Subject: [PATCH 02/20] drbd: improve decision about marking a failed disk
|
|
Outdated
|
|
|
|
Sometimes it is possible to update the metadata even after our disk has
|
|
failed. We were too eager to remove the MDF_WAS_UP_TO_DATE flag in this
|
|
case.
|
|
|
|
Firstly, we used the "NOW" states, so would mark our metadata Outdated
|
|
if we were a Primary with UpToDate data and no peers, and our disk
|
|
failed. Use the "NEW" states instead.
|
|
|
|
Secondly, do not consider peers that are disconnecting, because they
|
|
will not see that our disk state is Failed, and so will outdate
|
|
themselves. We do not want to outdate both nodes in this situation.
