ORA-27301: OS failure message: No space left on device

Im unable to start the database. It gives the error:-

ORA-27154: post/wait create failed

ORA-27300: OS system dependent operation:semget failed with status: 28

ORA-27301: OS failure message: No space left on device

ORA-27302: failure occurred at: sskgpsemsper

 

 

What exactly is this error?

I checked ORACLE_HOME and oradata path,they are 90%(approx)
Oracle Version:-  9.2.0.6.0

 

Alert log shows following error repetitively:-

ORA-27154: post/wait create failed

ORA-27300: OS system dependent operation:semget failed with status: 28

ORA-27301: OS failure message: No space left on device
