I've had the following BUG using lustre patchless client 1.6.3 on linux 2.6.20 (Fedora Core 6). This hard-locked the machine; I was unable to tell if there was a subsequent panic. This was while copying approx 2.7 TB from ext3 to lustre; it had copied about 2.6 TB; I haven't verified if the data made it across okay. There were a ton (> 1 M) of tiny files in this copy (which took about 60 hours over gigE); these cause a tremendous performance hit. This is not at all surprising, I just wonder if it's related to the bug.
I'm trying to get access to the lustre OSTs and MDTs and will post logs if they exist. I'm fairly new to lustre; are issues like this common when using a somewhat odd kernel?
