comment Two arrays have slightly different array size with same size disks/partitions, why?
I'm not sure if it's the write intent bitmap caused the difference, highly doubt it (because it will not take many spaces). I asked same question in linux.raid mailing list, Mikael Abrahamsson guess it's because of different data offset, which I believe it (but still no explanation for it). spinics.net/lists/raid/msg46175.html

comment Two arrays have slightly different array size with same size disks/partitions, why?
I just did a quick RAID creation test on loop devices in CentOS 6.5 (mdadm v3.2.x) and Fedora 20 (mdadm v3.3), found out that it's not the size overhead of RAID 6. Size of RAID 5 & RAID 6 are identical in same OS, but they are different between CentOS and Fedora. Test script: MAKEDEV /dev/loop; truncate -s 10M hdd5{1..5} hdd6{1..5}; for hdd in {1..5}; do losetup /dev/loop5$hdd hdd5$hdd; losetup /dev/loop6$hdd hdd6$hdd; done; mdadm -C /dev/md5 -l 5 -n 4 -x 1 /dev/loop5{1..5}; mdadm -C /dev/md6 -l 6 -n 5 /dev/loop6{1..5}; mdadm -D /dev/md5; mdadm -D /dev/md6

@Ouki, you mean the metadata size overhead, or the performance overhead?
