첫 RAID5 어레이를 구축하는 중입니다. mdadm을 사용하여 다음 설정을 만들었습니다.
root@bondigas:~# mdadm --detail /dev/md1

그 동안 나는 다음 명령으로 짐승을 포맷하기로 결정했습니다.
root@bondigas:~# mkfs.ext4 /dev/md1p1
mke2fs 1.41.11 (14-Mar-2010)
/dev/md1p1 alignment is offset by 63488 bytes.
This may result in very poor performance, (re)-partitioning suggested.

"/ dev / md1p1 정렬이 63488 바이트만큼 오프셋됩니다."에 대해 어떻게해야하는지 잘 모르겠습니다. 디스크를 올바르게 분할하여 올바르게 포맷 할 수있는 방법.
