problem with software raid partition
I have a 4 TB raid5 partition (/dev/md3) on my system.
unfortunately after intensive IO application the whole file system crash and it gave me no choice to shut it down cleanly. so i shutdown system by hardware, after that on startup page, the system stucked on checking file system for a while. After file system check finished it gave me error that said that some errors detected and i should check file system manually (press cnrtl+D to continue or type root password). so i did that by running fsck -pfcv /dev/md3 and also fsck.ext3 -fyc /dev/md3. After around 6 hrs checking file system, none of them works for me and the system still stuck on checking file system and exiting the boot up process with same error.
How can i fix this problem? it is really important for me that all data remains safe.
for your information the system is running centOS 5.8 x64.
