Importing pool failes

[terenga]

I am having trouble importing a pool from Truenas Core in Truenas Scale 21.02-ALPHA.1

I am running Truenas Scale as VM on vSphere with passthrough of SAS2008 based controllers.

The error message I get is:
[ENOENT] Pool 2491833529097242126 not found.

At commandline "zpool import 2491833529097242126" works fine.

Another pool from the same Truenas Core machine imported without issues.

Full error message:

At commandline "zpool import 2491833529097242126" works fine.

And have you exported it after that before using the GUI to try again?

Can you import it by name?

Do you see the pool in good status with zpool import ?

 

[terenga]

In the GUI there is no option for choosing import by name or guid, but the name is shown. At the command line import by name works as well.

If I don't export the pool after importing at the command line it is not show at all in the GUI.

zpool import shows the pool

 

[sretalla]

zpool import shows the pool

With any errors?

Maybe you should try an import with a rename to see if that can clear it.

zpool import currentname newname

zpool export newname

import newname from GUI

Pay attention to avoid special characters in pool names.

Additionally a ticket on jira.ixsystems.com would be appreciated so some of the iX engineers can also take a look at the issue to see if there's some issue to resolve in the scale codebase :)

 

[terenga]

No errors show with zpool import

status: Some supported features are not enabled on the pool.
action: The pool can be imported using its name or numeric identifier, though
some features will not be available without an explicit 'zpool upgrade'.

Import and export with a new name does not help, based on the error message it looks like GUI is using id for import and not the name.

I will create a Jira ticket
