How to force disk check (fsck) in Linux.

One way to determine if the drive is failing in Linux is to run the following command in the terminal

dmesg | less 

This should give you an error list you can scroll through for read/write errors.  
If you see a problem on a data drive perform the following:

1. Stop the exacq vision server service
   sudo /etc/init.d/edvrserver stop<br><br>
2. Unmount the drive that is having trouble
   sudo umount /dev/sdb1<br><br>
3. Run file system check on that drive
   sudo fsck -f -y /dev/sdb1<br><br>
4. Reboot the system.

If the problem shows on the master drive you will need to do the following:

1. Login as the root<br><br>
2. Change directory to root (/) directory
   cd / <br><br>
3. Create a file called forcefsck
   touch /forcefsck <br><br>
4. Now reboot the system
   reboot<br><br>

The system should run the disk check when it boots back up in to the operating system.
