zfs force import multiple VMS (IDs) and now can't find VM but it's not missing according to zfs?

I'm completely new to ZFS. Today, I did something stupid and caused a problem where I need to recover my entire OS. On a live OS I'm using to recover my machine, I need to mount my ZFS volumes for data transfer. I did the following:

root@kubuntu:/media/kubuntu/backup3-1tb/recovery# zpool import   pool: nas-2-mirror     id: 11643301469609613604  state: ONLINEstatus: The pool was last accessed by another system. action: The pool can be imported using its name or numeric identifier and        the '-f' flag.   see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-EY config:        nas-2-mirror                                               ONLINE          mirror-0                                                 ONLINE            usb-SanDisk_Extreme_55AE_32333135314D343031353938-0:0  ONLINE            usb-SanDisk_Extreme_55AE_32333135325A343030313338-0:0  ONLINE   pool: nas-1-mirror     id: 10379406262813511849  state: ONLINEstatus: The pool was last accessed by another system. action: The pool can be imported using its name or numeric identifier and        the '-f' flag.   see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-EY config:        nas-1-mirror                                               ONLINE          mirror-0                                                 ONLINE            usb-SanDisk_Extreme_55AE_32333135314D343031323130-0:0  ONLINE            usb-SanDisk_Extreme_55AE_323331363748343030333133-0:0  ONLINEroot@kubuntu:/media/kubuntu/backup3-1tb/recovery# zpool import -f    pool: nas-2-mirror     id: 11643301469609613604  state: ONLINEstatus: The pool was last accessed by another system. action: The pool can be imported using its name or numeric identifier and        the '-f' flag.   see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-EY config:        nas-2-mirror                                               ONLINE          mirror-0                                                 ONLINE            usb-SanDisk_Extreme_55AE_32333135314D343031353938-0:0  ONLINE            usb-SanDisk_Extreme_55AE_32333135325A343030313338-0:0  ONLINE   pool: nas-1-mirror     id: 10379406262813511849  state: ONLINEstatus: The pool was last accessed by another system. action: The pool can be imported using its name or numeric identifier and        the '-f' flag.   see: https://openzfs.github.io/openzfs-docs/msg/ZFS-8000-EY config:        nas-1-mirror                                               ONLINE          mirror-0                                                 ONLINE            usb-SanDisk_Extreme_55AE_32333135314D343031323130-0:0  ONLINE            usb-SanDisk_Extreme_55AE_323331363748343030333133-0:0  ONLINEroot@kubuntu:/media/kubuntu/backup3-1tb/recovery# zpool import -f 11643301469609613604 10379406262813511849cannot import '10379406262813511849': name must begin with a letterroot@kubuntu:/media/kubuntu/backup3-1tb/recovery# zpool import -f nas-1-mirror nas-2-mirror  <<<==== THIS

Now nas-2-mirror is fine!

root@kubuntu:~# zpool status  pool: nas-2-mirror state: ONLINEconfig:        NAME                                                       STATE     READ WRITE CKSUM        nas-2-mirror                                               ONLINE       0     0     0          mirror-0                                                 ONLINE       0     0     0            usb-SanDisk_Extreme_55AE_32333135314D343031323130-0:0  ONLINE       0     0     0            usb-SanDisk_Extreme_55AE_323331363748343030333133-0:0  ONLINE       0     0     0errors: No known data errors

However, nas-1-mirror is nowhere to be found. I tried to re-import it using its ID:

root@kubuntu:~# zpool import -f 10379406262813511849cannot import '10379406262813511849': a pool with that name already existsuse the form 'zpool import <pool | id> <newpool>' to give it a new nameroot@kubuntu:~# zpool listNAME           SIZE  ALLOC   FREE  CKPOINT  EXPANDSZ   FRAG    CAP  DEDUP    HEALTH  ALTROOTnas-2-mirror  1.81T  40.1G  1.77T        -         -     0%     2%  1.00x    ONLINE  -

I thought maybe I borked the name of the volume by importing two volumes at once, so I took the help advice from the import above and tried re-naming the volume

root@kubuntu:~# zpool import -f 10379406262813511849 nas-1-mirrorcannot import '10379406262813511849': no such pool available

I thought maybe I could attempt to just mount it?

root@kubuntu:~# zfs mount nas-1-mirrorcannot open 'nas-1-mirror': dataset does not existroot@kubuntu:~# zfs list -o name,canmount,mountpointNAME          CANMOUNT  MOUNTPOINTnas-2-mirror  on        /nas/nas-media

I'm a little concerned. Anyone have anything else I can try?

EDIT

Ah hah! I see what I did. My import renamed the ID to the ID used in the second param in my arguments there.

root@kubuntu:~# zpool list -o guid nas-2-mirror GUID10379406262813511849

So I need to figure out how to undo this.

https://forums.freebsd.org/threads/renaming-zfs-pool-via-zpool-import-mypool-newpoolname.46300/ is relevant (second question), but there is no clear answer on how to fix the problem. I attempted to use zpool import -fa but I get:

root@kubuntu:~# zpool import -facannot import 'nas-2-mirror': pool already exists

POSSIBLE SOLUTION

I can't try this yet, but maybe: https://illumos.org/books/zfs-admin/gavwn.html

section: 4.1.1. Using Disks in a ZFS Storage Pool

If you inadvertently change both the path and the ID of the device, then export and re-import the pool in order to use it.

When I can, I'll try that suggestion and see where that gets me. I'll post accordingly.

I also see that zfs exposes a rename command, so I'll try this too:

zfs rename 10379406262813511849 nas-1-mirror

after I'm done with operation I'm working. I don't want to inadvertently mess with anything.
