Well, I am pretty sure that patch solves one hw limiting issue, so there is probably something left for big arrays or for some specific configuration. If you want to help, please send me (not to list) tar output of lvmdump command (when cryptsetup active; lvmdump is part of lvm2 package). Also, I forgot that there are some patches not yet in upstream, specifically http://www2.kernel.org/pub/linux/kernel/people/agk/patches/2.6/editing/dm-merge-max_hw_sector.patch and maybe http://www2.kernel.org/pub/linux/kernel/people/agk/patches/2.6/editing/dm-crypt-fix-write-endio.patch (all in latest -mm tree) Also is there the same problem when running on some small raid array (e.g. 3x500G in RAID5) on on the same hw ? (Please, if you can, reply directly to my mail too, or alternatively report this problem through bugzilla, thanks.)
