Title: About HornetQ Shared Stores Describe the issue: Review chapter 17.8.1. About HornetQ Shared Stores and check whether following is correct: 1. HA with shared store journal on NFS is supported with journal type NIO and ASYNCIO. 2. HA with shared store journal on SAN/GFS2 is supported only with NIO jounal type. There are some warning/important paragraphs which is confusing, like: HornetQ supports shared stores on GFS2 on SAN, as well as high availability on NFSv4. The journal-type attribute must be set to ASYNCIO for these options, as NIO cannot be used for high availability. - here is bad that we say NIO is not supported for shared journal on NFS.
Closing. Information provided in my comment is out-of-date. This is no longer a problem in EAP 6.3.0 doc.
