I want to populate an array of string by files exists in directory on mounting of file system. I got an entry point for file system mount. I can use either do_mount function or fill_superblock function. But I am not clear about how to call readdir from there itself. I need inputs for calling readdir from fill_superblock function.

View 6 Replies View RelatedI removed a hard drive from a failed Buffalo LinkStation NAS. The drive was 1TB and formatted in XFS. I installed Debian Linux on my Mac using Virtual Box just so I could get to the files.
When plugin the drive (via USB) two volumes show up, but there's another that I can't seem to open (and may have all of the shared files I need). It's the largest volume (over 900 MB).
I keep reading to run xfs_repair, but when I type that in the terminal, I am given "command not found". I am not sure how to use it.
Also when I try to open the volume I am given "can't open superblock" error.
I am not too familiar with using Linux and ma just trying to get to my files.
How can i read out the superblock of a filesystem?
View 5 Replies View RelatedI am newer to Slackware but not to Linux. I am having the hardest time trying to get my CDROM to mount for me so that I can play audio cd;s and the like. I can see that the system knows that my CDROM drive is there and that it works because I installed Slackware 13 from my CDROM drive as /dev/hdc. Now when I put in a cd nothing happens? I have googled away and searched this forum quite a bit before posting this but I have tried almost everything I can think of and what others have mentioned. I have screenshots to show you what I mean. When I try to run the command:
mount /dev/cdrom /mnt/cdrom
I get it as mounting as read only and it says can't read superblock? Now that is fro my slave IDE CDROM on top as hdd. I have tried before to mount it as /dev/hdc but to no avail. I know both CD drives work just fine because I used them to install the system. I am going to put the screenshots below so maybe someone can help me! Also I can eject the top CD drive with the command code...
I have a removable USB pen drive, that all of a sudden, when it got 99% used, stopped working. When I try to mount it (manually) I get "can't read superblock". I know there is a ton about this on Google and I've read a lot of them, but most seem to be about formatting a drive, or fiddling in fstab. I'm trying to run fsck on it, and it finds errors, (among them: two FAT-tables?) but then it just freezes, and CPU goes to 100 % and I let it be like that for 4 minutes, before aborting. Scandisk in windows is rubbish (fails to start), and running "chkdsk /f F:", in windows, results in nothing, the shell crashes immediately. Is it normal for fsck to get stuck and just chew up CPU? It does not seem to be reading from the drive, according to conky. Also, is it possible to run fsck as normal user, (at my work)?

I have a brand new Dell PowerEdge T110 server with Quad-Core Xeon CPU and 2GB 1333MHz RAM. I have installed a hard disk (SATA, 7.2rpm) on this machine that I removed from another Dell PowerEdge T100 server with Dual-Core Xeon CPU that was running software RAID 1.
Now when I boot the new T110 server, it displays the following error messages code...
I am running CentOs v5.5 x86-64. If I put the hard disk back into T100, it boots fine. I do not know why it is not working with T110 server.
what does this error message mean? im trying to mount an ipod in disc mode. let me know if there is a way to manually mount it to get around this. but not too technical, the simpler the language, the easier i will understand it.

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

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 got a CentOS server + KDE from a server (which I had no contact until now), he had 2 HD's one for the system and another for files.
I brought the HD system home to try to make it run on a virual machine (VMware) so I can do some testing before you put in practice.
But already converted the VMware HD to the system, it tries to start but it shows some errors and in a message "kernel panic - not syncing: attemped to kill init"
I think the drivers are correct, has edited the file "/ etc / modprobe.conf" edited these entries equal to another I installed CentOS on VMware.

I'm looking for a way to launch "TRIM" commands to a SSD drive myself, from a c++ code I'm going to write, for flash erasing an SSD drive (and not to wait for others things that "should do it automatically in some circumstances if this or this, this and this have been enabled and [..]" but will never tell me if it worked or not
I know there is thousands of complicated ways to test and check if it worked, and also software that needs money to do so, that's why I just want to call myself the TRIM functions and read the return value (like true or false) in order to know if it worked !
Where I can find the c++ call that could permit me to do so ? I heard about the GLibC that gives a way to access every user space function related to Linux Kernel (poll, select and others) as standard c++ functions, I suppose that, if there is a way, it will be on the GLibC but how to find it ?

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

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?
