Data loss (1 reply)

hello,

I have encountered the data loss on mysql cluster. The cluster worked properly at the beginning. After it ran for some time, about last 2 days of data is lost suddenly.

I checked the log file of the mysql cluster. I cannot find any error message.


Any thoughts? thanks.
