Hello:

I'm doing some testing of resizing a LVM-based DRBD partition.  I've
successfully resized the LVM, and then resized the partition via DRBDADM
(the partition is named part3)

drbdadm resize part3

I see the following on the Primary server, and everything is OK.

May  6 16:15:19 SERVER1 kernel: drbd4: drbd_bm_resize called with
capacity == 31457280
May  6 16:15:19 SERVER1 kernel: drbd4: resync bitmap: bits=3932160
words=122880
May  6 16:15:19 SERVER1 kernel: drbd4: size = 15 GB (15728640 KB)
May  6 16:15:42 SERVER1 kernel: drbd4: Writing the whole bitmap, size
changed

However, I see this on the Secondary server, and it's stuck in
WFSyncUUID:

May  6 16:15:18 SERVER2 kernel: drbd4: drbd_bm_resize called with
capacity == 31457280

May  6 16:15:19 SERVER2 kernel: drbd4: Resync of new storage after
online grow
May  6 16:15:19 SERVER2 kernel: drbd4: conn( Connected -> WFSyncUUID )

Seven minutes later, it's still in WFSyncUUID on the Secondary.

Am I missing a step?  Is something possibly configured wrong on my end?
Help? :)
