Description Gobinda Das 2020-02-26 09:50:15 UTC

Description of problem:

While adding a gluster volume as storage domain, add a pre-check that the o-direct options are enabled on the gluster volume.

The following options need to be enabled on the gluster volume 
 performance.strict-o-direct on :Ensure that write-behind honours O_DIRECT flags.When this option is enabled and a file descriptor is opened using the O_DIRECT flag, write-back caching is disabled for writes that affect that file descriptor.
  * network.remote-dio off :filters _ O_DIRECT flags in open/create calls before sending those requests to server. Set to off to ensure all o-direct I/O is passed to brick

NA

Comment 2 SATHEESARAN 2020-06-17 02:54:44 UTC

Tested with RHV Manager 4.4.1.2-0.10.el8ev 

When performance.strict-o-direct option is not enabled on the gluster volume, 
then the attempt to use that volume for gluster storage domain in RHV Manager fails,
with the proper error that o-direct option is not enabled for storage domain
