Can't mount a partition?

Question

linux

After an emergency shutdown of the computer, it is not possible to mount the partition. System on Ubuntu Server 10.04
When trying to mount, errors about reading the superblock are thrown

(initframs) mount /dev/sda2 /mnt<br/>
attemtp to access beyond end of device<br/>
sda2: rw=0, want=4, limit=2<br/>
EXT3-fs: unable to read superblock<br/>
attemtp to access beyond end of device<br/>
sda2: rw=0, want=4, limit=2<br/>
EXT2-fs: unable to read superblock<br/>
attemtp to access beyond end of device<br/>
sda2: rw=0, want=4, limit=2<br/>
EXT4-fs: unable to read superblock<br/>

There is also an error when displaying the list of partners

#fdisk -l<br/>
Device Boot Start End Blocks Id System<br/>
/dev/sda1 * 1 32 248832 83 Linux<br/>
Partition 1 does not end of cylinder boundary.<br/>
/dev/sda2 32 1958 15476737 5 Extended<br/>
/dev/sda5 32 1958 15476737 83 Linux LVM<br/>

As far as the Internet suggested, this error is MSDOS and you should not pay attention to it, but still.

#fdisk<br/>
Command (m for help): v<br/>
Partition 1 does not end of cylinder boundary.<br/>
Remaining 5518 unallocated 512-byte sectors<br/>

Since I worked very little with the Linux FS, please tell me what you can see in which direction to kick.

Answer 1

sda2 cannot be mounted, this is an extended partition, only sda1 can be mounted directly
sda5 - this is LVM
, run
# vgchange -ay
All sorts of /dev/VolGroup00/LogVol00 will appear,
you can see their list with:
# lvscan
