Under what scenario would the overflow record not get written? You mean a power outage? Or what exactly?

Specifically, it's not safe to have overflow in hashed files because the overflow pointer and overflow data require two separate writes to disk. If a failover occurs when only one of the two writes has been completed, you'll likely end up with a corrupted file. I've eliminated this issue in our environment by keeping all hashed files sized to have no overflow and only using dynamic files for temporary report data. This probably isn't feasible in a lot of environments. -John -----Original Message----- From: u2-users-boun...@listserver.u2ug.org [mailto:u2-users-boun...@listserver.u2ug.org] On Behalf Of John Hester Sent: Tuesday, September 03, 2013 11:40 AM To: U2 Users List Subject: Re: [U2] REPLICATING DATA We've been using LifeKeeper from SIOS to replicate UV for around 10 years.
