An excerpt from dmesg:

md: Autodetecting RAID arrays.
md: Scanned 2 and added 2 devices.
md: autorun ...
md: considering sdb1 ...
md:  adding sdb1 ...
md:  adding sda1 ...
md: created md1
md: bind<sda1>
md: bind<sdb1>
md: running: <sdb1><sda1>
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

Is it OK that kernel tries to mount an ext4 raid as ext3, ext2 first?
Is there a way to tell it to skip those two steps?

Just in case:

/dev/md1                /               ext4            noatime         0 1

TIA.
