How can my RAID 5 array get visible again ?
(1/1)

Hi all,
I'm having an issue : the NAS has lost my RAID array (RAID 5 over 3 disks) but I know it is OK as I still can connect on the box in SSH and scan the disks :
--- Quote ---/ # mdadm --examine --scan
ARRAY /dev/md0 level=raid1 num-devices=3 UUID=ebdd7a6b:9e1cbf5c:79f0c3a3:96a18951
ARRAY /dev/md/1 level=raid5 metadata=1 num-devices=3 UUID=603e7452:dd806ac8:1c3daac7:9671e5ca name=1
--- End quote ---
but the system don't see my data array :
--- Quote ---/ # cat /proc/mdstat
Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4]
md0 : active raid1 sdc1[2] sdb1[1] sda1[0]
524224 blocks [3/3] [UUU]
unused devices: <none>
--- End quote ---
I have been able to assemble the array by recreating a /dev/md1 node (that is not created anymore at boot whereas /dev/md0 is) :
--- Quote ---/ # mknod /dev/md1 b 9 1
/ # mdadm --assemble --run --force --update=resync /dev/md1 /dev/sda2 /dev/sdb2 /dev/sdc2
mdadm: /dev/md1 has been started with 3 drives.
/ # cat /proc/mdstat
Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4]
md1 : active raid5 sdb2[0] sda2[2] sdc2[1]
5855285760 blocks super 1.0 level 5, 64k chunk, algorithm 2 [3/3] [UUU]
md0 : active raid1 sdc1[2] sdb1[1] sda1[0]
524224 blocks [3/3] [UUU]
unused devices: <none>
--- End quote ---
So I can mount my array, say on /mnt/test and access all my datas :
--- Quote ---/ # mkdir /mnt/test
/ # mount /dev/md1 /mnt/test
/ # whatever_I_want on /mnt/test
--- End quote ---
But the box web interface is still saying "No Volume Found" ...
Where is it stored in the config that the array is mount at boot ?
I forgot to give some details :
* my box is a DNS340L
* my firmware version is 1.07
* my hardware type is A1
Thanks in advance
