Re: [Gluster-devel] fchmod glitch in 1.4 tla?

[Brent A Nelson]

I think I've found the culprit.  It was due to having mounted with noacl. 
cp -a attempts ACL operations, which fail wiht noacl mounts, but GlusterFS 
was apparently remembering that error and passing it as the return for 
fchmod.  With the filesystems mounted with acl support, the error is gone.

Here is the glusterfs log from "cp -a /bin/ls /beast" when the filesystems 
were mounted with noacl:
