Hi!
Due to a very bad idea/error, I zeroed my first GB of /dev/md0.
Now fdisk doesn't find any disk on /dev/md0.
Any idea on how to recover?
MfG,
Lars Schimmer

It largely depends on what is /dev/md0, and what
after RAID5 is
filled with data?
E.G. I setup a 9 disk SOFT-RAID5 with XFS and 3125669888 blocks level 5,
128k chunk, algorithm 2 [9/9] [U].
Speed is not really fast, I assume it could be faster.

Hi!
I´ve got a software RAiD5 with 6 250GB HDs.
Now I changed one disk after another to a 400GB HD and resynced the
raid5 after each change.
Now the RAID5 has got 6 400GB HDs and still uses only 6*250GB space.
How can I grow the md0 device to use 6*400GB?
MfG,
Lars Schimmer

mdadm --grow is your friend.
Oh, damn, right. I was focussed on --grow to add a new HD to the RAID
But isn´t there a switch to grow to max possible value?
Do I always have to search
