How can I tell if a filesystem is mounted with Async I/O enabled?

[Timothy Czarnik]

The Oracle DBAs are asking me to verify that Asynchronous I/O is available and enabled on the Oracle database filesystems on our Suse 10.2 server. Is it just as easy as adding the mount option async in the /etc/fstab file? Also, once enabled is there a way that I can verify that it is enabled so I can show the DBAs?

Thanks in advance!

adding async as a mount option to the fstab entry should do the trick. then later when you do 'mount' it will show what options are active for all fs.

note as well, if you use 'defaults' option to mount single filesystem it may enable async access as well without explicitly reporting it in 'mount'.
check 'man mount' for your platform to be sure.
