The RAID array is offline.
Disk 1 is not working but the NAS was working but it got in a confusion and would no longer boot.
So, I started without disks, added disks and ran the following commands and got the following response.
config_util 1
storage_boot_init 1
cat /proc/mdstat
md4 : active ….
md9 : active …
What do I do next? will "reboot" be sufficient or do I need to issue another command?
This is a QS419U II
Thanks!
I can totally relate to how you're feeling right now - been there a few times myself 😞
So ... First and foremost, I'm not a QNAP expert, I'm just sharing in thus forum what I figured out myself here (as a reference for myself).
Now, in your case, it could be that the array is damaged since you removed all disks and reinserted them. So keep that in mind.
I'd even recommend contacting QNAP support. I'm very hestitant myself when it comes to that, but the few times that I did contact them, they proved very helpful!
Now if you'd rather try some things yourself, then be aware that you may loose all data - and maybe you've already lost it by removing the disks. On the flips-ide: I've seen the RAID arrays (depending on the RAID level) being very resiliant.
Now back to trying things yourself:
This would be a gamble, but I'd shutdown the NAS and re-insert the original disks in the original order while the NAS is powered down.
Next step is to boot it again and once the boot completed, it should show the array again, just in a degraded state, since one disk failed - if I understood correctly. When this shows, you can eject the failing disk (hot swap, so pull it out while the NAS is powered on).
Now wait until the NAS shows the disk as missing.
This may take a minute or so! I remember that it took a bit longer than I had expected when I did this with my own array.
Once the NAS shows the disks missing, you can insert a replacement disk and the NAS will use it to rebuild the array.
Rebuilding will be indicated, and again this may take a minute before you see this happening in the web interface.
I recall that I had to be quite patient as well 😊
Hope this helps ...
