[SOLVED] Rename tank storage name in second node

[Davide Tomasini]

Hello everyone,
I have 2 node server (PVE1 - PVE2) with proxmox inside.

I need to clone my VM from PVE1 on PVE2.
But the operation don't done because in PVE2 doesn't exist the storage "Tank1"

Infact in PVE2 isn't Tank1 but is Tank2.

So... How can I rename tank2 in tank1 in PVE2 Storage?

dir: local
        path /var/lib/vz
        content backup,iso,vztmpl

zfspool: tank1
        pool tank1
        content images,rootdir
        nodes pve1

zfspool: local-zfs
        pool rpool/data
        content rootdir,images
        sparse 1

zfspool: tank2
        pool tank2
        content rootdir,images
        nodes pve2
        sparse 1

This is my storage.cfg in /etc/pve/storage.cfg
I edit this file but doesn't work... In LVM exist again tank2

Thanks a lot!

You can use 'zpool export' and 'zpool import' and choose a new name for the pool when importing. (see 'man zpool')

Ok... Don't work...
Can't mount tank2...
And now my zpool status is:

pool: rpool

  scan: none requested

I lost the name of the disk... (sda / sdb). PVE2 Work, but i havn't name but his serial... Why?

What were the concrete commands you executed? (Please post them in the correct order)
If you still have the output of those commands, please post them as well.
ZFS labels the disks with portable EFI labels (see 'man zpool' -> 'zpool export').

 

[Davide Tomasini]

zpool export tank2

zpool import tank1 (wrong name and zpool didn't make the operation "Cannot import 'tank1': no such pool available")

zpool import tank2 tank1 (Error "Cannot import 'tank2': no such pool available")

zpool status and exit the list without sda, sdb, sdc, sdd, ...

 

[mira]

You can list all pools available for import with just 'zpool import'. What is the output of 'zpool import' after a 'zpool export tank2'?

 

[Davide Tomasini]

   pool: tank2

It says 'The pool can be imported using its name or numeric identifier.'. You should be able to import it with 'zpool import tank2 tank1' as long as that's the case.
And I already mentioned the reason why it's no longer using 'sda' etc.. ZFS uses those labels for portability. This has no impact on operation.

 

[Davide Tomasini]

I try again... But it doesn't work.
"Cannot import 'tank2': no such pool available"

I also try

zpool export tank2
zpool import 7758790164637552920 tank1

cannot import '7758790164637552920': no such pool available

 

[mira]

In our tests here it works. Are there any error messages in dmesg or the journal?

 

[Davide Tomasini]

No logs error... Where can I find the zfs log?

 

[Davide Tomasini]

I think to resolve.
I need to use not only EXPORT and IMPORT zpools command, but also DETACH.

In my case i lost my VM, but in this moment isn't production status yet. So after changed the name, I cloned my default VM on PVE1 and restarted.

Thanks Mira again!
