Same mdstat.log?

Do a full backup. Then do a factory install with all disks in place, and confirm that the RAID array is correct. Then reconfigure the NAS, and restore the data from backup.
A variant is to do the factory install with only the new disk in slot 1, and confirm that is ok. Then hot-insert the remaining disks one at a time.

Hi Stephen,
thanks for the reply.
I have copied the mdstat.log.
Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4]
md2 : active raid1 sda3[2]
2925544752 blocks super 1.2 [2/1] [_U]
md1 : active raid1 sda2[2]
524276 blocks super 1.2 [2/1] [_U]
md0 : active raid1 sda1[2]
4193268 blocks super 1.2 [2/1] [_U]
unused devices: <none>
I have booted the NAS after sync only with the new disk in slot 1 inserted and no data was available.
Another boot with only the old disk in slot 2 was showing all the data.
So I guess nothing's been copied.
Now the NAS is working only with the disk in slot 2.
I will try WD's Lifeguard software, but it's gonna take some time.
greetings
JJ

So disk 1 isn't in the array at all.
After you use the normal long nondestructive test with lifeguard, you should also run the full write zeros test. If both pass, then try inserting the disk back into slot 1 with the NAS running.

Ok, thanks for the suggestion. I will do so and let you know the result.
Normal test is running about 5 hours and then I will write the zeros.

The long test was running without errors, but I could not find a test to write zeros.
Status is as follows:
Personalities : [linear] [raid0] [raid1] [raid10] [raid6] [raid5] [raid4]
md2 : active raid1 sdb3[3] sda3[2]
2925544752 blocks super 1.2 [2/1] [_U]
md1 : active raid1 sdb2[3] sda2[2]
524276 blocks super 1.2 [2/2] [UU]
md0 : active raid1 sdb1[3] sda1[2]
4193268 blocks super 1.2 [2/2] [UU]
unused devices: <none>The volume is up but not redundant, disk 1 is as usual the problem.
Can you point out how to write zeros?

Click on "run tests" and then click on "erase" Choose the "full erase" option.
- JJNas24Oct 09, 2019Aspirant
Hi,
I have done the full erase.
After that i have inserted the new disk again in slot1, rebuild starts and ends with same problem.
Do you have another idea?
