June 8, 2004 To make this version of dmapi work with JFS you'll first need the JFS dmapi patch then add the corresponding jfs-dmapi-*-additional patch from this directory. The JFS dmapi patches can be found at IBM's website. Their patch will make JFS dmapi-capable, and will include a JFS-specific version of the dmapi core in fs/jfs/dmapi: http://www-124.ibm.com/developer/opensource/jfs/project/pub/dmapi/ Then, from this fs/dmapi/PATCHES directory add on the corresponding jfs-dmapi-*-additional patch. This patch will convert JFS to use this unified version of DMAPI. Then use the same libdm that you use with your XFS dmapi applications. You should have libdm from dmapi-2.2.0 or later. With these patches this unified DMAPI can manage XFS and JFS filesystems at the same time, however SGI has not tested JFS with DMAPI.
