I see in libglusterfs/src/common-utils.c code that should cause gluster to observe values written to ip_local_reserved_ports (http://review.gluster.org/#/c/4131/) Since the fuse client uses bind(), when you run it as root it will attempt to bind to a port in the standard range allocated to root, being < 1024. This follows convention. So, you’ve probably got two options here, either mount as non-root or provide ranges you want the client to exclude in ip_local_reserved_ports. -t > On Apr 9, 2016, at 11:43 AM, Ryan.J.Wyler@xxxxxxxxxxxxxx wrote: > > Tom, this appears to be the same issue.
