Thanks for clarifying the 2TB size. I'm still unsure of whether v1 allows for a recovery to continue after a restart. When I moved everything over to an LSI controller I had to use the system rescue cd which somehow marked my array as dirty. During the RAID recovery I had to reboot and it started the recovery over. It only takes 3 hours to rebuild the 3 TB drives, but if v1 offered this feature I might switch in the rare case I need it. I'm assuming enabling bitmaps could do the same thing for v0.90? However I've heard there is performance degradation of the array from this.
