SOLVED Mirror-0 demirrored - remirror again

[Yves_]

Hi there,

Sorry for this post, but I did something really stupid when I tried to replace my slower 5400rpm drives with faster 7200drives.

The issue
I am stuck with the hot-pool having mirror-1, mirror-2, mirror-3, etc. but mirror-0 is gone rough. And its only this one drive da1 (gptid/61e38bde-fc24-11eb-a3a3-002590982d14) right now. As you can see here:

Code:

  pool: hot-pool
state: ONLINE
config:

        NAME                                            STATE     READ WRITE CKSUM
        hot-pool                                        ONLINE       0     0     0
          gptid/61e38bde-fc24-11eb-a3a3-002590982d14    ONLINE       0     0     0
          mirror-1                                      ONLINE       0     0     0
            gptid/308f2444-fcdd-11eb-a3a3-002590982d14  ONLINE       0     0     0

          mirror-2                                      ONLINE       0     0     0

errors: No known data errors

The goal
Add da0 back into mirror-0 together with (gptid/61e38bde-fc24-11eb-a3a3-002590982d14) which is da1 so I get back mirror-0.

The history (for those who are interested in it)
What I have done to create this issue was, I wanted to replace the 5400rpm drives with 7200rpm drives. So by mistake I somehow unmirrored da0 and da1...

Thanks a lot for your help

Cheers
Yves

Have a look at the process here:

Attach mirror drive to pool

Hi, purely from the curiosity of hobby'ism, I managed to pick up a Microserver Gen8 for a good price to replace my Rpi4+external USB drive. The setup atm is as follows: -Microserver Gen8 with Celeron 1610T (will upgrade to one of the Xeon E3's soon) -12gb ram -Running ESXi with Truenas Core VM...

That applies to the pool you have also, where you will "Extend" the disk on its own (gptid/61e38bde-fc24-11eb-a3a3-002590982d14) to make it into a mirror.

 

[Yves_]

maybe its me... but I only have Edit, Offline, Replace in this menu...

 

[sretalla]

Your pool thinks it's resilvering... maybe that's true.

You can't do another operation like adding a mirror while that's the case.

 

[sretalla]

Which version are you running?

 

[Yves_]

Yeah at that point some resilvering was actually running. Sorry, about that.

Currently running FreeNAS-11.3-U3.2

Update: Resilvering is done now. But this option is still not available. Might it be because of my "older" Version? CLI possible?

 

[sretalla]

That option is only there in 12.

You can do it in CLI.

Search for posts by me with zpool attach, mirror and gpart in them, I have described the CLI process several times already.

 

[Yves_]

Okay, I thought so.

Sorry, not want to get on your nervs. Just to make sure since it is a productive envoirment... You are refering to this post from you I think.

So the steps to take would be

Make sure nothing is on the disk
gpart destroy -F /dev/da0
Set the disk partitioning table to gpt
gpart create -s gpt /dev/da0
Create the swap
gpart add -s 2G -t freebsd-swap /dev/da0
and data partitions
gpart add -t freebsd-zfs /dev/da0
Get the gptid of the new zfs partition
gpart list -a da0
Attach the the hot-pool
zpool attach hot-pool gptid/61e38bde-fc24-11eb-a3a3-002590982d14 gptid/<from the command up for the zfs probably da0p2>
Check status if worked out
zpool status -v

Correct?

Update
I have already done it. WORKED FLAWLESS! @sretalla i owe you at least a beer! since you are swiss as well maybe I can once invite you for one! THANKS A LOT
