Software RAID 5 problem

I've got a big problem with my raid 5 on my linux redhat machine. I'm testing my software raid 5 at the moment, so i thought by myself i pull out a disk and put it back in, but it turned out i pulled out the worng one. so after putting it back in i pulled out another disk.
Now when i boot my linux redhat i'll get an error like this:

an error accurred during RAID sartup
starting up raid devices : mdadm : /dev/md0 assemble from 3 drives

not enough to start the array
/dev/md0 : invalid argument
/dev/md0 : is nog a RAID0or liniear array

who helps me out here
I can login to a RAID REPAIR shell but don't know what todo

when i use the raid tools i'll get the following errors

lsraid -a /dev/md0
output: lsraid -mddevice [9, 0] /dev/md0 is offline: please specify the dis query.

mdadm --detail /dev/md0
mdadm: md device /dev/md0 does nog appear to be online

thnx in advance

Correcting myself here... Once you find out a partition that should be part of your raid set :

mdadm --examine /dev/hda4 (drive and partition here)

You'll get output something like this:

/dev/hda4:
Magic : a92b4efc
Version : 00.90.00
UUID : 45008a00:6ebc837c:c02320fa:8a15251d

Raid Level : raid1
Device Size : 47737024 (45.53 GiB 48.88 GB)
Raid Devices : 2
Total Devices : 2
Preferred Minor : 0

Update Time : Thu Mar 17 20:20:01 2005
State : dirty
Active Devices : 2
Working Devices : 2
Failed Devices : 0
Spare Devices : 0
Checksum : 2ae6c0a3 - correct

Number Major Minor RaidDevice State
this 0 3 4 0 active sync /dev/hda4

0 0 3 4 0 active sync /dev/hda4
1 1 3 68 1 active sync /dev/hdb4
sh-3.00#

Then you can assemble it via :

mdadm --assemble /dev/md1 /dev/hda4 /dev/hdb4
