I never used the whole disk in my raid, so maybe my procedure is not useful in this case, but i think if you create partitions, you should create the array using them, using the following command mdadm --create --verbose /dev/md0 --level=raid5 --raid-devices=5 /dev/sd[bcdef]1 --metadata 1.2 i can't recall where i see why to specify this metadata level but in my case the default was not 1.2 so i had to. When the rebuild is done and a filesystem set , run this command dd if=/dev/zero of=/some/dir/test.dd bs=4096 count=2621440 to actually test the performance of the raid. 2011/7/22 Pol Hallen <raid1@xxxxxxxxxxxxxx>: >> Why did you create partitions?
