Can not Clone VM - reduce to less than 63 characters

[KevDog]

I tried cloning a jail this morning however received this error regarding the length to be more than 63 characters:


report_problem ValidationErrors
[ENAMETOOLONG] vm_create.devices.1.attributes.path: Disk path /dev/zvol/tank/VM/Arch/ArchZFSProxy/ArchZFSProxy-62jq1i_ArchZFSBW is too long, reduce to less than 63 characters

This was middleware error report:

Code:

Whats the deal with the 63 character limit? Why is that a limitation?
In addition the cloning function isn't working as I would expect.
The dataset I'm trying to clone is:
/dev/zvol/tank/VM/Arch/ArchZFSProxy/ArchZFSProxy-62jq1i

Please note that the GUI when I created this VM tacked on the -62jq1i lettering -- I have no idea where this came from.

When I selected clone - it said enter clone name and I enter ArchZFSBW. This resulted in the GUI creating:
/dev/zvol/tank/VM/Arch/ArchZFSProxy/ArchZFSProxy-62jq1i_ArchZFSBW

when I would have it expected it to be:
/dev/zvol/tank/VM/Arch/ArchZFSProxy/ArchZFSBW

I understand I can probably do all this manually, however GUI functionality is nice -- however in this case I don't think the implementation is correct.

@KevDog Did you figure this one out? I have run into a similar issue in TrueNAS Scale 21.06-BETA.1 when cloning a VM with the GUI.

Aha, now I see this one:

[How-To] Cloning new instances of a template VM for BHYVE

Background The use-case is rather straight forward. Rather than installing BHYVE VM instances from scratch every time, it would be nice to be able to configure once, and then clone to new VM instances every time we make a new deployment. I spend a few days researching this topic, and testing...

Thanks.

Well, this hapens when you have a full lenght to your installation media (caracters count bigger than 63 caracters) like me.
Example:
/mnt/Home_Storage/ISOs/PFsense/pfSense-CE-2.6.0-RELEASE-amd64.iso
[CARACTERES -->65]

Then i have changed my file to: "pfSense-CE-2.6.0.iso"
"/mnt/Home_Storage/ISOs/PFsense/pfSense-CE-2.6.0.iso" [CARACTERES-->51]

And Voialáaa
