gpart: geom 'nda1': Operation not permitted when adding 2nd disk to Opensense

[bx2]

Hello everyone,

I have the CWWK N100 and I'm looking to add another NVME drive into it just for redundancy as I have the spare drives.

I have been looking at these instructions (https://forum.opnsense.org/index.php?topic=32650.0) which seem simple enough but I'm getting hung up on the steps to copy the partition table.

Code Select Expand

"gpart backup ada0 | gpart restore -F ada1"
When I run geom list disk, I see both of my drives showing:

My opnsense is installed on nda0 but when I run the command to start copying the partition table, I get an error stating:

root@OPNsense:~ # gpart backup nda0 | gpart restore -F nda1
gpart: geom 'nda1': Operation not permitted
Now, nda1 (the new drive) may have been formatted and used in another random PC so I'm unsure if its an issue with formatting?

I don't think that it is related to formatting but I'm not entirely sure.

Has anybody else ran into this issue?

Can you try wiping the new drive first (sure you do it on the right device! Backup is always a good idea, of course):

As mentioned in OPNsense Forum: Formatting whole disk before installation, try destroy the disk and delete the first 1M of the drive:

Code Select Expand

gpart destroy -F nda1
dd if=/dev/zero of=/dev/nda1 bs=1M count=1

Thank you,

That doesn't seem to work.

Code Select Expand

root@OPNsense:~ # gpart destroy -F nda1
gpart: arg0 'nda1': Invalid argument


I did a bit more searching around and I came across a similar issue on a different system-forum:
https://www.truenas.com/community/threads/create-new-pool-ends-with-error-command-gpart-create-s-gpt-dev-ada0-returned-non-zero-exit-status-1.77775/

I did set

Code Select Expand

sysctl kern.geom.debugflags=16

and then I ran

Code Select Expand

gpart create -s gpt /dev/nda1
After that, I then was able to proceed with the instructions for adding the second NVME disk to Opnsense.

Now it looks like everything is complete.

When I go into zpool status, I can see both nda0p4 and nda1p4 listed.

Code Select Expand

root@OPNsense:~ # zpool status
  pool: zroot
 state: ONLINE
status: Some supported and requested features are not enabled on the pool.
        The pool can still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
        the pool may no longer be accessible by software that does not support
        the features. See zpool-features(7) for details.
