Ubuntu Installation :: SSD With EXT4 Will Not Mount On Boot
Nov 24, 2010
When booting I get the following error message:
Code:
The disk drive for EXT4 is not ready yet or not present.
Continue to wait; or press S to skip mounting or M for manual recovery.
The drive in question is SSD2, which I wanted to mount as an extended disk (non OS). This is what I did:
FDISK:

I'm trying to set up my Fedora 15 installation to automatically mount (with all privileges needed for read/write access w/o a password prompt) an ext4 partition on the same HDD. Below is the output of sudo fdisk -l.
Code:
Disk /dev/sda: 160.0 GB, 160041885696 bytes
255 heads, 63 sectors/track, 19457 cylinders, total 312581808 sectors
Units = sectors of 1 * 512 = 512 bytes
[code]....
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.

Due to a power outage, my EXT4 file systems (which contain /usr and /opt) no longer mount at boot-up. They are, however, seen by disk utility in Knoppix, so I assume the data is still there and that it's just matter of making a connection to it.

I grabbed the new lubuntu 10.10 from [URL] but it turns out I'm having a problem installing it on my netbook (Asus Eee PC 1015PED). While installing, this error pops up:
Quote:
The attempt to mount a file system with type ext4 in SCSI2 (0,0,0), partition #1 (sda) at / failed.You may resume partitioning from the partitioning menu.I'm installing via USB and have selected the option to erase everything and use the full HDD.
Edit: I had Xubuntu installed before.

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.

how to boot Ubuntu from USB flash drive that is formatted ext4?That is, making a portable ubuntu. But not merely a LiveUSB created using the 'Universal USB Installer' or 'UNetbootin' because the LiveUSBs created using these applications are formatted in FAT32 and uses a persistent partition just to save the changes and files.If I have your attention, what we want to achieve is a portable and bootable Ubuntu in a flash drive that is formatted in ext4.

I recently downloaded Ubuntu 10.10 and installed it onto a 250gb removable disk using a 240gb ext4 partition and a 10gb swap space.
I am using a Sony VAIO (VPCF115FM) and it would appear that my BIOS is very limited as to bootup options. I can only choose internal HDD/external device/network/CD Drive. I cannot check whether or not my BIOS is able to recognize the external ext4 (but from experiences so far it would seem that it cannot)
After much tinkering i got my internal windows 7 to recognize the drive as ext3 (Used ext2 volume manager to add a registry entry for the drive). However, I need to unplug and replug in the drive for it to be recognized, if i leave it plugged in from booting it shows up as unrecognized.
Summary: I would like to be able to boot up Ubuntu off this external drive, but as of now it would appear that my BIOS is unable to recognize the drive. Windows can recognize it as ext3, and I can access contents of the ubuntu partition from windows.
how I could get this working that would be fantastic, i've tried formatting the drive to other filesystems (ext3,ext2,XFS) but none of them would work either, so any information would be sweet

I booted into the Fedora 11 on my netbook, and used the desktop icon to install to hard-drive. I specified to use "Free space", and hit next. From there, it just stalls. The "Install Fedora" window does nothing, and I'm going on a half-hour now of nothing.
Tried three times, still nothing.
The first time I tried, I chose to replacce old linux installation (ubuntu), and when I told it to install Fedora 11 root as ext4, it said the boot can't be ext4... so I chose ext3 and it said root device must be ext4...

I live in a country where 1Mbit broadband is a premium service for large businesses. I am paying a little over $40 a month for a 128k connection with monthly capping. I want to download Fedora but the download is just huge for my connection, especially as it is used for work 14 hours a day. I have attempted the LiveCD and got the 'ext4 cannot be used for boot' error. I also have several other specialised distros on this machine and it's going to be a pain inserting a new boot partition just for Fedora.
Like it is possible with Slackware, can I just download the first CD of the Fedora 11 set and get a minimal install from this or does Fedora need the whole set of disks? Is there a simple enough net install option that I could use instead? I can't understand why they can't just release something like Ubuntu's alternate install CD.

I have 4 partitions. One is Ext4 for Karmic, one is NTFS for WinXP, and the other two are Ext4 where I keep all my stuff.When I boot into Karmic and open Nautilus, none of the last three are auto mounted. When I click on one of them, instead of a window popping out asking me for a sudo password, I get a message as shown below.f I try to mount via sudo in terminal it works, but the files for me are then all read-only. Again, if I open Nautilus as root, all works fine.What I want is the following:- for all 3 partitions to automount on startup;- for all 3 partitions to be owned by me and not by root.I tried editing /etc/fstab, but to no avail. Neither did running "chown" help.
/etc/fstab:
# /etc/fstab: static file system information.
#

Still a novice in Ubuntu (Karmic Koala). I'm trying to mount an ext4 20GB partition of my hard drive so that i can use it to store data, i want it to appear on my desktop as well as on places, as far as i know this is achieved by mounting the partition in /media. At my first attempt i used the following commands. (i named the partition ondskapt)
Code:
sudo mkdir /ondskapt
sudo gedit /etc/fstab
in this document i added the following at the end:
/dev/sda4 /ondskapt ext4 defauts 0 0
[Code].....

On this LAN we have: Windows 7 desktop, 192.168.1.2 Ubuntu 10.04 desktop with ext4 filesystem, 192.168.1.5
On the Windows 7 system, how do you mount a Ubuntu "/home/myHomeDirectory" (ext4 filesystem) as "drive U:" ?
So that U: => 192.168.1.5:/home/myHomeDirectory One possibility is a commercial product called ExpanDrive.

I wanted to make a clone of my drive, so I tried the ole sudo dd if=/dev/sda1 of=/dev/sdg1 trick, but first I formatted the drive to the Ext4 format. I wish I would have understood that format a little more before I decided to format it that way. Now I can't access my drive at all. I read almost everything on the net about manually mounting it, but almost everything was in Fat, NTFS, or Ext3/2 format. I even read the Ubuntu documentation. I don't know if it's because my drive is in Ext4 format, or if I'm just not doing something right.
As you can see in the following picture, it recognizes the drive, yet I am unable to mount it. I am trying to access the 160 GB drive. I even tried to see if Windows would recognize it. No go. Today while lurking in the Ubuntu Forums I found a way to make a live .iso of my system (which I think is awesome). So now I want to reformat my drive and use it as storage once again. I think I will restore it to NTFS. I thought that the Ext4 format would work better in Linux (which I was wrong), but now I need Windows to recognize it as well, and it needs to be able to store files bigger than 4 GB (unless you have a suggestion on what to format it as).

I have 250Gb, 500Gb and 1Tb drives concatenated together as one volume group (span) with a logical volume (spanvol). Under kernel 2.6.31.5-127.fc12.x86_64 it mounts totally fine. However, under 2.6.31.6-145.fc12.x86_64, I get this:-

mount: wrong fs type, bad option, bad superblock on /dev/mapper/span-spanvol,

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".

I have been trying to install windows for 15 days and I was finally able to do it by removing in "disk utility" the sign saying that the fedora partition is bootable... but I did it when the partition was active... It showed me a message error but i thought that it told me it wasn't abvle to do it... and now that windows is installed I cannot any more access the partition either in rescue mode and on a live cd ... what could I do to access the partition either to save all the files or to (it woiuld be the best) reinstall the grub ?

I am doing some benchmarking on EXT4 performance on Compact Flash media. I have created an ext4 fs with block size of 65536. however I cannot mount it on ubuntu-10.10-netbook-i386. (it is already mounting ext4 fs with 4096 bytes of block sizes) According to my readings on ext4 it should allow such big block sized fs. I want to hear your comments.
