Subject: Boot fails from one of the drives cos it's not an ext4 filesystem.

Hello,
I have /dev/sda and /dev/sdb in RAID1.
I've discovered that I can boot from partition /dev/sda1 but not from
/dev/sdb1.
Apparently, both disks have equivalent partition tables:
# sfdisk -l /dev/sda
Disk /dev/sda: 121601 cylinders, 255 heads, 63 sectors/track
Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting
from 0
Device Boot Start End #cyls #blocks Id System
/dev/sda1 * 0+ 60- 61- 487424 fd Linux raid
autodetect
/dev/sda2 60+ 7841- 7781- 62499840 fd Linux raid
autodetect
/dev/sda3 7841+ 121601- 113760- 913773568 fd Linux raid
autodetect
/dev/sda4 0 - 0 0 0 Empty
# sfdisk -l /dev/sdb
Disk /dev/sdb: 121601 cylinders, 255 heads, 63 sectors/track
Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting
from 0
Device Boot Start End #cyls #blocks Id System
/dev/sdb1 * 0+ 60- 61- 487424 fd Linux raid
autodetect
/dev/sdb2 60+ 7841- 7781- 62499840 fd Linux raid
autodetect
/dev/sdb3 7841+ 121601- 113760- 913773568 fd Linux raid
autodetect
/dev/sdb4 0 - 0 0 0 Empty
But /parted/ tells me a different story.
This is the culprit: /dev/sdb1 is not known as ext4, as it should be.
# parted -l
Model: ATA ST1000DM003-9YN1 (scsi)
Disk /dev/sda: 1000GB
Sector size (logical/physical): 512B/4096B
Partition Table: msdos
Number Start End Size Type File system Flags
1 1049kB 500MB 499MB primary ext4 boot, raid
2 500MB 64.5GB 64.0GB primary raid
3 64.5GB 1000GB 936GB primary raid
Model: ATA ST1000DM003-9YN1 (scsi)
Disk /dev/sdb: 1000GB
Sector size (logical/physical): 512B/4096B
Partition Table: msdos
Number Start End Size Type File system Flags
1 1049kB 500MB 499MB primary boot, raid
2 500MB 64.5GB 64.0GB primary raid
3 64.5GB 1000GB 936GB primary raid
What would be a recommended way to fix this issue?
Thanks
