Hi Frd,

I am using RHEL -4 U5 . Some actvitity in my office in last weekend. that why server poweroff.

Restart server and suddenly iam facing prolem (At booting Time).
------------------------------
ata1 : status=0Xd0 {busy}
SCSI error: <0,0,00> return code=0
additional sense :SCSI parity error
end_request: I/O error ,dev sda,sector 82567012
Buffer I/O error on device sda8,logicalblock 23330538.
-----------------------------------------------------------

i am using sda8 as Oracle data . this mount under /u01.

Some Anothee Error : is Ext3.fs contaent not ....etc

Solve This problem i am using this ...Method

1) File system must be unmounted, you cannot repair it while it is running. Take system down to runlevel one (make sure you run all command as root user):
# init 1

2)Unmount file system, for example if it is /home (/dev/sda3) file system then type command:
# umount /home
OR
# umount /dev/sda3

3) Now run fsck on the partition:
# fsck /dev/sda3

However be sure to specify the file system type using -t option. Recenly one of our sys admin run the command on ext3 file system w/o specifying file system. Result was more corruption as fsck by default assumes ext2 file system.
# fsck -t ext3 /dev/sda3
OR
# fsck.ext3 /dev/sda3

Tip if you don't know your file system type then typing mount command will display file system type.

fsck will check the file system and ask which problems should be fixed or corrected. If you don't wanna type y every time then you can use pass -y option to fsck.
# fsck -y /dev/sda3

Please not if any files are recovered then they are placed in /home/lost+found directory by fsck command.

But i am not resolve This .
Can some budy help me on this...
