Ubuntu :: EXT4 Partition Is Not Mounted On Startup?
Nov 11, 2010
I have two ext4 partitions: one with Ubuntu 10.10 64-bits and the other just for storing files.When I log on to Ubuntu, my second partition is not mounted. Shouldn't Ubuntu mount my second partition by default (since it recognizes it as ext4)?If it should, why is this happening to me?If it shouldn't, how can I get my second partition to be mounted at startup? Should it be by using the same solution provided by prayag_pjs (first reply)[URL]

I had 5.4 machine. Upgraded to 5.5 today via yum upgrade. All went fine. Rebooted. Wanted to convert root partition to ext4 (I have three partitions: /boot, / and swap). All of them on software RAID 1 (root is /dev/md2). I did the following for converting
yum install e4fsprogs
tune2fs -O extents,uninit_bg,dir_index /dev/md2
nano /etc/fstab # I indicated here that my /dev/md2 is of ext4
[code]....

I'm on Slackware-current and I've got a /dev/sda1 (the root partition) formatted as ext4. The output of /etc/fstab is:
Code:
/dev/sda2 swap swap defaults 0 0
/dev/sda1 / ext4 defaults 1 1

I upgraded F10 to F11 successfully.
Then I convert the / partition filesystem by the following steps:login as root user in multi user mode read [url], and execute tune2fs -O extents,uninit_bg,dir_index /dev/mapper/VolGroup01-LogVol00 modify /etc/fstab, change the type of / to ext4
reboot
(because fsck say running it on a mounted filesystem can cause filesystem damage, so i decide to reboot to single user mode first. maybe it's a mistake here) try to boot F11 to single user mode, failed
reboot from a SystemRescueCD-1.2.0 LiveCD
run e2fsck -fpDC0 /dev/mapper/VolGroup01-LogVol00 in SystemRescueCD-1.2.0 LiveCD, no error reported
reboot
try to boot F11 normally(multi user mode), but it failed at: EXT3-fs: dm-0: couldn't mount because of unsupported optional features (40).
I tried rescue mode of Fedora-11-i386-netinst.iso after these steps above. The / partition can be found and mounted to /mnt/sysimage correctly. I can read/write files in / partition, and i can even yum new softwares in rescue mode, but it just can't be mounted when booting.

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?

Is there a program that will reread the partition table and update the kernel even if one of the unmodified partitions is mounted? I installed my system on one partition, then I added another with free space. Now I want to format the second partition, but the kernel doesn't know about it yet. I tried sfdisk -R /dev/sda, but it refuses while the root partition is mounted. Is there anyway I can avoid rebooting?

I want to convert a vfat partition into an ext4 partition. This is on my wife's machine and she deleted the Windoze partition as she now prefers Linux. Here is the (edited) output from fdisk -l:-
/dev/sda2 514048 4708351 2097152 83 Linux
/dev/sda3 4708352 6805503 1048576 82 Linux swap
/dev/sda4 52693200 234436544 90871672+ f W95 Ext'd (LBA)
/dev/sda5 59006800 234227699 87610446 83 Linux
I want to change /dev/sda4 to 83 to free up space for Linux without losing the partitions in this 'extended' partition!

using suse 11.3 and kde 4.4.4 on the mounted fat32 partition I cannot change icons partition is mounted in fstab in this way:/dev/sda8/ /dati vfat user, users, gid=users, umask=0002, utf8=true, 0, 0.I can create files folders modify, move and save them on the partition but if I try to change the icon (in dolphin right click>properties>click on icon) of the /eros folder (or any other folder or link) system gives me
this error:impossibile salvare le proprieta' , non hai accesso sufficiente per scrivere su /dati/eros/.directory tha in english is something like this: impossoble save properties, you havent enough permission access to write on /dati/eros/.directory this happen also as superuser I remember that with suse 11.0 or 10.3 I was able to change icons on fat32 partitions, now with 11.3 I cannot, there ought to be a way to do what I did with the previous version with this 11.3 brand new ad more advanced version shouldn't it?

I want to have a shared folder mounted on startup and I put the following in my fstab:
Code:
VMShare /media/VMShare vboxsf defaults,gid=1001,dmask=002 0 0
Where did 1001 corresponds to the virtual share group.
When I boot up the permissions are as follows(from ls -l):
Code:
drwxr-xr-x 1 root virtualshare 68 2010-10-27 15:45 VMShare/
So I'm curious why it's group permissions aren't the same as owner? In the fstab I put dmask=002 which should lead to rwxrwxr-x so basically full permissions for owner and group and read/execute for public. However thats not what I'm getting. Also once I get this working correctly am I going to have an issue if the virtualshare group isn't a users primary group? On some older unix servers I ran into this issue, hopefully it won't matter as long as the user in in the group.

I added a 1TB USB drive to a Red Hat 5.3 system. I added the following line to the /etc/fstab to automount the drive at startup.If I manually the mount the drive (mount /mnt/external), I can access and read/write to the external USB drive without any issues. My problem is that during the startup process after a reboot, the drive is not being mounted automatically.

Currently I have a four partition setup: One ext4 /boot partition for Fedora, one LVM partition, one ext4 partition (which has Ubuntu), and one swap partition. What I would like to do is shrink down the ext4 partition which has Ubuntu on it and increase the size of my LVM parition (and increase the Volume Group, filesystem, etc. within the LVM). However, I've been searching on Google and the only solutions I find is to make the free/unpartitioned space and then create a new LVM partition and stretch the VG over the two LVM partitions. However, I already have 4 partitions, so I can't make the fifth one.
Is there any possible way I can increase the size of the underlying LVM partition itself?

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

I recently bought a new HDD for my server and I now need to create two differently sized ext4 partitions. I tried GNU parted, but it can't create ext4 partitions so I did some googling but couldn't find any CLI partition managers with ext4 support
Btw, the server is running Ubuntu 9.10 x64 Server.

I'm having a problem with GParted. I'm trying to increase the size of an ext4 partition but the maximum is set to 9970 MiB. The option to increase its size is greyed out. How can I fix this?

I used gparted to format a 360GB partition with ext4 and I expected it to have at most several hundred MB used for whatever reason by the file-system, but it said 18GB were used. How come? Are there any file-system settings I should have paid attention to?

I have recently updated my ubuntu 9.10 install to 10.04. And with that I've tried to install snow leopard on my computer so i can dual boot between them.the install was successful, but grub2 (that worked fine) wouldn't see the OS X install on its own partition. so i tried reinstalling it, like you do after you install windows and it would remove grub as the bootloader.That didn't work and i got a lot of messages that it wouldnt work because my partitioning (or something like that) is GPT. by the end of it i didn't have grub installed at all!so i started playing around with GParted, and while doing that i also put a bios_grub flag on my main ubuntu install partition, thinking that it would force grub to load from that partition. But that just gave me the GRUB Rescue prompt when trying to boot.
So i unchecked the bios_grub flag. and now it doesn't boot to anywhere and when inserting the ubuntu live cd i cant even see the ubuntu ext4 partition and mount it.Gparted says that its a partition that its File System is undetectable and unknown.Is there any solution that will allow me just to mount that partition and copy files from it? (unfortunatelly my backups are a little older than i would like them to be)Heres what boot info script gives me: (the partition that i need is sda1)
Code:
Boot Info Script 0.55 dated February 15th, 2010

I was wondering if it's somehow possible to install the Live USB to an ext4 partition, this because I have a 4gb filesize limit on fat32 and that means I cannot make the casper-rw any larger. And next to that I can decently manage permissions on that.
