Technical Notes<br />

Mutexes, semaphores, condition variables, and read/write locks set this error<br />

condition to indicate that a lock is held.<br />

The symbolic name for this error is EBUSY, errno=16.<br />

device busy<br />

Cause<br />

You eject cdrom and you receive the message device busy. This could be the<br />

result of a number of problems. Below is a list of things that you can check and do to<br />

allow ejection of the cd from the device.<br />

Action<br />

Ensure that the current directory is not somewhere in the CD:<br />

% cd<br />

%eject cdrom<br />

Step B: As root<br />

# cd /etc/init.d<br />

# ./volmgt stop<br />

# eject cdrom<br />

If this works<br />

# ./volmgt start<br />

If this does not work go to step B.<br />

Step C: As root<br />

# fuser /cdrom<br />

Kill any processes that you feel that you have already terminated. A note of caution:<br />

If this is a nfs-mounted cdrom and there are other users who access this drive, make<br />

sure you know what process you are killing and why.<br />
