Re: [Gluster-devel] about afr

[Krishna Srinivas]

Nicolas,

When you restart the server logs indicating EBADFD is fine, AFR will
try the operation on the other server. When you have the situation
where the glusterfs client hangs can you attach gdb to the glusterfs
and mail us the backtrace?

gdb -p <pid of glusterfs>
type "bt" at the gdb command prompt.

Just want to confirm that glusterfs has not blocked at a system call.
(as we have non blocking io now)

Can you see if removing the performance translators helps? we can
narrow down to the problem translator in such case.
