Fixed In Version: tcmu-runner-1.4.0-0.4.el7cp
Doc Type: Bug Fix
Doc Text:
.Discovering iSCSI paths during the boot, setup, or scanning process no longer causes the DM-Multipath feature to fail to set up During device and path setup, the initiator sent commands to all paths at the same time. This behavior caused the Ceph iSCSI gateways to take the RBD lock from one device and set it on another device. In some cases, the iSCSI gateway interpreted the lock being taken away in this manner as a hard error and escalated its error handler by dropping the iSCSI connection, reopening the RBD devices to clear old states, and then enabling the iSCSI target port group to allow a new iSCSI connection. This caused a disruption to the device and path discovery when disabling and enabling the iSCSI target port group. In turn, the multipath I/O layer continually was disabling and enabling all paths and I/O was suspended, or device and path discovery could fail and the device was not setup. This bug has been fixed, and rebooting an iSCSI initiator with connected devices no longer leads to this error.
