[DRBD-user] Online Verification

[mailtolouis2020-forum at yahoo.com]

Hi Dan,

Thanks for the reply.

Another question, is there any different where I run the drbdadm verify <resource> ? Or I should always run on secondary server?

Regards
Louis

>No, on the secondary do a drbdadm <resource> disconnect and then a reconnect. The “reconnection” starts the resync. Note, if you are dual primary, it won’t resync. That would require demoting a node to secondary, disconnect, connect, primary.
