Clients must replay opens on the MDS if "done writing" is still pending to notify the new MDS that this file is volatile. Does it matter whether the client already sent "close" to the previous MDS instance? Does it have to send "close" again? 2. I assume "done writing" is only sent after stripe updates have been committed, not just executed so that cached SOM attributes are not dependent on the client still being around to participate in recovery if an OST fails. Is this correct? -- Cheers, Eric
