I tried to add a 6th disk to a RAID-5 with raidreconf 0.1.2
Almost being done raidreconf aborted with the error message:
raid5_map_global_to_local: disk 0 block out of range: 2442004 (2442004)
gblock = 7326012
aborted
After searching the web I believe this is due to different disk sizes.

mdassembled was devise for this purpose.
create an /etc/mdadm.conf with

use different disks (vendor and type) having different geometries it is not
possible to have partitions of exact the same size. They match as good as
possible but some always have different

These require moving lots of data around, and need to be able
Hi,
I have 6 WD800Jb disk drives. I used 4 of them in a RAID5 (using the
whole disk - no partitions) array.
I have mixed them all up, and now want to get some data off the array.
How best to find out which drives were in the array?
Here are the partition tables (obtained using fdisk on OS X):

Hi,
I have many problems with RAID in kernel 2.6.10.
First of all, I have the md, raid1,... into the kernel, superblocks in
the RAIDs and Linux RAID autodetect as the partition types. Moreover,
I make an initrd. However, when the kernel boots, it doesn't recognize
the RAID disks:
md: raid1
Hmm.. for me:
smartctl -A -d ata /dev/sda
On my work machine with Debian Sarge:
smartctl version 5.32 Copyright (C) 2002-4 Bruce Allen

Smartctl: Device Read Identity

Just wonder what happens to the md sequence when I remove the original
raid arrays?
When I'm done will I have md0,md1 and md2 or md2,md3 and md4?
they will have the name you entered when you created the array.
after removing one array from the system all arrays will still

Was planning to adding a hot spare to my 3 disk raid5 array and was
thinking if I go to 4 drives I would be a better off as 2 raid1 arrays
considering the current state of raid5.
I just wonder about the comment considering the current state of raid5. What might be wrong
The only problem I have is related to bad blocks. This problem is common to
all RAID types. RAID5 is more likely to have problems.
