Record a mount problem and record the mount Problem

Linux centos 6.5 _ 64 oracle 11.2g

Today, I received a call from a customer saying that the server was restarted and the database was not restarted. After reading the database error, the path to the control file was not found. The database was started to unmount,

Because the database is stored, and the database program is installed on the local machine, df-h shows that the storage is not mounted, run mount/dev/sdc/u02 to report the error:/dev/sdc has been mounted or/u02 is busy.

If df-h is not displayed again, ps-ef displays the following information:

Sh-c/sbin/fsck-yf/dev/sdc>/dev/null 2> & 1

/Sbin/fsck-yf/dev/sdc

Fsck. ext4-yf/dev/sdc

Run kill on the preceding three processes and then mount/dev/sdc/u02 again.

Then sqlplus/as sysdba

Alter database mount;

Alter database open;

Check that everything is normal. To close the work.
