Fixed In Version: ceph-16.2.8-2.el8cp
Doc Type: Bug Fix
Doc Text:
.The `tcmu-runner` daemons are no longer reported as stray daemons Previously, `tcmu-runner` daemons were not actively tracked by `cephadm` as they were considered part of iSCSI. This resulted in `tcmu-runner` daemons getting reported as stray daemons since `cephadm` was not tracking them. With this fix, when a `tcmu-runner` daemon matches up with a known iSCSI daemon, it is not marked as a stray daemon.

Comment 7 Preethi 2022-05-31 14:27:36 UTC 
Am not able to see the issue in the latest 5.2 ceph version
ceph version 16.2.8-22.el8cp

Tried the above steps as mentioned -
1. Install iscsi gateway
2. Configure iscsi target, block devices, added disks and exposed luns and ran IOs
