DRBD works well fistly. ( both primany node and seconday node works well.) But somehow, the seconday machine has disk problem and in the /var/log/messge of the primary node, has below info: +++++++++++++++++++++++++++++++++ Nov 13 00:12:30 cs-mdc-b kernel: drbd0: pdsk( UpToDate -> Diskless ) Nov 13 00:12:30 cs-mdc-b kernel: drbd0: Creating new current UUID Nov 13 00:12:30 cs-mdc-b kernel: drbd0: Got NegAck packet.

(the write operation is like this: call linux api "msync", using MS_SYNC mode.) Would you help to explain this ? Is this a bug of DRBD ? or I configured wrongly ?
