Thread: NTFS RAID with MDADM: odd partitions reported by FDISK

hi,

problem recurrent , reproducible, has happened other users have reported far haven't had answer. problem happens when create raid array (no matter type) mdadm, , formatted ntfs mkfs or similar.

reference, want create raid1 volume 2 1tb drives formatted ntfs, works expected output of fdisk -l follows:

code:

disk /dev/md0: 1000.2 gb, 1000202101760 bytes  2 heads, 4 sectors/track, 244189966 cylinders  units = cylinders of 8 * 512 = 4096 bytes  disk identifier: 0x2052474d    doesn't partition table  selected wrong device.    device boot start end blocks id system  /dev/md0p1 ? 822447 240553456 958924038+ 70 disksecure multi-boot  partition 1 not end on cylinder boundary.  /dev/md0p2 ? 244156454 471478443 909287957+ 43 unknown  partition 2 not end on cylinder boundary.  /dev/md0p3 ? 28216909 28216910 5 72 unknown  partition 3 not end on cylinder boundary.  /dev/md0p4 330301441 330307927 25945 0 empty  partition 4 not end on cylinder boundary.

output palimpsest similar.

can see, appear wrong ntfs. ntfsfix doesn't complain , have done several consistency checks, none of has failed. confused , furthermore afraid might corrupt data.

can please clarify whether serious issue or confusing bug?

you're trying interpret contents of filesystem if partition table. software raid array created from individual partitions, not contain partitions, @ least not you've configured -- contains filesystem.

also, why put ntfs on linux software raid array? afaik, windows can't access it, using ntfs on asking trouble -- there's power failure or other minor problem, impossible correct it, since linux lacks ntfs maintenance tools. use linux filesystem, not ntfs, on array.
