Fixed In Version: tcmu-runner-1.5.4-4.el8cp
Doc Type: Bug Fix
Doc Text:
.The `tcmu-runner` no longer fails to remove “blocklist” entries Previously, the `tcmu-runner` would execute incorrect commands to remove the “blocklist” entries resulting in a degradation in performance for iSCSI LUNs. With this release, the `tcmu-runner` was updated to execute the correct command when removing blocklist entries. The blocklist entries are cleaned up by `tcmu-runner` and the iSCSI LUNs work as expected.
