Hi, The device reported like this : $ blockdev --getss --getpbsz --getiomin --getioopt /dev/dm-3 512 4096 4096 0 Then, the sector size should be 512. Don't know why it can be 4096. :( I will try to backup them and reformat. Any suggestion for formating on raid-10 array? The device is 4 x 1TB drives.
