[Migrated from savannah BTS] - bug 25910 [https://savannah.nongnu.org/bugs/?25910]
Wed 18 Mar 2009 09:45:24 AM GMT, original submission by Krzysztof Strasburger <strasbur>:

Trying to mount the glusterfs volume (replicated on 13 nodes,
if it matters) results in lockup of every process trying to
access the newly mounted /usr directory. The mount program returns
success, but there are no signs of client connection in the
server logfile (monitored with tail -f during mounting).
Trying to umount /usr immediately after mounting ends with "/usr
is busy". Glusterfs and libfuse are compiled with --prefix=/
and monitoring the mounting process with strace -f indicates no
access to files in /usr, except of early (and successful) runs
of sed and grep. The same volume can be mounted without problems
on "less important" directories. Is it a glusterfs problem
or a general fuse issue? BTW, the same problem occurs with
2.0.0rc2 (earlier versions not checked).

I'm able to mount /usr with glusterfs-1.3.12, but it works for
a while only and lockup occurs later at a random moment. So,
the problem seems to be glusterfs related and probably 2.0.0
exposed an older bug.
