Hi Rudy,
I was able to assemble the raid by stopping the array first, and
forcing the assemble.
I backed up most of my data now and I can breathe :)
Now I want to know which drive I should replace.
Here's what I got from dmesg :

I'm not sure what to think of this. Which drive is really dead? Or
were they simply synched but still usable?
Let me know if more information could help you to help me :)
Thanks!

Hi,
I'm new to this mailing list but I subscribed because of this
problem with my raid5.
I really don't want to mess this up and it was clearly suggested to
not rush things on the wiki. So I'm looking for help :)
My raid has been running great for a long time now but I think it
needs so serious maintenance.
I have a 4 disks raid 5 on ArchLinux, mdadm version 3.3.1.
First, the raid status :
/dev/sda:
1 1 0 0 1 faulty removed
/dev/sdb:
1 1 0 0 1 faulty removed
3 3 0 0 3 faulty removed
/dev/sdd:
Number Major Minor RaidDevice State
this 1 8 16 1 active sync /dev/sdb
0 0 8 32 0 active sync /dev/sdc
1 1 8 16 1 active sync /dev/sdb
2 2 8 48 2 active sync /dev/sdd
3 3 8 64 3 active sync /dev/sde
/dev/sde:
Number Major Minor RaidDevice State
this 0 8 64 0 active sync /dev/sde
0 0 8 64 0 active sync /dev/sde
1 1 0 0 1 faulty removed
2 2 8 16 2 active sync /dev/sdb
3 3 0 0 3 faulty removed
Obvisously the event count is wrong on 2 disks. One disk has been
gone for a long time now...
1 - First question : how can I safely assemble the raid to the
latest sync state? I don't want to mess this up.
2 - Does this mean my hard drives are dead, or simply desync?
Also I tried to force assemble :
mdadm --assemble --force /dev/md0 /dev/sda /dev/sdb /dev/sde

First:
- what information is in dmesg or kern.log, or whererever your distro
stores disk messages? Asking only for the relevant parts about the
disks :)
- Do you have any idea when the disks were kicked out?
- can you give the output of smartctl -a for each disk?
- output of cat /proc/mdstat?
The assemble you tried is probably failing because the raid is
assembled but not started. Doing a "mdadm -S /dev/md0" should take
care of that.
Cheers
Rudy
