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 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:-
[root@undertaker ~]# mount -t ext4 /dev/mapper/span-spanvol /home mount: wrong fs type, bad option, bad superblock on /dev/mapper/span-spanvol, missing codepage or helper program, or other error
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

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 hv 3 os installed ...windows7,ubuntu9.10 and redhat5.3can ne1 tell me how to mount ext4 partition from redhat....because after installing redhat ubuntu is not booting....or can ne1 tell me how can i boot ubuntu by editing grub.config
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'm currently building a Raid5 Volume Set (HW-Controller, 3 disks). After some diskussion I decided to don't use a partition since I don't see any disadvatages writing the filesystem (ext4) directly onto the device.
Because I plan to expand the volume set with 2 more hard disk drives, respectively the filesystem, to get the complete disk space available I read the ext4 manual. There is an extended Option called max-online-resize with the description:
Well, although I've searched for more details on the internet I can't find any. Primary in which case is it usefull to set this value because later resizing should be possible without to set this value. Maybe it accelerates the resizing process?
Next, I also plan to use the options stride=stride-size and stripe-width=stripe-width. Is it advisable to set these values for the final volume set (Raid5 with 5 drives) or do I have to set it for the first volume set (Raid5 with 3 drives) and then changing these values during the later resize process for the filesystem? (I personally prefer the first method).
I used the usual 'mkfs.xfs -l size=128m,lazy-count=1 /dev/sdX' at creation. After that, I would like to use custom mount options like: This goes instead of the "defaults" part in /etc/fstab
I receive the following error at boot: INVALID log iosize 4 [not 12-30] << No one used iosize 4... what does it mean? it is connected to the options..but which one? (At the minute I'm usig it with: noatime,nobarrier).
i am trying to compile kernel 2.6.23 on Fedora 12 After fixing a few bugs (getline error, %dil ,etc) i was able to compile the kernel made initramfs img using dracut updated grub and then booted up the new kernel 2.6.23 but it fails to boot with following error mount: unknown filesystem type 'ext4'
I have a 2 TB hard drive in an external USB caddy that I use for backups. The drive gets automatically mounted when connected to F13, which is great, and the default mount options it uses are:Code:rw,nosuid,nodev,uhelper=udisksHowever, I want to add an extra option or two but I don't know where I can do this. Does anyone know where I can add mount options onto the default set?
I just installed F13 x86_64 on a system that used to be running Windows 7.
The boot drive is a SATA drive attached to the motherboard which is working fine.
However, my data drive is an NTFS partition filling a 3.6TB SATA raid.
It's GPT--Gparted sees 3 unknown partitions, and gdisk shows:
Code:
How do I mount this in Fedora 13? I had intended to shrink the NTFS partition so that I can create an ext4 partition to move the data to. Will this be possible?
I've got a LOT of valuable data on this drive, and nothing else big enough to store it.
Linux box info: root@mytestbox:~# uname -a Linux mytestbox 2.6.32-30-generic-pae #59-Ubuntu SMP Tue Mar 1 23:01:33 UTC 2011 i686 GNU/Linux
Windows box info: Windows Server 2008 SP2 Enterprise I've verified via --verbose output that mount.cifs is indeed processing the passed on options.
root@mytestbox:~# mount -t cifs //10.1.1.10/Test /root/testwin --verbose -o credentials=/root/testcreds,rw,nocase,noperm,noacl,nounix,noserverin o,iocharset=utf8,file_mode=0777,dir_mode=0777
[Code]...
Yet, when I type mount all it reports is (rw,mand). The share works just fine, and I can see the masking (all files are showing as rwxrwxrwx as expected etc) but mount is not listing the options?!
Is this normal expected behavior? Is there a bug report on this? I've google'd to the best of my capabilities and could not locate any such information which is why I decided to hit the forums prior to filing a bug.
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:
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
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: Code: Disk /dev/sdb: 64.0 GB, 64023257088 bytes 255 heads, 63 sectors/track, 7783 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00029baa

I have a 1TB external HDD I used for backup, formatted as ext4. One day it decided it would no longer do anything. It doesn't mount, shows up as "unknown" in gparted, and Testdisk hasn't found any files on it. Logs from testdisk: [URL]
I have installed both Windows Xp and Fedora 12. Last time when i was working on Fedora it didn't shut down properly. Now following error occurs and finally the system sleeps.

I am running the latest debian lenny OS and with kernel 2.6.26-2-686. I have a common /data partition for both Ubuntu and Debian which is ext4 file system. I am not able to mount this volume. The error message reads "unknown filesystem type ext4". How do I fix this. I searched the net and there was a link talking about this
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.
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 a bunch of nfs mounts from my MythTV backend to my netbook, both running 9.10. Due to the lousy Atheros wireless driver, it typically loses connection at least every half hour. The nfs mounts are mounted soft,intr, so programs should get an error trying to talk to a server they can't contact, and the request should be interruptable. Instead, they just lock up, can't be interrupted, and the netbook can't even shut down after the network failure because it hangs trying to clean up before shutting down.
So do these nfs options actually work in Ubuntu? 'mount' shows the nfs directory mounted with the correct options, so it doesn't seem to be any kind of configuration problem... it just doesn't do what I'm telling it to do.
