Feature: Provide support for native linux AIO in glusterfs
Reason:
"The POSIX asynchronous I/O (AIO) interface allows applications to initiate one or more I/O operations that are performed asynchronously (i.e., in the background). The application can elect to be notified of completion of the
I/O operation in a variety of ways: by delivery of a signal, by instantiation of a thread, or no notification at all."
This needs re-editing, as this is the output of man aio.
Result (if any):

Hi Shishir, Could you please provide libaio support information in Doc Text field? Thanks, Divya Hi Shishir, Based on your inputs, I have come up with the following content for libaio support: option: linux-aio Description: This option enables support for native Linux AIO (Asynchronous I/O) in Red Hat Storage. This Linux AIO interface allows applications to initiate one or more I/O operations that are performed asynchronously. This improves the responsiveness of glusterfsd process. Default Value: enable Available Options: enable | disable Please review and let me know if it requires any change. Thanks, Divya I have documented "linux-aio" option in Tuning Volumes section and updated guide is available at: http://documentation-devel.engineering.redhat.com/docs/en-US/Red_Hat_Storage/2.0/html/Administration_Guide/chap-User_Guide-Managing_Volumes.html#sect-User_Guide-Managing_Volumes-Tuning Hi Divya, In your "comment 3", you mentioned that the default value for linux-aio as "enable", but in the documentation I find the default value as "disable". I hope either of the one should be incorrect. I was trying to check the default value of linux-aio option, but I could not able to find that. Please add suitable comment, for me to verify this bug Got info from Divya, that by default linux-aio is disabled. Moving this bug to VERIFIED state |
