Version 1.3.0.

This is the 1.3.0 release of tcmu-runner.

Release notes:

  • This release includes improved Ceph support by Red Hat and China Mobile.

Ceph support notes:

  1. HA setups should not be done manually with targetcli. The ceph-iscsi-cli tool is the preferred method. Setup and required setting documentation can be found here:

http://docs.ceph.com/docs/master/rbd/iscsi-overview/

  1. HA support requires the RHEL/CentOS 7.5 kernel; Linux kernel v4.16 or newer; or the Ceph iSCSI client test kernel. Instructions for getting the Ceph iSCSI client test kernel can be found on the manual install instructions here:

http://docs.ceph.com/docs/master/rbd/iscsi-target-cli-manual-install/

  1. Persistent Group Reservations (PGRs) and SCSI-2 Reserve/Release commands are not supported in HA tcmu-runner configurations.
  • Improved Gluster support by Red Hat.

See https://github.com/gluster/gluster-block for gluster tools that should be used.

  • Thanks to @lxbsz and China Mobile there is vSphere/ESXi VAAI support and tons of bug fixes.

vSphere support notes:

  1. In tcmu-runner HA configs "ATS-only" must be used (see https://docs.vmware.com/en/VMware-vSphere/6.0/com.vmware.vsphere.storage.doc/GUID-DE30AAE3-72ED-43BF-95B3-A2B885A713DB.html).

  2. Ceph iSCSI HA is only supported with vSphere 6.5 with vmfs 6 data stores. See the Ceph docs for setup instructions and required settings:

http://docs.ceph.com/docs/master/rbd/iscsi-initiators/

  1. vSphere HA support is under development. There is one last known issue where performance will be drop if one host lost its primary path but other hosts do not. See tcmu-runner issue: #341 for more details.

  • @bgly and IBM have added support for new commands including: WRITE_VERIFY, VERIFY, FORMAT and SYNCHRONIZE CACHE and have made many bug fixes to file_example, file_optical and tcmu-runner/libtcmu.

  • AIO support has been added by @vshankar at Red Hat.

  • Thanks to @tangwenji at ZTE for lots and lots of bug fixes.

  • Thanks to @mgerstner at SUSE for doing a security review and the patches.

  • Thanks to Jason Dillaman for rbd improvements and COMPARE_AND_WRITE offload support.

  • This release has dropped support for libtcmu 1.0. Versions 2.0 and on also no longer provide a stable API.
