I'm logged into a server through the CLI and did a df -T and confirmed all my volumes are ext3. but when I do a tune2fs -l /dev/sde it tells me
tune2fs 1.39 (29-May-2006)
tune2fs: Permission denied while trying to open /dev/sde
Couldn't find valid filesystem superblock.
I don't have root access on the server, but is that why it's complaining, or is my syntax incorrect?
Specifically, I'd love to know what the valid values of:
And, where I can find this information? I've always wondered if it was documented somewhere, or if there was an interface into the kernel to query for it.
Running ubuntu server (ie no gui) but suspect this might be a general problem.
With the machine booted from the hard drive, if I run fdisk -l I get an invalid partition table message code...
Unable to read the contents of this file system!
Because of this some operations may be unavailable.
How do I correct this error?
How can i read out the superblock of a filesystem?

This problem has arrived again.......I tried the same solution but didn't work out...the problem is described below.
I use Ubuntu 9.10 .
I did this in Ubuntu 9.10 live CD.
quote from terminal :-
ubuntu@ubuntu:~$ sudo mkdir /win
ubuntu@ubuntu:~$ sudo mount /dev/sda5 /win
ubuntu@ubuntu:~$ sudo mkdir /vdisk
ubuntu@ubuntu:~$ sudo mount -o loop /win/ubuntu/disks/root.disk /vdisk
[Code]....
The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem (and not swap or ufs or something else), then the superblock is corrupt, and you might try running e2fsck with an alternate superblock:
e2fsck -b 8193 <device>
ubuntu@ubuntu:~$ "
> ^C
ubuntu@ubuntu:~$
^^ quote ends.
I added an ext4dev filesystem to my hard drive as /dev/sda3 and mounted at /share with the goal of putting all of my multimedia files on it and sharing it through NFS. I followed this guide: [url]
Of course, this was from lenny (hence the -dev). The partition was fine, and I mounted it numerous times. I also performed a dist-upgrade to squeeze. I shutdown that computer with the usual 'shutdown -h now' and disconnected the AC power cord from it, because I wasn't planning on using that machine for awhile. As far as I could determine, everything was fine before I unplugged it.
Every time that computer is powered off, the clock resets to 1999 because the battery is bad. So I am used to getting the "last mount time is in the future" error.
Three weeks after halting, I powered the computer back on. It was unplugged until this point. I got an error message when it attempted to mount /dev/sda3
I then removed its line from /etc/fstab, rebooted. and tried to check it, but I just keep getting the same error-- even with the '-b 8193' option.
The machine is still using the 2.6.26 kernel from lenny. I am building a new one right now (2.6.30), hoping that the problem is caused by the ext4dev/ext4 module. Otherwise I don't know what to do.
When i install libdrm, i get the following error:checking for clock_gettime... no.checking for clock_gettime in -lrt... no.configure: error: Couldn't find clock_gettime

View 11 Replies View RelatedI have a x64 OpenSUSE server with two hard drivers installed. The first one is used for the / and /home partitions and the other is for backups. Ironically enough it is the backup hard drive I am having trouble with. I was having trouble writting to the drive and unmounted it to preform a fchsk, however now when ever I try to mount it I get the following error:
mount: wrong fs type, bad option, bad superblock on /dev/sda1,
missing codepage or helper program, or other error
In some cases useful info is found in syslog - try
dmesg | tail or so
Does anyone know who I can repair the drive and retrive data?
After several crashes during videos it seemed like a good idea to fsck root. Downloaded the latest systemrescuecd and ran it at boot. The error message was 'bad magic number, corrupt superblock' with a suggested command to try another superblock. That failed with the same message. Tried tune2fs to force fsck at boot and got the same message. The drive is less than 6 months old and the installed system is working more or less ok. The command I used was 'fsck.ext4 /dev/sdc2'. What am I doing wrong?
View 9 Replies View RelatedI recently upgrade to Fedora 14 from 13. It was an in-place upgrade. I can't recall for sure, but I do believe I had these problems in F13 before the upgrade. The F13 install was from a Live CD. Anyway, I have a three drive RAID 5 array setup - 3x 750GB. For some very annoying reason, each time I reboot my F14 system, it hangs with an error about not being able to find a superblock on /dev/md126 and /dev/md127. I have tried to stop and remove /dev/md126 and /dev/md127 but they always seem to come back. I have also noticed in the output of fdisk -l that drives sda and sdd like to swap places sometimes for an unknown (to me) reason. Any other output that is needed, please ask. I recreated the array just yesterday with:
Code:
mdadm --create --verbose /dev/md0 --level=5 --raid-devices=3 /dev/sdb1 /dev/sdc1 /dev/sdd1
I would cat mdadm.conf in /etc, but I removed it previously to try to figure out the problem and it was not

I did a tune2fs -l on some volumes of mine, and a few say "not clean" as the filesystem state. But how do I tell what's causing it to be not clean, or how severe it is, so i know how soon i need to schedule downtime to run a e2fsck on that volume?

I'm relatively experienced with UNIX and Linux, but this has me thrown for quite a loop, and it seemed like such a simple question. How would I go about finding the newest file in a file system? I thought something like:
Code:
ls -ltr `find /usr -type f`
would work, but I seem to be exceeding the argument maximum for ls:
ksh: 0403-029 There is not enough memory available now
I thought something involving xargs might work, but I really suck with that command.
Fstab has at the end some values: 0 1 for / or 0 2 for /home or others.
It is nice to set tune2fs -c 2 for disks that have to be reliable and increase the security of the data.
tune2fs is not working for JFS. How to make this check at every single boot of the Debian/ubuntu machine?

I have a server running centos 5 located in a datacenter. I am setting it up as a web server but haven't bothered to move the domain from my current registrar to the server as there are a lot of things I need to get done before that. I am having a problem where I couldn't install httpd. So i tried some of the basic fixes i knew as far as yum clean all and checking that my /etc/resolv.conf was ok. I have the two nameservers I am using listed there but I have no hostname set because I simply dont have the domain transferred or anything like that yet. Is that the reason I am having these issues. I installed the system with a network install fine about a month ago so im not sure why I am having problems now.When i try to ping centos.org I get an unknown host www.centos.org error. I tried changing the resolv.conf to have localhost as the hostname and I still have the same issues. I havent made any changes to anything that would potentially cause this.
My etc/resolv.conf looks like this:
search
nameserver 12.34.567.8
nameserver 12.34.566.8
Also it seems the problem may have got worse after yum clean-all because before that when I would try 'yum install httpd' it would show the files and filesizes and ask to install, when I would select yes It would give an error showing it could not find the fastestmirror. Now it doesn't give any file size or files or an option to approve the install. It just responds with an error saying it could not retrieve mirrorlist
