Hi all:
I'm using RDMA to do fs-metadata mirror between nodes. I
encountered a strange problem when the program was running:
Complete queue handler reported that the RDMA-Write operation failed,
the status of corresponding "struct ib_wc" is "IB_WC_RETRY_EXC_ERR".
The problem is encountered randomly. I don't know the meaning of this
error code as well as what to do next. Would anyone give me some tips?
thanks a lot.
Do you sync between the sides before closing the QPs?
Can you say it more detail? thanks.
If you try to send a message from local QP to a remote QP before the
remote QP is in RTR state (or after it was closed/transferred to the
ERROR state),
you may get RETRY EXCEEDED, because there isn't any QP in the remote
side that can accept your message (and send a response).
How do you connect the QPs? (And how do you close the connection between
them)
