how to remove the log disk?

[3038922]

I used a virtual disk to mount the log disk But it will not automatically mount after the reboot.
So I used `zpool import -m pve1zfs2`command.
Because the problem of automatically attaching the virtual log disk cannot be solved, I decided not to use the log disk But he can't delete it now
This is how I added the log disk before
```
dd if=/dev/zero of=diskzfslog.img bs=4M count=25600
losetup /dev/loop7 ./diskzfslog.img
zpool add pve1Zfs2 log /dev/loop7
echo 180 | sudo tee /sys/module/zfs/parameters/zfs_txg_timeout
```

```

cannot remove loop7: checkpoint exists

Checkpoints are zpool-wide snapshots.

The documentation in man zpool-checkpoint describes how to delete it.
