dmesg的摘录:
md: Autodetecting RAID arrays.
md: Scanned 2 and added 2 devices.
md: autorun ...
md: considering sdb1 ...

raid1: raid set md1 active with 2 out of 2 mirrors
md1: detected capacity change from 0 to 1500299198464
md: ... autorun DONE.
md1: unknown partition table
EXT3-fs (md1): error: couldn't mount because of unsupported optional features (240)
EXT2-fs (md1): error: couldn't mount because of unsupported optional features (240)
EXT4-fs (md1): mounted filesystem with ordered data mode
内核尝试先将 ext4 raid 挂载为 ext3, ext2 是否可以?
有没有办法告诉它跳过这两个步骤?
# mdadm --detail --scan
ARRAY /dev/md/1 metadata=0.90 UUID=56851215:5dca6eee:776c2c25:004bd7b2
# grep dev/md /etc/fstab
/dev/md1 / ext4 noatime 0 1
TIA。
