I have dual boot system..i.e, windows XP and ubuntu 9.10(insatlled side by side). when i try to boot ubuntu, Im gettin sh:grub > prompt

I am getting something like this.. root mount file system failed.. ext2 ext3 ext4 ....... kernel panic message and hanged at kenelthreadhelpper+ what can i do.. I cant reinstall ubuntu again.. Because I have installed nany application there..
I run an upgrade and an update on a lucid lynx beta 2. --- got no problems. but about the filesystems i have some questions because it seems for me that at every system boot the system will run an fsck. somtimes it's shown up, somtimes not. but in /var/log/messages and in syslog
I have always following messages ( occured in beta 2 too ).
But first before i continue - here my disk layout:
And here my filesystem types:
This is my problem because those values are seems to be static ! ( note: this partiton is mounted but not in use ) and last not least: the drive is an external usb scsi disk. but on the other side lucid lynx is running fine on my box.
how can i locate an Ext2 or Ext3 file system by using the terminal?

Whenever the installation trys to mount the ext4 partition the following error appears: The attempt to mount a file system with type ext4 in SCSI1 (0,0,0), partition #1 (sda) at /failed
Iv'e tried over and over to get past this error to no avail.
I got a problem booting ubuntu 10.4 RC but i solved it by replacing root partirion uuid in grub boot menu then I disapled totally uuid passing to linux from /etc/default/grub . but something else i noticed why grub choosed insmod=ext2 why not ext4 specially I use now ext4 .I tried by editing the grub boot menu replacing "insmod=ext2" by "insmod=ext4" it booted and the three lines error during booting that i used to see them science ubuntu 9.10 totally disappeared . really I dont understand can anybody explane for me.and if what i did was right ,can anybody tell me how to make grub always and permenantly detect ext4 as ext4 not as ext2.
View 6 Replies View RelatedI just rebuild the kernel for slackware 13, everything works, but root file system which is ext3 is mounted as ext2. Normally I've build ext3, ext4 and so on as modules, not in the kernel... but if I do this, then the kernel mounts the file system as ext2, which is build in the kernel. I also modified rc.modules so I can make sure that ext3,ext4,jbd are loaded, but it doesnt work.

How to i can encrypt ext3 or ext4 file system.
I was in the process of installing Ubuntu 11.10, but got stuck choosing which file system to use. ext3 and ext4; which is better for a personal desktop? If ext4 is better, will it work well on my old PC (bought 3 years ago), or perhaps ext4 is not actually compatible with an old hard disk?

How well is the ext4 new file system mounting compatibility with the older ext3 previous Linux installations ? I refer to Ubuntu 9.04 and the new Fedora 11 which have the option to install with the ext4 file format. Will it be better if I install with the older ext3, so that I will be able to mount all other Linux from each other in a multi-boot system ?

Code:
i m not able to copy a file over 16 gigs on an EXT2 or EXT3 partition. Is there a way to do this. I even tried to split my iso file too. I splitted my iso file in 4 files then copy them on the ext2 or ext3 partition. But as soon as I was trying to join the files together it never went over 16 gigs. Actually it stops at 16,843,020 kb exactly. is there a limit for those partitions or is there an another way to see my 20gigs iso file in one piece?

View 2 Replies View RelatedI have a Dell Mini 9 netbook. The SSD took a dump, so I ordered a Super Talent 16gb replacement. I put it in yesterday, tried to install 10.10 and constantly get errors. The first error, which I haven't had since, was [ERROR 30] Read-only File System. The install obviously failed. Wondering if perhaps the file got messed up in translation, I redownloaded 10.10, reformatted the flash drive (sandisk cruizer 4gb), put 10.10 back on via the program on the Ubuntu site. No luck, but no longer the [error 30]. Tried again using Unetbootin, no luck. Rinse repeat a few times, no errors just a working cursor spinning and spinning and spinning and spinning and.. you get it.
Tried to put WinXP on it just because I was that frustrated, no luck.
Now I'm back to Ubuntu (because let's face it, who wants to deal with Windows, christ they make it so complicated). I'm currently using 10.04 because I was hoping (praying) it might just be a 10.10 thing.
No such luck, now it goes to step 7/7, starts, and 5% of the way thry "creating ext4 file system" it says "the ext4 file system creation in partition #1 (0,0,0)(sda) failed." I have checked the SSD in the Disk Utility, SMART tests are clean. I have gone to terminal and run fdisk and had a smarter person than me look at the copypasta, no errors, I have deleted all existing partitions in gparted and started fresh. I have tried the auto partitioning, I have tried manual, I am going insane. Literally insane. My preschooler thinks I've leaped off the deep end.
Could it be my flash drive? Could the SSD be defective despite the tests coming back clean? What do I need to type into terminal? Is there a way to entirely entirely entirely wipe the SSD to make it fresh-out-the-box clean? I will happily provide whatever you need if it means I can get my husband off my back about this stupid netbook with its stupid tiny keyboard.

View 2 Replies View RelatedA friend of mine upgraded his pc to ubuntu 10.04. Sadly enough we ran into issues with his graphics card, which apparently doesnt work well with lucid. We decided to downgrade to 9.10. I did this by installing over the old partition and chose to import the settings from the old account.The problems started when the pc booted for the first time:The list of kernels in grub2 was the one from 10.04.Somehow grub2 from the old installation seems to be still around and messes everything up. Any ideas how I could fix this?
View 6 Replies View RelatedWith the release of CentOS 5.5 ext4 is considered stable in this distribution so I decided to migrate to it. Luckily I started from migrating fresh server with CentOS 5.5 using some instruction I found on the internet. I think I shouldn�t say, that I screwed the whole thing up ;) After about 6 hours cursing, kicking, and crying I solved the task and figured the correct sequence of actions. The small problem with migrating root partition is that you can�t unmount it BTW.
During migration task, I found, that CentOS 5.5 rescue mode is somewhat broken a little in terms of ext4 support. It can mount ext4 partitions successfully. But its e2fsprogs package (tune2fs, e2fsck etc.) doesnt see ext4 partitions and say, that superblock is corrupted on a partition once is converted to ext4 (at least it did it for me. May be I should force filesystem type with -t ext4 switch?). Keep in mind, that if you screw your system up too badly, you will not be able to run tune2fs and e2fsck on it from rescue modeBut you will still able to mount it if it is not corrupted badly. In all below examples,Boot your system normally and login as root. Upgrade kernel if you wish (I usually use yum upgrade to upgrade all on new machines). Then upgrade/install some other packages

View 1 Replies View RelatedI've recently installed Ubuntu 10.10 on a machine, unfortunately, the hard drive was ext3 partitioned. Is there a way of converting this partition to ext4 without having to re-format and hence reinstall the entire OS ?
View 4 Replies View RelatedUbuntu(10.04) was working fine, then some program crashed or something, and I just switched off (power offed) the computer. When I restarted it, this sort of stuff comes:
Code:
mount /dev on /root/dev failed : No such file or directory
and some more lines like that, and then 'Busybox' starts with [intramfs].I booted Ubuntu from a pen drive and ran fsck on the main partition. I just pressed 'y' for a long time (it asks stuff like should it continue repairing or something), and then it was done. I restarted the pc and it booted normally - it looked as if everything was fine.I started google chrome, and it said it couldn't find a personal config file .. ok. Then I tried opening a folder - nothing happens. The system monitor doesn't open, and windows that do open eventually are completely blank. I restarted the pc (this time by doing the normal restart), and it gave me the same 'Busybox' thing.I did the same procedure again, and got the same results. (ubuntu boots, programs dont work, then I restart and the Busybox thing comes again)One More Thing : The Ubuntu installed on the hard disk had all the recent updates (including the latest linux kernel) while the pen drive thing was around 2 months old I think. So maybe that's the cause?
I have been able to get most of the way through the process of changing from using ext4 back to using ext3, but something is not quite right so my system does not boot properly.
I have a system that was running Karmic Koala 9.10 as a server (no graphical environment). I had two drives using RAID1 with LVM on top, where the logical volumes of oldvg (old volume group) were using mostly ext4. /boot was not part of the RAID: it's on a separate physical drive and uses ext2.
I recently added two more drives and used RAID1 and LVM, and made all lv partitions (/, /usr, /var, /tmp, /opt, /home, /srv) ext3. I used rsync to duplicate the contents onto the logical volumes of newvg (new volume group). I was careful with rsync's option switches, and this part seems to be fine.
I also edited (the new) /etc/fstab and changed the UUIDs of the seven mount points to point to the logical volumes that are part of newvg instead of oldvg, and added new entries to (the new) /boot/grub/menu.lst to refer to newvg in addition to those that I left around to refer to oldvg.
This wasn't sufficient: rebooting here failed, but I went in with a rescue disk, and first updated /boot/grub/device.map to include the new physical drives. I then mounted all the new logical volumes, mounted boot also at its proper place, and entered a chroot of the new system as it should be mounted. Once there, (and after making a backup of /boot) I ran "update-initramfs -k all -c" to rebuild the initrd images that were stored on /boot. Finally, I also edited /etc/mtab so that the two entries that referred to oldvg now refer to newvg instead.
Now, the machine begins to boot from newvg, but the console text includes messages like:
And a bit later,
Now, at this shell if I type mount, I see:
I am actually confused as to why there are only entries for /root and /var in /etc/mtab, actually, instead of entries for all of the main mount points. I am thinking it must be part of the boot staging process, because there are entries for newvg-usr, newvg-tmp, etc. in /etc/fstab.
When I type any of pvdisplay, vgdisplay, or lvdisplay, I get
In fact, even if I run lvm, I get a similar error:
However, if I go back to the rescue cd, pvdisplay, vgdisplay, and lvdisplay do show that all of the partitions from both the old and new volume groups are available.
since running update manager on my daughters net running 10.04 netbook on boot up I get the following on the screen
