drbd: Fix disconnect to keep the peer disk state if connection breaks during operation

2013-03-28T16:10:25+00:00

The issue was that if the connection broke while we did the
gracefull state change to C_DISCONNECTING (C_TEARDOWN), then
we returned a success code from the state engine. (SS_CW_NO_NEED)

The result of that is that we missed to call the fence-peer
script in such a case.

Fixed that by introducing a new error code (SS_OUTDATE_WO_CONN).
This one should never reach back into user space.

drbd: Implemented two new connection states Ahead/Behind

2011-03-10T10:34:46+00:00

In this connection mode, the ahead node no longer replicates
application IO. The behind's disk becomes out dated.

drbd: don't start a resync without access to up-to-date Data

2010-05-17T23:08:18+00:00

In case both nodes are "inconsistent", invalidate would
have started a resync anyways, without a chance to ever
succeed, just filling the logs with warning messages.

Simply disallow that state change,
re-using the SS_NO_UP_TO_DATE_DISK return value.

This also changes the corresponding error string to
"Need access to UpToDate Data" -- I found the
"Refusing to be Primary without at least one UpToDate disk"
answer misleading in some situations anyways.
