Hi Rob, Vikrant, You can apply this patch. It should fix the build errors.. Actually, it turns out that the assert was also buggy in one other place.. So it was good that this came up. As regards to mmap-racache: I havent seen any problems with it since it is primarily triggered only for executables being run off pvfs2 volumes. That does not mean there are no bugs in it, but it would be great if someone can report any bugs if they stumble across it with that code path. thanks, Murali

That code (post_io_readahead_request) is protected by an ifdef (#ifdef USE_MMAP_RA_CACHE). did you configure pvfs with --enable-mmap-racache ? The short-term workaround might be to re-run configure without that option. It's definitely a bug on our end that we don't even compile when mmap-racache is selected, but be warned that even if we fix the compile issue, there were at one time some bugs with the mmap readahead cache. ==rob -- Rob Latham Mathematics and Computer Science Division A215 0178 EA2D B059 8CDF Argonne National Lab, IL USA B29D F333 664A 4280 315B _______________________________________________ Pvfs2-users mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users
