Description

Failure: https://pulpito.ceph.com/leonidus-2024-05-19_09:55:47-fs-wip-lusov-quiesce-distro-default-smithi/7713434/

Outstanding OPs at rank 0 (b) - hundreds of them. All quiesce_inode ops have the flag point

      "flag_point": "failed to authpin, subtree is being exported",

There is no trace of an ongoing export operation on either of the mds-es

Could this be just a very long export? However, it's more likely that there's some kind of deadlock with the quiescing, as the quiesce has completed on all other ranks

After analyzing this with @Patrick Donnelly we've concluded that the issue here is due to the remote authpining done by the quiesce on replicas. This prevents the migrator from reaching the tree frozen, while the quiesce may be stalled on some of the replicas due to freezing.
