Vitastor 2.1.0 released

2025-04-01

Separate cluster network support, RDMA-CM and allow_net_split setting.

New features

  • Support separate OSD cluster network - osd_cluster_network and, in general, multiple OSD networks, including RDMA
  • Add an alternative RDMA implementation via RDMA-CM - use_rdmacm, required for iWARP and, maybe, for some IB setups (but not for RoCE)
  • Change default PG behaviour to wait for all “up” OSDs to be connected before starting it. The old behaviour may be returned by enabling a new allow_net_split option.
  • Add a patch for QEMU 9.2

Bug fixes

  • Fix incorrect “has_xxx” PG state names in ls-pgs
  • Fix possible QEMU crashes after detaching of Vitastor disks (and update all QEMU builds in Vitastor repos)
  • Fix clients sometimes spamming OSDs with infinite reconnections when some PGs are offline
  • Fall back to TCP on RDMA connection failures
  • Add missing logging of RDMA ibv_modify_qp() errors
  • Add a minimum interval for etcd_state_client to reload state
