RE: Expansion of round-robin fragmentation
Posted in 2008
I can answer my own question: It' a matter of seconds. I could do a test
with nearly productional environment.
But that implies the next question: Will the existing nearly full fragments
fill up regardless of the new fragments or will they freeze until the new
fragments have reached the same fill level as the old ones?
TIA, Reinhard.
