Hi Avati, I'm experiencing complete system-wide hangs exactly as David has mentioned. > The discussion in this > thread is about those situations where the server (machine > hosting the > storage/posix volume) hangs the backend filesystem (verified by > kernel console logs) and that in turn results in the mountpoint > hang. That seems to be the case in Stephan's situation, yes, as we have evidence from reiserFS. What evidence have we in the ext3 cases? > While your symptoms are similar on the client side hanging, In the case of 144, my systems didn't hang. Maybe I was just lucky. Now that I have disabled read-ahead to workaround 144, I am seeing total system hangs. I also saw these hangs back before I used read-ahead (with 1.3). As I have said, it is like new FD's cannot be allocated, while those already open continue normally. I'm talking about regular ext3 mounts here, not glusterfs ones. > The discussion thread is about the situation where the server side > kernel misbehaves and results in glusterfs hanging. The two > actual problems are quite different. Perhaps, as I said, it may be coincidence, but when I ran with read-ahead, I didn't get any system hangs, just the core-dumps. Now, I don't get core dumps any more. I get system-wide hangs. Thanks, Jeff.
