Message-ID: <078f01ca8e31$22ff9f80$68fede80$@com> (raw)
Vitaly,
1. 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
