Chapter 7: Configure PSFS Filesystems 130

Unlock a Semaphore

To unlock a PSFS command-line semaphore, use this command:

$ psfssema -r <filename>

The command unlocks the PSFS command-line semaphore associated

with <filename>, which is a semaphore file created by psfssema -i. If other

nodes are blocked on the semaphore when psfssema-r is called, one of

the blocked psfssema -g processes will return successfully.

Delete a Semaphore

To delete a PSFS command-line semaphore, use this command:

$ psfssema -d <filename>

This command deletes the PSFS command-line semaphore associated

with <filename>, which is the name of a semaphore file created by

psfssema -i. It also deletes <filename> and <filename.pid>.
