I found the error in status> tasks>replication
"Error 49: The selected destination volume already contains replicated data.
If you are sure that you intend to choose this volume as a replication destination and OVERWRITE the existing data, you will need to clear the metadata on this volume first (CONFIGURATION -> volume manager -> Vol. replication -> Volume replication mode -> Clear metadata)."
I had tried to clear metadata for all LV at once, and apparently that didnt work, but when I cleared metadata one at a time, they were able to start replicating again. Thanks.
