Subject: [Cluster-devel] [RFC 2/3] GFS2 rename race - lock reordering
Date: Tue, 12 Dec 2006 03:13:08 -0500 [thread overview]
Message-ID: <457E6494.6080806@redhat.com> (raw)
Currently GFS2 only obtains its rename global locks if the "source" is a
directory. This could result a deadlock if:
- Node 1 does "rename dir1/file-a dir2/file-b"
- Node 2 does "rename dir2/file-c dir1/file-a"
We'll unconditionally grab the global lock from now on unless the
"source" and "destination" are from the same directory.
