Fault enabling replication

Two test clusters on nodes tst-0 and tst-1

I have imported a remote on tst-1 into my cluster, giving it a name like this:

```
ubuntu@tst-1:~$ sudo microceph remote import --local-name tst0 tst0
```

I can see the remote from the tst-1 machine:

```
ubuntu@tst-1:~$ sudo ceph -s --cluster tst0 --id tst0
cluster:
id: 28260466-321a-44c2-b2aa-d8998d3c0fd7
health: HEALTH_WARN
1 pool(s) do not have an application enabled

services:
mon: 1 daemons, quorum tst-0 (age 25m)
mgr: tst-0(active, since 24m)
osd: 3 osds: 3 up (since 24m), 3 in (since 24m)

data:
pools: 2 pools, 33 pgs
objects: 3 objects, 577 KiB
usage: 81 MiB used, 5.9 GiB / 6 GiB avail
pgs: 33 active+clean
```

I have created a remote on the other end as well:

```
ubuntu@tst-0:~$ sudo ceph -s --cluster tst1 --id tst1
cluster:
id: 0a429727-8cf3-412f-b850-90343906716a
health: HEALTH_WARN
1 pool(s) do not have an application enabled

services:
mon: 1 daemons, quorum tst-1 (age 28m)
mgr: tst-1(active, since 28m)
osd: 3 osds: 3 up (since 27m), 3 in (since 27m)

data:
pools: 2 pools, 33 pgs
objects: 3 objects, 577 KiB
usage: 81 MiB used, 5.9 GiB / 6 GiB avail
pgs: 33 active+clean

```
But I can't enable rbd replication:

```
ubuntu@tst-1:~$ sudo microceph replication enable rbd rbd --remote tst0
Error: failed to process enable_replication request for rbd: failed to import peer bootstrap token: Failed to run: rbd mirror pool peer bootstrap import --site-name tst0 --direction rx-tx rbd /var/snap/microceph/1355/conf/rbd_mirror/tst0_peer_keyring --cluster tst0 --id tst0: exit status 22 (2025-05-15T13:39:19.814+0000 7f14775ff680 -1 librbd::api::Mirror: peer_bootstrap_import: cannot import token for duplicate site name

```
