SOLVED Error duplicate SN adding vdev to pool

[Beliall]

Hello,
Just add a 2nd HDD to the NAS
I would like to extend the 1st disk or add the 2nd through a vdev.
When i triés i for an error about a duplicate serial number
This duplicate is thé SSd (sda) divide in 2 partition.
1 for the os 1 for Storage.
I add the New disk (sdc) to the sdb pool.
Thats why i do not understand this message error

Is somebody understand why ?

My guess (and I'm forced to since you gave no hardware specs) would be that you're using some kind of USB enclosure with multiple disks, which makes you subject to something like this:

Hello,
I am not using any USB at all
Their are 3 drives in SATA on te mother board
All 3 on the same 6bps controler
1 SSD and 2 HDD
HDD are 2 seagate ironwolf and have 2 distinct SN in truenas

SATA Can be see as USB by truenas ?
As i said before the only eccentricity is on the SSD whith 1 partition for truenas OS and a seconde one for Storage use by qbittorent to dl faster

whole hardware configuration :
Motherboard :B85M-G43 4sata 6bps 2sata 3gbps
Proc:i3 4160
Ram: 2x8 1600mhz 2x4 1600mhz
500go SSD 2.5" sata3 sandisk
2x4to seagate ironwolf (no pro)

obligatory: your hardware is not recommended, and you have obviously somehow forced the OS disk to be allocatable. this is quite a ways outside any supported configuration. since I do not know how you forced this, I would first suspect that some part of this hack is affecting your other disks. I notice your screenshot seems to say you are trying to add sda to sda, which i would assume is why it says they are the same drive.

qbittorent will not "dl faster" on an SSD, all it will do is use up the SSD faster. download speeds are limited by your internet, not the disk. a slow HDD is perfectly capable of matching the vast majority of internet connections. also, since you have aparently hacked the OS and qbitorrent onto the same SSD, what you are doing is burning your system drive faster for negligile to zero benefit.

the first thing I would say to do is to redirect your qbittorent to the HDD, backups your config, nuke the SSD, reinstall with a supported boot configuration, restore your config file, and then see if you still have duplicate serials/drives.

qbittorent to dl faster

Not necessarily "faster", but you might want to read this if you want to continue using bittorrent on ZFS:

Workload Tuning — OpenZFS documentation

openzfs.github.io

In the direction of your issue... you got where you are via CLI, so that's how you're going to have to get yourself out of it...

You won't be able to use the GUI to manipulate pools/disks that are partitioned.

It's also not a good idea to have more than one partition on the same disk as a member of the same pool... technically can be done, just not great, hence the GUI stopping you.

Hello
Thank's for your answer

I read this sheet :https://www.seagate.com/files/www-content/datasheets/pdfs/ironwolf-18tb-DS1904-20-2111US-en_US.pdf
I got the 4to HDD
I understand a max speed of 180MB/s
My internet connection is over 1GB/S that's why i tried to use the SSD

And why Os and storage and the same SSD? Because its a 500go one ans apparently the OS don't need it so i gave it 200 and keep 300 for storage.

Regards,

Hello,
I will read your link with attention.
I used this method :https://youtu.be/Hdw1ELFaZH8
I understand the GUI don't let me do what i want.
I will dig a little more to try to do it in commande line, if i can't i will follow all your advise et go back to a "normale" configuration

Regards

Are you sure your internet connection is 1 GBytes/sec? Or it is 1 Gbits/sec?

1 Gbits/sec = 125MBytes/sec

Understand your Internet Speeds - Megabits vs. Megabytes

OH
Connection speeed is 1Gbits and HDD is 128 MBytes , so i don't need to use the ssd.
Crystal clear THX

Otherwise i add my second HDD to my HDD pool with : zpool add -f HDD1(poolname) /dev/sdc(hdd2)

All seems to be working.
I will follow all your kind advises and came back to normal setup as soon as possible.

Thank's

Anything you do from the command line will not persist on reboot or update, since it's not stored in the sqlite configuration database

Use the webGUI

Not correct (although good general advice).

Operations carried out on pools with tools like zfs and zpool will absolutely be permanent as those operations aren't configuration of TrueNAS and are rather settings made to the ZFS properties of the pool itself.

That's not a general recommendation to use the CLI, but a clarification that using the CLI in some cases will impact the system permanently.

In the case of this thread, that's already something that has happened, so he will need to continue to use CLI to work the situation out.

I tried several reboots and shutdowns
The new HDD is still in the pool

My last interogation is,does it working as i expect it works
I have a pool with two HDD, no mirroring only storage.
The first was pretty full, less than 10% available before i had the second one.

The first HDD will stay full or will the system balance the storage through the pool ?

Regards,

PS: im a bit sad to be on the wrong way with the use of comand line, it was not obvious for me :/

 

[HoneyBadger]

The first HDD will stay full or will the system balance the storage through the pool ?

It will "rebalance" over time through new writes or updates to existing data only. There is no "background rebalance."

In regards to your initial question about duplicate S/N - please check in the BIOS of your motherboard that the SATA ports are set to AHCI mode. If they are set to "RAID" or a similar mode of software/fake RAID it may interfere with the ability of the kernel to see the serial numbers.

 

[Beliall]

Hello HoneyBager
Yes it's on AHCI and thank's for your answer about the "rebalance"
I think twe have finish with this topic

Thank's you all !
