(online) You can't. You'll need a downtime - the other node must become primary to access the data. It's going to be quite time consuming. You need to have a very clear picture of all the layers involved and how they access the data. Then, on a quiet day, unmount cleanly on the primary node, swap primary/secondary roles, test your data on the other node "somehow" - maybe fsck, maybe comparing md5sums, maybe comparing with backups - be creative, only you can decide how to do this in a meaningful way. If you do detect errors there, maybe you have a hardware problem worth investigating, or a very subtle and nasty bug somewhere . Otherwise, then just ignore the messages and live happily ever after. > I found explanation about "data getting modifying in flight" but no > "workaround" or everything on how I can avoid getting out of sync block. There's no solution, and hopefully there's no problem in the first place. Lionel.
