Is it possible to reseed a passive node from the active when circular logging is enabled? If the active did not have all the logs to bring the passive up to date by seeding will it fail? Thanks

You can't have circular logging and CCR together. It's just common sense that you need CL off in case you get congestion on the wire (or somewhere else) and log files on the active get stacked up.

Mark,

Thank you, Does this include the continuos replication circular logging CRCL that works on CCR clusters? My passive node needs reseeding, it doesn't even have database .edb's for the storage groups. The active node has circular logging enabled and looking at it has about the last hour of logs available to it. We do full backups so I have them on tape. Can you recommend a strategy for reseeding this passive node?

I will turn off circular logging. Backupexec is what we use for backups and it will auto truncate the logs after a backup.

You don't sound like you're in a state where you can "RE"-seed. You should destroy everything and re-do from scratch. Make sure you do not do any backups until the store has seeded and the logs have started going over and being played.

Just to clarify...
1. disable ciruclar logging
2. remove all files in my storage groups on the passive node
3. wait for it to reseed

Can I restore transaction logs from backup to the active node so that it has the ones it needs for reseed?

Mark can you comment on this... When I do test-replicationhealth on active all tests pass. When I do it on the passive for item SGCopySuspended I get this for all my storagegroups. Is this part of the same issue or something totally different?

'An RPC request to the MS exchange replication service did not return a CCR copy status for storage group 'triton\Users-ABC' The MS exchange replication service may be down.'
