I have been doing a lot of reading and re-learning about FUSE over the last week as I have been setting up GlusterFS in our dev environment. I cannot seem to get mmap() support to work. This is my set up: * RHEL5 / CentOS5 * FUSE 2.8.1 * GlusterFS 2.0.7 * RHEL5 kernel 2.6.18-164 (RHEL5.3, CentOS 5.3) * fuse.ko built from kernel source I continually get this when trying to use rrdtool to create or update RRD files on a shared front end: ERROR: mmaping file '/data/nagios/pnp/db/nagios-report/Test_2_-_192.168.79.132.rrd': No such device I can create and replicate files through scripts or vi/vim just fine on my two front end two back end cluster. Any ideas of what I might be doing wrong or if this is just a configuration / version mix that plain does not suppport mmap shared write access? Any pointers / tips / advice appreciated. Thanks, Max
