[Gluster-devel] race condition in 3.5.0qa3?

[Emmanuel Dreyfus]

My test fails on that:
cd /gfs351/manu/usr/src/obj/tooldir.NetBSD-6.1.2-i386/include/nbinclude && rm -f machine &&  /gfs351/manu/usr/src/obj/tooldir.NetBSD-6.1.2-i386/bin/i486--netbsdelf-nstall -l s -r i386 machine
i486--netbsdelf-install: machine: rename: Operation not permitted

Here is the client log:

Redoing the operation works fine, I therefore suspect a race condition: 
machine is not yet removed when rename(2) is attempted again 

Perhaps unrelated, but my brick log is filled with warnings:
[2013-12-17 04:40:30.360757] W [server-rpc-fops.c:2302:server_inodelk_resume] 0-/export/wd2a: frame 0xba7079fc, xlator 0xb9e52018
Or this:
