- - FSCK issue? (https://www.linuxquestions.org/questions/linux-newbie-8/fsck-issue-661981/)

I have been stuck with running of fsck on my one of LVM partition.Whenever I run the following command:

Code:

[root@BL08DL385 ~]# fsck  /dev/VolGroup00/lvmydata

fsck 1.35 (28-Feb-2004)

e2fsck 1.35 (28-Feb-2004)

The filesystem size (according to the superblock) is 4194304 blocks

The physical size of the device is 2883584 blocks

Either the superblock or the partition table is likely to be corrupt!

Abort<y>? no



/dev/VolGroup00/lvmydata contains a file system with errors, check forced.

Pass 1: Checking inodes, blocks, and sizes

Error reading block 2883586 (Invalid argument) while doing inode scan.  Ignore error<y>? no



Error while scanning inodes (1441792): Can't read next inode

e2fsck: aborted

[root@tuxbuddy ~]# fsck  /dev/VolGroup00/lvmydata

I continued pressed the y key for 1 hour but still its not letting me done with the repair.

I did tried -y or -A option but cant help to repair the same.

Pls Help

This is important:

Code:

Either the superblock or the partition table is likely to be corrupt!

The filesystem size (according to the superblock) is 4194304 blocks

The physical size of the device is 2883584 blocks

You have a file system that is twice the size of the allotted partition space! This must be fixed.

First, check that the partition table make sense. If that is correct, then run fsck using an alternate superblock, because this primary appears incorrect.

I dint get you.What it really means?
Can you tel what i need to check or what steps I need to follow to get rid of that error?
I have mysql installed on that partition and the error was thrown when trying to run mysql and its not starting.

Anyway Pls Help me steps by steps how to get rid of the problem?

What is the output of

Code:

pvdisplay

lvdisplay

Also, here are some overviews on using LVM. Its worth getting to know a technology if you are going to use it, because someday, you'll have to debug it.

When I run # df -h it shows lvmylog as 16.00 GB but here above it is showing 20 GB Donno Why?

MySQL is using this partition and thats why unable to start up?
