Description Gowrishankar Rajaiyan 2013-07-15 10:03:08 UTC
SELinux is preventing /usr/sbin/glusterfsd from 'read, write' accesses on the chr_file fuse.

*****  Plugin catchall (100. confidence) suggests  ***************************

If you believe that glusterfsd should be allowed read write access on the fuse chr_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep glusterfs /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp

Comment 1 Niels de Vos 2013-07-15 15:38:00 UTC
There have been some improvements with the update related to bug 980683, but I do not think that access to /dev/fuse was included there.

/usr/sbin/glusterfs (a symlink to /usr/sbin/glusterfsd) is the client side process that accesses /dev/fuse. This behaviour should indeed be permitted.
