Is the Resync after cf forcetakeover -d a full sync or incremental

[FalkSchneider]

Hello,

when I have a switched of fabric attached Metro Cluster and I follow the procedure for so called split brain the Synch mirror between the source and target have to be mirrored and resynched. The command   

aggr mirror aggr0 -v aggr0(1) is used for this.

Now my question is, is this resynch a complete new resync or is this an incremental resync? If it is incrementall, what is the base?

Every info or document regarding this is appreciated, Thanks in advance.

Regards Falk

This really depends. If possible, it will perform incremental resync; the base is common aggregate snapshot on both plexes. If this is not possible, it will complaint and you will have to recreate mirror from scratch. This is described in Active/Active configuration guide.
