[Gluster-devel] QEMU (and other libgfapi client?) crashes on add-brick / replace-brick

Thu Aug 29 15:27:08 UTC 2013

Sorry for the delayed response... Well, I've just done a git pull (master
branch, now @ 3a3441e) and apparently the fuse mount problem has been
solved (can't figure out which commit exactly did it).

Still not sure about the replace-brick + libgfapi thing. I will get you
updated, thanks for now.
