I tried to add a replica of ROOT to a new server in my test environment.
An hour later, its status in iManager is still 'new', and DSTRACE says
"Error updating replica: failed, dib error (-785)."

What's the best way to recover from this? Since I already have three
other servers in the replica ring, is it safe (safe-ish?) to run
DSREPAIR -XK2 on the afflicted server?
