Great :-) > I wonder why the peer has smaller max bio size in the first place, though. Because the harddisk in the peer is connected to a 3ware/LSI 9750 controller which supports a max_hw_sectors_kb size of 128, only - while the harddisk in the primary is connected to an on-board controller supporting much larger values. (BTW: The 3ware/LSI raid controllers perform incredibly bad when used with fast SSDs due to this ridiculously low max_hw_sectors_kb - it seems they try to promote their overpriced "SSD support" add-on-dongle that way. I can only say that I'll never buy a 3ware/LSI controller again, because of that.) Regards, Lutz Vieweg
