The disk /dev/sde1 was rebuilding at nearly 40%. I think, this disk is

So it should be nearly synced to the both other clean devices. Can
someone help me, please?

In particular "Asking for help" - get the output for lsdrv on all drives.
I'm hoping it's a simple matter of re-assembling the array, and
restarting the rebuild. Try an explicit assemble, but DON'T use --force
unless advised by someone who knows more than I do -) and then either
the rebuild should restart automatically, or there are ways to restart it.
Just don't take the metaphorical hammer to try and force it to continue
- that's a sure way to wreck it.

Hi, thanks for reply. The output of lsdrv is:

I try to assemble, but it doesn't work:
[root@tsa lsdrv]# mdadm --assemble /dev/md0 /dev/sdd1 /dev/sdc1
/dev/sdb1 /dev/sde1
mdadm: /dev/md0 assembled from 2 drives and 2 spares - not enough to
start the array.
Is it importent to list the devices in correct order? I put a disk on
another computer for backup. This change the order of my devices. But I
have documented the correct order.
I didn't use --force at this time. I am current create backups from all
disks.
Cheers,
Martin
