Ok so here's the situation. I've got 2 FreeNas Servers one primary and one offsite backup. I have DataSetA on Tank1 On the Primary Server. Everynight it automatically takes a snapshot and replicates to the Backup Server.
PrimaryServer/Tank1/DatasetA -----> BackupServer/Tank1/DatasetA
Works great pretty simple. However, now on the Primary Server I'm running out of pool space and I've created a new pool with extra disks that I want to Migrate DataSetA to(which i was just thinking of doing a local zfs send and zfs recv). So now I want to have the auto snapshots and replication look like this.
PrimaryServer/Tank2/DatasetA ----> BackupServer/Tank1/DatasetA
But I don't want to have to redo the replication from scratch as none of the data has changed(its just moved to new hard drives in the primary server) and the data link is long distance WiFi and I only get like 40mbps.
Is there some way for me to acheive this migration to new disks without transfering all of the data over to the backup server again?
