Debian Configuration :: Bad Superblock On Ext4 Filesystem - Everytime - Computer Powered Off - Clock Resets To 1999
Jan 15, 2010
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.
after a successful installation of the latest debian testing amd64 kde CD-1 iso, the monitor shuts off about 2 seconds after passing the grub2 menu while computer remains powered.
I done searches for "clock" and found similar threads, but no real fix that is working for me. My clock resets when I boot into linux. It does not happen in windows or bios even on cold boots. The battery is replaced and good** the old battery was by all measures dead (0.6v), but still seemed to have enough power for the clock, since windows tested fine with it.
I have tryed setting it to local time, UTC.. etc... My timezone is GMT (london). "sudo /sbin/hwclock --systohc" Although I have windows, I do not use it except the few times to test this, so no conflict.
I'm wondering if anyone knows what will be Squeeze's default filesystem. Will it be the proven ext3 or the newer (sometimes faster, sometimes slower) ext4?
I currently have ext4 and I have nothing to complain about. In fact, my overall experience has been very positive. Ext4 is definitely faster when fsck runs during boot.
What would be the cons of having ext4 as default in Squeeze?
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.

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

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:
I have recently come across a Debian installation page for powerpc: viewtopic.php?t=20481. It got me motivated to fix the Debian I have on my iBook G4. I have a Debian Lenny installed on my iBook G4 -- but I have been having some sort of problem (mostly likely due to hardware) which causes the system to crash. After the latest crash, the clock on iBook has been readjusted. For this reason, I cannot reboot Debian completely.
Every time I turn on the computer it begins the booting process but before I get to my desktop I encounter numerous error messages concerning my clock. After either OK'ing or canceling these error messages, I get to my desktop but the system by then is either frozen or else not working at all. Worse, I can't even turn off the computer since the upper right corner of the desktop is completely blank and I have no menu to turn off or reboot the system.
It took this computer to a local Apple store and they ran many different hardware diagnostic tests on it. They concluded there's "technically" nothing wrong with the computer. But they said although the system has successfully passed all hardware tests, there may still remain some complicated but slight hardware glitch/es which the hardware diagnostics could not pick up.
I have successful upgraded my system from Lenny to Squeeze and have even installed NVIDIA Driver successful, as well as other applications that I need. My system is now running smoothly and okey. My applications are also running smoothly except Skype 2.2 (Debian Forum Guys are currently helping me solve it).
However, I do want to upgrade my file system to ext4 in order to take its advance features and advantages especially that my system is now in WORK HORSE mode. However, I am not confident enough to do it because the guide is limited and does not tackle the issue of a system using ext3 with LVM2 on it.
Therefore, my question is how do I migrate (LIVE) my Ext3 to Ext4 on my system that uses LVM2? A clear and understandable guide is highly appreciated especially that I am newbie on it.
i opened up my browser to surf the web and a page popped up i had never seen before.Apache 2 Test page powered by centos. Any address i put into my firefox browser won't come up and i'm stuck on this test page and,i can't locate it on my computer to remove it.How do i get rid of it and more importantly how did it get on my computer in the first place?
I am having an issue with ubuntu that is driving me slowly mad. When I start the machine there are two keyboard configurations, USA and USA with dead keys, with the latter selected by default. When using punctuation marks I have to hit them twice otherwise they modify the letter I press next. To fix this I simply have to delete the USA with dead keys configuration. However, every time I restart the machine it is back.
Does anyone know why this might be happening? What is the configuration file that ubuntu loads for the keyboard? I am thinking maybe my user doesn't have permission to edit the config file and that is why the changes don't persist past restart. There were some other threads on here with a similar issue however in all of those cases I saw the fix was to make changes to some offending lines in the /etc/X11/xorg.conf. My xorg.conf however does not have a section for the keyboard.
I have a system in which I want to have /etc in a read-only filesystem. What can I do with mtab? It gets write at /etc/init.d/mountall.sh (that is, /etc/rcS/S35mountall.sh)
Every time I restart my computer the screen resolution changes back. I've recently started to use XFCE, it didn't do it in GNOME. what can I do to make it stay the same?
ubuntu 10.04. My computer is left on all the time. My computer's screensaver comes on 10 minutes after last keystroke. Which is fine. However, when I return to use the computer and disengage the screensaver, ubuntu ALWAYS requires my password to continue. How do I stop ubuntu from asking me my password everytime I wake my computer up?
I 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?
I've read some people having the same problem, but I can't manage to fix it. I got a 1440x900 screen. Every time I reboot my system starts up with 1400x1050 , I have to go to System settings to fix it, options don't get saved as one would expect.
Well, I think my problem is cause of nvidia drivers, so I go to nvidia settings to get this fixed. But, these settings are all fine, it says 1440x900. When I try pressing Save to X (to make sure it gets saved), i get a failed to parse message (Failed to parse existing X config file '/etc/X11/xorg.conf'!). I've got driver version 256.53
Oh well, screw this, I'll do it manually, so I go to the xorg.conf file. But over here everything says 1440x900. How come my resolution keeps changing each time I reboot?
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?
A few days ago I upgraded my debian sid system, and since then systemd does a filesystem check on every boot which takes over two minutes, disobeying the existing settings I had. How can I set systemd to do a filesystem check only once every a set number of mounts, like I had set up before the upgrade?
My root filesystems flooded so I'm trying to move it to another (bigger) partition but I'm not sure of the best method. I just tried to use "dd if=/dev/sda1 of=/dev/sda6" to copy it but all that did was give me a brand new partition with no freespace available presumably because the filesystem is smaller than the partition. Is it possible to make the filesystem bigger?
The luksOpen command asks me for my passphrase, but always rejects it. I have retried this several times and written down the passphrase - and even tried with a very simple one just to check. And I never can make it work.
how can I set the keyboard layout used by Debian to enter the password of my encrypted filesystem?
After my recent "aptitude upgrade", I have not been able to mount my encrypted filesystem anymore. I have discovered that the keyboard layout used to enter the password has changed. Problem is that with such layout I can't enter some of the characters composing the password. The encrypted filesystem looks intact, since I have been able to mount it and backup my files by means of a live CD. That means that I can edit any system file, if needed.
Every technique I have found to change layout cannot be employed in this case, since they rely on the system being up and running. I've tried editing /etc/default/keyboard, but that does not work.
"Sleep" is not supposed to permanently kill off the network service. restarting the NetworkManager / network services DOES NOT WORK. Why this blatent and crippling bug is allowed tp persist? I dont want to "rasberry reboot" like windows, this has been the only forced reboot
I thought this might interest someone out there:[URL].. I used SD cards with MBR formatted as ext2 for backup. After I read these articles, I reformatted my cards with GUID Partition Table and ext4 format. Now I make my backup in half the time!
I'm trying to mount a remove filesystem onto my own server. I am able to do this, however I can only access it as root, or if I chmod 777 the lot. Obviously I want to be as secure as possible, so I'd like to avoid either one of those options. Another option is to mount it directly into my home directory, but previously when I was trying out Ubuntu this caused Samba problems - and I was advised mounting in my home dir was a workaround rather than a proper fix.
I have root access with sudo on my own server. I've not set a root pasword, and until I need to I'll avoid it. I have a user account with full control over my own home directory on the remote server. I am mounting using fstab - sshfs#username@remoteserver:/media/sdk/home/username/ /media//remote/ fuse user,idmap=user 0 0
What I would like to do is without changing the permissions on the remote server change the permissions when they are mounted on my own server. I would like them to be in the group sambausers for example. Instead they are owned by root and in the group of 1024 (which I have not set). Additionally for this to work they would have to have 770 on my home server and 700 on the remote server....
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.
