IBM General Parallel File System for AIX: Data Management API Guide

Events implemented in DMAPI for GPFS

Following are the events, as defined in the XDSM standard, implemented in DMAPI for GPFS :

File System Administration Events

• mount
• preunmount
• unmount
• nospace

Namespace Events

• create, postcreate
• remove, postremove
• rename, postrename
• symlink, postsymlink
• link, postlink

Data Events

• read
• write
• truncate

Metadata Events

• attribute
• destroy

Pseudo Event

Note:

GPFS guarantees that asynchronous events are delivered, except when the GPFS daemon fails. Events are enqueued to the session before the corresponding file operation completes. See Chapter 5, "Failure and recovery of Data Management API for GPFS" for further information on failures.
