I am wondering how fast the initial HAST sync normally is - I created these 4 HAST providers yesterday on 4 146 gig drives, and they still each have over 90 gigabytes 'dirty' today. The machines are powerful (dell r710) and are otherwise idle, and they are connected to the same gigabit switch. I can supply details about any part of the configuration if needed, but I just wanted to ask if you guys believe something is wrong here. I can't help but think, if the initial sync takes 24+ hours, then if I ever need to replace one of the servers, I will be without redundancy until the new server reaches 0 'dirty' bytes, correct ? Thank you in advance for any input, Best regards, Thomas Steen Rasmussen
