Subject: [PATCH 10/20] drbd: do not send P_CURRENT_UUID to DRBD 8 peer when
|
|
our disk fails
|
|
|
|
DRBD 8 does not understand P_CURRENT_UUID. Skip the peer in
|
|
diskfull_peers_need_new_cur_uuid() to avoid sending such a packet.
|
|
|
|
This is valid because the DRBD 8 peer generates a new UUID itself when
|
|
our disk fails.
|
|
|
|
This prevents failures of the form:
|
|
|
|
drbd res: Unexpected data packet Unknown (0x0044)
|
|
drbd res: peer( Primary -> Unknown ) conn( Connected -> ProtocolError ) pdsk( Failed -> DUnknown )
