Summary of the issue you are facing:

files_external can’t access Windows Storage Space disks.

about Storage Space :

Steps to replicate it (hint: details matter!):

Build an applicable Windows Server. (I reproduced it on Windows Server 2022 Standard or 2019 evaluation.)
Mount three or more test disks. If you want to do this with virtual disks, execute the following in diskpart.

create vdisk file=c:\disk00.vhdx maximum=16384 type=fixed
attach vdisk
create vdisk file=c:\disk01.vhdx maximum=16384 type=fixed
attach vdisk
create vdisk file=c:\disk02.vhdx maximum=16384 type=fixed
attach vdisk
create vdisk file=c:\disk03.vhdx maximum=16384 type=fixed
attach vdisk
exit

Create a pool of Storage Space. Execute the following command in PowerShell.

New-StoragePool -FriendlyName smbsharepool01 -PhysicalDisks (Get-PhysicalDisk |? {$_.CanPool}) -StorageSubSystemFriendlyName (Get-StorageSubSystem |? {$_.FriendlyName.StartsWith('Windows Storage') | Select-Object -First 1} |% {$_.FriendlyName})

Create a virtual disk of Storage Space. Execute the folloing command in PowerShell. (Set the number of disks that mounted step 2 to NumberOfColumns.)

New-VirtualDisk -StoragePoolFriendlyName smbsharepool01 -FriendlyName smbsharevdisk01 -UseMaximumSize -NumberOfColumns 4 -ResiliencySettingName Parity -ProvisioningType Fixed

Format and partition the virtual disk in PowerShell. (Set NewDriveLetter to your environment.)

$partition = Get-Disk -FriendlyName smbsharevdisk01 | Initialize-Disk -PassThru | New-Partition -UseMaximumSize
$partition | Format-Volume -FileSystem NTFS -Full:$false
$partition | Set-Partition -NewDriveLetter E

Create applicable directories and set access rights to share it.
(in PowerShell)

mkdir E:\smb01
icacls E:\smb01 /inheritance:r /grant 'Administrators:(CI)(OI)(F)' 'Authenticated Users:(CI)(OI)(M)' 'Everyone:(CI)(OI)(M)'

Create a smb share.
(in PowerShell)

New-SmbShare -FullAccess Administrators,'Authenticated Users',Everyone -Path E:\smb01 -Name smb01

on nextcloud server, create an external storage. (set Windows Server address or host name that built step 1 to host=.)

occ files_external:create --config host=192.168.64.40 --config share=smb01 --config root="" --config domain="" --config show_hidden=false --config case_sensitive=false --config check_acl=false --config user=Administrator --config password="***setpassword***" smb01 smb password::password

Verify configuration.
(set your mounted id to mount_id)

occ files_external:verify 1

expected:

The result of files_external:verify is following:

  - status: ok
  - code: 0
  - message

reproduced:

The result of files_external:verify is following:

  - status: error
  - code: 1
  - message

remarks01:

accessing smbclient was succeeded.

$ smbclient -U Administrator //192.168.64.40/smb01
Password for [WORKGROUP\Administrator]:
Try "help" to get a list of possible commands.
smb: \> ls

                11005695 blocks of size 4096. 10982565 blocks available
smb: \>

remarks02:

Except for the Storage Space virtual disk, same server shares as expected.

create smb share on C: drive in PowerShell.

mkdir C:\smb00
get-date | out-file C:\smb00\hereissmb00directory.txt # create a test file.
icacls C:\smb00 /inheritance:r /grant 'Administrators:(CI)(OI)(F)' 'Authenticated Users:(CI)(OI)(M)' 'Everyone:(CI)(OI)(M)'
New-SmbShare -FullAccess Administrators -ChangeAccess 'Authenticated Users','Everyone' -Path C:\smb00 -Name smb00

on nextcloud server, create an external storage.

occ files_external:create --config host=192.168.64.40 --config share=smb00 --config root="" --config domain="" --config show_hidden=false --config case_sensitive=false --config check_acl=false --config user=Administrator --config password="***setpassword***" smb00 smb password::password

Verify configuration.
(set your mounted id to mount_id)

occ files_external:verify 2

Then the result was expected.

  - status: ok
  - code: 0
  - message

Tips for increasing the likelihood of a response

Use the preformatted text formatting option in the editor for all log entries and configuration output.
If screenshots are useful, feel free to include them.
- If possible, also include key error output in text form so it can be searched for.
Try to edit log output only minimally (if at all) so that it can be ran through analyzers / formatters by those trying to help you.
