Record the mount problem once

Linux CentOS 6.5 _64 Oracle 11.2G

Today received a customer call said restart the server, the database did not restart to see the database error did not find the control file path, the database started to the Unmount State,

Because the database is placed on the storage, the database program installed on this machine, df-h view storage without Oh mount, execute mount/dev/sdc/u02 error/DEV/SDC has been mounted or/u02 is busy.

Again df-h still did not see, Ps-ef view has the following information:

Sh-c/SBIN/FSCK-YF/DEV/SDC >/dev/null 2>&1

/sbin/fsck-yf/dev/sdc

Fsck.ext4-yf/dev/sdc

Re-mount/dev/sdc/u02 after kill for the above three processes

Then Sqlplus/as SYSDBA.

ALTER DATABASE Mount;

ALTER DATABASE open;

Check everything is OK. Call it a call.
