Would it be > possible to read bitmaps from all physical drives at the same time? Certain non-trivial amount of work is need to be put into "parallel" fsck then. I have idea of a "hack" that might work, though ;) fsck -a may not close the device until it gets mounted (or some timeout passed). Then mounting will get bitmaps out of the cache or at least I hope so. Need to do some experiments. Bye, Oleg
