Hello, upgrade from v16.2.7 was successfully completed. There were only a few strange logs during the upgrade, like:

but it seems all fine. I can see iSCSI targets on dashboard.

> We're happy to announce the 8th backport release in the Pacific series. We recommend users to update to this release. For a detailed release notes with links & changelog please refer to the official blog entry at https://ceph.io/en/news/blog/2022/v16-2-8-pacific-released
>
> Notable Changes
> ---------------
>
> * MON/MGR: Pools can now be created with `--bulk` flag. Any pools created with `bulk` will use a profile of the `pg_autoscaler` that provides more performance from the start. However, any pools created without the `--bulk` flag will remain using it's old behavior by default. For more details, see: https://docs.ceph.com/en/latest/rados/operations/placement-groups/
>
> * MGR: The pg_autoscaler can now be turned `on` and `off` globally with the `noautoscale` flag. By default this flag is unset and the default pg_autoscale mode remains the same. For more details, see: https://docs.ceph.com/en/latest/rados/operations/placement-groups/
>
> * A health warning will now be reported if the ``require-osd-release`` flag is not set to the appropriate release after a cluster upgrade.
>
> * CephFS: Upgrading Ceph Metadata Servers when using multiple active MDSs requires ensuring no pending stray entries which are directories are present for active ranks except rank 0. See https://docs.ceph.com/en/latest/releases/pacific/#upgrading-from-octopus-or-nautilus.
