Though i could be wrong here , but what i understand is: After Roll back Scenerio:
A( Primary Snapshot rollbacked to time: say 12:10:00 PM) , B(Secondary Snapshot roll backed to time say 12:09:00 PM) Current time say : 12:30:00 PM Now A must have received acks(in the past of ofcource) from B between 12:09:00 to 12:10:00 PM , now at 12:09:01 B says i dont have the data which might have confused A as it must be saying saying that you have already acked me few data , then how can you say now that i don't have the data now.Hence the Error.This is just my thought.Or does DRBD support such scenario, if yes then that is awesome than as that prevent complete resynchronization of data. Anyways with DRBD Down , you can always get the data back from ZVOL snapshot(otr its clone) itself(assuming DRBD metadata doesnot contain actual data ?? ) On Tue, 2 Aug 2022 at 15:04, Roland Kammerer <roland.kamme...@linbit.com> wrote: > On Tue, Aug 02, 2022 at 02:54:02PM +0530, Chitvan Chhabra wrote: > > Unable to see the older thread.May Be it is just me.Request to share > older > > conversation as well please. > > we have an archive: > https://lists.linbit.com/pipermail/drbd-user/2022-July/026252.html > _______________________________________________ > Star us on GITHUB: https://github.com/LINBIT > drbd-user mailing list > drbd-user@lists.linbit.com > https://lists.linbit.com/mailman/listinfo/drbd-user >
