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.
