boinc SEGVs if running on gluster/fuse filesystem

[romw]

I was having a problem running the boinc client on a CentOS 5.5 (64 bit) machine in that it would segfault while running the underlying application (observed with seti@home, einstein@home, lhc@home). At first I thought it was the 32/64 bit issue discussed elsewhere, but it continued after all the appropriate 32 bit libraries were installed.

Eventually I tracked it down to keeping the boinc/project files on a glusterfs filesystem (see http://www.gluster.org/). Note that glusterfs uses fuse.

Once I moved the boinc files to an ext3 filesystem, everything worked as expected. Even if this is not fixed, it is worth describing in the linux installation notes.

I have seen other oddities with glusterfs (which is probably due
to its fuse nature), in particular programs that call setregid(2).

FUSE has evolved since this report. This might or might not be an issue still. If it is please open a new issue.
