Hard Disk Does not exist

[pwilson]

Thanks Patrick. I noticed some other posts about people a little bit confused about storage pool/volume/raid new logic.

http://www.qnap.com/en/index.php?lang=en&sn=9384 is trying to explain how everything articulates itself....

Creating two raid within 8 disk storage pool will really decrease the available storage size so I guess I will probably keep one Raid only.

Actually I had a look at this page "How to completely upgrade your NAS from QTS 3.8 to QTS 4.0"
http://www.qnap.com/en/index.php?lang=en&sn=9500
Obviously when I upgraded from 3.8 to 4.0 then 4.1 I never did anything special so I guess I have a legacy volume now. This may be the reason of the problems I had recently since my volume was not recreated properly unders 4.0 or 4.1. (by the way the rebuilding was completed properly yesterday). I am ready to start from scratch with the proper structure (storage pool->RAID->volume) but I was wondering about how to do it in details. It says to remove the disks physically to do a full reset. That mean recreating all users and so on... That is more work than I expected. Is there a way to avoid this physcial removal part ?
Thanks again as you really made me understand more about 4.0/4.1 and guide me in the good direction !

Nothing obvious about it. This is why I've kept asking for more information. Anyway, you've put yourself in a corner, until you are actually using Storage Pools, you can't do much. (I'm in the same boat. I have ordered 4 new drives for my TS-470 Pro, but they still haven't arrived. Right now I'm copying the configuration files for all my installed QPKGs off the NAS, so that I'll still be able to consult them once I setup my NAS again on the new drives.

When you say "Nothing obvious about it" for me it does really mean it is complicated. I have looked at different posts and it not obvious to see any benefits with these storage pools unless you really manage huge quantity of disks. In my case I cannot connect extension to my NAS anyway so I guess in reality it will not change anything except the fact that I need to do it in order to run properly the 4.1 firmware....
Thanks for your help during this post !

Well, not yet.

Hello
Do you think it will be possible in the future ? Is there any slot available in the x69L model ?
Thanks

Hi Patrick
I finally understand what happened to me 2 weeks ago and I realised that other people had the same issues in the post called

2 Disks are missing after restart
http://forum.qnap.com/viewtopic.php?f=25&t=88330

Because the restart function is not working properly, disk1 and disk2 are considered as not here, the rebuild starts... If I do a shutdown and a start with pushing the button physically or wake up pan, the disk are here ! There is obviously a problem with the restart function of my NAS. I have to do a 2 steps shutdown/start to make sure all my disks are read properly (green light on each disk).
Now to avoid a rebuild I wanted to ask you if there was a way to tell the NAS not to do anything if one or two disk were missing ? Is it possible to have the NAS not to rebuild automatically ?
This seems to be a serious bug.... at least for my model. Is there something I am doing wrong here ?
Thanks in advance for your help

Avoiding the physical removal part is easy enough.

(You can erase the partition tables on all your drives with a single command with the drives still inside the NAS):

Code: Select all

dd if=/dev/zero of=/dev/sd[a-h] bs=512 count=1

As for doing this properly, no there is no way of avoiding starting from scratch. SMB Firmware can not expand "Legacy" volumes. Check out badly titled QNAP Tutorial: How to completely upgrade your NAS from QTS 3.8 to QTS 4.0 for instructions for this task.

Hi Patrick
It is more about the issue with the restart function in1 steps versus the shutdown/restart in 2 steps that I wanted to know your opinion.

Hi Patrick,
I have a same problem with my QNAP, suddenly 2 disks not exist (disk 3 and 4) so I can't access my data on the storage pool.
I am using TS-1079 with RAID 6 and 8 disk. all disks are WD10EFRX-68PJCN0. I am using firmware 4.3.6.1446 Build 20200929.
Here are some result when I try SSH into QNAP :

Could you please advise me, what should I do, thanks.

Ibay.
