The logs please?
Comment 3 Shehjar Tikoo 2010-07-04 03:00:27 EDT
Anush, we have been running tera bytes of IO using iozone over nfs so if I have to fix this, I need those logs which I've asked for before. This does not look like a trivial bug because of the extensive testing the IO path in NFS is undergoing.
Comment 4 Shehjar Tikoo 2010-07-04 03:17:39 EDT
The one thing you need to try for reproducing this is by using the access-control translator. Its not there in this volume file. Please test with and without access-control to reproduce. Just another data point in helping fix it.
Comment 5 Shehjar Tikoo 2010-07-29 03:41:46 EDT
Not able to reproduce. Closing.
Comment 6 Anush Shetty 2010-07-29 03:57:40 EDT
I still got the crash with Alpha. Works now with Beta git
Comment 7 Shehjar Tikoo 2010-09-24 03:40:42 EDT
