[Gluster-devel] stat-prefetch unstable

I started up my larger glusterfs (16 disks on one node mirrored to 16 
other disks on another node, all unified), and noticed that stat-prefetch 
still has some issues.

This filesystem had a bunch of /usr copies and copies of my home 
directory.  A du was not fully successful (it would die prematurely,saying 
that several directories were not found, even though they were clearly 
there).  Also, when I started multiple 'rm's on both nodes, the 
glusterfs processes would die within a few minutes.  I remounted and 
tried again many times.

When I removed stat-prefetch from my configuration, the removes ran to 
completion, so it seems solid without stat-prefetch.

It looks like stat-prefetch dies under heavy meta-data stress...
