I'm having some problems with errors reported by fsck on my EXT4 root partition on my Ubuntu 10.10 installation... If I run fsck I get the following output:
Code:
# fsck -n /dev/sda1

I installed 2 new hard disks and created one ext 4 partition on each of them. After rebooting busybox tells me that there is no /sbin/init.
View 7 Replies View RelatedI have a usb flash drive and according to sources I found out after the fact that I should have used ext2 instead of ext4 due to the extra write operations.
Is it possible to convert the ext4 root partition to ext2 or do I need to backup, reformat, and restore?
With 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
I've a flash drive that it's partitions formatted as fat32, ex4 and encrypted ext4. It works fine on the system that I've formatted it on, but when I try to use it on my other Linux distributions I get these problems:
* ext4 partition accessible by root only.
* after entering my pass-phrase I get
Code: /dev/mapper/udisks-luks-uuid-***** uid1000 is mounted What I'm asking for is a way to create the ext4 file system without being attached to some UID and to be accessible by any user.
I am dual booting Ubuntu 9.10 with ext4 and OS X with hfs+, and I'm getting tired of having to go through Open Firmware, rEFIt, and GRUB to boot to Ubuntu by default. I've done a lot of digging, and my results appear to be inconclusive. I have, however, been able to hypothesize that the reason that I cannot set my ext4 partition as the Startup Disk (via OS X settings) is because OS X does not know how to read ext4. I believe that the Startup Disk settings work by writing to Open Firmware, so I'm thinking that maybe something else would be able to as well, preferably something that is capable of reading ext4.

Partition table entries are not in disk order I'm trying to automount /dev/sda8, I believe. I'll check that when I've rebooted to by Ubuntu partition, 'cause that's where I know how to do it. I tried to use pysdm, since that's what I used to do the same thing in Ubuntu, but it wasn't found by the Fedora package manager.

I just installed ubuntu via the windows executable and I couldn't mount my NTFS partition. I found this a little odd and I checked fdisk and it seems to think I don't have an ext4 partition as my entire internal HD is displayed as NTFS.
Here's the fdisk output:
When i try to mount the NTFS partition /dev/sda2 i get the following output:
I can't make heads or tails out of this. Anyone know what's going on here?
Windows recognizes that 30GB were taken from the NTFS partition for my linux install. It reads the max partition size as 465GB. fstab reports the NTFS partition size as 488GB.
I have an external 320gb Hard drive. My plan was to have 250gb for My Documents of mainly music, films and word documents. And 50gb set aside for ubuntu, in a separate partition.To do this I need to partition the 50gb partition as ext4? then add a swap file of how big? Do i even need a swap space if I have 4gb of physical RAM?

I was wondering how to check the current mount options of my ext4 filesystems in Fedora 12? The only thing I can see in fstab is "defaults" but how can I know what is behind those defaults.mount command only shows "/dev/sda6 on / type ext4 (rw) but nothing else.I'd like to know a few more things like the data mode used like "ordered" or "journal".
View 2 Replies View RelatedI posted this first to thread 'Boot problem - "Gave up waiting for root device.", (initramfs)' then realized that I should start a new thread because the problem is not the same. On boot the splash goes black and nothing happens, On a recovery boot it drops into shell BusyBox and messages indicate that the root partition cannot be found. After booting from CD Gparted GUI partition information shows no label or ssid for the root partition sda2. The data for the root partition appears to be there. how to fix this? My /home, swap, and / are on separate partitions formatted ext3. I have a recent backup only for my data. I would like to avoid having to rebuild my system from scratch.
View 9 Replies View RelatedI would like to dual boot Ubuntu and Windows 7. I have Ubuntu 9.10 Live CD and Windows 7 Pro Live CD. Ubuntu is installed but Windows 7 isn`t. I have gparted installed. I found the following directions within Ubuntu documentation.
Master Boot Record backup and re-replacement
Back-up the existing MBR, install Windows, replace your backup overwriting the Windows boot code:
Create an NTFS partition for windows (using fdisk, GPartEd or whatever tool you are familiar with)
Backup the MBR e.g. dd if=/dev/sda of=/mbr.bin bs=446 count=1
Install windows
Boot into a LiveCD
Mount your root partition in the LiveCD
Restore the MBR e.g. dd if=/media/sda/mbr.bin of=/dev/sda bs=446 count=1
Restart and Ubuntu will boot
Setup grub to boot windows
I don't want to backup the MBR and restore as listed. I would rather use the Ubuntu Live CD to reinstall the GRUB.
How do I overwrite the MBR?
Do I use gparted and change the partition?
Do I create an NTFS partition as listed above?
Or what do I need to otherwise do to boot the Windows 7 Live CD so that it will install?
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)

View 2 Replies View RelatedRecently, 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.
First time trying anything like this. I'm running a Abit NF7 with a silicon image 3112 that's support was broken in 2.6.35. I get a kernel panic when VFS can't find the root partition, I can't remember the exact line (can't log it, root isn't mounted yet) but it says something like sata1: link down (sstatus 0 scontrol 0). I think there might be a more telling error message before, but it flies by too fast to see or capture with my camera video recorder.
There's a patch that reverts back to when there was a delay in /drivers/ata/libata-sff.c in the function ata_sff_tf_load, by calling ata_wait_idle(ap) which fixes the issue for some people but not my system. I don't know anything about what I'm doing, but I thought I'd go through and add printk's in each function in sata_sil and see how far the device was initialized. I did this but they all happen early in the boot that flies by. Is there any way to add a pause like the "more" command? [URL]
I need a reliable+fast filesystem for root and boot partition. It will be used in Debian x64. So far I only tried ext3 and ext4. What do you reccommend? (this has been probably asked many times, but I need updated information)
View 2 Replies View RelatedI 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 use one PC only, I paste some files and folders into the U1 folder. Files upload to the webstore, I can see them via the web. Now, *what* is subsequently used as a *reference* for content? For example, what should happen if I rename a folder in the PC U1 folder? Should the new name later appear appropriately on the webstore? What should happen if I use the web access, and delete a folder in the webstore? The PC U1 folder remains full, does the web store get filled and corrected? At a time when the webstore is complete and correct, if the contents of the PC U1 folder is deleted by me, will the webstore contents act as a form of backup? Or will the webstore contents also get removed by U1 process?
