Hi Nicolas Martin,
I just got my new disk and plugged it into the NAS waiting it finish
RAID 5 rebuild.
Here is what I found:
* The OS itself will create 4 RAID1 to used for the OS , and the RAID5
of your data it should be /dev/md1
Here is the diagram in text version: (You may need to copy them into
a txt to make it looks normal.)
+---------+ +---------+ +---------+
| | | | | | /dev/md9 RAID1

Table Summary:
/dev/md9 RAID1 (sda1 sdb1 sdc1 ;543MB each) /mnt/HDA_ROOT
/dev/md256 RAID1 (sda2 sdb2 sdc2 ;543MB each)
/dev/md1 RAID5 (sda3 sdb3 sdc3 ;990GB each) PV:/dev/md1
VG:vg288 LV:lv1
/dev/md13 RAID1 (sda4 sdb4 sdc4 ;543MB each) /mnt/ext
/dev/md322 RAID1 (sda5 sdb5 sdc5 ;8544MB each)
As you could see , my data is under /dev/md1 RAID5 , for others they
are the RAID1.
Hope these could help you a little.
