Replication Issue

[stefanb]

Hi,

I've a question about replication and a possible problem I have:

Snapshot was taken, used 77MB space.
Replication task succeeded
Snapshot on 2nd system exists, used space 0MB!?!

The logs are stupid - whats going on there?

Code:

Did you figure this out?

Hi,

repliaction is working.
Because I only need snapshot for replication, I did the following steps:
Delete all snapshots on push
Delete all snapshots on pull
Delete all snapshot tasks
Delete all replication tasks
Create new snapshot tasks on push
Waiting for first snapshot to be done
Create a new replication task, with "Initialize remote side for once. (May cause data loss on remote side!)"
After replication starts (it sends all the data to pull - 5TB) and is still running, I disabled it, cause transfer is longer than the interval of snapshots
After replication finished, I enabled the task again

Works now for 4 days

Cause I didn't need snapshots, only replication, I fight with myself to switch to rsync.
