我打算创build以下RAID 1：
Partition Size Filesystem / 20GB ext4 /boot 500MB ext4 swap 2GB swap /backup 10GB ext4 /opt all free size ext4 我有triyng这个configuration：
di partman-md/device_remove_md boolean true di partman-auto/method string raid di partman-auto/disk string /dev/sda /dev/sdb di partman-auto/expert_recipe string \ multiraid :: \ 10000 5000 20000 raid \ $primary{ } method{ raid } \ . \ 200 512 500 raid \ method{ raid } \ . \ 2000 512 4000 raid \ method{ raid } \ . \ 10000 512 15000 raid \ method{ raid } \ . \ 10000 10000 1000000000 raid \ method{ raid } \ . di partman-auto-raid/recipe string \ 1 2 0 ext4 / \ /dev/sda1#/dev/sdb1 \ . \ 1 2 0 ext4 /boot \ /dev/sda2#/dev/sdb2 \ . \ 1 2 0 swap \ /dev/sda3#/dev/sdb3 \ . \ 1 2 0 ext4 /backup \ /dev/sda5#/dev/sdb5 \ . \ 1 2 0 ext4 /opt \ /dev/sda6#/dev/sdb6 \ . di mdadm/boot_degraded boolean true di partman-md/confirm_nooverwrite boolean true di partman-md/confirm boolean true di partman-partitioning/confirm_write_new_label boolean true di partman/choose_partition select finish di partman/confirm boolean true di partman/confirm_nooverwrite boolean true
该设置显示RAIDconfiguration错误，并要求我检查系统日志文件。
你可以帮帮我吗？
谢谢！
