boot from USB". I am trying to make my netbook a dual boot (Windows 7 and SUSE) PC.
I have a linux server running ubuntu 10.04, kernel Linux server 2.6.32-22-generic #33-Ubuntu SMP Wed Apr 28 13:28:05 UTC 2010 x86_64 GNU/Linux. A few months ago I installed ubuntu to a USB flash drive (Patriot 16GB) and was able to successfully boot off it, and everything was running fine. Then all of a sudden I noticed that the root filesystem was read-only, and I saw errors in the kernel log:
I tried reading the drive to see if there was a problem with the drive itself:
root@server:~# dd if=/dev/sdc of=/dev/null dd: reading `/dev/sdc': Input/output error 1966184+0 records in 1966184+0 records out 1006686208 bytes (1.0 GB) copied, 2.12427 s, 474 MB/s
But the strange thing is that if I put that usb stick in a different linux server, I'm able to read the whole drive. If I run fsck, it fixes a bunch of errors, but when I put the drive back in the original PC it will work for a while and then fail with the same type of I/O error (not at the same offset though). I had this same problem occur on a different USB stick in the same server, I had thought it was bad media so I replaced it, but now the same problem is happening on a different usb drive. I have backups of the data, but I would really like to figure out what is causing this before I throw in the towel and buy a new PC.
So I upgraded my hard drive and went with a clean Lucid install. But now I want to get files off my old drive. When I re-hooked it back up (now 2 drives in the system), ubuntu refuses to boot. It kind of boots then just hangs. Never gets to the desktop, and the HD lite on my case is constantly flickering (what could it be doing??)
I have it set up correctly in my BIOS so that the new drive is the boot drive, not the old one. The only difference is that the new drive is sata and the old drive is old school pata (ide). I even tried pulling out the old pata drive and hooking it up to a USB adapter I have. Looking at it in the Disk Manager, it shows it as unformatted, and old faithful GParted doesn't even see it!
Now get this: I pulled out my new sata and put back in the old ide drive and guess what, now it wont boot! Grub (probably MBR) is screwed up also! Any ideas how I can read the data from that old drive? Ether by getting my new lucid install to boot with the old drive as a slave in the system, or by hooking it up externally using USB?
My machine came with one drive installed with XP. I put a second drive in and installed 11.2. Dual boot. I'm replacing the XP drive (keep intact) with a new one but don't want to lose the ability of booting off the second drive. I want the new drive to be first drive in the system.
i have windows xp on main hard drive and installed 11.1 on a usb drive now i have to have the usb to boot windows , and i have to pick windows from the boot loader , any way to remove this as i don't need to usb anymore .
I'm using opensuse 10.2 when I rebooted the my pc I got the message (in the url).P0216_171010 | Flickr - Photo Sharing!I can not boot into tty1 or tty3,5. I tried to repair with Opensuse CD but can not.
I have just installed opensuse 11.4 and the install fails to boot, grub hangs or gives an error.
I have tried installing grub in MBR and root changed every setting I can find and even downloaded a fresh ISO. As a last resort I changed the machines BOIS settings from SATA to emulate ide, booted as expected but a bit slow.
11.2 and 11.3 worked on this machine with no problems. Am i missing something? I also tried an Ubuntu install and this worked fine!
I just did a fresh install of 11.4 and I LOVE IT!!! One of the little issues I am having though, is that there is no login screen. No matter what settings I change it still auto-logs me in.
I am using GRUB and the Boot Loader Location has both "Boot from MBR" and "Boot from Root Partition". Is this right? I would think that I should just boot from the MBR.
I have used Ubuntu 8.04 and uprgaded to the new 9.10 both using the gneom desktop. I wanted to work with KDE and SUSE so I bought the Linux Format magazine with the DVD 126 which had SUSE 11.1 with the KDE desk top. I have a Toshiba L455 laptop and had windows 7 on 110 gb and had ubuntu 8.04 on 50 gb and ubuntu 9.10 ob 48 gb. I had ran the installer and it identified both linux systems and I selected to install SUSE in the space allocated to 8.04. It only boots to suse with the option to select windows. It showes 9.10 mixed with suse. I have not used suse. Is there an uninstall that will allow me to start over with the installation after creating a partition first. How can I get 9.10 to boot or how can I recover data from it.
I have a laptop with a small (dual boot) hard drive. It is a dual boot with Windows XP and Open Suse 11.1. I want to remove Suse Linux but keep the Windows side. I need to keep that Windows drive just the way it is. I have OpenSUSE 11.2 installed in another laptop and want to keep them separate. I don't want to damage the proprietary program on the windows side. My challenge is I do not have aa Windows install CD, I do have the recovery disk that came with the Laptop, but this DOES NOT include the Proprietary program I want to keep. Is there a way to remove Linux from this dual boot drive without erasing Windows?
I've been wanting to start using Linux for years now and after doing some research on which distro to use, I've decided to give it a try with openSUSE and ordered a DVD copy from Novel last night. Needless to say, I'm a newbie to Linux. I'm building a new computer with two identical hard drives and I'd like to install openSUSE and XP on them and hence make a dual boot system. This is also going to be my first time setting up a dual boot. So, while I'm waiting for the openSUSE DVD to arrive, how to actually set it all up?
I am trying to install opensuse on an IBM 8188 desktop with a single SATA hdd. The software appears to load just fine.. standard install but when I reboot the box .. believing it should just boot from the hard drive I get the message no OS installed. I've adjusted the bios and the drive order and I have changed to install parameters for APC or APIC.... you know what I mean... doesn't matter NO JOY IN MUD VILLE.
i have a problem when i use test drive, it doesn't boot into the operating system. it just look like in dos when i login. what is wrong? shouldn't test drive let me see how its look when i use the live CD?
